Notes: 1. The HI08 port supports a non-multiplexed or a multiplexed bus, single or double Data Strobe (DS), and single or  
double Host Request (HR) configurations. Since each of these modes is configured independently, any combination  
of these modes is possible. These HI08 signals can also be configured alternatively as GPIO signals (PB[0–15]).  
Signals with dual designations (for example, HAS/HAS) have configurable polarity.  
2. The ESSI0, ESSI1, and SCI signals are multiplexed with the Port C GPIO signals (PC[0–5]), Port D GPIO signals  
(PD[0–5]), and Port E GPIO signals (PE[0–2]), respectively.  
3. TIO[0–2] can be configured as GPIO signals.  
4. Ground connections shown in this figure are for the TQFP package. In the MAP-BGA package, in addition to the  
GNDP and GNDP1 connections, there are 64 GND connections to a common internal package ground plane.

Address Attribute—When defined as AA, these signals can be used as chip selects or  
additional address lines. The default use defines a priority scheme under which only  
one AA signal can be asserted at a time. Setting the AA priority disable (APD) bit (Bit  
14) of the Operating Mode Register, the priority mechanism is disabled and the lines  
can be used together as four external lines that can be decoded externally into 16 chip  
select signals.

Row Address Strobe—When defined as RAS, these signals can be used as RAS for  
DRAM interface. These signals are tri-statable outputs with programmable polarity.

Input  
Tri-stated  
Write Enable—When the DSP is the bus master, WR is an active-low output that is  
asserted to write external memory on the data bus (D[0–23]). Otherwise, the signals  
are tri-stated.  
Ignored Input  
Transfer Acknowledge—If the DSP56303 is the bus master and there is no external  
bus activity, or the DSP56303 is not the bus master, the TA input is ignored. The TA  
input is a data transfer acknowledge (DTACK) function that can extend an external bus  
cycle indefinitely. Any number of wait states (1, 2. . .infinity) can be added to the wait  
states inserted by the bus control register (BCR) by keeping TA deasserted. In typical  
operation, TA is deasserted at the start of a bus cycle, is asserted to enable completion  
of the bus cycle, and is deasserted before the next bus cycle. The current bus cycle  
completes one clock period after TA is asserted synchronous to CLKOUT. The number  
of wait states is determined by the TA input or by the BCR, whichever is longer. The  
BCR can be used to set the minimum number of wait states in external bus cycles.  
To use the TA functionality, the BCR must be programmed to at least one wait state. A  
zero wait state access cannot be extended by TA deassertion; otherwise, improper  
operation may result. TA can operate synchronously or asynchronously depending on  
the setting of the TAS bit in the Operating Mode Register. TA functionality cannot be  
used during DRAM type accesses; otherwise improper operation may result.

(deasserted)  
Bus Request—Asserted when the DSP requests bus mastership. BR is deasserted  
when the DSP no longer needs the bus. BR may be asserted or deasserted  
independently of whether the DSP56303 is a bus master or a bus slave. Bus “parking”  
allows BR to be deasserted even though the DSP56303 is the bus master. (See the  
description of bus “parking” in the BB signal description.) The bus request hold (BRH)  
bit in the BCR allows BR to be asserted under software control even though the DSP  
does not need the bus. BR is typically sent to an external bus arbitrator that controls the  
priority, parking, and tenure of each master on the same external bus. BR is affected  
State during Stop/Wait

setting:  
• BRH = 0: Output,  
deasserted  
• BRH = 1: Maintains last only by DSP requests for the external bus, never for the internal bus. During hardware  
state (that is, if asserted,  
remains asserted)  
reset, BR is deasserted and the arbitration is reset to the bus slave state.

Signal Description  
Name  
BG  
Input  
Ignored Input  
Bus Grant—Asserted by an external bus arbitration circuit when the DSP56303  
becomes the next bus master. When BG is asserted, the DSP56303 must wait until BB  
is deasserted before taking bus mastership. When BG is deasserted, bus mastership is  
typically given up at the end of the current bus cycle. This may occur in the middle of an  
instruction that requires more than one external bus cycle for execution.  
The default operation of this bit requires a setup and hold time as specified in Table 2-  
14. An alternate mode can be invoked: set the asynchronous bus arbitration enable  
(ABE) bit (Bit 13) in the Operating Mode Register. When this bit is set, BG and BB are  
synchronized internally. This eliminates the respective setup and hold time  
requirements but adds a required delay between the deassertion of an initial BG input  
and the assertion of a subsequent BG input.  
BB  
Input/  
Output  
Ignored Input  
Bus Busy—Indicates that the bus is active. Only after BB is deasserted can the  
pending bus master become the bus master (and then assert the signal again). The  
bus master may keep BB asserted after ceasing bus activity regardless of whether BR  
is asserted or deasserted. Called “bus parking,” this allows the current bus master to  
reuse the bus without rearbitration until another device requires the bus. BB is  
deasserted by an “active pull-up” method (that is, BB is driven high and then released  
and held high by an external pull-up resistor).  
The default operation of this signal requires a setup and hold time as specified in Table  
2-14. An alternative mode can be invoked by setting the ABE bit (Bit 13) in the  
Operating Mode Register. When this bit is set, BG and BB are synchronized internally.  
See BG for additional information.  
Note: BB requires an external pull-up resistor.

When the DSP is the bus master, BCLK is active when the Operating Mode Register

1.7 Host Interface (HI08)  
The HI08 provides a fast, 8-bit, parallel data port that connects directly to the host bus. The HI08 supports a variety  
of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs,  
and DMA hardware.  
1.7.1 Host Port Usage Considerations  
Careful synchronization is required when the system reads multiple-bit registers that are written by another  
asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the  
Host port). The considerations for proper operation are discussed in Table 1-10.  
Table 1-10. Host Port Usage Considerations  
Action  
Description  
Asynchronous read of receive byte  
registers  
When reading the receive byte registers, Receive register High (RXH), Receive register Middle  
(RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll  
the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data  
in the receive byte registers is valid.  
Asynchronous write to transmit byte  
registers  
The host interface programmer should not write to the transmit byte registers, Transmit register High  
(TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register  
Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees  
that the transmit byte registers transfer valid data to the Host Receive (HRX) register.  
Asynchronous write to host vector  
The host interface programmer must change the Host Vector (HV) register only when the Host  
Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a  
stable vector.  
1.7.2 Host Port Configuration  
HI08 signal functions vary according to the programmed configuration of the interface as determined by the 16 bits

Notes: 1. In the Stop state, the signal maintains the last state as follows:  
• If the last state is input, the signal is an ignored input.  
• If the last state is output, the signal is tri-stated.  
2. The Wait processing state does not affect the signal state.  
3. All inputs are 5 V tolerant.

1.12 JTAG and OnCE Interface  
The DSP56300 family and in particular the DSP56303 support circuit-board test strategies based on the IEEE®  
Std. 1149.1™ test access port and boundary scan architecture, the industry standard developed under the  
sponsorship of the Test Technology Committee of IEEE and the JTAG. The OnCE module provides a means to  
interface nonintrusively with the DSP56300 core and its peripherals so that you can examine registers, memory, or  
on-chip peripherals. Functions of the OnCE module are provided through the JTAG TAP signals. For programming  
models, see the chapter on debugging support in the DSP56300 Family Manual.

Test Reset—Initializes the test controller asynchronously. TRST has an  
internal pull-up resistor. TRST must be asserted after powerup.  
Input/ Output  
(open-drain)  
Debug Event—As an input, initiates Debug mode from an external command  
controller, and, as an open-drain output, acknowledges that the chip has  
entered Debug mode. As an input, DE causes the DSP56300 core to finish  
executing the current instruction, save the instruction pipeline information,  
enter Debug mode, and wait for commands to be entered from the debug  
serial input line. This signal is asserted as an output for three clock cycles  
when the chip enters Debug mode as a result of a debug request or as a result  
of meeting a breakpoint condition. The DE has an internal pull-up resistor.  
This signal is not a standard part of the JTAG TAP controller. The signal  
connects directly to the OnCE module to initiate debug mode directly or to  
provide a direct external indication that the chip has entered Debug mode. All  
other interface with the OnCE module must occur through the JTAG port.  
Note: All inputs are 5 V tolerant.

The DSP56303 is fabricated in high-density CMOS with transistor-transistor logic (TTL) compatible inputs and outputs.  
2.1 Maximum Ratings  
CAUTION  
This device contains circuitry protecting  
against damage due to high static voltage or  
electrical fields; however, normal precautions  
should be taken to avoid exceeding maximum  
voltage ratings. Reliability is enhanced if  
unused inputs are tied to an appropriate logic  
voltage level (for example, either GND or V ).  
CC  
In the calculation of timing requirements, adding a maximum value of one specification to a minimum value of  
another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case  
variation of process parameter values in one direction. The minimum specification is calculated using the worst  
case for the same parameters in the opposite direction. Therefore, a “maximum” value for a specification never  
occurs in the same device that has a “minimum” value for another specification; adding a maximum to a minimum  
represents a condition that can never exist.

Notes: 1. Absolute maximum ratings are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond  
the maximum rating may affect device reliability or cause permanent damage to the device.  
2. At power-up, ensure that the voltage difference between the 5 V tolerant pins and the chip VCC never exceeds 3.5 V.

2. Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. In order to obtain these  
results, all inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP  
benchmarks (see Appendix A). The power consumption numbers in this specification are 90 percent of the measured results  
of this benchmark. This reflects typical DSP applications. Typical internal supply current is measured with VCC = 3.3 V at TJ =  
100°C.  
3. In order to obtain these results, all inputs must be terminated (that is, not allowed to float).  
4. In order to obtain these results, all inputs that are not disconnected at Stop mode must be terminated (that is, not allowed to  
float). PLL and XTAL signals are disabled during Stop state.  
5. Periodically sampled and not 100 percent tested.  
6.  
VCC = 3.3 V ± 0.3 V; TJ = –40°C to +100 °C, CL = 50 pF  
7. This characteristic does not apply to XTAL and PCAP.  
8. Driving EXTAL to the low VIHX or the high VILX value may cause additional power consumption (DC current). To minimize  
power consumption, the minimum VIHX should be no lower than  
0.9 × VCC and the maximum VILX should be no higher than 0.1 × VCC  
.
2.5 AC Electrical Characteristics  
The timing waveforms shown in the AC electrical characteristics section are tested with a V maximum of 0.3 V  
IL  
and a V minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Note 6 of  
IH  
the previous table. AC timing specifications, which are referenced to a device input signal, are measured in  
production with respect to the 50 percent point of the respective input signal transition. DSP56303 output levels are  
measured with the production test machine V and V reference levels set at 0.4 V and 2.4 V, respectively.

Note: Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 15

2.5.2 External Clock Operation  
The DSP56303 system clock is derived from the on-chip oscillator or is externally supplied. To use the on-chip  
oscillator, connect a crystal and associated resistor/capacitor components to EXTAL and XTAL; examples are  
shown in Figure 2-1.

C = 22 pF ± 20%  
Note: Make sure that in  
the PCTL Register:  
XTLD (bit 16) = 0  
If fOSC > 200 kHz,  
XTLR (bit 15) = 0

If an externally-supplied square wave voltage source is used, disable the internal oscillator circuit during bootup by  
setting XTLD (PCTL Register bit 16 = 1—see the DSP56303 User’s Manual). The external square wave source  
connects to EXTAL; XTAL is not physically connected to the board or socket. Figure 2-2 shows the relationship  
between the EXTAL input and the internal clock and CLKOUT.

4. The maximum value for PLL enabled is given for minimum VCO frequency and maximum DF.  
5. The skew is not guaranteed for any other MF value.  
6. The indicated duty cycle is for the specified maximum frequency for which a part is rated. The minimum clock high or low time  
required for correction operation, however, remains the same at lower operating frequencies; therefore, when a lower clock  
frequency is used, the signal symmetry may vary from the specified duty cycle as long as the minimum high time and low time  
requirements are met.

Notes: 1. When fast interrupts are used and IRQA, IRQB, IRQC, and IRQD are defined as level-sensitive, timings 19 through 21 apply to  
prevent multiple interrupt service. To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended  
when fast interrupts are used. Long interrupts are recommended for Level-sensitive mode.  
2. This timing depends on several settings:  
• For PLL disable, using internal oscillator (PLL Control Register (PCTL) Bit 16 = 0) and oscillator disabled during Stop (PCTL  
Bit 17 = 0), a stabilization delay is required to assure that the oscillator is stable before programs are executed. Resetting the  
Stop delay (Operating Mode Register Bit 6 = 0) provides the proper delay. While Operating Mode Register Bit 6 = 1 can be set,  
it is not recommended, and these specifications do not guarantee timings for that case.  
• For PLL disable, using internal oscillator (PCTL Bit 16 = 0) and oscillator enabled during Stop (PCTL Bit 17=1), no  
stabilization delay is required and recovery is minimal (Operating Mode Register Bit 6 setting is ignored).  
• For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time is defined by the  
PCTL Bit 17 and Operating Mode Register Bit 6 settings.  
• For PLL enable, if PCTL Bit 17 is 0, the PLL is shutdown during Stop. Recovering from Stop requires the PLL to get locked.  
The PLL lock procedure duration, PLL Lock Cycles (PLC), may be in the range of 0 to 1000 cycles. This procedure occurs in  
parallel with the stop delay counter, and stop recovery ends when the last of these two events occurs. The stop delay counter  
completes count or PLL lock procedure completion.  
• PLC value for PLL disable is 0.  
• The maximum value for ETC is 4096 (maximum MF) divided by the desired internal frequency (that is, for 66 MHz it is 4096/66  
MHz = 62 µs). During the stabilization period, TC, TH, and TL is not constant, and their width may vary, so timing may vary as  
well.  
3. Periodically sampled and not 100 percent tested.  
4. Value depends on clock source:  
• For an external clock generator, RESET duration is measured while RESET is asserted, VCC is valid, and the EXTAL input is  
active and valid.  
• For an internal oscillator, RESET duration is measured while RESET is asserted and VCC is valid. The specified timing  
reflects the crystal oscillator stabilization time after power-up. This number is affected both by the specifications of the crystal  
and other components connected to the oscillator and reflects worst case conditions.  
• When the VCC is valid, but the other “required RESET duration” conditions (as specified above) have not been yet met, the  
device circuitry is in an uninitialized state that can result in significant power consumption and heat-up. Designs should  
minimize this state to the shortest possible duration.  
5. If PLL does not lose lock.  
6.  
VCC = 3.3 V ± 0.3 V; TJ = –40°C to +100°C, CL = 50 pF.  
7. WS = number of wait states (measured in clock cycles, number of TC).  
8. Use the expression to compute a maximum value.

2.5.5.2 DRAM Timing  
The selection guides in Figure 2-14 and Figure 2-17 are for primary selection only. Final selection should be based  
on the timing in the following tables. For example, the selection guide suggests that four wait states must be used  
for 100 MHz operation with Page Mode DRAM. However, consulting the appropriate table, a designer can evaluate  
whether fewer wait states might suffice by determining which timing prevents operation at 100 MHz, running the  
chip at a slightly lower frequency (for example, 95 MHz), using faster DRAM (if it becomes available), and  
manipulating control factors such as capacitive and resistive load to improve overall system performance.  
Note:  
This figure should be used for primary selection. For exact  
and detailed timings, see the following tables.

3. WS is the number of wait states specified in the BCR.  
4. If WS > 1, WR assertion refers to the next rising edge of CLKOUT.  
5. Use the expression to compute the maximum or minimum value listed, as appropriate. For timing 210, the minimum is an

6. T198 and T199 are valid for Address Trace mode if the ATE bit in the Operating Mode Register is set. when this mode is  
enabled, use the status of BR (See T212) to determine whether the access referenced by A[0–17] is internal or external.

Notes: 1. Bit 13 in the Operating Mode Register must be set to enter Asynchronous Arbitration mode.  
2. If Asynchronous Arbitration mode is active, none of the timings in Table 2-14 is required.  
3. An expression is used to compute the maximum or minimum value listed, as appropriate.  
4. Asynchronous Arbitration mode is recommended for operation at 100 MHz.  
5. In order to guarantee timings 250, and 251, BG inputs must be asserted to different DSP56300 devices on the same bus in the  
non-overlap manner shown in Figure 2-26.

Figure 2-26. Asynchronous Bus Arbitration Timing  
The asynchronous bus arbitration is enabled by internal synchronization circuits on BG and BB inputs. These  
synchronization circuits add delay from the external signal until it is exposed to internal logic. As a result of this  
delay, a DSP56300 part may assume mastership and assert BB, for some time after BG is deasserted. This is the  
reason for timing 250.  
Once BB is asserted, there is a synchronization delay from BB assertion to the time this assertion is exposed to other  
DSP56300 components that are potential masters on the same bus. If BG input is asserted before that time, and BG  
is asserted and BB is deasserted, another DSP56300 component may assume mastership at the same time.  
Therefore, some non-overlap period between one BG input active to another BG input active is required. Timing 251  
ensures that overlaps are avoided.

Notes: 1. See the Programmer’s Model section in the chapter on the HI08 in the DSP56303 User’s Manual.  
2. In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable.  
3. This timing is applicable only if two consecutive reads from one of these registers are executed.  
4. The data strobe is Host Read (HRD) or Host Write (HWR) in the Dual Data Strobe mode and Host Data Strobe (HDS) in the  
Single Data Strobe mode.  
5. The read data strobe is HRD in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.  
6. The write data strobe is HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.  
7. The host request is HREQ in the Single Host Request mode and HRRQ and HTRQ in the Double Host Request mode.  
8. The “Last Data Register” is the register at address $7, which is the last location to be read or written in data transfers. This is  
RXL/TXL in the Big Endian mode (HLEND = 0; HLEND is the Interface Control Register bit 7—ICR[7]), or RXH/TXH in the  
Little Endian mode (HLEND = 1).  
9. In this calculation, the host request signal is pulled up by a 4.7 kresistor in the Open-drain mode.  
10.  
VCC = 3.3 V ± 0.3 V; TJ = –40°C to +100 °C, CL = 50 pF  
11. This timing is applicable only if a read from the “Last Data Register” is followed by a read from the RXL, RXM, or RXH registers  
without first polling RXDF or HREQ bits, or waiting for the assertion of the HREQ signal.  
12. After the external host writes a new value to the ICR, the HI08 is ready for operation after three DSP clock cycles (3 × Tc).

Notes: 1. For the internal clock, the external clock cycle is defined by Icyc (see Timing 7) and the ESSI Control Register.  
2. The word-length-relative frame sync signal waveform operates the same way as the bit-length frame sync signal waveform,  
but spreads from one serial clock before the first bit clock (same as the Bit Length Frame Sync signal) until the one before last  
bit clock of the first word in the frame.  
3. Periodically sampled and not 100 percent tested  
4.  
VCC = 3.3 V ± 0.3 V; TJ = 40°C to +100 °C, CL = 50 pF  
5. TXC (SCK Pin) = transmit clock  
RXC (SC0 or SCK pin) = receive clock  
FST (SC2 pin) = transmit frame sync  
FSR (SC1 or SC2 pin) receive frame sync  
6. i ck = internal clock  
x ck = external clock  
i ck a = internal clock, Asynchronous mode  
(asynchronous implies that TXC and RXC are two different clocks)  
i ck s = Internal Clock, Synchronous mode  
(synchronous implies that TXC and RXC are the same clock)  
7. bl = bit length; wl = word length; wr = word length relative.  
8. If the DSP core writes to the transmit register during the last cycle before causing an underrun error, the delay is 20 ns + (0.5  
× TC).  
9. An expression is used to compute the number listed as the minimum or maximum value as appropriate.

Notes: Signal names are based on configured functionality. Most pins supply a single signal. Some pins provide a signal with dual  
functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted but act as interrupt lines during  
operation. Some signals have configurable polarity; these names are shown with and without overbars, such as HAS/HAS. Some  
pins have two or more configurable functions; names assigned to these pins indicate the function for a specific configuration. For  
example, Pin 34 is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7  
when the GPIO function is enabled for this pin.

Notes: Signal names are based on configured functionality. Most connections supply a single signal. Some connections  
provide a signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is  
deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are  
shown with and without overbars, such as HAS/HAS. Some connections have two or more configurable functions;  
names assigned to these connections indicate the function for a specific configuration. For example, connection N2  
is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7  
when the GPIO function is enabled for this pin. Unlike in the TQFP package, most of the GND pins are connected  
internally in the center of the connection array and act as heat sink for the chip. Therefore, except for GND and  
P
GND that support the PLL, other GND signals do not support individual subsystems in the chip.

Design Considerations  
4
This section describes various areas to consider when incorporating the DSP56303 device into a system design.  
4.1 Thermal Design Considerations  
An estimate of the chip junction temperature, T , in ° C can be obtained from this equation:  
J
Equation 1: TJ = TA + (PD × RθJA  
±
Where:  
T
=
=
=

D
Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-  
to-ambient thermal resistance, as in this equation:  
Equation 2: RθJA = RθJC + RθCA  
Where:  
R

θCA  
R
is device-related and cannot be influenced by the user. The user controls the thermal environment to change  
θJC  
the case-to-ambient thermal resistance, R  
. For example, the user can change the air flow around the device, add  
θCA  
a heat sink, change the mounting arrangement on the printed circuit board (PCB) or otherwise change the thermal  
dissipation capability of the area surrounding the device on a PCB. This model is most useful for ceramic packages  
with heat sinks; some 90 percent of the heat flow is dissipated through the case to the heat sink and out to the  
ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case  
and an alternate path through the PCB, analysis of the device thermal performance may need the additional  
modeling capability of a system-level thermal simulation tool.  
The thermal performance of plastic packages is more dependent on the temperature of the PCB to which the  
package is mounted. Again, if the estimates obtained from R  
do not satisfactorily answer whether the thermal  
θJA  
performance is adequate, a system-level model may be appropriate.  
A complicating factor is the existence of three common ways to determine the junction-to-case thermal resistance  
in plastic packages.  
To minimize temperature variation across the surface, the thermal resistance is measured from the junction  
to the outside surface of the package (case) closest to the chip mounting area when that surface has a  
proper heat sink.

Design Considerations  
To define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is  
measured from the junction to the point at which the leads attach to the case.  
If the temperature of the package case (T ) is determined by a thermocouple, thermal resistance is  
T
computed from the value obtained by the equation (T – T )/P .  
J
T
D
As noted earlier, the junction-to-case thermal resistances quoted in this data sheet are determined using the first  
definition. From a practical standpoint, that value is also suitable to determine the junction temperature from a case  
thermocouple reading in forced convection environments. In natural convection, the use of the junction-to-case  
thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will  
yield an estimate of a junction temperature slightly higher than actual temperature. Hence, the new thermal metric,  
thermal characterization parameter or Ψ , has been defined to be (T – T )/P . This value gives a better estimate of  
JT  
J
T
D
the junction temperature in natural convection when the surface temperature of the package is used. Remember that  
surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the  
sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40-  
gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.  
4.2 Electrical Design Considerations  
CAUTION  
This device contains protective circuitry to  
guard against damage due to high static  
voltage or electrical fields. However, normal  
precautions are advised to avoid application  
of any voltages higher than maximum rated  
voltages to this high-impedance circuit.  
Reliability of operation is enhanced if unused  
inputs are tied to an appropriate logic voltage  
level (for example, either GND or V ).  
CC  
Use the following list of recommendations to ensure correct DSP operation.  
Provide a low-impedance path from the board power supply to each VCC pin on the DSP and from the  
board ground to each GND pin.  
Use at least six 0.01–0.1 µF bypass capacitors positioned as close as possible to the four sides of the  
package to connect the VCC power source to GND.  
Ensure that capacitor leads and associated printed circuit traces that connect to the chip VCC and GND pins  
are less than 0.5 inch per capacitor lead.  
Use at least a four-layer PCB with two inner layers for VCC and GND.  
Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal. This  
recommendation particularly applies to the address and data buses as well as the IRQA, IRQB, IRQC, IRQD,  
TA, and BG pins. Maximum PCB trace lengths on the order of 6 inches are recommended.

Power Consumption Considerations  
Consider all device loads as well as parasitic capacitance due to PCB traces when you calculate  
capacitance. This is especially critical in systems with higher capacitive loads that could create higher  
transient currents in the VCC and GND circuits.  
All inputs must be terminated (that is, not allowed to float) by CMOS levels except for the three pins with  
internal pull-up resistors (TRST, TMS, DE).  
Take special care to minimize noise levels on the VCCP, GND , and GNDP1 pins.  
P
The following pins must be asserted after power-up: RESET and TRST.  
If multiple DSP devices are on the same board, check for cross-talk or excessive spikes on the supplies due  
to synchronous operation of the devices.  
RESET must be asserted when the chip is powered up. A stable EXTAL signal should be supplied before  
deassertion of RESET.  
At power-up, ensure that the voltage difference between the 5 V tolerant pins and the chip V never  
CC  
exceeds 3.5 V.  
4.3 Power Consumption Considerations  
Power dissipation is a key issue in portable DSP applications. Some of the factors affecting current consumption  
are described in this section. Most of the current consumed by CMOS devices is alternating current (ac), which is  
charging and discharging the capacitances of the pins and internal nodes.  
Current consumption is described by this formula:  
Equation 3: I = C × V × f  
Where:  
C
V
f
=
=
=
node/pin capacitance

frequency of node/pin toggle  
Example 4-1. Current Consumption  
For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, with a 66 MHz clock, toggling at its maximum possible rate (33  
MHz), the current consumption is expressed in Equation 4.  
Equation 4: I = 50 × 10–12 × 3.3 × 33 × 106 = 5.48 mA  
The maximum internal current (I max) value reflects the typical possible switching of the internal buses on best-  
CCI  
case operation conditions—not necessarily a real application case. The typical internal current (I  
reflects the average switching of the internal buses on typical operating conditions.  
) value  
CCItyp  
Perform the following steps for applications that require very low current consumption:  
1. Set the EBD bit when you are not accessing external memory.  
2. Minimize external memory accesses, and use internal memory accesses.  
3. Minimize the number of pins that are switching.  
4. Minimize the capacitive load on the pins.  
5. Connect the unused inputs to pull-up or pull-down resistors.

Design Considerations  
6. Disable unused peripherals.  
7. Disable unused pin activity (for example, CLKOUT, XTAL).  
One way to evaluate power consumption is to use a current-per-MIPS measurement methodology to minimize  
specific board effects (that is, to compensate for measured board current not caused by the DSP). A benchmark  
power consumption test algorithm is listed in Appendix A. Use the test algorithm, specific test current  
measurements, and the following equation to derive the current-per-MIPS value.  
Equation 5: I MIPS = I MHz = (ItypF2 ItypF1± ⁄ (F2 – F1±  
Where:

high frequency (any specified operating frequency)  
low frequency (any specified operating frequency lower than F2)  
Note: F1 should be significantly less than F2. For example, F2 could be 66 MHz and F1 could be 33 MHz. The  
degree of difference between F1 and F2 determines the amount of precision with which the current rating  
can be determined for an application.  
4.4 PLL Performance Issues  
The following explanations should be considered as general observations on expected PLL behavior. There is no  
test that replicates these exact numbers. These observations were measured on a limited number of parts and were  
not verified over the entire temperature and voltage ranges.  
4.4.1 Phase Skew Performance  
The phase skew of the PLL is defined as the time difference between the falling edges of EXTAL and CLKOUT for a  
given capacitive load on CLKOUT, over the entire process, temperature and voltage ranges. As defined in Figure 2-  
2, External Clock Timing, on page 2-5 for input frequencies greater than 15 MHz and the MF 4, this skew is  
greater than or equal to 0.0 ns and less than 1.8 ns; otherwise, this skew is not guaranteed. However, for MF < 10  
and input frequencies greater than 10 MHz, this skew is between 1.4 ns and +3.2 ns.  
4.4.2 Phase Jitter Performance  
The phase jitter of the PLL is defined as the variations in the skew between the falling edges of EXTAL and CLKOUT  
for a given device in specific temperature, voltage, input frequency, MF, and capacitive load on CLKOUT. These  
variations are a result of the PLL locking mechanism. For input frequencies greater than 15 MHz and MF 4, this  
jitter is less than ±0.6 ns; otherwise, this jitter is not guaranteed. However, for MF < 10 and input frequencies  
greater than 10 MHz, this jitter is less than ±2 ns.  
4.4.3 Frequency Jitter Performance  
The frequency jitter of the PLL is defined as the variation of the frequency of CLKOUT. For small MF (MF < 10)  
this jitter is smaller than 0.5 percent. For mid-range MF (10 < MF < 500) this jitter is between 0.5 percent and  
approximately 2 percent. For large MF (MF > 500), the frequency jitter is 2–3 percent.

Freescale Semiconductor  
Input (EXTAL) Jitter Requirements  
4.5 Input (EXTAL) Jitter Requirements  
The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow  
(that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is  
fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase  
and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
