to deselect the device when desired. If any one of these three are not  
asserted when ADV/LD is low, no new memory operation can be  
initiated. However, any pending data transfers (reads or writes) will be  
completed. The data bus will tri-state two cycles after chip is deselected  
or a write is initiated.  
TheIDT71V65603/5803haveanon-chipburstcounter.Intheburst  
mode, the IDT71V65603/5803 can provide four cycles of data for a  
single address presented to the SRAM. The order of the burst  
sequence is defined by the LBO input pin. The LBO pin selects  
between linear and interleaved burst sequence. The ADV/LD signal is  
used to load a new external address (ADV/LD = LOW) or increment  
the internal burst counter (ADV/LD = HIGH).

The IDT71V65603/5803 SRAM utilize IDT's latest high-performance  
CMOS process, and are packaged in a JEDEC Standard 14mm x 20mm  
100-pin thin plastic quad flatpack (TQFP) as well as a 119 ball grid array  
(BGA) and 165 fine pitch ball grid array (fBGA) .

Address Inputs  
I
N/A  
Synchronous Address inputs. The address register is triggered by a combination of the  
rising edge of CLK, ADV/LD low, CEN low, and true chip enables.  
ADV/LD  
Advance / Load  
I
N/A  
ADV/LD is a synchronous input that is used to load the internal registers with new address  
and control when it is sampled low at the rising edge of clock with the chip selected. When  
ADV/LD is low with the chip deselected, any burst in progress is terminated. When ADV/LD  
is sampled high then the internal burst counter is advanced for any burst that was in  
progress. The external addresses are ignored when ADV/LD is sampled high.  
R/W  
Read / Write  
Clock Enable  
I
I
N/A  
R/W signal is a synchronous input that identifies whether the current load cycle initiated is a  
Read or Write access to the memory array. The data bus activity for the current cycle takes  
place two clock cycles later.  
LOW  
Synchronous Clock Enable Input. When CEN is sampled high, all other synchronous  
inputs, including clock are ignored and outputs remain unchanged. The effect of CEN  
sampled high on the device outputs is as if the low to high clock transition did not occur.  
For normal operation, CEN must be sampled low at rising edge of clock.

On load write cycles (When R/W and ADV/LD are sampled low) the appropriate byte write  
signal (BW1-BW4) must be valid. The byte write signal must also be valid on each cycle of  
a burst write. Byte Write signals are ignored when R/W is sampled high. The appropriate  
byte(s) of data are written into the device two cycles later. BW -BW can all be tied low if  
always doing write to the entire 36-bit word.

the data bus will tri-state two clock cycles after deselect is initiated.

CLK  
N/A  
N/A  
This is the clock input to the IDT71V65603/5803. Except for OE, all timing references for the  
device are made with respect to the rising edge of CLK.  
I/O0-I/O31  
Data Input/Output  
Linear Burst Order  
I/O  
I
Synchronous data input/output (I/O) pins. Both the data input path and data output path are  
registered and triggered by the rising edge of CLK.  
I/OP1-I/OP4  
LOW  
Burst order selection input. When LBO is high the Interleaved burst sequence is selected.  
When LBO is low the Linear burst sequence is selected. LBO is a static input and it must  
not change during device operation.  
LBO

I
LOW  
N/A  
Asynchronous output enable. OE must be low to read data from the 71V65603/5803. When  
OE is high the I/O pins are in a high-impedance state. OE does not need to be actively  
controlled for read and write cycles. In normal operation, OE can be tied low.  
OE  
ZZ  
Asynchronous sleep mode input. ZZ HIGH will gate the CLK internally and power down the  
71V65603/5803 to its lowest power consumption level. Data retention is guaranteed in  
Sleep Mode.

NOTES:  
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may  
cause permanent damage to the device. This is a stress rating only and functional  
operation of the device at these or any other conditions above those indicated in the  
operational sections of this specification is not implied. Exposure to absolute  
maximum rating conditions for extended periods may affect reliability.  
2. VDD terminals only.  
3. VDDQ terminals only.  
4. Input terminals only.  
5. I/O terminals only.  
6. This is a steady-state DC parameter that applies after the power supply has  
reached its nominal operating value. Power sequencing is not necessary; however,  
the voltage on any input or I/O pin cannot exceed VDDQ during power supply ramp

NOTES:  
1. L = VIL, H = VIH, X = Don’t Care.  
2. When ADV/LD signal is sampled high, the internal burst counter is incremented. The R/W signal is ignored when the counter is advanced. Therefore the nature of the burst  
cycle (Read or Write) is determined by the status of the R/W signal when the first address is loaded at the beginning of the burst cycle.  
3. Deselect cycle is initiated when either (CE1, or CE2 is sampled high or CE2 is sampled low) and ADV/LD is sampled low at rising edge of clock. The data bus will tri-state  
two cycles after deselect is initiated.  
4. When CEN is sampled high at the rising edge of clock, that clock edge is blocked from propogating through the part. The state of all the internal registers and the I/Os remains  
unchanged.  
5. To select the chip requires CE1 = L, CE2 = L, CE2 = H on these chip enables. Chip is deselected if any one of the chip enables is false.  
6. Device Outputs are ensured to be in High-Z after the first rising edge of clock upon power-up.  
7. Q - Data read from the device, D - data written to the device.

NOTES:  
1. tF = 1/tCYC.  
2. Measured as HIGH above 0.6VDDQ and LOW below 0.4VDDQ.  
3. Transition is measured ±200mV from steady-state.  
4. These parameters are guaranteed with the AC load (Figure 1) by device characterization. They are not production tested.  
5. To avoid bus contention, the output buffers are designed such that tCHZ (device turn-off) is about 1ns faster than tCLZ (device turn-on) at a given temperature and voltage. The  
specs as shown do not imply bus contention because tCLZ is a Min. parameter that is worse case at totally different test conditions (0 deg. C, 3.465V) than tCHZ, which is a  
Max. parameter (worse case at 70 deg. C, 3.135V).  
6. Commercial temperature range only.

NOTES:  
1. D (A1) represents the first input to the external address A1. D (A2) represents the first input to the external address A2; D (A2+1) represents the next input data in the burst sequence of  
the base address A2, etc. where address bits A0 and A1 are advancing for the four word burst in the sequence defined by the state of the LBO input.  
2. CE2 timing transitions are identical but inverted to the CE1 and CE2 signals. For example, when CE1 and CE2 are LOW on this waveform, CE2 is HIGH.  
3. Burst ends when new address and control are loaded into the SRAM by sampling ADV/LD LOW.  
4. R/W is don't care when the SRAM is bursting (ADV/LD sampled HIGH). The nature of the burst access (Read or Write) is fixed by the state of the R/W signal when new address  
and control are loaded into the SRAM.  
5. Individual Byte Write signals (BWx) must be valid on all write and burst-write cycles. A write cycle is initiated when R/W signal is sampled LOW. The byte write information comes in two  
cycles before the actual data is presented to the SRAM.

NOTES:  
1. Q (A1) represents the first output from the external address A1. D (A2) represents the input data to the SRAM corresponding to address A2.  
2. CE2 timing transitions are identical but inverted to the CE1 and CE2 signals. For example, when CE1 and CE2 are LOW on this waveform, CE2 is HIGH.  
3. Individual Byte Write signals (BWx) must be valid on all write and burst-write cycles. A write cycle is initiated when R/W signal is sampled LOW. The byte write information comes in two  
cycles before the actual data is presented to the SRAM.

NOTES:  
1. Q (A1) represents the first output from the external address A1. D (A2) represents the input data to the SRAM corresponding to address A2.  
2. CE2 timing transitions are identical but inverted to the CE1 and CE2 signals. For example, when CE1 and CE2 are LOW on this waveform, CE2 is HIGH.  
3. CEN when sampled high on the rising edge of clock will block that L-H transition of the clock from propogating into the SRAM. The part will behave as if the L-H clock transition did not  
occur. All internal registers in the SRAM will retain their previous state.  
4. Individual Byte Write signals (BWx) must be valid on all write and burst-write cycles. A write cycle is initiated when R/W signal is sampled LOW. The byte write information comes in two  
cycles before the actual data is presented to the SRAM.
