80960Jx Overview
The 80960Jx processor offers high performance to cost-sensitive 32-bit embedded applications.
The 80960Jx is object code compatible with the 80960 core architecture and is capable of sustained
execution at the rate of one instruction per clock. This processor’s features include generous
instruction cache, data cache, and data RAM. It also boasts a fast interrupt mechanism and
dual-programmable timer units.
The 80960Jx processor’s clock multiplication operates the processor core at two or three times the
bus clock rate to improve execution performance without increasing the complexity of board
designs.
Memory subsystems for cost-sensitive embedded applications often impose substantial wait state
penalties. The 80960Jx integrates considerable storage resources on-chip to decouple CPU
execution from the external bus.
The 80960Jx rapidly allocates and de-allocates local register sets during context switches. The
processor must flush a register set to the stack only when it saves more than seven sets to its local
register cache.
A 32-bit multiplexed burst bus provides a high-speed interface to system memory and I/O. A full
complement of control signals simplifies the connection of the 80960Jx to external components.
The user programs physical and logical memory attributes through memory-mapped control
registers (MMRs), an extension not found on the i960® Kx, Sx or Cx processors. Physical and
logical configuration registers enable the processor to operate with all combinations of bus width
and data object alignment. The processor supports a homogeneous byte ordering model.
This processor integrates two important peripherals: a timer unit and an interrupt controller. These
and other hardware resources are programmed through memory-mapped control registers, an
extension to the familiar i960 processor architecture.
The timer unit (TU) offers two independent 32-bit timers for use as real-time system clocks and
general-purpose system timing. These operate in either single-shot or auto-reload mode and may
generate interrupts.
The interrupt controller unit (ICU) provides a flexible, low-latency means for requesting interrupts.
The ICU provides full programmability of up to 240 interrupt sources into 31 priority levels. The
ICU takes advantage of a cached priority table and optional routine caching to minimize interrupt
latency. Clock doubling on the 80960JD/JC processors reduces interrupt latency by 40% compared
to the 80960JA/JF, and clock tripling on the 80960JT reduces interrupt latency by 20% compared
to the 80960JD/JC. Local registers may be dedicated to high-priority interrupts to further reduce
latency. Acting independently from the core, the ICU compares the priorities of posted interrupts
with the current process priority, off-loading this task from the core. The ICU also supports the
integrated timer interrupts.
The 80960Jx features a Halt mode designed to support applications where low power consumption
is critical. The halt instruction shuts down instruction execution, resulting in a power savings of up
to 90 percent.
The 80960Jx’s testability features, including ONCE (On-Circuit Emulation) mode and Boundary
Scan (JTAG), provide a powerful environment for design debug and fault diagnosis.

80960 Processor Core
The 80960Jx family is a scalar implementation of the 80960 core architecture. Intel designed this
processor core as a very high performance device that is also cost-effective. Factors that contribute
to the core’s performance include:
• Core operates at the bus speed with the 80960JA/JF/JS
• Core operates at two or three times the bus speed with the 80960JD/JC and 80960JT,
respectively
• Single-clock execution of most instructions
• Independent Multiply/Divide Unit
• Efficient instruction pipeline minimizes pipeline break latency
• Register and resource scoreboarding allow overlapped instruction execution
• 128-bit register bus speeds local register caching
• Two-way set associative, integrated instruction cache
• Direct-mapped, integrated data cache
• 1-Kbyte integrated data RAM delivers zero wait state program data

2.2
Burst Bus
A 32-bit high-performance Bus Controller Unit (BCU) interfaces the 80960Jx to external memory
and peripherals. The BCU fetches instructions and transfers data at the rate of up to four 32-bit
words per six clock cycles. The external address/data bus is multiplexed.
Users may configure the 80960Jx’s bus controller to match an application’s fundamental memory
organization. Physical bus width is register-programmed for up to eight regions. Byte ordering and
data caching are programmed through a group of logical memory templates and a defaults register.
The BCU’s features include:
• Multiplexed external bus to minimize pin count
• 32-, 16-, and 8-bit bus widths to simplify I/O interfaces
• External ready control for address-to-data, data-to-data and data-to-next-address wait state
types
• Support for big or little endian byte ordering to facilitate the porting of existing program code
• Unaligned bus accesses performed transparently
• Three-deep load/store queue to decouple the bus from the core
Upon reset, the 80960Jx conducts an internal self-test. Then, before executing its first instruction, it
performs an external bus confidence test by performing a checksum on the first words of the
initialization boot record (IBR).
2.3
2.4
Timer Unit
The timer unit (TU) contains two independent 32-bit timers that are capable of counting at several
clock rates and generating interrupts. Each is programmed by use of the TU registers. These
memory-mapped registers are addressable on 32-bit boundaries. The timers have a single-shot
mode and auto-reload capabilities for continuous operation. Each timer has an independent
interrupt request to the 80960Jx’s interrupt controller. The TU may generate a fault when
unauthorized writes from user mode are detected. Clock prescaling is supported.
Priority Interrupt Controller
A programmable interrupt controller manages up to 240 external sources through an 8-bit external
interrupt port. Alternatively, the interrupt inputs may be configured for individual edge- or level-
triggered inputs. The interrupt unit (IU) also accepts interrupts from the two on-chip timer channels
and a single Non-Maskable Interrupt (NMI#) pin. Interrupts are serviced according to their priority
levels relative to the current process priority.
Low interrupt latency is critical to many embedded applications. As part of its highly flexible
interrupt mechanism, the 80960Jx exploits several techniques to minimize latency:
• Interrupt vectors and interrupt handler routines may be reserved on-chip.
• Register frames for high-priority interrupt handlers may be cached on-chip.
• The interrupt stack may be placed in cacheable memory space.
• Interrupt microcode executes at two or three times the bus frequency for the 80960JD/JC and
80960JT, respectively.

Instruction Set Summary
The 80960Jx adds several new instructions to the i960 processor core architecture. The new
instructions are:
• Conditional Move
• Conditional Add
• Conditional Subtract
• Byte Swap
• Halt
• Cache Control
• Interrupt Control
Table 2 identifies the instructions that the 80960Jx supports. Refer to the i960® Jx Microprocessor
Developer’s Manual (272483) for a detailed description of each instruction.
2.6
2.7
Faults and Debugging
The 80960Jx employs a comprehensive fault model. The processor responds to faults by making
implicit calls to a fault handling routine. Specific information collected for each fault allows the
fault handler to diagnose exceptions and recover appropriately.
The processor also has built-in debug capabilities. In software, the 80960Jx may be configured to
detect as many as seven different trace event types. Alternatively, mark and fmark instructions
may generate trace events explicitly in the instruction stream. Hardware breakpoint registers are
also available to trap on execution and data addresses.
Low Power Operation
Intel fabricates the 80960Jx using an advanced sub-micron manufacturing process. The processor’s
sub-micron topology provides the circuit density for optimal cache size and high operating speeds
while dissipating modest power. The processor also uses dynamic power management to turn off
clocks to unused circuits.
Users may program the 80960Jx to enter Halt mode for maximum power savings. In Halt mode,
the processor core stops completely while the integrated peripherals continue to function, reducing
overall power requirements up to 90 percent. Processor execution resumes from internally or
externally generated interrupts.
2.8
Test Features
The 80960Jx incorporates numerous features that enhance the user’s ability to test both the
processor and the system to which it is attached. These features include ONCE (On-Circuit
Emulation) mode and Boundary Scan (JTAG).
12
Datasheet
80960JA/JF/JD/JS/JC/JT 3.3 V Embedded 32-Bit Microprocessor
The 80960Jx provides testability features compatible with IEEE Standard Test Access Port and
Boundary Scan Architecture (IEEE Std. 1149.1).
One of the boundary scan instructions, HIGHZ, forces the processor to float all its output pins
(ONCE mode). ONCE mode may also be initiated at reset without using the boundary scan
mechanism.
ONCE mode is useful for board-level testing. This feature allows a mounted 80960Jx to
electrically “remove” itself from a circuit board. This allows for system-level testing in which a
remote tester, such as an in-circuit emulator, may exercise the processor system.
The provided test logic does not interfere with component or circuit board behavior and ensures
that components function correctly, connections between various components are correct, and
various components interact correctly on the printed circuit board.
The JTAG Boundary Scan feature is an attractive alternative to conventional “bed-of-nails” testing.
It may examine connections that might otherwise be inaccessible to a test system.
2.9
Memory-Mapped Control Registers
The 80960Jx, although compliant with the i960 processor core, has the added advantage of
memory-mapped, internal control registers not found on the i960 Kx, Sx or Cx processors. These
registers give software the interface to easily read and modify internal control registers.
Each of these registers is accessed as a memory-mapped, 32-bit register. Access is accomplished
through regular memory-format instructions. The processor ensures that these accesses do not
generate external bus cycles.
2.10
Data Types and Memory Addressing Modes
As with all i960 processors, the 80960Jx instruction set supports several data types and formats:
• Bit
• Bit fields
• Integer (8-, 16-, 32-, 64-bit)
• Ordinal (8-, 16-, 32-, 64-bit unsigned integers)
• Triple word (96 bits)
• Quad word (128 bits)
The 80960Jx provides a full set of addressing modes for C and assembly programming:
• Two Absolute modes
• Five Register Indirect modes
• Index with displacement
• IP with displacement

DESCRIPTION
ADDRESS / DATA BUS carries 32-bit physical addresses and 8-, 16- or 32-bit data
to and from memory. During an address (T ) cycle, bits 31:2 contain a physical word
address (bits 0-1 indicate SIZE; see belowa). During a data (Td) cycle, read or write
data is present on one or more contiguous bytes, comprising AD[31:24], AD[23:16],
AD[15:8] and AD[7:0]. During write operations, unused pins are driven to
determinate values.
SIZE, which comprises bits 0-1 of the AD lines during a T cycle, specifies the
a
number of data transfers during the bus transaction.

When the processor enters Halt mode, if the previous bus operation was a:
•

write — AD[31:2] are driven with the last data value on the AD bus.
read — AD[31:4] are driven with the last address value on the AD bus; AD[3:2]

Typically, AD[1:0] reflect the SIZE information of the last bus transaction (either
instruction fetch or load/store) that was executed before entering Halt mode.

BE2# enables data on AD[23:16]
BE1# enables data on AD[15:8]
BE0# enables data on AD[7:0]

The processor asserts byte enables, byte high enable and byte low enable during
T .

Since unaligned bus requests are split into separate bus transactions, these signals
do not toggle during a burst. They remain active through the last Td cycle.
For accesses to 8- and 16-bit memory, the processor asserts the address bits in
conjunction with A[3:2] described above.

next cycle by inserting a wait state (Tw).
0 = sample data
1 = don’t sample data
I
RDYRCV#

The RDYRCV# pin has another function during the recovery (Tr) state. The
processor continues to insert additional recovery states until it samples the pin
HIGH. This function gives slow external devices more time to float their buffers
before the processor begins to drive address again.
0 = insert wait states
1 = recovery complete
BUS LOCK indicates that an atomic read-modify-write operation is in progress. The
LOCK# output is asserted in the first clock of an atomic operation and deasserted in
the last data transfer of the sequence. The processor does not grant HOLDA while it
is asserting LOCK#. This prevents external agents from accessing memory involved
in semaphore operations.

mode, the processor stops all clocks and floats all output pins. The pin has a weak
internal pullup which is active during reset to ensure normal operation when the pin
is left unconnected.
0 = ONCE mode enabled
1 = ONCE mode not enabled
HOLD: A request from an external bus master to acquire the bus. When the
processor receives HOLD and grants bus control to another master, it asserts
HOLDA, floats the address/data and control lines and enters the Th state. When

core and the external bus run at the CLKIN rate. All input and output timings are
specified relative to a rising CLKIN edge.
CLKIN
I
RESET initializes the processor and clears its internal logic. During reset, the
processor places the address/data bus and control output pins in their idle (inactive)

During reset, the input pins are ignored with the exception of LOCK#/ONCE#,
STEST and HOLD.
I
RESET#
A(L)
The RESET# pin has an internal synchronizer. To ensure predictable processor
initialization during power up, RESET# must be asserted a minimum of 10,000
CLKIN cycles with VCC and CLKIN stable. On a warm reset, RESET# should be
asserted for a minimum of 15 cycles.
SELF TEST enables or disables the processor’s internal self-test feature at
initialization. STEST is examined at the end of reset. When STEST is asserted, the
processor performs its internal self-test and the external bus confidence test. When
STEST is deasserted, the processor performs only the external bus confidence test.

TEST CLOCK is a CPU input which provides the clocking function for IEEE 1149.1
Boundary Scan Testing (JTAG). State information and data are clocked into the
processor on the rising edge; data is clocked out of the processor on the falling edge.

TEST DATA OUTPUT is the serial output pin for JTAG. TDO is driven on the falling
edge of TCK during the SHIFT-IR and SHIFT-DR states of the Test Access Port. At
other times, TDO floats. TDO does not float during ONCE mode.

TEST RESET asynchronously resets the Test Access Port (TAP) controller function
of IEEE 1149.1 Boundary Scan testing (JTAG). When using the Boundary Scan
feature, connect a pull-down resistor between this pin and VSS. When TAP is not
used, this pin must be connected to VSS; however, no resistor is required. See
Section 4.3, “Connection Recommendations” on page 36.

POWER pins intended for external connection to a VCC board plane.
PLL POWER is a separate VCC supply pin for the phase lock loop clock generator. It
is intended for external connection to the VCC board plane. In noisy environments,
add a simple bypass filter circuit to reduce noise-induced clock jitter and its effects on
timing relationships.

5 V REFERENCE VOLTAGE input is the reference voltage for the 5 V-tolerant I/O
buffers. This signal should be connected to +5 V for use with inputs which exceed
3.3 V. When all inputs are from 3.3 V components, this pin should be connected to
3.3 V.

Table 10. Pin Description—Interrupt Unit Signals
NAME
TYPE
DESCRIPTION
EXTERNAL INTERRUPT pins are used to request interrupt service. The XINT[7:0]#
pins may be configured in three modes:
Dedicated Mode: Each pin is assigned a dedicated interrupt level. Dedicated inputs
may be programmed to be level (low) or edge (falling) sensitive.
I
Expanded Mode: All eight pins act as a vectored interrupt source. The interrupt pins
are level sensitive in this mode.
XINT[7:0]#
A(E/L)
Mixed Mode: The XINT[7:5]# pins act as dedicated sources and the XINT[4:0]# pins
act as the five most significant bits of a vectored source. The least significant bits of
the vectored source are set to 0102 internally.
Unused external interrupt pins should be connected to VCC
.
NON-MASKABLE INTERRUPT causes a non-maskable interrupt event to occur.
NMI# is the highest priority interrupt source and is falling edge-triggered. when NMI#
I
NMI#
A(E)
is unused, it should be connected to VCC
.

Connection Recommendations
For clean on-chip power distribution, V and V pins separately feed the device’s functional
CC
SS
units. Power and ground connections must be made to all 80960Jx power and ground pins. On the
circuit board, every V pin should connect to a power plane and every V pin should connect to
CC
SS
a ground plane. Place liberal decoupling capacitance near the 80960Jx, since the processor may
cause transient power surges.
The 80960JS/JC/JT processors are produced on Intel’s advanced CMOS process. Proper bulk
decoupling must be used to prevent device damage during initial power up and during transitions
from low power mode to normal processor operation. Power supply behavior during these
transitions may cause the power supply to exceed the maximum V specification and may cause
CC
device damage.
Pay special attention to the Test Reset (TRST#) pin. It is essential that the JTAG Boundary Scan
Test Access Port (TAP) controller initializes to a known state whether it may be used or not. When
the JTAG Boundary Scan function may be used, connect a pull-down resistor between the TRST#
pin and V . When the JTAG Boundary Scan function may not be used (even for board-level
SS
testing), connect the TRST# pin to V
.
SS
Do not connect the TDI, TDO, and TCK pins when the TAP Controller may not be used.
Pins identified as NC must not be connected in the system.

VCC5 Pin Requirements (VDIFF)
In 3.3 V only systems where the 80960Jx input pins are driven from 3.3 V logic, connect the VCC5
pin directly to the 3.3 V V plane.
CC
In mixed voltage systems where the processor is powered by 3.3 V and interfaces with 5 V
components, VCC5 must be connected to 5 V. This allows proper 5 V tolerant buffer operation, and
prevents damage to the input pins. The voltage differential between the 80960Jx VCC5 pin and its
3.3 V V pins must not exceed 2.25 V. When this requirement is not met, current flow through the
CC
pin may exceed the value at which the processor is damaged. Instances when the voltage may
exceed 2.25 V is during power up or power down, where one source reaches its level faster than the
other, briefly causing an excess voltage differential. Another instance is during steady-state
operation, where the differential voltage of the regulator (provided a regulator is used) cannot be
maintained within 2.25 V. Two methods are possible to prevent this from happening:
• Use a regulator that is designed to prevent the voltage differential from exceeding 2.25 V.
or:
• As shown in Figure 8, place a 100 Ω resistor in series with the VCC5 pin to limit the current
through VCC5.

When the regulator cannot prevent the 2.25 V differential, the addition of the resistor is a simple
and reliable method for limiting current. The resistor may also prevent damage in the case of a
power failure, where the 5 V supply remains on and the 3.3 V supply goes to zero.

VCCPLL Pin Requirements
To reduce clock skew on the 80960Jx processor, the VCCPLL pin for the Phase Lock Loop (PLL)
circuit is isolated on the pinout. The lowpass filter, as shown in Figure 9, reduces noise induced
clock jitter and its effects on timing relationships in system designs. The 4.7
low ESR solid tantalum; the 0.01 F capacitor must be of the type X7R and the node connecting
VCCPLL must be as short as possible.
µF capacitor must be
µ
When the voltage on the VCCPLL power supply pin exceeds the V pin voltage by 0.5 V at any
CC
time, including the power up and power down sequences, excessive currents may permanently
damage on-chip electrostatic discharge (ESD) protection diodes. The damage may accumulate over
multiple episodes.
In actual applications, this problem occurs only when the VCCPLL and V pins are driven by
CC
separate power supplies or voltage regulators. Applications that use one power supply for
VCCPLL and V are not typically at risk. Verify that your application does not allow the
CC
VCCPLL voltage to exceed V by 0.5 V.
CC
The VCCPLL low-pass filter recommendation does not promote this problem.

NOTES:
1. Not tested.
2. To ensure a 1:1 relationship between the amplitude of the input jitter and the internal clock, the jitter
frequency spectrum should not have any power peaking between 500 KHz and 1/3 of the CLKIN
frequency.
3. Inactive ALE/ALE# refers to the falling edge of ALE and the rising edge of ALE#. For inactive ALE/ALE#
timings, refer to Relative Output Timings in this table.
4. A float condition occurs when the output current becomes less than I . Float delay is not tested, but is
OL
designed to be no longer than the valid delay.
5. AD[31:0] are synchronous inputs. Setup and hold times must be met for proper processor operation. NMI#
and XINT[7:0]# may be synchronous or asynchronous. Meeting setup and hold time guarantees
recognition at a particular clock edge. For asynchronous operation, NMI# and XINT[7:0]# must be asserted
for a minimum of two CLKIN periods to ensure recognition.
6. RDYRCV# and HOLD are synchronous inputs. Setup and hold times must be met for proper processor
operation.
7. RESET# may be synchronous or asynchronous. Meeting setup and hold time guarantees recognition at a
particular clock edge.
8. ONCE# and STEST# must be stable at the rising edge of RESET# for proper operation.
9. Guaranteed by design. May not be 100% tested.
10.Relative to falling edge of TCK.
11.Worst-case TOV condition occurs on I/O pins when pins transition from a floating high input to driving a low
output state. The Address/Data Bus pins encounter this condition between the last access of a read, and
the address cycle of a following write. 5 V signals take 3 ns longer to discharge than 3.3 V signals at 50 pF
loads.

Device Identification
80960Jx processors may be identified electrically, according to device type and stepping (see
Figure 39, and Table 25 through Table 30). Table 24 identifies the device type and stepping
for all 5 V, 80960Jx processors. Figure 39, and Table 25 through Table 30 identify all 3.3 V
to 5 V-tolerant 80960Jx processors. The device ID was enhanced to differentiate between 3.3 V and
5 V supply voltages, and between non-clock-doubled and clock-doubled cores when stepping from
the A2 stepping to the C0 stepping. The 32-bit identifier is accessible in several ways:
• Upon reset, the identifier is placed into the g0 register.
• The identifier may be accessed from supervisor mode at any time by reading the DEVICEID
register at address FF008710H.
• The IEEE Standard 1149.1 Test Access Port may select the DEVICE ID register through the
IDCODE instruction.
• The device and stepping letter is also printed on the top side of the product package.

Thermal Specifications
The 80960Jx is specified for operation when T (case temperature) is within the range of 0° C to
C
100° C for PGA, MPBGA and PQFP packages. Extended temperature devices are also available in
a PQFP package and an MPBGA package with T = -40° C to 100° C. Case temperature may be
C
measured in any environment to determine whether the 80960Jx is within its specified operating
range. The case temperature should be measured at the center of the top surface, opposite the pins.
θ
is the thermal resistance from case to ambient. Use the following equation to calculate T , the
A
maximum ambient temperature to conform to a particular case temperature:
CA
T = T - P
(
θ
)

Junction temperature (T ) is commonly used in reliability calculations. T may be calculated from

Similarly, when T is known, the corresponding case temperature (T ) may be calculated as

Notes:
1. The processor asserts FAIL# during built-in self-test. When self- test passes, the FAIL# pin is deasserted.The processor also asserts FAIL#
during the bus confidence test. When the bus confidence test passes, FAIL# is deasserted and the processor begins user program execution.
2. If the processor fails built-in self-test, it initiates one dummy load bus access. The load address indicates the point of self-test failure.
3. Since the bus is idle, hold requests are honored during reset and built-in self-test.
4. When selected, built-in self test requires approximately (in CLKIN periods): 393,000 for 80960JT, 580,012 for the 80960JC,

7.1
Basic Bus States
The bus has five basic bus states: idle (Ti), address (Ta), wait/data (Tw/Td), recovery (Tr), and hold
(Th). During system operation, the processor continuously enters and exits different bus states.
Figure 52 shows the five bus states.
The bus occupies the idle (Ti) state when no address/data transactions are in progress and when
RESET# is asserted. When the processor needs to initiate a bus access, it enters the Ta state to
transmit the address.
Following a Ta state, the bus enters the Tw/Td state to transmit or receive data on the address/data
lines. Assertion of the RDYRCV# input signal indicates completion of each transfer. When data is
not ready, the processor may wait as long as necessary for the memory or I/O device to respond.
After the data transfer, the bus exits the Tw/Td state and enters the recovery (Tr) state. In the case
of a burst transaction, the bus exits the Td state and re-enters the Td/Tw state to transfer the next
data word. The processor asserts the BLAST# signal during the last Tw/Td states of an access.
Once all data words transfer in a burst access (up to four), the bus enters the Tr state to allow
devices on the bus to recover.
The processor remains in the Tr state until RDYRCV# is deasserted. When the recovery state
completes, the bus enters the Ti state when no new accesses are required. When an access is
pending, the bus enters the Ta state to transmit the new address.

Boundary-Scan Register
The Boundary-Scan register contains a cell for each pin as well as cells for control of I/O and
HIGHZ pins.
Table 42 shows the bit order of the 80960Jx processor Boundary-Scan register. All table cells that
contain ‘CTL’ select the direction of bidirectional pins or HIGHZ output pins. When a 1 is loaded
into the control cell, the associated pin(s) are HIGHZ or selected as input.
