IC61S6432
64K x 32 SYNCHRONOUS
PIPELINE STATIC RAM
FEATURES
DESCRIPTION
• Internal self-timed write cycle
• Individual Byte Write Control and Global Write
• Clock controlled, registered address, data and
control
• Pentium™ or linear burst sequence control using
MODE input
• Three chip enables for simple depth expansion
and address pipelining
• Common data inputs and data outputs
• Power-down control by ZZ input
• JEDEC 100-Pin LQFP and PQFP package
• Single +3.3V power supply
• Two Clock enables and one Clock disable to
eliminate multiple bank bus contention
• Control pins mode upon power-up:
– MODE in interleave burst mode
– ZZ in normal operation mode
These control pins can be connected to GNDQ
or VCCQ to alter their power-up state
• Industrial temperature available
The ICSI IC61S6432 is a high-speed, low-power synchronous
static RAM designed to provide a burstable, high-performance,
secondary cache for the Pentium™, 680X0™, and PowerPC™
microprocessors. It is organized as 65,536 words by 32 bits,
fabricated with ICSI's advanced CMOS technology. The
device integrates a 2-bit burst counter, high-speed SRAM
core, and high-drive capability outputs into a single monolithic
circuit. All synchronous inputs pass through registers
controlled by a positive-edge-triggered single clock input.
Write cycles are internally self-timed and are initiated by the
rising edge of the clock input. Write cycles can be from one
to four bytes wide as controlled by the write control inputs.
Separate byte enables allow individual bytes to be written.
BW1 controls DQ1-DQ8, BW2 controls DQ9-DQ16, BW3
controls DQ17-DQ24, BW4 controls DQ25-DQ32,
conditioned by BWE being LOW. A LOW on GW input would
cause all bytes to be written.
Bursts can be initiated with either ADSP (Address Status
Processor) or ADSC (Address Status Cache Controller)
input pins. Subsequent burst addresses can be generated
internally by the IC61S6432 and controlled by the ADV (burst
address advance) input pin.
Asynchronous signals include output enable (OE), sleep
mode input (ZZ), clock (CLK) and burst mode input (MODE).
A HIGH input on the ZZ pin puts the SRAM in the powerdown state. When ZZ is pulled LOW (or no connect), the
SRAM normally operates after three cycles of the wake-up
period. A LOW input, i.e., GNDQ, on MODE pin selects
LINEAR Burst. A VCCQ (or no connect) on MODE pin selects
INTERLEAVED Burst.

Notes:
1. All inputs except OE must meet setup and hold times for the Low-to-High transition of clock (CLK).
2. Wait states are inserted by suspending burst.
3. "X" means don't care. WRITE=L means any one or more byte write enable signals (BW1-BW4) and BWE are LOW or GW is
LOW. WRITE=H means all byte write enable signals are HIGH.
4. For a Write operation following a Read operation, OE must be HIGH before the input data required setup time and held
HIGH throughout the input data hold time.
5. ADSP LOW always initiates an internal READ at the Low-to-High edge of clock. A WRITE is performed by setting one or
more byte write enable signals and BWE LOW or GW LOW for the subsequent L-H edge of clock.

Notes:
1. Stress 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. This device contains circuity to protect the inputs against damage due to high static voltages or electric fields; however,
precautions may be taken to avoid application of any voltage higher than maximum rated voltages to this high-impedance circuit.
3. This device contains circuitry that will ensure the output devices are in High-Z at power up.
