SSR005-0A 02/02/2004 1 IC61LV6432 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 • 3.3V VCC and 2.5V VCCQ for I/O's • 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 IC61LV6432 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 IC61LV6432 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.

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.

Tested with load in Figure 2. 5. The assertion of ZZ allows the SRAM to enter a lower power state than when deselected within the time specified. Data retention is guaranteed when ZZ is asserted and clock remains active. 6. ADSC and ADSP must not be asserted for at least two cycles after leaving ZZ state. Integrated Circuit Solution Inc.
