SRAM Chip Sync Quad 2.5V/3.3V 2M-Bit 64K x 32 4ns 100-Pin TQFP

The IS61LP6432A is a high-speed synchronous static RAM designed to provide a burstable, high-performance memory for high speed networking and communication applications. The IS61LP6432A is organized as 64K words by 32 bits Fabricated advanced CMOS technology, the device integrates a 2-bit burst counter, highspeed 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 DQa, BW2\ controls DQb, BW3\ controls DQc, BW4\ controls DQd, 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 and controlled by the ADV\ (burst address advance) input pin. The mode pin is used to select the burst sequence order, Linear burst is achieved when this pin is tied LOW. Interleave burst is achieved when this pin is tied HIGH or left floating.
