The Cypress CY7C1021CV33-12ZSXET is a 1Mbit (64K x 16) asynchronous SRAM organized as 64K words of 16 bits each, with a 12 ns access time that lets it interface directly with moderate-speed processors and DSPs without inserting wait states on a 50–66 MHz bus. The parallel interface and 3.0–3.6 V supply make it a drop-in fit for legacy 3.3 V memory buses in industrial controllers, telecom line cards, and embedded systems that need fast scratchpad or packet buffer memory.
