Obsolete — sourcing a last-time-buy or surplus lot
The CY7C09349AV-12AC carries an official Obsolete product status. The only supply channel is independent distribution — surplus, new-old-stock, or broker-sourced lots.
This is a Cypress synchronous dual-port SRAM organised as 4K x 18 bits. The 12 ns access time and 50 MHz clock rate let two independent bus masters — two processors, a processor and an FPGA, or a processor and a DMA controller — read and write the same memory array without dead cycles. The 18-bit word width suits designs that carry a parity bit per byte or a ninth tag bit alongside the 16-bit data.
Supplied in a 100-pin TQFP (14x14 mm body) for surface-mount assembly. Supply voltage range is 3.0 V to 3.6 V, compatible with 3.3 V nominal rails.
