The Cypress CY7C037V-15AXCT is a 576Kbit asynchronous dual-port SRAM organized as 32K×18. It operates from a 3.3V supply and delivers a 15 ns access time over a parallel interface. The dual-port architecture allows two independent systems or processors to read from and write to the same memory array without a shared bus — each port has its own address, data, and control lines. Typical applications include shared-message mailboxes in multi-processor industrial controllers, data buffers in telecom line cards, and FIFO replacement where true random access is needed. The part is housed in a 100-LQFP (14×14 mm TQFP) and rated for 0°C to 70°C commercial temperature range.
Access time is 15 ns from address valid. Write cycle time is also 15 ns.
