The Cypress CY7C09089V-12AXI is a 512Kbit synchronous dual-port SRAM organized as 64K x 8, with a 12 ns access time and a 50 MHz clock. The part comes in a 100-TQFP (14x14) surface-mount package. This is a volatile memory with a parallel interface, intended for applications requiring simultaneous read/write access from two independent ports — common in shared-memory buffering between processors, DSPs, or FPGAs in telecom infrastructure, industrial controllers, and high-speed data acquisition.
No factory orders are accepted; the part is available only through the surplus and broker channel.
Design-in note: synchronous dual-port architecture
The synchronous interface means all address, data, and control signals are registered on the rising edge of the clock, simplifying timing closure in high-speed designs. The 12 ns access time at 50 MHz clock gives a bus turnaround margin that suits back-to-back read/write cycles without wait states. Supply decoupling should follow the standard 0.1 µF per VDD pin plus a bulk 10 µF near the package; the 100-TQFP has a 0.5 mm pitch, so fine-pitch soldering and X-ray inspection are recommended for production.
