The Infineon CY7C09369V-6AXC is a 288Kbit synchronous dual-port SRAM organized as 16K x 18, with a 6.5 ns access time and a 100 MHz clock. The 18-bit word width is the key differentiator here: the extra two bits per word let you carry a parity or ECC check bit alongside the 16-bit data path, which is exactly what you want in a shared-memory buffer where data integrity matters — think base-station line cards, video frame buffers, or multiprocessor mailboxes. The 6.5 ns access time means the part can keep up with a 100 MHz bus without inserting wait states, provided the controller's output hold time and the PCB trace delay budget are within a couple of nanoseconds.
Obsolete — no official replacement on record
The CY7C09369V-6AXC is Obsolete. No official successor is listed. A replacement would need to match the 16K x 18 organization, 6.5 ns access time, 100 MHz clock, 3V~3.6V supply, and 100-LQFP footprint.
100-TQFP footprint and commercial temperature grade
The part comes in a 100-LQFP package, surface-mount, supplied in Tray. It is intended for indoor, temperature-controlled environments.
