144 Kbit dual-port SRAM — 15 ns asynchronous arbitration
The Cypress CY7C016A-15AXC is a 144 Kbit dual-port asynchronous SRAM organized as 16K x 9 bits. The dual-port architecture gives two independent bus masters simultaneous read/write access to the same memory array through separate address, data, and control ports, with on-chip arbitration logic to resolve simultaneous writes to the same address. The 9-bit width — 8 data bits plus a ninth bit often used as a parity or flag bit — suits applications like shared mailbox registers, small FIFO buffers, or inter-processor communication buffers where the ninth bit carries a semaphore or error-checking signal.
5 V supply, commercial temperature — legacy system fit
The write cycle time matches the read access time at 15 ns, so the bus timing is symmetric for read and write operations.

80-TQFP — surface-mount footprint for shared-memory placement
The package is an 80-lead TQFP with a 14 mm x 14 mm body. This is a standard fine-pitch surface-mount package, suitable for automated assembly. The footprint is compact enough to place near the two bus masters it serves, keeping trace lengths short for the parallel address and data buses — important for signal integrity at 15 ns cycle times.
