576Kbit dual-port SRAM — 15 ns asynchronous access
The CY7C037V-15AXC is a 576Kbit dual-port asynchronous SRAM organized 32K x 18, offering simultaneous independent access from two ports without arbitration logic on the memory array itself. Access time is 15 ns, and the write cycle time matches at 15 ns for word or page operations — this sets the bus turnaround floor for a shared-memory interface between two controllers or a controller and an FPGA. Supply voltage spans 3V to 3.6V, with a commercial temperature range of 0°C to 70°C — suitable for indoor equipment, test gear, and telecom line cards where ambient stays within a conditioned environment.
What the 15 ns access time means for your bus design
15 ns access time means the data appears on the output bus within 15 ns of the address being valid — the memory controller must hold the address stable for that window plus any hold time after chip enable or output enable asserts. The 15 ns write cycle time (word or page) indicates the minimum pulse width for a write operation — shorter pulses risk incomplete data capture. Both ports run independently at this speed, so the arbitration logic (if any) is external.
