Additional Details

The CY7C199-55VC is organized as 32K x 8 bits (32768 words by 8 bits). It typically operates on a single 5V power supply. It supports asynchronous read and write operations. Consult the datasheet for detailed timing diagrams, power consumption specifications, and operating temperature ranges. Proper decoupling capacitors should be used near the power supply pins to minimize noise and ensure stable operation. This SRAM is suitable for applications needing a balance of speed and power efficiency.
