CY7C199-15VC

CY7C199-15VC is Cypress’ dual-port static RAM (DPRAM). Key idea: two independent memory ports (Port A and Port B) with separate address and data paths, allowing concurrent reads/writes and making it ideal for fast buffering between processors or peripherals.
Key points:
- Dual-port SRAM: enables simultaneous access from two masters.
- Asynchronous operation: no wait states; straightforward timing.
- 15 ns access time (the “-15” speed grade).
- Typically 5V operation (voltage Family details vary by package); “VC” denotes package/voltage family options (consult datasheet for exact options).
- Available in various organizations and package types (e.g., SOIC/PLCC variants); exact density and bus width depend on the specific device variant.
- Common uses: inter-CPU buffers, high-speed FIFOs, crossbar/shared-memory applications.
For exact capacity, pinout, and electrical characteristics, refer to the CY7C199-15VC datasheet and the specific package you plan to use.

CY7C199-15VC is a high-speed CMOS static RAM. Key features include:
- 1 Mbit memory (128K × 8) organization
- 15 ns access time
- 5 V operation (typical 4.5–5.5 V)
- Asynchronous operation with control pins: CE#, OE#, WE#
- True 3-state I/O for bus sharing
