概述
Description
The M4A5-128/64-10VNC is a 128K x 64-bit (1MB) asynchronous dual-port SRAM from Cypress Semiconductor (now Infineon). It features:
- Dual independent ports for simultaneous read/write access.
- 10ns access time, suitable for high-speed applications.
- Asynchronous operation (no clock required).
- 3.3V power supply (VNC = 3.3V tolerant).
- Bus arbitration to prevent data corruption during simultaneous writes.
Commonly used in networking, telecom, and multiprocessor systems where shared memory access is needed. The -10VNC suffix indicates speed grade (10ns) and voltage tolerance.
