Description
The M5M5256DFP-70LL is a 256Kb (32K × 8-bit) static RAM (SRAM) chip manufactured by Mitsubishi Electric. Key features include:
- 70ns access time (fast read/write operations).
- Low-power CMOS technology, suitable for battery-backed applications.
- 5V single power supply (TTL-compatible).
- 28-pin DIP (Dual In-line Package) for easy integration.
- Wide operating temperature range (typically 0°C to 70°C).
Commonly used in embedded systems, industrial controls, and legacy computing, it provides reliable, non-volatile data storage when paired with a backup battery.
For detailed specs, refer to the datasheet from Mitsubishi (now part of Renesas).
