Description and Introduction

262144-BIT (32768-WORD BY 8-BIT) CMOS STATIC RAM The part **M5M5256CFP-12VXL** is a **256K × 16-bit (4M-bit) CMOS pseudostatic RAM (PSRAM)** manufactured by **Mitsubishi Electric (MIT)**.  

### **Key Specifications:**  
- **Organization:** 256K × 16-bit  
- **Density:** 4M-bit  
- **Technology:** CMOS PSRAM (Pseudostatic RAM)  
- **Voltage Supply:** **5V ± 10%**  
- **Access Time:** **12ns** (as indicated by "-12" in the part number)  
- **Package:** **FP (Plastic Flat Package, likely 52-pin PLCC or similar)**  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) – exact range depends on suffix  

### **Features:**  
- **Pseudostatic operation** – No external refresh required (internally refreshed)  
- **Fully static operation** – No clock or refresh needed  
- **Low power consumption** (standby and active modes)  
- **TTL-compatible inputs and outputs**  
- **Single 5V power supply**  
- **High-speed access time (12ns)**  

### **Applications:**  
- Embedded systems  
- Networking equipment  
- Industrial controls  
- Telecommunications

Alternative Part Number

  • IS62C256AL-12TLI --: 32K x 8 asynchronous SRAM with 120 ns access time, functionally equivalent to the M5M5256C and widely available from a different vendor.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM in a similar package with compatible pinout; faster 70 ns speed grade can replace the 120 ns part.
  • AS6C62256-55PCN --: Direct 32K x 8 SRAM replacement series often used to substitute Mitsubishi M5M5256 devices, with 55 ns access time and 5V operation.
