Description and Introduction

262144-BIT (32768-WORD BY 8-BIT) CMOS STATIC RAM The M5M5256DP-70LL is a static RAM (SRAM) manufactured by MITSUMI. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Static RAM (SRAM)  
- **Organization:** 32K x 8 bits (256K-bit)  
- **Access Time:** 70 ns  
- **Operating Voltage:** 5V ±10%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package Type:** 28-pin DIP (Dual In-line Package)  
- **Pin Count:** 28  
- **Technology:** CMOS  

### **Descriptions:**
- The M5M5256DP-70LL is a low-power CMOS static RAM with a 32K x 8-bit organization.  
- It is designed for applications requiring moderate-speed, battery-backed, or power-sensitive memory.  
- The device operates with a single 5V power supply and is compatible with TTL levels.  

### **Features:**
- **Low Power Consumption:** CMOS technology ensures reduced power usage.  
- **Battery Backup Capability:** Suitable for battery-operated applications.  
- **Fully Static Operation:** No clock or refresh required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Tri-State Outputs:** Allows bus sharing in multi-device systems.  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Alternative Part Number

  • AS6C62256-55PCN --: 32K x 8 low-power CMOS SRAM with 55 ns access time, functionally equivalent to the 32K x 8 SRAM and widely used as a drop-in replacement for legacy 62256-type parts.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM with 70 ns access time matching the original speed grade, pin-compatible with standard 28-pin DIP SRAM sockets.
  • IS62C256AL-45ULI --: 32K x 8 low-power CMOS SRAM with 45 ns access time, pin-compatible and suitable as a faster equivalent replacement for the original SRAM.
  • IS62C256AL-45TLI --: 32K x 8 low-power CMOS SRAM with 45 ns access time, faster than the original and pin-compatible for most 28-pin DIP sockets.
  • IS61C256AH-70T --: 32K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the M5M5256DP-70LL and widely available.
  • IS61C256AL-70TLI --: 32K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the M5M5256DP-70LL and widely available in a similar TSOP package.
  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM with 70 ns speed grade, direct functional replacement for the M5M5256 series with comparable pinout and timing.
  • AS6C62256-55SIN --: 32K x 8 low-power CMOS SRAM, pin-compatible with 62256-type devices, 55 ns speed meets or exceeds the 70 ns requirement and is a common drop-in substitute.
  • IS61C256AL-70T --: 32K x 8 asynchronous SRAM with 70 ns access time, pin-compatible with the M5M5256 series and widely available.
  • AS6C62256-70PCN --: 32K x 8 low-power CMOS SRAM at 70 ns, designed as a direct replacement for legacy 62256-type parts including the M5M5256.
