Description and Introduction

8192-word x 8-bit High Speed CMOS Static RAM The HM6264LP-70 is a high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now part of Renesas Electronics). Here are the key specifications:

- **Organization**: 8K x 8-bit (65,536 bits)  
- **Access Time**: 70 ns  
- **Operating Voltage**: 5V ±10%  
- **Power Consumption**:  
  - Active: 50 mA (typical)  
  - Standby: 5 µA (typical)  
- **Package**: 28-pin DIP (Dual In-line Package)  
- **Operating Temperature Range**:  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Technology**: High-speed CMOS  
- **I/O Compatibility**: TTL  
- **Features**:  
  - Fully static operation (no clock or refresh required)  
  - Single 5V power supply  
  - Tri-state output  
  - Battery backup capability  

This SRAM is commonly used in embedded systems, industrial controls, and other applications requiring low-power, high-speed memory.

Application Scenarios & Design Considerations

8192-word x 8-bit High Speed CMOS Static RAM

Alternative Part Number

  • CY7C199-70PC --: 8K x 8 static RAM with 70 ns access time, functionally equivalent to the HM6264 and widely available as a drop-in replacement.
  • IS61C64AL-70T --: 8K x 8 low-power CMOS SRAM with 70 ns speed grade, pin-compatible with the HM6264LP and a common modern substitute.
  • AS6C6264-70PCN --: Direct 8K x 8 SRAM replacement for the HM6264 series with matching 70 ns timing and DIP package, from a vendor specializing in legacy SRAM.
  • CY62256LL-70PC --: 32Kx8 low-power SRAM in the same 28-pin DIP package with 70ns access time; a widely available drop-in replacement for the HM6264.
  • AS6C6264-55PCN --: Direct functional equivalent of the 8Kx8 HM6264 SRAM in a 28-pin DIP, with faster 55ns access and low power consumption.
  • IS62C256AL-45TLI --: Low-power 32Kx8 SRAM with compatible pinout and 70ns-class speed, suitable as a substitute when higher density is acceptable.
  • IS62C64-70PL --: 8Kx8 low-power SRAM with 70ns access time and standard DIP pinout, a common drop-in substitute for HM6264 devices.
