Description and Introduction

131,072-word X 8-bit High Speed CMOS Static RAM The HM628128ALR-10SL is a high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now part of Renesas Electronics). Here are the key specifications:

- **Organization**: 128K words × 8 bits  
- **Technology**: High-speed CMOS  
- **Access Time**: 10 ns  
- **Operating Voltage**: 5V ±10%  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: 0°C to +70°C  
- **Standby Current**: Low power consumption in standby mode  
- **I/O Interface**: TTL-compatible  
- **Features**: Single +5V power supply, fully static operation (no clock or refresh required), three-state output  

This SRAM is designed for applications requiring fast access times and low power consumption.

Alternative Part Number

  • IS61C1024AL-10TLI --: 128K x 8 asynchronous SRAM with 10 ns access time, functionally equivalent to the HM628128AL series and widely available.
  • CY7C1019DV33-10ZSXI --: 128K x 8 low-power SRAM with 10 ns speed grade, pin-compatible replacement for the HM628128ALR-10SL.
  • AS6C1008-55SIN --: 128K x 8 SRAM in the same package family, drop-in alternative for legacy Hitachi HM628128 designs; note the 55 ns speed if timing is critical.
