Description and Introduction

131,072-word X 8-bit High Speed CMOS Static RAM The HM628128ALT-5L is a 1M-bit (128K x 8-bit) CMOS static RAM (SRAM) manufactured by Hitachi (now Renesas Electronics). Here are its key specifications:  

- **Organization**: 128K words × 8 bits  
- **Operating Voltage**: 5V ±10%  
- **Access Time**: 55 ns (max)  
- **Operating Current**: 40 mA (typical)  
- **Standby Current**: 10 μA (typical, CMOS level)  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: -40°C to +85°C  
- **Technology**: CMOS  
- **Pin Configuration**: Compatible with standard 128K × 8 SRAMs  

This SRAM is designed for high-speed, low-power applications and is commonly used in embedded systems and industrial electronics.

Application Scenarios & Design Considerations

131,072-word X 8-bit High Speed CMOS Static RAM

Alternative Part Number

  • IS62C1024AL-55T --: 128K x 8 low-power CMOS SRAM with 55 ns access time, functionally equivalent to the HM628128ALT-5L and pin-compatible in most 32-pin TSOP/DIP layouts.
  • AS6C1008-55TIN --: 128K x 8 asynchronous SRAM rated at 55 ns, direct drop-in replacement for Hitachi 628128 series with similar supply voltage and pinout.
  • CY62256NLL-55ZXI --: 32K x 8 low-power SRAM with 55 ns speed; suitable when half-density is acceptable, widely available and electrically compatible with the same bus interface.
