Description and Introduction

131,072-word X 8-bit High Speed CMOS Static RAM The HM628128ALT-10 is a 128K x 8-bit High-Speed CMOS Static RAM (SRAM) manufactured by Hitachi (now Renesas Electronics). Here are its key specifications:

- **Organization**: 128K words × 8 bits  
- **Technology**: High-Speed CMOS  
- **Access Time**: 10 ns  
- **Operating Voltage**: 5V ±10%  
- **Operating Current**: 40 mA (typical)  
- **Standby Current**: 10 µA (typical)  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: 0°C to +70°C  
- **I/O Compatibility**: TTL  
- **Features**:  
  - Single 5V power supply  
  - Fully static operation (no clock or refresh required)  
  - Three-state outputs  
  - Directly compatible with most microprocessor systems  

This SRAM is designed for high-performance applications requiring fast access times.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS61C1024AL-10TLI --: 128K x 8 asynchronous SRAM with 10 ns access time, pin-compatible and functionally equivalent to the HM628128ALT-10.
  • CY7C1019DV33-10ZSXI --: 128K x 8 low-power SRAM with 10 ns speed grade, same JEDEC pinout and comparable timing, suitable drop-in replacement.
  • AS6C1008-55TIN --: 128K x 8 CMOS SRAM in the same package family; slower 55 ns access time but electrically compatible for non-timing-critical designs.
