Description and Introduction

131,072-word X 8-bit High Speed CMOS Static RAM The HM628128ALP-7SL is a 1M-bit (128K-word × 8-bit) CMOS static RAM (SRAM) manufactured by Hitachi. Key specifications include:  

- **Organization**: 128K words × 8 bits  
- **Access Time**: 70 ns  
- **Operating Voltage**: 5V ±10%  
- **Operating Current**: 35 mA (typical)  
- **Standby Current**: 5 μA (typical)  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: 0°C to +70°C  
- **Technology**: CMOS  

This SRAM features a fully static operation, no clock or refresh required, and is compatible with TTL levels. It is commonly used in applications requiring low-power, high-speed memory.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • AS6C1008-55PCN --: 128K x 8 low-power CMOS SRAM in a 32-pin DIP, functionally equivalent to the HM628128 with similar access time and pinout.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM in a 28-pin DIP; a widely available alternative when a smaller density is acceptable, with comparable low-power CMOS design.
  • IS62WV1288DBLL-45TLI --: 128K x 8 low-power SRAM with similar organization and speed grade, suitable as a drop-in style replacement in many legacy designs.
