Description and Introduction

1 M SRAM (128-kword x 8-bit) The part HM628128DLP-7 is a 1M-bit (128K x 8-bit) CMOS static RAM manufactured by HIT (Hitachi). Here are its key specifications:

- **Organization**: 128K words × 8 bits  
- **Technology**: CMOS  
- **Supply Voltage**: 5V ±10%  
- **Access Time**: 70ns  
- **Operating Current**: 40mA (max)  
- **Standby Current**: 10μA (max)  
- **Package**: 32-pin DIP (Dual In-line Package)  
- **Operating Temperature Range**: 0°C to +70°C  
- **Tri-State Outputs**: Yes  
- **Data Retention Voltage**: 2V (min)  

This SRAM is compatible with TTL levels and features a fully static operation, requiring no clocks or refresh cycles.

Application Scenarios & Design Considerations

1 M SRAM (128-kword x 8-bit)

Alternative Part Number

  • IS61C1024AL-15T --: 128K x 8 asynchronous SRAM with similar 5V interface and access time class; widely available and pin-compatible in the same DIP/TSOP footprint family.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM in DIP package; a common drop-in style replacement when a smaller density is acceptable, with comparable timing and 5V operation.
  • AS6C1008-55PCN --: 128K x 8 low-power CMOS SRAM in 32-pin DIP, functionally equivalent to the HM628128 series and often used as a direct replacement.
