Description and Introduction

4 M PSRAM (512-kword x 8-bit) 2 k Refresh The part HM658512ALP-7 is a 512K (64K x 8) CMOS SRAM manufactured by HIT (Hitachi). Here are its key specifications:

- **Organization**: 64K x 8 bits  
- **Technology**: CMOS  
- **Access Time**: 70 ns  
- **Operating Voltage**: 5V ±10%  
- **Operating Temperature Range**: Commercial (0°C to +70°C)  
- **Package**: 28-pin PLCC (Plastic Leaded Chip Carrier)  
- **Standby Current**: Low power consumption in standby mode  
- **I/O Compatibility**: TTL compatible  

This SRAM is designed for high-speed, low-power applications.

Application Scenarios & Design Considerations

4 M PSRAM (512-kword x 8-bit) 2 k Refresh

Alternative Part Number

  • IS61C512-15T --: 512K x 8 asynchronous SRAM with similar access time and pinout, widely available and a common drop-in replacement for Hitachi 512K SRAMs.
  • CY7C185-15PC --: 64K x 8 high-speed SRAM in a comparable DIP package; suitable when the full 512K density is not required and timing is compatible.
  • AS6C4008-55PCN --: 512K x 8 low-power CMOS SRAM in a 32-pin DIP, functionally equivalent to the HM658512 series with similar interface and timing.
