Description and Introduction

4 M SRAM (512-kword x 8-bit) The HM628512BLRR-5UL is a high-speed CMOS static RAM (SRAM) manufactured by HIT (now part of Renesas Electronics). Here are its key specifications:  

- **Organization**: 512K words × 8 bits  
- **Supply Voltage**: 5V ±10%  
- **Access Time**: 55 ns  
- **Operating Current**: 40 mA (typical)  
- **Standby Current**: 10 µA (typical)  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: -40°C to +85°C  
- **Technology**: High-speed CMOS  
- **I/O Compatibility**: TTL  

This SRAM is designed for applications requiring fast access times and low power consumption.

Application Scenarios & Design Considerations

4 M SRAM (512-kword x 8-bit)

Alternative Part Number

  • AS6C4008-55PCN --: 512K x 8 asynchronous SRAM with 55 ns access time, functionally equivalent to the HM628512 series and available in a comparable PDIP package.
  • IS62WV5128DBLL-45TLI --: 512K x 8 low-power CMOS SRAM with 45 ns access time, pin-compatible with the HM628512 family and suitable as a direct drop-in replacement.
  • CY62256NLL-55SNXI --: 256K x 8 low-power SRAM with 55 ns access time; a widely available alternative when half-density is acceptable, using a different product series naming.
