Description and Introduction

4 M SRAM (512-kword x 8-bit) The HM628512CLP-5SL is a 512K-bit (64K x 8) high-speed CMOS static RAM (SRAM) manufactured by Hitachi. Here are its key specifications:

- **Organization**: 64K words × 8 bits  
- **Access Time**: 5 ns (max)  
- **Operating Voltage**: 5V ±10%  
- **Operating Current**: 70 mA (max)  
- **Standby Current**: 10 μA (max)  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: 0°C to +70°C  
- **Technology**: High-speed CMOS  
- **I/O Interface**: TTL-compatible  
- **Features**: Single 5V power supply, fully static operation, no clock or refresh required  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • AS6C4008-55PCN --: 512K x 8 low-power CMOS SRAM in a 32-pin DIP, functionally equivalent to the HM628512 with 55 ns access time and widely used as a drop-in replacement.
  • CY62256NLL-55PC --: 256K x 8 low-power SRAM with similar 5V interface and 55 ns speed; suitable when half the density is acceptable, from a well-established SRAM family.
  • IS62WV5128DBLL-45TLI --: 512K x 8 low-power SRAM with 45 ns access time, matching density and pinout, offering a faster and readily available alternative.
  • IS62C512-55T --: 512K x 8 asynchronous SRAM with 55 ns speed in a TSOP package, matching the density and timing of the original Hitachi part.
  • CY62512LL-55ZC --: 512K x 8 low-power SRAM with 55 ns access time, suitable as a functional substitute for the HM628512CLP-5SL in most designs.
