Description and Introduction

4M SRAM (512 KWORD X 8 BIT) The HM628512ALTT-7 is a high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now Renesas Electronics). Here are the key specifications:

1. **Density**: 512Kb (64K words × 8 bits)  
2. **Technology**: High-speed CMOS  
3. **Access Time**: 70ns  
4. **Operating Voltage**: 5V ±10%  
5. **Operating Current**: 70mA (typical)  
6. **Standby Current**: 10μA (typical)  
7. **Package**: 32-pin TSOP (Thin Small Outline Package)  
8. **Temperature Range**: Commercial (0°C to +70°C)  
9. **I/O Interface**: TTL-compatible  
10. **Features**: Single 5V power supply, fully static operation, no clock or refresh required, three-state output.  

This SRAM is commonly used in applications requiring high-speed, low-power memory, such as embedded systems and industrial electronics.

Application Scenarios & Design Considerations

4M SRAM (512 KWORD X 8 BIT)

Alternative Part Number

  • IS61C512-15T --: 512K x 8 asynchronous SRAM with similar access time and pinout, direct functional replacement from a different vendor.
  • CY7C199-15PC --: 32K x 8 high-speed SRAM in the same family class; widely available alternative with comparable timing.
  • AS7C512-15TC --: 512K x 8 low-power CMOS SRAM offered as a drop-in replacement for Hitachi 628512 series parts.
