Description and Introduction

4 M SRAM (512-kword x 8-bit) The HM628512BLFP-7SL is a high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now part of Renesas Electronics). Here are its key specifications:

- **Organization**: 512K words × 8 bits (4Mbit)
- **Supply Voltage**: 3.3V ± 0.3V
- **Access Time**: 7ns (max)
- **Operating Current**: 70mA (typical) at 7ns access time
- **Standby Current**: 5μA (typical) in CMOS standby mode
- **Package**: 32-pin SOP (Small Outline Package)
- **Operating Temperature Range**: 0°C to +70°C
- **Interface**: Parallel (8-bit data bus)
- **Features**: 
  - Single 3.3V power supply
  - Fully static operation
  - Three-state outputs
  - TTL-compatible inputs and outputs
  - Byte control function (UB, LB) for byte-wise operation

This SRAM is designed for high-performance 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 low-power SRAM in a 32-pin DIP/TSOP-compatible package with 55 ns access, a direct functional replacement for the HM628512 series.
  • IS62WV5128BLL-55TLI --: 512K x 8 low-power CMOS SRAM with 55 ns access time, pin-compatible with the HM628512BLFP and widely available.
  • CY7C1041DV33-10ZSXI --: 512K x 8 asynchronous SRAM with similar organization and 3.3 V operation, suitable as a cross-reference alternative when timing tolerance allows.
