Description and Introduction

4 M SRAM (512-kword x 8-bit) The part **HM628512BFP-7** is a **512K-bit (64K-word × 8-bit) CMOS Static RAM (SRAM)** manufactured by **Hitachi**.  

### Key Specifications:  
- **Organization**: 64K words × 8 bits  
- **Access Time**: 70 ns  
- **Operating Voltage**: 5V ±10%  
- **Package**: 28-pin Plastic SOP (Small Outline Package)  
- **Operating Temperature Range**: Commercial (0°C to +70°C)  
- **Standby Current**: Low power consumption in standby mode  
- **I/O Compatibility**: TTL-level compatible  

This SRAM is designed for high-speed applications and features a fully static operation, meaning no refresh cycles are required.  

Would you like additional details on pin configuration or timing characteristics?

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 628512 devices.
  • CY7C1041CV33-10ZXC --: 512K x 8 low-power SRAM in a comparable package with fast access time, suitable as a functional substitute after timing verification.
  • AS6C4008-55PCN --: 512K x 8 CMOS SRAM designed as a legacy-compatible replacement for older 628512-type parts, good availability for long-life designs.
  • IS61WV5128BLL-10TLI --: 512Kx8 high-speed asynchronous SRAM in TSOP, similar pinout and voltage range, commonly cross-referenced for Hitachi 512K SRAM parts.
  • CY7C185-15PC --: 64K x 8 high-speed SRAM in the same asynchronous SRAM family class, commonly cross-referenced for Hitachi HM628512 designs.
  • AS7C512-15TC --: Alliance Memory specializes in legacy SRAM replacements and offers 512K x 8 asynchronous SRAM compatible with the HM628512 footprint and timing.
