Description and Introduction

4 M SRAM (512-kword x 8-bit) The part HM628512CLFP-7 is a 512K x 8-bit CMOS SRAM manufactured by Hitachi (HIT). Here are its key specifications:  

- **Organization**: 512K words × 8 bits  
- **Technology**: CMOS  
- **Supply Voltage**: 5V ± 10%  
- **Access Time**: 70 ns  
- **Operating Temperature Range**: Commercial (0°C to +70°C)  
- **Package**: 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Standby Current**: Low power consumption in standby mode  
- **I/O Compatibility**: TTL-compatible inputs and outputs  
- **Refresh Requirement**: None (static RAM, no refresh needed)  

This SRAM is designed for high-speed applications requiring low power consumption.

Alternative Part Number

  • IS61C512-15T --: 512K x 8 asynchronous SRAM with similar 5V interface and access time, widely available and pin-compatible in many designs.
  • CY7C185-15PC --: 64K x 8 high-speed SRAM from a different series, suitable as a functional substitute where capacity and timing are compatible.
  • AS6C62256-55PCN --: Low-power 32K x 8 SRAM with 5V operation, a common drop-in style alternative for legacy SRAM sockets.
  • IS62C51216AL-70TLI --: 512K x 16 asynchronous SRAM with 70 ns access time in TSOP package, functionally compatible with the HM628512 series and widely available.
  • CY7C1051DV33-10ZSXI --: 512K x 16 low-power SRAM with similar organization and pinout, suitable drop-in replacement for 70 ns class applications.
  • AS6C8016-55TIN --: 512K x 16 asynchronous SRAM offered as a direct legacy replacement for Hitachi HM628512 devices, with equal or faster access time.
  • CY7C1041CV33-10ZXI --: 256K x 16 high-speed SRAM with similar pinout and timing class, suitable drop-in replacement for 5V/3.3V SRAM sockets.
  • AS6C62256-55SIN --: Low-power CMOS SRAM in the same density family, commonly used as a legacy replacement for Hitachi SRAM parts.
