Description and Introduction

8192-word x 8-bit High Speed CMOS Static RAM The HM6264LP-15 is a 64K (8K x 8-bit) low-power CMOS static RAM (SRAM) manufactured by Hitachi. Here are its key specifications:

- **Organization**: 8K words × 8 bits  
- **Operating Voltage**: 5V ±10%  
- **Access Time**: 150 ns  
- **Operating Current**: 20 mA (typical)  
- **Standby Current**: 10 µA (typical)  
- **Operating Temperature Range**: 0°C to +70°C  
- **Package**: 28-pin DIP (Dual In-line Package)  
- **Technology**: CMOS  
- **Data Retention Voltage**: 2V (min)  
- **Pin-Compatible**: With JEDEC-standard 6264 SRAMs  

This SRAM is designed for low-power applications and features a battery backup capability for data retention.

Application Scenarios & Design Considerations

8192-word x 8-bit High Speed CMOS Static RAM

Alternative Part Number

  • CY62256LL-70SNXC --: 32Kx8 low-power SRAM in the same 28-pin DIP footprint; faster 70ns access and widely available, a common drop-in upgrade for 8Kx8 SRAM sockets.
  • AS6C6264-55PCN --: Direct 8Kx8 low-power CMOS SRAM in 28-pin DIP with 55ns access, functionally equivalent to the HM6264LP and often used as a replacement for legacy Hitachi SRAMs.
  • IS62C256AL-45TLI --: 32Kx8 low-power SRAM in a 28-pin package with 45ns access; pin-compatible upgrade path for 6264-type sockets and readily stocked.
  • CY62256LL-70PXC --: 32Kx8 low-power SRAM in a 28-pin DIP with a compatible asynchronous interface; a widely available drop-in style replacement for 8Kx8 SRAM sockets when address space allows.
  • IS62C256AL-45ULI --: Low-power 32Kx8 SRAM in a 28-pin DIP with fast access time; a common modern substitute for legacy 6264-type SRAMs in retro and embedded designs.
  • CY7C199-15PC --: 8K x 8 asynchronous SRAM with 150 ns access time, pin-compatible with the 6264 pinout and widely available as a direct functional replacement.
  • IS61C64AL-15T --: 8K x 8 low-power CMOS SRAM in a 28-pin DIP, same 150 ns speed grade and pinout, suitable drop-in substitute for the HM6264LP-15.
