Description and Introduction

256 k High Speed SRAM (32-kword 8-bit) The HM62832UHLP-20 is a 32K-word × 8-bit low-power CMOS static RAM (SRAM) manufactured by Hitachi. Here are its key specifications:  

- **Organization**: 32K × 8 bits  
- **Supply Voltage**: 4.5V to 5.5V  
- **Access Time**: 200 ns  
- **Operating Current**: 15 mA (max)  
- **Standby Current**: 10 µA (max)  
- **Package**: 28-pin plastic DIP (Dual In-line Package)  
- **Operating Temperature Range**: -40°C to +85°C  
- **Technology**: CMOS  
- **Data Retention Voltage**: 2V (min)  
- **Tri-State Outputs**: Yes  

This SRAM is designed for low-power applications and features a standby mode to reduce power consumption.

Alternative Part Number

  • IS61C256AL-20N --: 32K x 8 asynchronous SRAM with 20 ns access time, pin-compatible with the HM62832U series and widely available.
  • CY62256NLL-20ZXI --: 32K x 8 low-power SRAM, 20 ns speed grade, same JEDEC pinout and function as the original part.
  • AS6C62256-55SIN --: 32K x 8 CMOS SRAM in the same package family; slower 55 ns access but a direct functional drop-in when timing is not critical.
  • IS61C1024AL-20T --: 128K x 8 asynchronous SRAM with 20 ns access time, functionally equivalent to the HM62832U series and widely available.
  • CY7C1021CV33-20ZXC --: 1M-bit (128K x 8) fast asynchronous SRAM with 20 ns speed grade, suitable drop-in replacement for the original Hitachi part.
  • AS6C1008-55TIN --: 128K x 8 low-power CMOS SRAM in the same density class; check timing since 55 ns is slower than the original 20 ns version.
