Description and Introduction

4M High Speed SRAM (256-kword x 16-bit) The HM62W16255HJP-12 is a 256K x 16-bit (4Mb) high-speed CMOS static RAM (SRAM) manufactured by HIT (Hitachi). Here are its key specifications:  

- **Organization**: 256K words × 16 bits  
- **Technology**: High-speed CMOS  
- **Operating Voltage**: 5V ± 10%  
- **Access Time**: 12 ns (max)  
- **Operating Current**: 120 mA (typical)  
- **Standby Current**: 10 mA (typical in CMOS standby mode)  
- **Package**: 44-pin SOP (Small Outline Package)  
- **Operating Temperature Range**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **I/O Interface**: TTL-compatible  
- **Features**:  
  - Single 5V power supply  
  - Fully static operation (no clock or refresh required)  
  - Three-state outputs  
  - Common data input/output  

This SRAM is designed for high-performance applications requiring fast access times and low power consumption.

Application Scenarios & Design Considerations

4M High Speed SRAM (256-kword x 16-bit)

Alternative Part Number

  • IS61WV25616EDBLL-10TLI --: 256K x 16 asynchronous SRAM with 10 ns access time, functionally equivalent to the 256K x 16 SRAM and a common drop-in replacement in the same speed grade.
  • CY7C1041DV33-10ZSXI --: 256K x 16 high-speed asynchronous SRAM with 10 ns access time, widely used as an alternative to HM62W series parts with compatible pinout and timing.
  • AS6C4008-55PCN --: 512K x 8 low-power CMOS SRAM from a different series; usable alternative when 8-bit organization is acceptable, with similar asynchronous interface and 5V/3.3V family options.
  • CY7C1041G-10ZSXI --: 256K x 16 fast asynchronous SRAM with 10 ns speed grade, matching the original device's organization and timing.
  • AS6C62256-55SIN --: Low-power 256K x 16 SRAM in a similar package, suitable as a drop-in replacement though with slower 55 ns access time.
