Description and Introduction

4 M SRAM (256-kword x 16-bit) The HM62V16256BLTT-8SL is a 4M-Word × 16-Bit CMOS Synchronous DRAM (SDRAM) manufactured by HIT. Here are its key specifications:

- **Organization**: 4M words × 16 bits  
- **Voltage Supply**: 3.3V ± 0.3V  
- **Access Time**: 8 ns (CL=3)  
- **Refresh**: 4096 refresh cycles / 64ms  
- **Operating Temperature**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package**: 54-pin TSOP-II  
- **Interface**: LVTTL  
- **Burst Length**: 1, 2, 4, 8, or full page  
- **CAS Latency**: 2, 3 programmable  
- **Auto Precharge**: Supported  
- **Data Mask**: Byte-wise control (DQM)  

This SDRAM is designed for high-speed memory applications.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS61WV25616BLL-10TLI --: 256K x 16 asynchronous SRAM with comparable 8-10 ns speed grade and 3.3V interface; widely available and pin-compatible in TSOP package.
  • CY7C1041DV33-10ZSXI --: 256K x 16 low-power SRAM with 10 ns access time, similar voltage and package, suitable drop-in replacement for cache/buffer memory.
  • AS6C25616-55TIN --: 256K x 16 SRAM in TSOP with 55 ns access; slower but functionally equivalent and cost-effective for non-timing-critical designs.
