Description and Introduction

4 M SRAM (512-kword x 8-bit) The part HM62W8512BLFP-5 is manufactured by HIT (Hynix Semiconductor Inc.). It is a 512M-bit (64M x 8) CMOS SDRAM with a synchronous interface. Key specifications include:  

- **Organization**: 64M words × 8 bits  
- **Voltage Supply**: 3.3V ± 0.3V  
- **Operating Frequency**: Up to 166 MHz  
- **Access Time**: 5.4 ns (CL=3)  
- **Package**: 54-pin TSOP-II  
- **Refresh Cycles**: 4096 refresh cycles / 64ms  
- **Operating Temperature**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

This SDRAM is commonly used in applications requiring high-speed memory, such as networking equipment, set-top boxes, and embedded systems.

Application Scenarios & Design Considerations

4 M SRAM (512-kword x 8-bit)

Alternative Part Number

  • IS61WV5128BLL-10TLI --: 512K x 8 asynchronous SRAM with similar 5V-tolerant interface and pinout; widely available and a common drop-in replacement for Hitachi 512Kx8 SRAMs.
  • CY7C1041CV33-10ZXI --: 512K x 8 high-speed asynchronous SRAM with comparable access time and organization, suitable for direct substitution in most legacy designs.
  • AS6C4008-55PCN --: 512K x 8 low-power CMOS SRAM designed as a legacy-compatible replacement for Hitachi SRAM families, with matching pinout and timing.
  • CY7C1041DV33-10ZSXI --: 512K x 8 high-speed asynchronous SRAM with comparable access time and pin-compatible footprint, suitable for replacing the Hitachi part in most designs.
