Description and Introduction

4 M SRAM (512-kword x 8-bit) The part HM62W8512BLTT-7 is manufactured by HIT (Hyundai Electronics, now part of SK Hynix). Here are its specifications:

- **Type**: Synchronous DRAM (SDRAM)
- **Density**: 64Mbit (8M x 8-bit)
- **Organization**: 8 Meg words × 8 bits
- **Voltage**: 3.3V (±0.3V)
- **Speed**: 7ns (143MHz)
- **Package**: 400mil TSOP-II (54-pin)
- **Refresh**: 4096 cycles/64ms
- **Operating Temperature**: Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant
- **Features**: Fully synchronous operation, programmable burst lengths (1, 2, 4, 8, full page), auto refresh and self refresh modes, CAS latency options (2, 3).

This information is based on the available datasheet for the HM62W8512BLTT-7.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS61WV5128BLL-10TLI --: 512K x 8 asynchronous SRAM with comparable speed grade and pinout, widely available and often used as a drop-in replacement for Hitachi 512Kx8 SRAMs.
  • CY7C1041CV33-10ZXI --: 256K x 16 high-speed asynchronous SRAM in the same performance class; can replace the HM62W8512BLTT-7 in many designs with minor board adaptation.
  • AS6C4008-55TIN --: 512K x 8 low-power CMOS SRAM with compatible organization and timing, offered as a direct second-source for legacy Hitachi SRAM parts.
