Description and Introduction

4 M SRAM (512-kword x 8-bit) The part **HM62V8512BLTT-7** is a **512K x 8-bit (4M-bit) CMOS Static RAM (SRAM)** manufactured by **Hitachi**.  

### Key Specifications:  
- **Organization**: 512K words × 8 bits  
- **Technology**: CMOS  
- **Access Time**: 70 ns  
- **Operating Voltage**: 5V ±10%  
- **Operating Temperature**: Commercial (0°C to +70°C)  
- **Package**: 32-pin TSOP (Thin Small Outline Package)  
- **Pin Configuration**: Compatible with other high-speed SRAMs  
- **Power Consumption**:  
  - **Active Current**: 80 mA (max)  
  - **Standby Current**: 10 mA (max)  

### Features:  
- **Low Power Consumption** in standby mode  
- **Fully Static Operation** (no refresh required)  
- **TTL-Compatible Inputs/Outputs**  
- **Single 5V Power Supply**  
- **Tri-State Outputs**  

This SRAM is commonly used in applications requiring fast, low-power memory, such as embedded systems, networking equipment, and industrial electronics.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • IS62WV5128BLL-55TLI --: 512K x 8 low-power SRAM with similar speed grade and pinout, widely available and often used as a drop-in replacement for Hitachi 512Kx8 SRAMs.
  • CY62128EV30LL-45ZXI --: 128K x 8 low-power SRAM in the same family class; check organization and package compatibility, but it is a common alternative for legacy Hitachi low-power SRAM parts.
  • AS6C62256-55SIN --: 32K x 8 low-power SRAM from a vendor that specializes in legacy SRAM replacements; verify density and pinout, but Alliance parts are frequently used to replace obsolete Hitachi SRAMs.
  • IS61LV5128AL-10TLI --: 512K x 8 asynchronous SRAM with similar 5V-tolerant interface and access time, widely available and pin-compatible in TSOP package.
  • CY7C1041CV33-10ZXI --: 512K x 8 low-power SRAM with comparable speed grade and TSOP footprint, suitable drop-in replacement for legacy Hitachi SRAM.
  • AS7C34098A-10TCN --: 512K x 8 fast asynchronous SRAM designed as a direct replacement for discontinued Hitachi HM62V series parts.
