Description and Introduction

4 M SRAM (512-kword x 8-bit) The HM62V8512CLTT-7 is a 512K x 8-bit high-speed CMOS static RAM (SRAM) manufactured by Hitachi (now part of Renesas Electronics). Here are its key specifications:  

- **Organization**: 512K words × 8 bits  
- **Technology**: High-speed CMOS  
- **Supply Voltage**: 3.3V ± 0.3V  
- **Access Time**: 70 ns (max)  
- **Operating Current**: 40 mA (typical)  
- **Standby Current**: 10 µA (typical, with CMOS level inputs)  
- **Package**: 32-pin TSOP (Thin Small Outline Package)  
- **Operating Temperature Range**: Commercial (0°C to +70°C)  
- **I/O Interface**: 3.3V TTL-compatible  
- **Data Retention**: Supported with reduced voltage (2V min)  

This SRAM is commonly used in applications requiring low-power, high-speed memory, such as embedded systems and networking devices.

Alternative Part Number

  • IS62WV5128DBLL-45TLI --: 512K x 8 low-power asynchronous SRAM with similar 5V-tolerant interface and access time, direct functional replacement in the same memory class.
  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM with compatible parallel interface and timing, widely used as a drop-in substitute for similar Hitachi SRAM parts.
  • AS6C62256-55SIN --: Low-power 32K x 8 CMOS SRAM pin-compatible with common 62256-type devices, offering comparable speed and voltage range for legacy designs.
  • IS61LV5128AL-10TLI --: 512K x 8 asynchronous SRAM with similar 5V-tolerant interface and access time, widely available drop-in style replacement for the HM62V8512 series.
  • CY7C1041CV33-10ZXI --: 4Mbit asynchronous SRAM in the same density class with comparable speed grade and pinout, suitable as a functional substitute.
  • AS6C4008-55TIN --: 4Mbit low-power asynchronous SRAM offering similar organization and timing, commonly used to replace Hitachi HM62 series parts.
