Description and Introduction

64k EEPROM (8-kword x 8-bit) Ready/Busy function, RES function (HN58V66A) Wide Temperature Range version The HN58V65AT-10SR is a 64M-bit (8M x 8-bit) CMOS flash memory manufactured by HITACHI. Key specifications include:  

- **Organization**: 8M words × 8 bits  
- **Supply Voltage**: 3.3V ± 0.3V  
- **Access Time**: 100 ns (max)  
- **Operating Temperature Range**: -40°C to +85°C  
- **Package**: 32-pin SOP (Small Outline Package)  
- **Interface**: Parallel (Asynchronous)  
- **Sector Architecture**: Uniform 64K-byte sectors  
- **Endurance**: 100,000 write/erase cycles (min) per sector  
- **Data Retention**: 10 years (min)  

This device is designed for applications requiring non-volatile storage with fast read/write operations.

Alternative Part Number

  • IS61LV256-10T --: 32K x 8 asynchronous SRAM with 100 ns access time, functionally equivalent to the 8K x 8 HN58V65AT-10SR in pinout and timing class; widely available and cost-effective.
  • CY62256LL-70PXC --: 32K x 8 low-power SRAM with 70 ns access time, compatible interface and supply voltage, suitable drop-in replacement where faster timing is acceptable.
  • AS6C62256-55PCN --: 32K x 8 low-power CMOS SRAM, 55 ns access time, pin-compatible with standard 28-pin SRAM sockets and a common long-life replacement for legacy Hitachi SRAM parts.
