HN58V66A - 64k EEPROM (8-kword x 8-bit) Ready/Busy function

Download the HN58V66A datasheet PDF. This datasheet also covers the HN58V65A variant, as both devices belong to the same 64k eeprom (8-kword x 8-bit) ready/busy function family and are provided as variant models within a single manufacturer datasheet.

General Description

The Hitachi HN58V65A series and HN58V66A series are a electrically erasable and programmable EEPROM’s organized as 8192-word × 8-bit.

They have realized high speed, low power consumption and high relisbility by employing advanced MNOS memory technology and CMOS process and circuitry technology.
