HN58C257A Series

256k EEPROM (32-kword

8-bit)

Ready/Busy and

RES

function (HN58C257A)

ADE-203-410D (Z)

Rev. 4.0

Oct. 24, 1997

Description

The Hitachi HN58C256A and HN58C257A are electrically erasable and programmable ROMs organized as

32768-word

8-bit. They have realized high speed low power consumption and high reliability by

employing advanced MNOS memory technology and CMOS process and circuitry technology. They also

have a 64-byte page programming function to make their write operations faster.
