Description

The Hitachi HN58V1001 is a electrically erasable and programmable ROM organized as 131072-word

× 8-

bit. It has realized high speed, low power consumption and high reliability by employing advanced MNOS

memory technology and CMOS process and circuitry technology. It also has a 128-byte page programming

function to make the write operations faster.
