ADE-203-311A (Z) HN27C4000G Series 524288-Word × 8-Bit/262144-Word × 16-Bit CMOS UV Erasable and Programmable ROM Rev. 1 Nov. 10, 1994 The Hitachi HN27C4000 is a 4-Mbit UV erasable and electrically programmable ROM that is organized either as 524288-word × 8 bit or as 262144-word × 16 bit, featuring extra-high speed burst mode that gives two times faster 4-word or 8byte serial access than normal. And also high speed and fast programming are served as well as the existing Hitachi 4M device HN27C.

HN27C4000G Features

* Organization: 524288-word × 8-bit/262144word × 16-bit (BYTE /VPP enables selection byte-wide or word-wide)

* High speed: Access time 100 ns/120 ns/150 ns (max) Burst access time 50 ns/60 ns/60 ns (max)

* Low power dissipation: Standby mode; 5 µW (typ), Active mode; 150 mW/M
