HN27C4000G Series
524288-Word x 8-Bit/262144-Word x 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 x 8 bit or as 262144-word x 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 HN27C4096 and HN27C4001. Fabricated on advanced fine process and high speed circuitry technique, HN27C4000 makes high speed access time and low power dissipation in either active or stand-by mode. Therefore, it is suitable for all systems featuring high speed microprocessor such as the 80386, 80486, 68030, 68040 and so on.

Optional Page Programming
This device can be applied the optional page programming algorithm shown in the following flowchart. This algorithm allows to obtain faster programming time without any voltage stress to the device nor deterioration in reliability of programmed data. This programming algorithm is the combination of page programming and word verify. It can avoid the increase of programming verify time when a programmer with slow machine cycle is used, and shorten the total programming time. Regarding the timing specifications for page programming and word verify, please refer to the specifications for fast high-reliability page programming and fast high-reliability programming.
