HN27C1024HG/HCC Series
65536-word x 16-bit CMOS UV Erasable and Programmable ROM
Description
The Hitachi HN27C1024H series is a 1-Mbit (64-kword x 16-bit) ultraviolet erasable and electrically programmable ROM. Fabricated on new advanced fine process technique, the HN27C1024H makes high speed access time 85/100 ns (max) possible. (HN27C1024H is the fastest 1-Mbit EPROM.) Therefore, it is suitable for 16-bit microcomputer systems using high speed microcomputer such as the 8086 and 68000. The HN27C1024H offers high speed programming using page programming mode. It has the package variation of cerdip 40-pin and JLCC 44-pin.
Features
* Fast high-reliability programming mode and fast high-reliability page programming mode Programming voltage: 12.5 V DC Fast High-reliability page programming 14 sec (typ) * High speed inputs and outputs TTL compatible during both read and program modes * Low power dissipation: 60 mW/MHz (typ) * Device identifier mode: Manufacturer code and device code * JEDEC standard

Erase
Erasure of HN27C4096G/CC is performed by exposure to ultraviolet light of 2537 A and all the output data are changed to "1" after this erasure procedure. The minimum integrated dose (i.e. UV intensity x exposure time) for erasure is 15 W * sec/cm2.
