1 / 20 page 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 8- byte 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. Features • Organization: 524288-word × 8-bit/262144- word × 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/MHz (typ) • Fast high reliability page programming, fast high-reliability programming and option programming: Program voltage; +12.5 V DC Program time; 3.5 sec (min) (Theoretical in Page programming) • Inputs and outputs TTL compatible during both read and program modes • Pin arrangement: 40-pin EIAJ standard pin compatible with HN62414/ HN62434 • Device identifier mode: Manufacturer code and device code ADE-203-311A (Z) |
