HN62454 Series
524288-word x 8-bit/ 262144-word x 16-bit CMOS Mask Programmable ROM
ADE-203-402A (Z) Rev. 1.0 May. 9, 1996 Description
The HN62454 is a 4-Mbit CMOS mask-Programmable ROM organized either as 262144 words by 16 bits or 524288 words by 8 bits. Realizing low power consumption, this memory is allowed for battery operation. And a high speed access of 100 ns (max) is the most suitable to the system using a high speed microcomputer by 16 bits.
Features
* Single 5 V supply * High speed Access time: 100 ns (max) * Low power Active: 330 mW (max) Standby: 165 W (max) * Byte-wide or word-wide data organization (Switched by BHE terminal) * Three-state data output for or-tying * Directly TTL compatible All inputs and outputs * Pin compatible with 4 Mbit EPROM (HN27C4000G/FP)
