HN62454BN Series
262144-word x 16-bit CMOS Mask Programmable ROM
ADE-203-470A (Z) Rev. 1.1 Jun. 21, 1996 Description
The HN62454BN is a 262144 words by 16 bits CMOS Mask Programmable ROM, featuring page access mode to get very high speed 4-word serial access. A high speed access of 85/100 ns (max) and page access of 40 ns (max) is the most suitable to the system using a high speed micro-computer by 16 bits.
Features
* Single 5 V supply * High speed Normal access time: 85/100 ns (max) Page access time: 40 ns (max) * Low power Active: 660 mW (max) Standby: 165 W (max) * 4 word page access on word-wide mode * Directly TTL compatible All inputs and outputs * Pin compatible with 4 Mbit EPROM (HN27C4096AG/ACC/ACP)
