HN62435 Series
262144-word x 16-bit/524288-word x 8-bit CMOS Mask Programmable ROM
ADE-203-472A(Z) Rev. 1.0 Nov. 16, 1995 Description
The HN62435 is a 4-Mbit CMOS mask-Programmable ROM organized either as 262144 words by 16 bits or 524288 words by 8 bits. Realizing a access speed of 120/150 ns (max) depend upon technology of a high speed circuit.
Features
* Single 5 V supply * High speed Access time: 120/150 ns (max) * Low power Active: 275 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)

Notes : 1. CE and OE are enable, A17 to A0 are valid. 2. D15/A-1 pin is in the output state when BHE is high, CE and OE are enable. Therefore, the input signals of opposite phase to the output must not be applied to them.
