| HN62W448 Series 524288-word x 16-bit/1048576-word x 8-bit CMOS Mask Programmable ROM ADE-203-544 (Z) Preliminary Rev. 0.0 May. 22, 1996 Description The Hitachi HN62W448 is a 8-Mbit CMOS mask-programmable ROM organized either as 524288-words by 16-bits or as 1048576-words by 8-bits. Realizing low power consumption with low voltage operation, this memory is allowed for battery operation. And low voltage high speed access of 120/150 ns are realized. Features * Low voltage operation : 3.3 V 0.3 V * Normal access time: 120/150 ns (max) * Low power dissipation Active: 150 mW (max) Standby: 3 W (max) * Byte-wide or word-wide data organization (Switched by BHE terminal) * Three-state data output for wired or-tying * Directly LVTTL compatible (All inputs and outputs) Ordering Information Type No. HN62W448P-12 HN62W448P-15 HN62W448FB-12 HN62W448FB-15 HN62W448TT-12 HN62W448TT-15 Access time 120 ns 150 ns 120 ns 150 ns 120 ns 150 ns Package 600mil 42-pin plastic DIP (DP-42) 44-pin plastic SOP (FP-44D) 44-pin plastic TSOP II (TTP-44D) Preliminary: This document contains information an a new product.
