| HN624416 Series 1048576-word x 16-bit/ 2097152-word x 8-bit CMOS Mask Programmable ROM ADE-203-466 (Z) Preliminary Rev. 0.0 Nov. 20, 1995 Description The HN624416 is a 16-Mbit CMOS mask-Programmable ROM organized either as 1048576 words by 16 bits or 2097152 words by 8 bits. Realizing low power consumption, this memory is allowed for battery operation. And a high speed access of 100/120 ns (max) is the most suitable to the system using a high speed microcomputer by 16 bits. Feature * Single 5 V supply * High speed Access time: 100/120 ns (max) * Low power Active: 660 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 8 Mbit Mask ROM (HN62448) Ordering Information Type No. HN624416P-10 HN624416P-12 HN624416FB-10 HN624416FB-12 HN624416TT-10 HN624416TT-12 Access time 100 ns 120 ns 100 ns 120 ns 100 ns 120 ns Package 600 mil 42-pin plastic DIP (DP-42) 600 mil 44-pin plastic SOP (FP-44D) 400 mil 44-pin plastic TSOP II (TTP-44D) Note: The specifications of this device are subject to change without notice.

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. 6 HN624416 Series Power Up Sequence VCC 4.5V 0V CE t P 0s t ACE Address Valid data t AA Dout Valid data Notes: 1. This device is used ATD (Address Transition Detecter). Therefore, transfer either CE or address (A19 to A0) after power up to 4.5V. 7 HN624416 Series Package Dimensions HN624416P Series (DP-42) Unit: mm 42 52.80 53.80 Max 22 15.0 Max 2.54 Min 5.06 Max 13.40 1 1.3 Max 1.20 21 15.24 0.51 Min 2.54 0.25 0.48 0.10 0.25 - 0.05 0 - 15 + 0.26 HN624416FB Series (FP-44D) Unit: mm 28.50 28.70 Max 44 23 12.60 3.00 Max 1 1.02 Max 22 0.17 0.05 16.04 0.30 1.72 0.40 0.10 1.27 0.10 0.12 M 0.19 0.10 0 - 10 0.80 0.20 8 HN624416 Series Package Dimensions (cont) HN624416TT Series (TTP-44D) 18.41 18.81 Max 44 23 Unit: mm 1 0.30 0.10 0.80 0.13 M 22 10.16 1.105 Max 1.20 Max 0.17 0.05 11.76 0.20 0 - 5 +0.03 -0.05 0.10 0.80 0.13 0.50 0.10 9 |
