| HN62V454 Series 524288-word x 8-bit/ 262144-word x 16-bit CMOS Mask Programmable ROM ADE-203-615A (Z) Rev. 1.0 Jul. 4, 1996 Description The HN62V454 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 200 ns (max) is the most suitable to the system using a high speed microcomputer by 16 bits. Features * Low voltage operation Operating supply voltage: 2.7 to 3.6 V * High speed Access time: 200 ns (max) * Low power Active: 72 mW (max) Standby: 72 W (max) * Byte-wide or word-wide data organization (Switched by BHE terminal) * Three-state data output for or-tying * Directly LVTTL compatible All inputs and outputs Ordering Information Type No. HN62V454P-20 HN62V454FA-20 HN62V454TT-20 Access time 200 ns 200 ns 200 ns Package 600 mil 40-pin plastic DIP (DP-40) 525 mil 40-pin plastic SOP (FP-40D) 400 mil 44-pin plastic TSOP II (TTP-44D) HN62V454 Series Pin Arrangement HN62V454P Series A17 A7 A6 A5 A4 A3 A2 A1 A0 CE VSS OE D0 D8 D1 D9 D2 D10 D3 D11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 (Top view) HN62V454FA Series A17 A7 A6 A5 A4 A3 A2 A1 A0 CE VSS OE D0 D8 D1 D9 D2 D10 D3 D11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 (Top view) 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS D15/A-1 D7 D14 D6 D13 D5 D12 D4 VCC 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS D15/A-1 D7 D14 D6 D13 D5 D12 D4 VCC NC NC A17 A7 A6 A5 A4 A3 A2 A1 A0 CE VSS OE D0 D8 D1 D9 D2 D10 D3 D11 HN62V454TT Series 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 (Top view) 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 NC NC A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS D15/A-1 D7 D14 D6 D13 D5 D12 D4 VCC 2 HN62V454 Series Pin Description Pin name A-1, A0 to A17 D0 to D15 BHE CE OE NC VDD VSS Function Address inputs Data outputs 8/16 bit (byte/word) mode switch Chip enable Output enable No connection Power supply Ground Block Diagram A12 A2 X decoder Memory array A17 A13 Address buffer Ydecoder Y gates A1 A0 (A-1) *1 Hex / Byte BHE OE 3-state output buffer CE BHE = VIH : 16-bit (D15 to D0) BHE = VIL : 8-bit (D7 to D0) Note: 1.
