| HN62448 Series 524288-word x 16-bit/1048576-word x 8-bit CMOS Mask Programmable ROM ADE-203-397B (Z) Rev. 2.0 Oct. 2, 1996 Description The Hitachi HN62448 is a 8-Mbit CMOS mask-programmable ROM organized either as 524288-words by 16-bits or as 1048576-words by 8-bits. And a high speed access of 100/120 ns is the most suitable to the system using a high speed microcomputer by 16 bits. Features * Single 5 V power supply * Access time: Normal access time: 100/120 ns (max) * Low power dissipation Active: 300 mW (typ) Standby: 5 W (typ) * Byte-wide or word-wide data organization with BHE * Three-state data output for wired or-tying * Directly TTL compatible (All input and output) Ordering Information Type No. HN62448P-10 HN62448P-12 HN62448FB-10 HN62448FB-12 HN62448TT-10 HN62448TT-12 Access time 100 ns 120 ns 100 ns 120 ns 100 ns 120 ns Package 600mil 42-pin plastic DIP (DP-42) 44-pin plastic SOP (FP-44D) 44-pin plastic TSOP II (TTP-44D) HN62448 Series Pin Arrangement HN62448P Series A18 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 21 (Top View) (Top View) HN62448TT Series NC A18 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 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 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 NC A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS D15/A-1 D7 D14 D6 D13 D5 D12 D4 VCC NC A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CE VSS OE D0 D8 D1 D9 D2 D10 D3 D11 HN62448FB Series 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 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 HN62448 Series Pin Description Pin name A0 to A18 D0 to D14 D15/A-1 OE CE BHE VCC VSS NC Function Address input Data output Data output/address input Output enable Chip enable Byte/word selection Power supply Ground No connection Block Diagram A0 to A15 Address buffer A16 to A18 X decoder Memory array Y decoder Y gates (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) *2 D0 to D15/(D7) Note: 1.

CE and OE are enable A18 to A0 are valid. 6. 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. 7. This device is used ATD (Address Transient Detector). Therefore, transfer either CE or address (A2 to A18) after power up to 4.5 V. 5 HN62448 Series Timing Waveforms Word Mode (BHE = `VIH') or Byte Mode (BHE = `VIL ')* 2,3,4 tRC Address tAA CE tCLZ OE tOLZ Dout Valid data tOE tOHZ tDHO High-Z tACE tCHZ tDHC tDHA Word Mode, Byte Mode Switch*5, 6 High-Z tAA BHE tBHZ D7 to D0 tDHB D15 to D8 High-Z Valid data tBLZ Valid data tBHE Valid data tDHA High-Z Address 6 HN62448 Series Power Up Sequence*7 4.5V VCC 0V tACE CE t Address (A2 to A18) tAA Dout t 0ns Valid data Valid data 7 HN62448 Series Package Dimensions HN62448P 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 HN62448FB Series (FP-44D) 28.50 28.70 Max 44 23 12.60 Unit: mm 3.00 Max 1 1.02 Max 22 0.17 0.05 16.04 0.30 1.72 0.19 0.10 0 - 10 0.80 0.20 0.40 0.10 1.27 0.10 0.12 M 8 HN62448 Series Package Dimensions (cont.)
