Semiconductor MSM534031E 524,288-Word x 8-Bit MASKROM DESCRIPTION The OKI MSM534031E is a high-speed silicon gate CMOS Mask ROM with 524,288-word x 8-bit capacity. The MSM534031E operates on a single 3.0V or 3.3V power supply but offers the same fast access times as products that operate at 5.0V. The MSM534031E's 8-bit wide data path and pin compatibility with UV erasable EPROMs make it suited for use as large capacity fixed memory for portable microcomputers and data terminals. FEATURES Single 3.0V or 3.3V power supply 524,288-words x 8-bit Access time—current consumption 150ns—15mA (3.0V±0.3V operation) 120ns—20mA (3.3V±0.3V operation) Tri-State output TTL compatible Internal powerdown function Packages: 32-PIN PLASTIC DIP (DIP32-P-600-2.54) 32-PIN PLASTIC SOP (SOP32-P-525-1.27-K) 32-PIN PLASTIC TSOP (TSOP32-P-814-0.80-K) 4MEPROM (32-PIN) pin compatible 1 MSM534031E BLOCK DIAGRAM NC 1 32 VCC A16 2 31 A18 A15 3 30 A17 A12 4 29 A14 A7 5 28 A13 A6 6 27 A8 A5 7 26 A9 A4 8 25 A11 A3 9 24 OE A2 10 23 A10 A1 11 22 CE A0 12 21 D7 D0 13 20 D6 D1 14 19 D5 D2 15 18 D4 VSS 16 17 D3 32PIN DIP,SOP A5 A4 16 A7 A6 15 14 A15 A12 13 12 A18 NC A16 11 10 VCC 9 8 A14 A17 7 A8 A13 A11 A9 6 5 4 3 2 1 27 28 29 30 31 32 TSOP TOP VIEW 17 18 A3 19 20 A1 A2 21 22 D0 A0 23 24 D2 D1 Pin Name 25 26 D3 VSS D5 D4 D7 D6 OE Function A0 to A18 Address input D0 to D7 Data output CE Chip enable OE VCC, VSS A10 CE Output enable Power supply 2 MSM534031E BLOCK DIAGRAM VCC VSS A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 Memory Cell Matrix 524,288 x 8 X Decoder Address Buffer Multiplexer CE OE Control Y Decoder Output Buffer D0 3 CE D1 D2 D3 D4 D5 OE D6 D7 MSM534031E ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings Parameter Symbol VCC Conditions Input Voltage VI to VSS Output Voltage VO Power Dissipation Operating Temperature PD Topr Storage Temperature Tstg Power Supply Voltage Rating Unit –0.3 to 7 –0.3 to VCC + 0.5 V V –0.3 to VCC + 0.5 V 1.0 W Per Package Topr = 25°C 0 to 70 °C –55 to 150 °C Recommended Operating Conditions (V CC=3.0V) Parameter Symbol Conditions Rated Value Unit Min.
