| Semiconductor MR27V401D 524,288-Word x 8-Bit One Time PROM DESCRIPTION 1A The MR27V401D is a 4Mbit electrically Programmable Read-Only Memory organized as 524,288 word x 8bit. The MR27V401D operates on a single +3V-3.3V power supply and is TTL compatible. Since the MR27V401D operates asynchronously , external clocks are not required , making this device easy-to-use. The MR27V401D is suitable as large-capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 32-pin DIP, 32-pin SOP or 32-pin TSOP packages. FEATURES * 524,288 word x 8bit * Single +3V-3.3V power supply * Access time 80ns access time (Vcc=+3V) 70ns access time (Vcc=+3.3V) * Input / Output TTL compatible * Three-state output * Packages 32-pin plastic DIP (DIP32-P-600-2.54) (Product name : MR27V401DRA) 32-pin plastic SOP (SOP32-P-525-1.27-K) (Product name : MR27V401DMA) 32-pin plastic TSOP (TSOP I 32-P-814-0.50-K) (Product name : MR27V401DTA) November 1999 1/11 MR27V401D PIN CONFIGURATION (TOP VIEW) Vpp 1 A16 2 A15 3 A12 4 A7 5 A6 6 A5 7 A4 8 A3 9 A2 10 A1 11 A0 12 D0 13 D1 14 D2 15 VSS 16 32-pin DIP 32 VCC 31 A18 30 A17 29 A14 28 A13 27 A8 26 A9 25 A11 24 OE 23 A10 22 CE 21 D7 20 D6 19 D5 18 D4 17 D3 Vpp 1 A16 2 A15 3 A12 4 A7 5 A6 6 A5 7 A4 8 A3 9 A2 10 A1 11 A0 12 D0 13 D1 14 D2 15 VSS 16 32-pin SOP 32 VCC 31 A18 30 A17 29 A14 28 A13 27 A8 26 A9 25 A11 24 OE 23 A10 22 CE 21 D7 20 D6 19 D5 18 D4 17 D3 A5 A7 A15 Vpp A18 A14 A11 A8 VCC A6 A12 A13 A9 A4 A16 A17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 32-pin TSOP 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 D3 D5 D7 A3 A1 D0 D2 A10 VSS D4 D6 A2 D1 OE CE A0 PIN NAMES A0 - A18 D0 - D7 CE OE VCC VSS VPP FUNCTIONS Address input Data output Chip enable Output enable Power supply voltage GND Program Power supply voltage 2/11 MR27V401D BLOCK DIAGRAM CE OE VPP CE OE PGM Column Decoder A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 Row Decoder Memory Matrix Address Buffer 524,288X8-Bit Multiplexer Output Buffer D0 D1 D2 D3 D4 D5 D6 D7 FUNCTION TABLE MODE READ OUTPUT DISABLE STAND-BY PROGRAM PROGRAM INHIBIT PROGRAM VERIFY * : Don't Care (H or L) ** : Don't Care (H or L or Open) CE L L H L H H OE L H * H H L 9.75V 4.0V VPP ** VCC 3.0V to 3.3V D0 - D7 DOUT Hi-Z Hi-Z DIN Hi-Z DOUT 3/11 MR27V401D ABSOLUTE MAXIMUM RATINGS Parameter Operating temperature under bias Storage temperature Input voltage Output voltage Power supply voltage Program power supply voltage Power dissipation per package Symbol Topr Tstg VI VO VCC VPP PD relative to VSS Condition Value 0 to 70 -55 to 125 -0.5 to VCC + 0.5 -0.5 to VCC + 0.5 -0.5 to 5 -0.5 to 11.5 1.0 Unit C C V V V V W RECOMMENDED OPERATING CONDITIONS (Ta=0 to 70C) Parameter VCC power supply voltage VPP power supply voltage Input "H" level Input "L" level Voltage is relative to Vss * : Vcc+1.5V (Max.) when pulse width of overshoot is less than 10nS. ** : -1.5V (Min.) when pulse width of undershoot is less than 10nS.
