¡ Semiconductor MR27V452D 262,144-Word x 16-Bit or 524,288-Word x 8-Bit 8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM DESCRIPTION 1A The MR27V452D is a 4Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 262,144 word x 16bit and 524,288 word x 8bit. The MR27V452D operates on a single +3.3V power supply and is TTL compatible. The MR27V452D provides Page mode which can greatly reduce the read access time. Since the MR27V452D operates asynchronously , external clocks are not required , making this device easy-to-use. The MR27V452D 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 40-pin DIP , 40-pin SOP or 44-pin TSOP packages. FEATURES • 262,144 word x 16bit / 524,288 word x 8bit electrically switchable configuration • Single +3.3V power supply • Access time 100ns Page mode access time 30ns • Input / Output TTL compatible • Three-state output • Packages 40-pin plastic DIP (DIP40-P-600-2.54) (Product name : MR27V452DRP) 40-pin plastic SOP (SOP40-P-525-1.27-K) (Product name : MR27V452DMP) 44-pin plastic TSOP (TSOP II 44-P-400-0.80-K) (Product name : MR27V452DTP) November 1999 1/10 MR27V452D PIN CONFIGURATION (TOP VIEW) NC 1 NC 2 A17 1 A7 2 A6 3 A5 4 A4 5 A3 6 A2 7 A1 8 A0 9 CE 10 VSS 11 OE 12 D0 13 D8 14 D1 15 D9 16 D2 17 D10 18 D3 19 D11 20 40 A8 39 A9 38 A10 37 A11 36 A12 35 A13 34 A14 33 A15 32 A16 31 BYTE/Vpp 30 VSS 29 D15/A-1 28 D7 27 D14 26 D6 25 D13 24 D5 23 D12 22 D4 21 VCC A17 3 A7 4 A6 5 A5 6 A4 7 A3 8 A2 9 A1 10 A0 11 CE 12 VSS 13 OE 14 D0 15 D8 16 D1 17 D9 18 D2 19 D10 20 D3 21 D11 22 44 NC 43 NC 42 A8 41 A9 40 A10 39 A11 38 A12 37 A13 36 A14 35 A15 34 A16 33 BYTE/Vpp 32 VSS 31 D15/A-1 30 D7 29 D14 28 D6 27 D13 26 D5 25 D12 24 D4 23 VCC 40-pin DIP , SOP 44-pin TSOP (II) PIN NAMES D15/A-1 A0 - A17 D0 - D14 CE OE VCC VSS BYTE/VPP NC Address input Data output Chip enable Output enable FUNCTIONS Data output / Address input Power supply voltage GND Mode switch / Program power supply voltage Non connection 2/10 MR27V452D BLOCK DIAGRAM A-1 X8/X16 Switch CE OE BYTE/VPP PGM CE OE Column Decoder A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 Row Decoder Memory Matrix Address Buffer 262,144X16-Bit or 524,288X8-Bit Multiplexer & Page Data Latch Output Buffer D0 D1 D2 D3 D4 D5 D6 D7 D8 D10 D9 D12 D14 D15 D11 D13 In 8-bit output mode, these pins are three-stated and pin D15 functions as the A-1 address pin.
