Semiconductor MSM27C852CZ 524,288-Word x 16-Bit or 1,048,576-Word x 8-Bit 8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM DESCRIPTION 1A The MSM27C852CZ is a 8Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 524,288 word x 16bit and 1,048,576 word x 8bit. The MSM27C852CZ operates on a single +5V power supply and is TTL compatible. The MSM27C8 52CZ provides Page mode which can greatly reduce the read access time. Since the MSM27C852 CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C852CZ 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 42-pin DIP , 44-pin SOP or 44-pin TSOP packages. FEATURES * 524,288 word x 16bit / 1,048,576 word x 8bit electrically switchable configuration * Single +5V power supply * Access time 100ns Page mode access time 50ns * Input / Output TTL compatible * Three-state output * Packages 42-pin plastic DIP (DIP42-P-600-2.54) 44-pin plastic SOP (SOP44-P-600-1.27-K) 44-pin plastic TSOP (TSOP II 44-P-400-0.80-K) 1 MSM27C852CZ PIN CONFIGURATION (TOP VIEW) A18 1 A17 2 A7 3 A6 4 A5 5 A4 6 A3 7 A2 8 A1 9 A0 10 CE 11 VSS 12 OE 13 D0 14 D8 15 D1 16 D9 17 D2 18 D10 19 D3 20 D11 21 42 NC 41 A8 40 A9 39 A10 38 A11 37 A12 36 A13 35 A14 34 A15 33 A16 32 BYTE/Vpp 31 VSS 30 D15/A-1 29 D7 28 D14 27 D6 26 D13 25 D5 24 D12 23 D4 22 VCC 42-pin DIP NC 1 A18 2 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 44-pin SOP NC 1 A18 2 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 44-pin TSOP PIN NAMES D15/A-1 A0 - A18 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 MSM27C852CZ BLOCK DIAGRAM A-1 X8/X16 Switch CE OE BYTE/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 524,288X16-Bit or 1,048,576X8-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.
