| AC23C16200B Description 1MX16/2MX8 BIT CMOS MASK ROM The AC23C16200B high performance read only memory is organized either as 2,097,152 x 8 bit (byte mode) or as 1,048,576 x 16 bit(word mode) followed by BHE mode select. The low power feature allows the battery operation. The large size of 16M bit memory density is ideal for character generator, data or program memory in micro-processor application. The AC23C16200B is packaged 44 SOP, 48TSOP-I and 44TSOP-II. Key features * Switchable Organization Byte Mode : 2,097,152 X 8 bit Word Mode : 1,048,576 X 16 bit * Single 5V power supply operation * Access Time : 100/120ns (Max) * Standby Current : 50 (Max) * Operating Current : 60 (Max) * TTL compatible inputs and outputs * 3-State outputs for wired-OR expansion * Word or Byte switchable by BHE pin * Programmable CE or OE pin * Fully static operation * Package AC23C16200BFW : 44pin Plastic SOP(500mil) AC23C16200BTR : 48pin Plastic TSOP-1(12x20mm) AC23C16200BTF : 48pin Plastic TSOP-1(12x20mm) AC23C16200BTT : 44pin Plastic TSOP-II(400mil) Pin Description Pin A0~A19 Q0~Q14 Q15/A-1 BHE CEB* OEB* VCC VSS NC Function Address inputs Data Outputs Output Q15(Word Mode)/ LSB Address(Byte Mode) Byte High Enable input (Word/Byte selection) Chip Enable input Output Enable input Power supply Ground No Connection Pin Configuration NC A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CEB VSS OEB Q0 Q8 Q1 Q9 Q2 Q10 Q3 Q11 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 NC A19 A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS Q15/A-1 Q7 Q14 Q6 Q13 Q5 Q12 Q4 VCC 13 14 15 16 17 18 19 20 21 22 32 31 30 29 28 27 26 25 24 23 AC23V16200BTT AC23C16200BFW Page 1 of 8 * User selectable polarity 44SOP 34 33 NC A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CEB VSS OEB Q0 Q8 Q1 Q9 Q2 Q10 Q3 Q11 1 2 3 4 5 6 7 8 9 10 11 12 44 43 42 41 40 39 38 37 36 35 34 44TSOP- 33 32 31 30 29 28 27 26 25 24 23 NC A19 A8 A9 A10 A11 A12 A13 A14 A15 A16 BHE VSS Q15/A-1 Q7 Q14 Q6 Q13 Q5 Q12 Q4 VCC ARTCHIPs AC23C16200B 1MX16/2MX8 BIT CMOS MASK ROM BHE A16 A15 A14 A13 A12 A11 A10 A9 A8 A19 NC NC A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CEB 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 48TSOP-I (ROM TYPE) 37 36 35 34 33 32 31 30 29 28 27 26 25 VSS VSS Q15/A-1 Q7 Q14 Q6 Q13 Q5 Q12 Q4 VCC VCC NC Q11 Q3 Q10 Q2 Q9 Q1 Q8 Q0 OEB VSS VSS A15 A14 A13 A12 A11 A10 A9 A8 A19 NC NC NC NC NC NC A18 A17 A7 A6 A5 A4 A3 A2 A1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 48 47 46 45 44 43 42 41 40 39 38 48TSOP-I (FLASH TYPE) 37 36 35 34 33 32 31 30 29 28 27 26 25 A16 BHE VSS Q15/A-1 Q7 Q14 Q6 Q13 Q5 Q12 Q4 VCC Q11 Q3 Q10 Q2 Q9 Q1 Q8 Q0 OEB VSS CEB A0 AC23C16200BTR AC23C16200BTF Block Diagram A0~A19 ADDRESS BUFFER X-DECODER MEMORY ARRAY 16MBIT ROM CELL X-PREDEC Y-PREDEC Y-DECODER SENSE AMP CEB OEB BHE CONTROL CIRCUIT OUTPUT CIRCUIT Q0~Q15/A-1 Page 2 of 8 ARTCHIPs AC23C16200B Absolute Maximum Ratings Symbol TA TSTG VCC VOUT VIN Parameter Ambient Operating Temperature Storage Temperature Supply Voltage to Ground Potential Output Voltage Input Voltage Rating -10 ~ 80 1MX16/2MX8 BIT CMOS MASK ROM Unit -0.5 ~ 7.0 -0.5 ~ Vcc+0.5 -0.5 ~ Vcc+0.5 Stress above those listed under "absolute maximum ratings" may cause permanent damage to the device.
