Semiconductor MSM533202E 2,097,152-Word x 16-Bit or 4,194,304-Word x 8-Bit MASKROM DESCRIPTION The OKI MSM533202E is a high-speed CMOS Mask ROM that can electrically switch between 2,097,152-word x 16-bit or 4,194,304-word x 8-bit configurations. The MSM533202E operates on a single 5.0V power supply and is TTL compatible. The chip's asynchronous I/O requires no external clock assuring easy operation.A power-down mode provides low power dissipation when the chip is not selected. The CE and OE pins are provided as control signals that permit three-stated output allowing easy memory expansion on a system bus.The MSM533202E is suited for use as large capacity fixed memory for microcomputers and data terminals. FEATURES Single 5.0V power supply 2,097,152-words x 16-bit/4,194,304-words x 8-bit Access time 120ns MAX Input/Output TTL compatible Tri-State output configurations Internal powerdown function Packages: 44-PIN PLASTIC SOP (SOP44-P-600-K) 48-PIN PLASTIC TSOP (TSOP48-P-550-K) 1 MSM533202E PIN CONFIGURATION NC 1 NC 2 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 PIN SOP 44 A20 43 A19 42 A8 41 A9 40 A10 39 A11 38 A12 37 A13 36 A14 35 A15 34 A16 33 BYTE 32 VSS NC 3 A18 4 A17 5 A7 6 A6 7 A5 8 A4 9 A3 10 A2 11 A1 12 A0 13 CE 14 VSS 15 48 NC 47 NC 46 A20 45 A19 44 A8 43 A9 42 A10 41 A11 40 A12 39 A13 38 A14 37 A15 36 A16 35 BYTE 34 VSS 33 D15/A-1 32 D7 31 D14 30 D6 29 D13 28 D5 27 D12 26 D4 25 VCC 31 D15/A-1 OE 16 30 D7 D0 17 29 D14 28 D6 27 D13 26 D5 25 D12 24 D4 23 VCC D8 18 D1 19 D9 20 D2 21 D10 22 D3 23 D11 24 48 PIN TSOP Pin Name D15/A-1 A0 to A20 D0 to D15 CE OE BYTE VCC, VSS Function Data output / address input Address input Data output Chip enable Output enable Mode switch Power supply 2 MSM533202E BLOCK DIAGRAM VCC VSS A-1 BYTE Output Switching Between 8 and 16 bits CE OE CE OE Control A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 A12 A13 A14 A15 A16 A17 A18 A19 A20 X Decoder Memory Cell Matrix 2,097,152-Word x 16 or 4,194,304 x 8 Address Buffer Multiplexer Y Decoder Output Buffer D0 D1 D2 D3 D4 D5 D6 D7 D8 D10 D12 D14 D9 D11 D13 D15 FUNCTION TABLE CE H L L L L OE X H L L L BYTE X X H L L A-1/D15 X X Input Inhibited (D15) D0 to D7 Hi-Z Hi-Z D0 to D7 D0 to D7 D8 to D15 D8 to D15 Hi-Z Hi-Z D8 to D15 Hi-Z Hi-Z DOUT Mode Hi-Z 16 bit 8 bit LSB -- A0 A-1 MSB -- A20 A20 L H 3 MSM533202E ELECTRICAL CHARACTERISTICS Absolute Maximum Ratings Parameter Power Supply Voltage Input Voltage Output Voltage Power Dissipation Operating Temperature Storage Temperature Symbol VCC VI VO PD Topr Tstg Per Package Topr = 25C -- -- to VSS Conditions Limits -0.3 to 7 -0.3 to VCC + 0.5 -0.3 to VCC + 0.5 1.0 0 to 70 -55 to 150 Unit V V V W C C Recommended Operating Conditions Limits Min. 4.5 0.0 2.2 -0.3 0 Typ. 5.0 0.0 5.0 0.0 -- Max. 5.5 0.0 VCC + 0.5 0.8 70 Parameter Power Supply Voltage "H" Input Voltage "L" Input Voltage Operating Temperature Symbol VCC VSS VIH VIL Topr Conditions -- -- -- -- -- Unit V V V V C DC Characteristics (VCC = 5V10%, Ta = 0 to 70C) Parameter "H" Output Voltage "L" Output Voltage Input Leakage Current Output Leakage Current Power Supply Current (Operating) Power Supply Current (Standby) Symbol VOH VOL ILI ILO ICC ICCS1 ICCS Conditions IOH = -400A IOH = 2.1mA VI = 0 to VCC VO = 0 to VCC CE = VIH MIN CE = VIL,OE = VIH,tC = 120ns CE = VCC-0.2V CE = VIH MIN Min. 2.4 -- -10 -10 -- -- -- Limits Typ. -- -- -- -- -- -- -- Max. -- 0.4 10 10 60 50 500 Unit V V A A mA A A 4 MSM533202E AC CHARACTERISTICS Timing conditions Parameter Input Signal Level Transtion Time Timing Reference Level Load Condition Conditions VIH=2.4V, VIL=0.6V tr=tf=5ns Input Voltage=1.5V Output Voltage=0.8V&2.0V CL=100pF+1TTL Read Cycle (Ta = 0 to 70C) Parameter Cycle time Address Access time CE Access time OE Access time CE Output Disable time OE Output Disable time Output Hold time Symbol tC tACC tCE tOE tCHZ tOHZ tOH Conditions -- -- -- -- -- -- -- Limits Min. 120 -- -- -- 0 0 0 Typ. -- -- -- -- -- -- -- Max. -- 120 120 60 40 30 -- Unit ns ns ns ns ns ns ns 5 MSM533202E Read Cycle (Note 1) tC Address tACC OE tOE tOH tOHZ (Note 3) DOUT Read Cycle (Note 2) tC CE tCE OE tOE DOUT tCHZ (Note 3) Note) 1.
