3 / 8 page No. 5192-3/8 LC895195 Pin Functions Type: I: Input pin, O: Output pin, B: Bidirectional pin, P: Power supply pin, NC: No connection pin Note: 1. NC (no connection) pins must be left open. 2. Pin names (signal names) that begin with a Z have negative (inverted) logic. 3. VSS0 is the logic system ground and VSS1 is the IDE interface driver ground. Pin No. Symbol Type Function 1 VSS0 P 2 ZRAS0 O Buffer DRAM RAS signal output 0 (This pin is used normally.) 3 ZRAS1 O Buffer DRAM RAS signal output 1 4 VSS0 P 5 ZCAS0 O Buffer DRAM CAS signal output 0 (This pin is used normally.) 6 ZCAS1 O Buffer DRAM CAS signal output 1 7 VSS0 P 8 ZOE O Buffer RAM output enable 9 ZUWE O Buffer RAM upper write enable 10 ZLWE O Buffer RAM lower write enable 11 RA0 O 12 RA1 O 13 RA2 O 14 RA3 O RA0 to RA6 are the data buffer DRAM address signal output. 15 RA4 O 16 RA5 O 17 RA6 O 18 VDD P 19 VSS0 P 20 RA7 O 21 RA8 O RA7 to RA9 are the data buffer DRAM address signal output. 22 RA9 O 23 VSS0 P 24 TEST0 NC 25 NC 26 TEST1 NC 27 TEST2 NC 28 TEST3 NC 29 NC 30 IO0 B 31 IO1 B Data buffer DRAM data I/O 32 IO2 B These pins have built-in pull-up resistors. 33 IO3 B 34 IO4 B 35 IO5 B 36 VSS0 P 37 VDD P 38 IO6 B 39 IO7 B 40 IO8 B 41 IO9 B Data buffer DRAM data I/O 42 IO10 B These pins have built-in pull-up resistors. 43 IO11 B 44 IO12 B 45 IO13 B 46 IO14 B 47 IO15 B 48 EXCK O SUB-CODE I/O 49 WFCK I 50 SBSO I |
