12 mA Output Drivers ISA Host Interface 16 Bit Address Qualification 160 Pin QFP Package - GENERAL DESCRIPTION The FDC37C93x incorporates a keyboard interface, real-time clock, SMSC's true CMOS 765B floppy disk controller, advanced digital data separator, 16 byte data FIFO, two 16C550 compatible UARTs, one Multi-Mode parallel port which includes ChiProtect circuitry plus EPP and ECP support, IDE interface, on-chip 24 mA AT bus drivers, game port chip select and two floppy direct drive support. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures in addition to providing data overflow and underflow protection. The SMSC advanced digital data separator incorporates SMSC's patented data separator technology, allowing for ease of testing and use. Both on-chip UARTs are compatible with the NS16C550. The parallel port, the IDE interface, and the game port select logic are compatible with IBM PC/AT architecture, as well as EPP and ECP. The FDC37C93x incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The FDC37C93x provides support for the ISA Plug-and-Play Standard (Version 1.0a) and provides for the recommended functionality to support Windows '95. Through internal configuration registers, each of the FDC37C93x's logical device's I/O address, DMA channel and IRQ channel may be programmed. There are 480 I/O address location options, 13 IRQ options, and three DMA channel options for each logical device. The FDC37C93x does not require any external filter components and is, therefore, easy to use and offers lower system cost and reduced board area. The FDC37C93x is software and register compatible with SMSC's proprietary 82077AA core. 3 PIN CONFIGURATION nDTR2 nCTS2 nRTS2 nDSR2 TXD2 RXD2 nDCD2 nRI2 nDCD1 nRI1 nDTR1 nCTS1 nRTS1 nDSR1 TXD1 RXD1 nSTB nALF nERROR nINIT nSLCTIN VCC PD0 PD1 PD2 PD3 PD4 PD5 PD6 PD7 GND nACK BUSY PE SLCT VCC XTAL2 GND XTAL1 VBAT GND DRVDEN0 DRVDEN1 nMTR0 nDS1 nDS0 nMTR1 GND nDIR nSTEP nWDATA nWGATE nHDSEL nINDEX nTRK0 nWRTPRT nRDATA nDSKCHG MEDIA_ID1 mEDIA_ID0 VCC CLOCKI nIDE1_OE nHDCS0 nHDCS1 IDE1_IRQ nHDCS2/SA13 nHDCS3/SA14 IDE2_IRQ/SA15 nIOROP nIOWOP A2 A1 A0 24CLK 16CLK CLK01 CLK02 CLK03 GND 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 FDC37C93x 160 Pin QFP 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 nROMDIR nROMCS RD7 RD6 RD5 RD4 RD3 RD2 RD1 RD0 GP25 GP24 GP23 GP22 GP21 GP20 GP17 GP16 GP15 VCC GP14 GP13 GP12 GP11 GP10 GND MCLK MDAT KCLK KDAT IOCHRDY TC DRQ3 nDACK3 DRQ2 nDACK2 DRQ1 nDACK1 DRQ0 nDACK0 SA0 SA1 SA2 SA3 SA4 SA5 SA6 SA7 SA8 SA9 SA10 SA11 nCS/SA12 IRQ15 IRQ14 IRQ12 IRQ11 IRQ10 IRQ9 VCC IRQ8/nIRQ8 IRQ7 IRQ6 IRQ5 IRQ4 IRQ3 IRQ1 nIOR nIOW AEN GND SD0 SD1 SD2 SD3 SD4 SD5 SD6 SD7 RESET_DRV 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 4 DESCRIPTION OF PIN FUNCTIONS PIN NO. 72:79 41:52 53 70 90 80
