Pin Number Pin Name PWR I/O Pin Description
11 SELSDR_DDR#/ PCI1 VDDPCI I/O PD Power-on Bidirectional Input/Output. At power-up, SELSDR_DDR is the input. When the power supply voltage crosses the input threshold voltage, SELSDR_DDR state is latched and this pin becomes PCI clock output. SeISDR_DDR#.= 0, DDR Mode. SeISDR_DDR#.= 1, SDR Mode.
21 FS2/24 48M VDD48M I/O PD Power-on Bidirectionallnput/Output. At power-up, FS2 is the input. When the power supply voltage crosses the input threshold voltage, FS2 state is latched and this pin becomes 24_48M, a Slo programmable clock output.
6 AGPO VDDAGP O AGP Clock Output. Is synchronous to CPU clocks. See Table 7
8 AGP2 VDDAGP O AGP Clock Output. Is synchronous to CPU clocks. See Table 7
25 IREF I Current reference programming input for CPU buffers. A precise resistor is attached to this pin, which is connected to the internal current reference.
28 SDATA 1/0 Serial Data Input. Conforms to the Phillips 12C specification of a Slave Receive/Transmit device. It is an input when receiving data. It is an open drain output when acknowledging or transmitting data.
27 SCLK I Serial Clock Input. Conforms to the Philips 12C specification.
26 PD/SRESET# I/O PU Power-downlnput/System Reset Control Output. If Byte6 Bit7 = O(default), this pin becomes a SRESET# open drain output. See system resetdescription. If Byte6Bit7 = 1, this pin becomes PD# input with an internal pull-up. When PD# is asserted low, the device enters power down mode. See power management function.
45 BUF IN If SeISDR_DDR.= 0, 2.5V CMOS type input to the DDR differential buffers. If SeISDR_DDR#.= 1, 3.3V CMOS type input to the SDR buffer.
46 FBOUT If SeISDR_DDR#.= 0, 2.5V single ended SDRAM buffered output of the signal applied at BUF_IN. It is in phase with the DDRT(0:5) signals.lf SeISDR_DDR#.= 1, 3.3V single ended SDRAM buffered output of the signal applied at BUF_IN. It is in phase with the SDRAM(O:11) signals
