Spartan-3A DSP FPGA Family: Pinout DescriptionsDS610 (v3.0) October 4, 2010 www.xilinx.comProduct Specification 66CS484: 484-Ball Chip-Scale Ball Grid ArrayThe 484-ball chip-scale ball grid array, CS484, supportsboth the XC3SD1800A and XC3SD3400A FPGAs. Thereare no pinout differences between the two devices.Table 63 lists all the CS484 package pins. They are sortedby bank number and then by pin name. Pairs of pins thatform a differential I/O pair appear together in the table. Thetable also shows the pin number for each pin and the pintype, as defined earlier.An electronic version of this package pinout table andfootprint diagram is available for download from the Xilinxwebsite atwww.xilinx.com/support/documentation/data_sheets/s3a_pin.zipPinout TableTable 63: Spartan-3A DSP CS484 PinoutBank Pin Name CS484Ball Type0 IO_L30N_0 A3 I/O0 IO_L28N_0 A4 I/O0 IO_L25N_0 A5 I/O0 IO_L25P_0 A6 I/O0 IO_L24N_0/VREF_0 A7 VREF0 IO_L20P_0/GCLK10 A8 GCLK0 IO_L18P_0/GCLK6 A9 GCLK0 IP_0 A10 INPUT0 IO_L15N_0 A11 I/O0 IP_0 A12 INPUT0 IO_L11P_0 A13 I/O0 IO_L10P_0 A14 I/O0 IP_0 A15 INPUT0 IO_L06P_0/VREF_0 A16 VREF0 IO_L06N_0 A17 I/O0 IP_0 A18 INPUT0 IO_L07N_0 A19 I/O0 IO_0 A20 I/O0 IO_L30P_0 B3 I/O0 IO_L28P_0 B4 I/O0 IO_L24P_0 B6 I/O0 IO_L20N_0/GCLK11 B8 GCLK0 IO_L18N_0/GCLK7 B9 GCLK0 IO_L15P_0 B11 I/O0 IO_L11N_0 B13 I/O0 IO_L10N_0 B15 I/O0 IO_L03P_0 B17 I/O0 IO_L02N_0 B19 I/O0 IO_L07P_0 B20 I/O0 IO_L29N_0 C4 I/O0 IP_0 C5 INPUT0 IO_L21P_0 C6 I/O0 IO_L26P_0 C7 I/O0 IO_L22P_0 C8 I/O0 IO_L16P_0 C9 I/O0 IP_0 C10 INPUT0 IP_0/VREF_0 C11 VREF0 IO_L14N_0 C12 I/O0 IO_L14P_0 C13 I/O0 IP_0 C14 INPUT0 IO_L12N_0/VREF_0 C15 VREF0 IO_L08N_0 C16 I/O0 IO_L03N_0 C17 I/O0 IO_L02P_0/VREF_0 C18 VREF0 IO_L01N_0 C19 I/O0 IO_L29P_0 D5 I/O0 IO_L21N_0 D6 I/O0 IO_L26N_0 D7 I/O0 IO_L22N_0 D9 I/O0 IO_L16N_0 D10 I/O0 IO_L09N_0 D13 I/O0 IO_L12P_0 D14 I/O0 IO_L08P_0 D15 I/O0 IP_0 D17 INPUT0 IP_0 D18 INPUT0 IO_L01P_0 D19 I/O0 IP_0 E6 INPUT0 IO_L31P_0/VREF_0 E7 VREF0 IO_L27N_0 E8 I/O0 IP_0 E10 INPUT0 IO_L19N_0/GCLK9 E11 GCLK0 IO_L17P_0/GCLK4 E12 GCLK0 IO_L09P_0 E13 I/O0 IO_L05P_0 E15 I/O0 IO_L04P_0 E16 I/O0 IP_0 E17 INPUT0 IO_L31N_0/PUDC_B F7 DUAL0 IO_L27P_0 F8 I/O0 IO_L23N_0 F9 I/OTable 63: Spartan-3A DSP CS484 Pinout (Cont’d)Bank Pin Name CS484Ball Type
