Pin InformationTable 5–20. EPC2, EPC1 & EPC1441 Pin Functions During Configuration (Part 4 of 4)Pin Name8-PinPDIP (1)Pin Number20-PinPLCC32-PinTQFP (2)Pin TypeVCCSEL N/A 5 3 Input Mode select for V CC supply. VCCSEL must beconnected to ground if the device uses a 5.0-Vpower supply (VCC = 5.0 V). VCCSEL must beconnected to VCC if the device uses a 3.3-Vpower supply (V CC = 3.3 V).This pin is only available in EPC2 devices.VPPSEL N/A 14 17 Input Mode select for VPP. VPPSEL must beconnected to ground if VPP uses a 5.0-V powersupply(V PP = 5.0 V). VPPSEL must be connected toV CC if VPP uses a 3.3-V power supply (V PP = 3.3V).This pin is only available in EPC2 devices.VPP N/A 18 23 Power Programming power pin. For the EPC2 device,this pin is normally tied to VCC. If the EPC2 V CCis 3.3 V, VPP can be tied to 5.0 V to improve insystemprogramming times. For EPC1 andEPC1441 devices, VPP must be tied to V CC .This pin is only available in EPC2 devices.VCC 7, 8 20 27 Power Power pin.GND 5 10 12 Ground Ground pin. A 0.2-µF decoupling capacitor mustbe placed between the V CC and GND pins.Notes to Table 5–20:(1) This package is available for EPC1 and EPC1441 devices only.(2) This package is available for EPC2 and EPC1441 devices only.Description5–30 Altera CorporationConfiguration Handbook, Volume 2 April 2007
