IntroductionfFor information on enhanced configuration devices, refer to the EnhancedConfiguration Devices (EPC4, EPC8 and EPC16) Data Sheet and the UsingAltera Enhanced Configuration Devices chapters in volume 2 of theConfiguration Handbook.1 The largest enhanced configuration device supports 16 MBits ofconfiguration bitstream. You may need to use the MAX IIdevice, or use a microprocessor using a flash memoryconfiguration method, or use the compression feature, to reducethe configuration file size of large Stratix III devices.The Altera serial configuration devices (EPCS128, EPCS64, and EPCS16)support a single-device configuration solution for Stratix III devices andare used in the fast AS configuration scheme. Serial configuration devicesoffer a low-cost, low-pin count configuration solution.fFor information on serial configuration devices, refer to the SerialConfiguration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128)Data Sheet in volume 2 of the Configuration Handbook.1 The largest serial configuration device currently supports64 MBits of configuration bitstream.Configuration SchemesSelect the configuration scheme by driving the Stratix III device MSELpins either high or low, as shown in Table 11–1. The MSEL pins arepowered by the V CCPGM power supply of the bank they reside in. TheMSEL[2..0] pins have 5-kΩ internal pull-down resistors that are alwaysactive. During power-on reset (POR) and during reconfiguration, theMSEL pins have to be at LVTTL V IL and V IH levels to be considered a logiclow and logic high.1 To avoid any problems with detecting an incorrect configurationscheme, hard-wire the MSEL[] pins to V CCPGM and GND,without any pull-up or pull-down resistors. Do not drive theMSEL[] pins by a microprocessor or another device.Table 11–1.
