Configuration Devices
Altera^® serial configuration devices support a single-device and multi-device
configuration solution for Stratix IV devices and are used in the fast AS configuration
scheme. Serial configuration devices offer a low-cost, low pin-count configuration
solution.
f For information about serial configuration devices, refer to the Serial Configuration
Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Data Sheet in volume 2 of the
Configuration Handbook.
1 All minimum timing information in this chapter covers the entire Stratix IV family.
Some devices may work at less than the minimum timing stated in this handbook due
to process variation.
Configuration Schemes
Select the configuration scheme by driving the Stratix IV device MSEL pins either high
or low, as shown in Table 10–1. The MSEL input buffers are powered by the V_CC power
supply. Altera recommends hard wiring the MSEL[] pins to V_CCPGM and GND. The
MSEL[2..0] pins have 5-k internal pull-down resistors that are always active.
During power-on reset (POR) and during reconfiguration, the MSEL pins must be at
V_IL and V_IH levels of V_CCPGM voltage to be considered logic low and logic high.
1 To avoid problems with detecting an incorrect configuration scheme, hardwire the
MSEL[] pins to V_CCPGM and GND without pull-up or pull-down resistors. Do not drive
the MSEL[] pins by a microprocessor or another device.
