EPC2LC20

Functional Description

With SRAM-based devices, configuration data must be reloaded each time the device powers up, the system initializes, or when new configuration data is needed. Altera configuration devices store configuration data for SRAM-based ACEX 1K, APEX 20K, APEX II, Arria GX, Cyclone, Cyclone II, FLEX 10K, FLEX 6000, Mercury, Stratix, Stratix GX, Stratix II, and Stratix II GX devices.

Features

Configuration devices for SRAM-based LUT devices offer the following features:
■ Configures Altera ACEX® 1K, APEX® 20K (including APEX 20K, APEX 20KC, and APEX 20KE), APEX II, Arria® GX, Cyclone®, Cyclone II, FLEX® 10K (including FLEX 10KE and FLEX 10KA) Mercury®, Stratix®, Stratix GX, Stratix II, and Stratix II GX devices
