SRAM configuration elements allow APEX 20KC devices to be
reconfigured in-circuit by loading new configuration data into the device.
Real-time reconfiguration is performed by forcing the device into
command mode with a device pin, loading different configuration data,
reinitializing the device, and resuming user-mode operation. In-field
upgrades can be performed by distributing new configuration files.
Configuration Schemes
The configuration data for an APEX 20KC device can be loaded with one
of five configuration schemes (see
target application. An EPC16, EPC2, or EPC1 configuration device,
intelligent controller, or the JTAG port can be used to control the
configuration of an APEX 20KC device. When a configuration device is
used, the system can configure automatically at system power-up.
Multiple APEX 20KC devices can be configured in any of five
configuration schemes by connecting the configuration enable (nCE) and
configuration enable output (nCEO) pins on each device.
