APEX 20K Programmable Logic Device Family Data Sheet
SRAM configuration elements allow APEX 20K 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 20K device can be loaded with one of
five configuration schemes (see Table 115), chosen on the basis of the
target application. An EPC2 or EPC16 configuration device, intelligent
controller, or the JTAG port can be used to control the configuration of an
APEX 20K device. When a configuration device is used, the system can
configure automatically at system power-up.
Multiple APEX 20K 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.
