FLEX 10K Embedded Programmable Logic Device Family Data Sheet

SRAM configuration elements allow FLEX 10K 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.

The entire reconfiguration process may be completed in less than 320 ms

using an EPF10K250A device with a DCLK frequency of 10 MHz. This

process can be used to reconfigure an entire system dynamically. In-field

upgrades can be performed by distributing new configuration files.

Refer to the configuration device data sheet to obtain the POR

delay when using a configuration device method.

Programming Files

Despite being function- and pin-compatible, FLEX 10KA and FLEX 10KE

devices are not programming- or configuration-file compatible with

FLEX 10K devices. A design should be recompiled before it is transferred

from a FLEX 10K device to an equivalent FLEX 10KA or FLEX 10KE

device. This recompilation should be performed to create a new

programming or configuration file and to check design timing on the

faster FLEX 10KA or FLEX 10KE device. The programming or

configuration files for EPF10K50 devices can program or configure an

EPF10K50V device. However, Altera recommends recompiling a design

for the EPF10K50V device when transferring it from the EPF10K50 device.

Configuration Schemes

The configuration data for a FLEX 10K device can be loaded with one of

five configuration schemes (see Table 116), chosen on the basis of the

target application. An EPC1, EPC2, EPC16, or EPC1441 configuration

device, intelligent controller, or the JTAG port can be used to control the

configuration of a FLEX 10K device, allowing automatic configuration on

system power-up.
