- The EPC2 and EPC16 configuration devices are Flash-based devices and can be reprogrammed at least 100 times.
- The EPC1, EPC1441, EPC1213, and EPC1064 configuration devices are one-time programmable.
Altera guarantees you can reprogram windowed EPROM-based devices at least 25 times.
Altera does not specify the number of times you can reprogram or reconfigure FPGA devices because these devices are SRAM-based. An SRAM-based device can be reconfigured as often as a design requires; there is no specific limit.
Additional device reliability information is available in the Altera Reliability Report (PDF).
