Most SRAM-based FPGAs provide an optional serial sequential interface to configure the device. Most of the serial PROMs listed are functionally equivalent, with a few exceptions. For example, the Altera FLEX 10K requires a special mode supported only by Altera and Atmel. Also, be forewarned that different vendors have different power-on and reset capabilities.

Most serial configuration PROMs use EPROM technology in plastic packaging, making them one-time-programmable (OTP) devices. The major exception is Atmel, with E²PROM-based devices offering 5-volt, in-system programming capabilities.

The latest generation of FPGAs also support commodity SPI Flash PROMs.
