Does Intel offer write-once FPGA or an equivalent product?

April 1st, right?

A write once FPGA is basically called an ASIC. And yes, Intel does ASICs...

Write once (antifuse based) FPGA or CPLD devices are not very common anymore.

Intel/Altera does offer devices (MAX, MAX2, MAX5, MAX10 series for example) that store the configuration in internal EEPROM cells so they are basically instant on, and don't need to load a configuration serially from an external EEPROM device.

They are not write once, they can be reprogrammed hundreds of times. They do offer security fuse protection to prevent readback.

eASIC is an option but I'm not sure if it's still going or not: https://www.intel.com/content/www/us/en/products/details/easic.html

Hello,

e-ASIC products is not recommended for new design as this product will be phased out soon.

Apart from that, we only have FPGA product line ups, where users can write and re-write multiple times.

If you want to freeze your design after write it once, there is an option by implementing design encryption.

Hope this option can help you to make decision.
