OTPROM means the program memory is written once during manufacturing — field firmware updates are not possible, so this part fits production code that is locked at the factory and never revised.","metaTitle":"HD4074618H Renesas 4-Bit OTPROM MCU, Active","metaDescription":"HD4074618H 4-bit OTPROM microcontroller from Renesas Electronics, active production.
