4-bit OTPROM microcontroller in active production
The HD4074344FP is a 4-bit microcontroller from Renesas Electronics with on-chip OTPROM program memory, targeting embedded control applications that require a one-time-programmable code store.
Package and procurement fit
Supplied in Bulk packaging, the HD4074344FP ships as loose units rather than tape-and-reel, which suits low-volume production runs, prototyping, or hand-assembly where a reel feed is not required. As a 4-bit OTPROM device, the firmware is programmed at the factory or during a one-time programming step — field updates are not possible, so the code must be finalised before the programming event.
