Product details

Active 4-bit OTPROM MCU — still in current manufacture

The HD4074019FS: This is a one-time-programmable device — firmware is written during manufacturing and cannot be field-updated, which suits high-volume, firmware-locked embedded applications where code stability is guaranteed before mask.

Bulk packaging and supply posture

Supplied in Bulk format, the HD4074019FS is suited for production-line pick-and-place or through-hole assembly in moderate to high volumes.

Frequently asked questions

What is HD4074019FS's memory type and what does that mean for firmware updates?

The HD4074019FS uses OTPROM (one-time programmable read-only memory). The program is written during device programming and cannot be erased or rewritten — firmware must be finalized before production.

Who supplies HD4074019FS and how is it quoted for volume purchases?

Renesas Electronics is the manufacturer.
