Device identity and production status
The Renesas HD407L4808FS is a 4-bit OTPROM microcontroller built on the HMCS400 CPU core — a legacy architecture for cost-sensitive, low-pin-count embedded control where code is fixed at manufacture and never field-updated. Production status is Active per the manufacturer's lifecycle record, so the part remains in the current portfolio for new builds and replacement orders.
Compliance and package note
RoHS non-compliant — the part does not meet the Restriction of Hazardous Substances directive, which matters for any BOM that must ship into EU or similar regulated markets without an exemption. Supplied in Bulk package form, meaning the devices are shipped loose in tubes or trays rather than tape-and-reel — a factor for pick-and-place lines that expect reeled input.
