4-bit OTPROM MCU for cost-sensitive embedded control
The HD4074408S is a 4-bit microcontroller with one-time programmable (OTPROM) memory, running at a 9 MHz clock. This places it in the class of low-pin-count, low-cost controllers used for simple logic, timing, and interface tasks in appliances, toys, and basic industrial controls — applications where reprogrammability is not required and the firmware is fixed at the factory.
Bulk packaging — standard for through-hole assembly
The HD4074408S ships in Bulk packaging, which is the standard format for through-hole devices handled in tube or tray. For a contract manufacturer, this means the part is compatible with traditional wave-solder and hand-assembly lines — no tape-and-reel feeding required, though pick-and-place for through-hole is typically manual or semi-automated.
Sourcing and compliance for the BOM line
As an active Renesas Electronics part, the HD4074408S can be sourced through authorized distribution and independent channels. Compliance documentation (RoHS, REACH) should be available from Renesas upon request, though the evidence does not list specific certifications for this order code. The part falls under the Discrete Semiconductors category, which typically includes bare die or packaged logic and memory devices.
