Microchip and Renesas MCU Surplus: Suffixes and Programming Status

Group Microchip PIC, AVR or dsPIC and Renesas RA, RX or RL78 stock by family, then provide complete ordering codes, packaging lots and use or programming history. A family name does not identify an exact device.

Distinguish families from ordering codes

Manufacturer family pages identify scope; complete suffixes identify actual package, grade or packing choices. Photograph discrepancies between labels and lists. Do not treat Microchip and Renesas devices as interchangeable.

Disclose programming and protection

Separate documented unused stock, programmed devices, mounted parts and unknown protection. Mark missing history as unknown; a past new-stock description is not sufficient after engineering use.

Split old-project and dispersed lots

Split the same code across lots, locations and packaging conditions. State which source documents match which batch. Start with a list stripped of unrelated customer information and agree further evidence and confidentiality.

Obtain written scope

Confirm accepted parts and counts, condition, inspection and deductions, freight, acceptance period and payment recipient. Examples are not a live purchasing list; each lot needs review against current requirements and available evidence.

Manufacturer references and scope

These references identify product families and public guidance. They do not establish our authorization, certification or testing capability.
