Product Overview
Unused Microchip PIC16C65A 8-Bit Microcontroller in a 40-Pin Plastic DIP
Condition
New, unused new old stock. The photos show a clean matte black 40-pin plastic dual inline package with the top surface marked PIC16C65A-04/P over 9739SBW, alongside the Microchip logo. Leads are straight, bright, and full length, with no solder, flux, or board residue on the tips and no bent or clipped pins. The piece is shown resting on pink anti-static bubble wrap. Per the original listing, this is unused new old stock pulled from a Furon pump controller module that was never put into service.
Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense.

Product Overview
The PIC16C65A-04/P is an 8-bit CMOS microcontroller from Microchip Technology's PIC16C6x family, supplied here in the through-hole 40-pin plastic DIP that the /P suffix denotes. The top of the package reads PIC16C65A-04/P on the first line and 9739SBW on the second, so the part number and factory lot marking are both legible in the photos rather than taken on faith. Parts in the C series that ship in a plain plastic body carry no erase window, so treat the program memory as one-time programmable and confirm the exact memory, speed grade, and peripheral set against the Microchip datasheet before you design it in. These are the microcontrollers that ran industrial control boards through the late 1990s, and boards like that are still in service and still need matching silicon. Five pieces are on hand, so you can take one for a single repair or several as shelf spares.
Key Features
- Part number: PIC16C65A-04/P, printed on the package and readable in both photos
- Manufacturer: Microchip Technology, logo printed in white ink on the top surface
- Lot marking: 9739SBW on the second line
- Package: 40-pin plastic dual inline package, through-hole, /P suffix
- Family: PIC16C6x 8-bit CMOS microcontroller
- Program memory: C series in a plain plastic body has no erase window, so treat it as one-time programmable and verify against the datasheet before use
- Speed grade, memory size, and peripheral set: not confirmed here, verify against the Microchip datasheet before use
- Leads: straight, bright, and full length with no solder or board residue visible
- Condition: unused new old stock, pulled from a pump controller module that was never put into service
- Quantity available: five pieces
Applications
- Maintenance technician rebuilding a 1990s industrial pump or process controller that was designed around a socketed PIC16C6x
- Repair shop matching the original board build on a legacy control card rather than redesigning around a modern part
- Instrument owner stocking shelf spares for a machine whose controller board is no longer supported by its maker
- Embedded developer keeping a through-hole PIC16C6x on the bench for socketed prototype work and firmware archaeology
Frequently Asked Questions
What exactly is printed on the chip?
Two lines and a logo. The first line reads PIC16C65A-04/P, the second reads 9739SBW, and the Microchip name and logo sit below them. Both photos show the marking, so you can confirm it against your own board before ordering.
Is the program memory blank?
Not confirmed. We have not read this device, and the C series in a plain plastic body has no erase window, so any contents cannot be cleared. If a blank part matters for your build, read and verify it in a programmer before you commit it to a board.
Where did these come from?
They were pulled from a Furon pump controller module that was never put into service, so they are unused rather than field returns. The photos back that up: leads are straight and bright, with no solder wicked onto the tips and no board residue between the pins.
Will it drop into my existing socket?
The body is a 40-pin plastic DIP on standard through-hole spacing, which is the footprint these boards were built around. Pinout and electrical compatibility with whatever is currently in the socket are not confirmed by us, so check both against the Microchip datasheet and your board documentation first.
I only need one or two. Do I have to buy a tube of them?
No. Five pieces are on hand and you buy the count you actually need, whether that is a single chip to finish one repair or a few to put on the spares shelf. Shipping is a flat $8, free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Built for a Furon pump controller that never ran a single cycle, this one sat out its whole first career in anti-static wrap. Drop it into the board that needs it and let it finally go to work.
