Megawin MPC89L515AF 8051 8-Bit Microcontroller LQFP-44 New Surplus

Megawin MPC89L515AF 8051-Compatible 8-Bit Microcontroller in a Fine-Pitch LQFP

Condition

New. The photographed piece is a black epoxy LQFP surface-mount microcontroller, laser-marked below the Megawin logo with three lines: MPC89L515AF, then 0632TG8DA, then CT48999 000. Leads are bright, straight, and even on all four sides, with no solder on the tips, no bent or splayed pins, and no oxidation or board residue. The leading digits of the lot line are consistent with a mid-2000s production run, but treat the lot code as a reference and not a guarantee. Stock is deep at the time of writing, 186 pieces on hand, and we sell them loose in whatever count you ask for rather than by the reel.

Same or next business day shipping from our Idaho warehouse. Honest pricing, no nonsense.

Product Overview

This is a Megawin 8-bit microcontroller from the MPC89 line, an 8051-core family, so the instruction set and general architecture will be familiar to anyone who has worked with 80C51 derivatives. The body of this unit is marked MPC89L515AF, which is the identifier to search and to check against the Megawin datasheet. It arrives in a surface-mount quad flat pack with gull-wing leads on all four sides, eleven per side as counted in the photo, so it is a board-mount part rather than a socketed DIP. Flash size, RAM, clock rate, operating voltage, and peripheral set are not confirmed here. Verify them against the datasheet for the exact marked part number before you design it in or drop it onto a repair.

Key Features

• Brand: Megawin, logo and name laser-marked on the package
• Part marking: MPC89L515AF, read directly from the body of the photographed unit
• Family: MPC89 series, 8051-core 8-bit microcontroller
• Package: LQFP surface mount, gull-wing leads on all four sides, eleven per side counted in the photo
• Secondary markings: 0632TG8DA and CT48999 000, lot and traceability lines
• Condition: New, unused surplus stock
• Availability: 186 pieces on hand at the time of writing, sold in the exact quantity you need
• Flash, RAM, clock speed, and supply voltage: Not confirmed - verify against the Megawin datasheet before use

Applications

• Firmware developer keeping a legacy 8051 product in production and needing the same Megawin silicon the original build used
• Repair technician replacing a lifted or cooked microcontroller on a board that already carries a Megawin MPC89 part
• Prototyper hand-soldering an LQFP onto a breakout board to bring up an 8051 project without ordering a full reel
• Electronics instructor or lab stocking a few spare 8051-class microcontrollers for student builds and bench experiments

Frequently Asked Questions

What exactly is printed on the chip?

Four lines. The Megawin logo and name across the top, then MPC89L515AF, then 0632TG8DA, then CT48999 000. The marking is low-contrast laser etch on black epoxy, which is normal for this package, and it photographs better under angled light than straight on.

How much flash and RAM does this part have, and what clock will it run?

Not confirmed here. We list what is printed on the part and what we can see. Pull the Megawin datasheet for the marked part number and confirm memory, clock, and pinout against your board before committing.

Has this piece been tested or programmed?

No test result is published for this listing. It is sold as new unused surplus in the condition described above, and we make no claim about the state of the on-chip memory. If your build needs a verified device, plan to check it on arrival.

Do I need special tools to solder an LQFP like this?

It is a fine-pitch surface-mount package, so hot air, a stencil and reflow, or careful drag soldering with flux and wick all work. It will not go into a DIP socket. If you want to bench-test one first, an LQFP to DIP breakout board makes that straightforward.

Why buy one or two of these instead of a bulk lot from a big marketplace?

Because a repair or a prototype usually needs two microcontrollers, not fifty. PartsMine sells the exact count you ask for out of the 186 on hand, shipping is $8 flat rate and free over $28, and orders go out the same or next business day from Idaho. For a small handful of parts that lands well under the cost of a forced-quantity reel or tray.

Long after Intel moved on, the 8051 core kept running the quiet machines nobody thinks about, and Megawin kept building the silicon that speaks it. If your board still wants that instruction set in a fine-pitch package, this one has been waiting in a bin in Idaho for the call.
