Product Overview
The Megawin MPC89L515AF is an 8-bit microcontroller built around the standard 80C51 core, housed in a surface-mount 44-lead low-profile quad flat package (LQFP-44). Designed for low-power and low-voltage applications, it operates on 2.4V to 3.6V supplies and provides 63 KB of on-chip ISP/IAP Flash program memory alongside 1,280 bytes of total RAM. It serves as a direct drop-in replacement or core build component for legacy industrial controls, communications boards, and embedded systems requiring standard 8051 code execution with expanded Flash headroom.
Key Features
- 8-bit 80C51 instruction-set-compatible processing core
- 63 KB on-chip Flash memory with In-System Programming (ISP) and In-Application Programming (IAP)
- 1,280 bytes total RAM (256 bytes standard internal RAM plus 1,024 bytes auxiliary on-chip RAM)
- Operating voltage range: 2.4V to 3.6V
- Three 16-bit timer/counters (Timer 0, Timer 1, Timer 2)
- Up to 36 general-purpose I/O pins across standard 8-bit ports and Port 4
- Enhanced full-duplex hardware UART and 15-bit watchdog timer
- 44-lead Low-Profile Quad Flat Package (LQFP-44) surface-mount footprint
Applications
- Replacing damaged or corrupted microcontrollers on legacy industrial machinery control boards.
- Maintaining dedicated automation hardware without rewriting tested 8051 firmware routines.
- Prototyping custom retro-computing peripherals and low-voltage embedded projects on breadboard breakout adapters.
Frequently Asked Questions
What is the pin count and package type for this microcontroller?
This chip is packaged in a 44-lead Low-Profile Quad Flat Package (LQFP-44) with 11 gull-wing pins along each of its four edges.
What operating voltage does the MPC89L515AF require?
The device operates within a 2.4V to 3.6V DC range, with a minimum of 2.7V recommended during In-System Programming Flash write operations.
Why buy individual microcontrollers here instead of a full factory reel?
Repairing field equipment and bench testing rarely demand an entire production reel of obsolete chips. Purchasing verified, photographed parts by the piece lets you fix the hardware in front of you without tying up cash in dead stock. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship flat-rate for $8, upgrade to free shipping once your cart reaches $28, and dispatch from our Idaho warehouse the same or next business day.
Solid 8051 architecture never really retires as long as there is legacy industrial iron running on its clock. Solder this down, load your hex file, and get that control board back online.
