概述

Description

The MCF5249LAG120 is a Freescale/NXP ColdFire 32‑bit microcontroller in the MCF5249 family. It uses a ColdFire V2 32‑bit RISC core and targets embedded control applications. The “LAG120” suffix indicates a leaded LQFP‑120 package.
Key points:
- Core: ColdFire V2 32‑bit CPU suitable for mid‑range embedded tasks.
- Peripherals: Ethernet MAC (10/100) for networking, multiple serial ports (UARTs), I2C, SPI, timers, PWM, and ADCs.
- Memory/IO: On‑chip options plus external memory interface for Flash/RAM; pin‑compatible I/O for diverse applications.
- Package: LQFP‑120 (120‑pin) family variant.
- Applications: Industrial automation, embedded control with networking/connectivity requirements.
For exact specifications (clock speed, memory sizes, pinout, electrical characteristics), consult the MCF5249 data sheet and user manual. Development resources include official Freescale/NXP documentation, application notes, and supported toolchains. If you want, I can pull out the precise features for a specific revision.

Features
