Product details
Overview
MCF5212LCVM80J from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller operating at up to 80 MHz, featuring 256 KB flash, 32 KB SRAM, FlexCAN 2.0B, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four DMA-capable 32-bit timers, and integrated PLL clock generation - deployed in industrial motor control and embedded CAN-based automation systems.
For engineers reviewing the MCF5212LCVM80J datasheet, MCF5212LCVM80J pinout, MCF5212LCVM80J application, or MCF5212LCVM80J equivalent, key selection considerations include its LQFP-64 package, 80 MHz V2 ColdFire core with MAC unit, 76 MIPS Dhrystone performance, FlexCAN timing compliance up to 1 Mbps, and dual-S/H ADC architecture enabling simultaneous sampling for closed-loop control.
Technical Context
The MCF5212LCVM80J implements the ColdFire Version 2 core with static operation, 32-bit address/data paths, ISA_A+ instruction set, and a dedicated 32-bit MAC unit supporting 16×16→32 and 32×32→32 operations. Its on-chip PLL accepts 1–48 MHz crystal or 8 MHz internal relaxation oscillator input and generates system clocks up to 80 MHz with programmable pre-divider (1–8) and post-divider (2n, n ≤ 15).
It integrates a full FlexCAN 2.0B module with 16 configurable message buffers, programmable bit rate up to 1 Mbps, time-stamped receive/transmit, and global network time synchronization - alongside three UARTs with FIFOs, DMA support, and modem control lines (RTS/CTS), and an eight-channel 12-bit ADC with 1.125 µs minimum conversion time and simultaneous dual-channel sampling capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF5213CVM80 | Same V2 core, 80 MHz, 256 KB flash, 32 KB SRAM, but in 100-pin LQFP; adds full JTAG trace interface and extra GPIO. | Requires larger PCB footprint; supports real-time trace and additional peripherals (e.g., second CAN channel in some variants). | Select when full debug visibility or expanded I/O is required; not pin-compatible with MCF5212LCVM80J. |
| MCF52235CAG80 | Successor ColdFire V2 device with same core frequency but enhanced peripherals: USB OTG, Ethernet MAC, larger SRAM (64 KB), and improved ADC linearity. | Targets next-gen designs needing connectivity; lacks direct drop-in compatibility due to different pinout and memory map. | Choose for new designs requiring USB/Ethernet; migration from MCF5212LCVM80J requires PCB and firmware revision. |
Compared with MCF5212LCVM80J, the MCF5213CVM80 offers expanded debug capability and I/O count in a larger package, while the MCF52235CAG80 provides modern connectivity features at the cost of legacy pin compatibility - both require layout changes and firmware adaptation.

FAQ
What is the maximum clock frequency supported by the MCF5212LCVM80J?
The MCF5212LCVM80J supports a maximum core clock frequency of 80 MHz, achieved via its integrated PLL using an external 1–48 MHz crystal or the internal 8 MHz relaxation oscillator. At this frequency, it delivers 76 MIPS (Dhrystone 2.1) performance from on-chip flash memory, enabling hard real-time execution of control algorithms in the MCF5212LCVM80J.
Does the MCF5212LCVM80J include a CAN controller, and what version does it support?
Yes, the MCF5212LCVM80J integrates a FlexCAN 2.0B module compliant with ISO 11898-1, supporting standard and extended frames, programmable bit rates up to 1 Mbps, 16 configurable message buffers, and time-stamped transmit/receive. This makes the MCF5212LCVM80J suitable for automotive diagnostics and industrial distributed control networks requiring robust, deterministic messaging.
How many analog-to-digital converter (ADC) channels does the MCF5212LCVM80J have, and what is their resolution?
The MCF5212LCVM80J features an eight-channel, 12-bit fast ADC with simultaneous dual-channel sampling capability enabled by two independent sample-and-hold circuits. Minimum conversion time is 1.125 µs, and it supports interrupt generation on limit violations or zero crossings - critical for real-time feedback in the MCF5212LCVM80J's motor control applications.
What debug interfaces are available on the MCF5212LCVM80J?
The MCF5212LCVM80J provides Background Debug Mode (BDM) via dedicated DSI/DSO/DSCLK pins and the ALLPST signal for halted-state detection. It does not include full JTAG trace capability - that feature is reserved for 100-pin packages like the MCF5213CVM80. The MCF5212LCVM80J's debug interface supports real-time in-circuit debugging without external emulators.
Is the MCF5212LCVM80J pin-compatible with other members of the MCF521x family?
No, the MCF5212LCVM80J in LQFP-64 is not pin-compatible with MCF5213 variants in 100-pin LQFP or MAPBGA packages. While functional overlap exists (same core, memory, and peripheral sets), pin assignments differ significantly across packages. Migration to MCF5213CVM80 requires PCB redesign due to incompatible pinout and added debug signals - the MCF5212LCVM80J remains a standalone LQFP-64 solution.
