NXP Semiconductors MCF5212LCVM80

Overview

MCF5212LCVM80 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring integrated CAN, high-resolution ADC, and deterministic real-time peripherals. It operates at up to 80 MHz, integrates 256 KB flash and 32 KB SRAM, and features FlexCAN 2.0B, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four 32-bit DMA timers, and programmable PWM - deployed in industrial motor drives and automotive body control modules.

For engineers reviewing the MCF5212LCVM80 datasheet, MCF5212LCVM80 pinout, MCF5212LCVM80 application, or MCF5212LCVM80 equivalent, key selection considerations include its LQFP-64 package, 80 MHz V2 ColdFire core with MAC unit, FlexCAN timing compliance up to 1 Mbps, 1.125 µs ADC conversion time, and BDM/JTAG debug support with reduced trace capability.

Technical Context

The MCF5212LCVM80 implements the ColdFire Version 2 core with dual-pipeline architecture (IFP/OEP), ISA_A+ instruction set, and hardware MAC unit supporting 16×16→32 and 32×32→32 operations. Its clock system combines an on-chip 8 MHz relaxation oscillator, external crystal input (1–48 MHz), and PLL with programmable pre-divider (1–8) and post-divider (2ⁿ, n ≤ 15).

Peripheral integration follows tightly coupled memory-mapped architecture: FlexCAN uses dedicated message buffers (16 total, configurable Rx/Tx), the 12-bit ADC supports simultaneous two-channel sampling via dual S/H circuits, and the four DTIM modules provide 12.5 ns resolution at 80 MHz with input capture/output compare and DMA trigger capability.

FAQ

What is the maximum operating frequency of the MCF5212LCVM80?

The MCF5212LCVM80 operates at a maximum frequency of 80 MHz, delivering 76 MIPS (Dhrystone 2.1) when running from internal flash memory. This speed is achieved using the ColdFire V2 core with integrated multiply-accumulate (MAC) unit and hardware divider, enabling high-performance real-time control without external acceleration. The MCF5212LCVM80 achieves this frequency via its on-chip PLL, which accepts reference clocks from 1–48 MHz crystals or the internal 8 MHz relaxation oscillator.

Does the MCF5212LCVM80 support CAN 2.0B communication?

Yes, the MCF5212LCVM80 integrates a FlexCAN 2.0B module compliant with ISO 11898-1, supporting standard and extended frames, programmable bit rates up to 1 Mbps, and 16 configurable message buffers. It implements full CAN protocol features including listen-only mode, content-related addressing, and global network time synchronization. The MCF5212LCVM80 uses dedicated CANRX/CANTX pins in its LQFP-64 package and requires an external CAN transceiver for physical layer interfacing.

What ADC capabilities does the MCF5212LCVM80 provide?

The MCF5212LCVM80 features an eight-channel, 12-bit fast analog-to-digital converter with a minimum conversion time of 1.125 µs and simultaneous dual-channel sampling capability via two independent sample-and-hold circuits. It supports single-scan, triggered, or continuous operation modes, with optional interrupts on conversion completion, zero crossing, or out-of-range conditions. Unused analog channels can be repurposed as digital I/O, and the MCF5212LCVM80 provides dedicated VRH/VRL reference pins for ratiometric measurements.

Which debug interfaces are supported by the MCF5212LCVM80?

The MCF5212LCVM80 supports Background Debug Mode (BDM) and IEEE 1149.1 JTAG boundary scan. While full real-time trace capability is limited to 100-pin packages, the MCF5212LCVM80 retains BDM serial communication (DSI/DSO/DSCLK) and the ALLPST debug signal for halted-state detection. It includes six hardware breakpoints (four PC, one address, one data), programmable trigger logic, and supervisor-mode debug register access - enabling in-circuit debugging without emulator hardware.

What package type and pin count does the MCF5212LCVM80 use?

The MCF5212LCVM80 is packaged in a 64-pin LQFP (Low-Profile Quad Flat Package) with 10 mm × 10 mm body size and 0.5 mm lead pitch. This package includes thermal enhancement via an exposed pad and is validated per Freescale's MCF5213EC Rev. 3 mechanical drawings. Pin assignments match the 64 LQFP variant described in Figure 4 and Table 3 of the datasheet, confirming compatibility with existing ColdFire V2 LQFP-64 footprints and layout guidelines.
