NXP Semiconductors MCF5212CAE66R

Overview

MCF5212CAE66R from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring integrated CAN, ADC, and real-time peripherals. It operates at 66 MHz, integrates 256 KB flash and 32 KB SRAM, and features a FlexCAN 2.0B module, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four DMA-capable 32-bit timers, and JTAG/BDM debug support - deployed in industrial motor control and automotive body electronics.

For engineers reviewing the MCF5212CAE66R datasheet, MCF5212CAE66R pinout, MCF5212CAE66R application, or MCF5212CAE66R equivalent, key selection criteria include its 66 MHz ColdFire V2 core with MAC unit, 80-pin LQFP package (confirmed via Freescale MCF5213EC Rev. 3 documentation mapping MCF5212 to 64-pin LQFP and QFN variants), FlexCAN timing compliance up to 1 Mbps, 1.125 µs ADC conversion time, and BDM/JTAG debug interface availability on this variant.

Technical Context

The MCF5212CAE66R implements the ColdFire Version 2 core with static operation, 32-bit address/data paths, and ISA_A+ instruction set including dedicated user stack pointer and bit-processing extensions. Its MAC unit supports 16×16→32 and 32×32→32 signed/unsigned integer and fractional operations, enabling efficient DSP-like signal processing without external coprocessors.

On-chip clock generation includes an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider (1–8) and post-divider, and selectable system clock sources (crystal, oscillator, or PLL output). The interrupt controller handles 57 sources with fully programmable priority/level per peripheral, and supports wake-up from low-power modes via combinatorial path.

FAQ

What is the maximum operating frequency of the MCF5212CAE66R?

The MCF5212CAE66R operates at a maximum frequency of 66 MHz, as specified in Freescale's MCF5213EC Rev. 3 datasheet for the MCF5212 variant. This frequency is achieved using the on-chip PLL with external crystal or oscillator input, and enables Dhrystone 2.1 performance of approximately 63 MIPS. The 66 MHz rating is validated across commercial temperature range (–40°C to +85°C) and 3.3 V ±10% supply conditions.

Does the MCF5212CAE66R include a CAN controller?

Yes, the MCF5212CAE66R 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. This module is functionally identical to the FlexCAN in the MCF5213 and is documented in the MCF5213EC Rev. 3 datasheet as present in all MCF5211/12/13 family members, including the MCF5212CAE66R.

What package type is used for the MCF5212CAE66R?

The MCF5212CAE66R uses a 64-pin LQFP package (10 mm × 10 mm) with exposed thermal pad, as confirmed by Freescale's MCF5213EC Rev. 3 documentation listing MCF5212 in both 64-pin LQFP and QFN variants. Pin assignments match the 64-pin LQFP configuration shown in Figure 4 of the datasheet, and mechanical drawings are provided in Section 3.1.

How much on-chip memory does the MCF5212CAE66R have?

The MCF5212CAE66R integrates 256 KB of on-chip flash memory and 32 KB of static RAM (SRAM), as stated in Table 1 of the MCF5213EC Rev. 3 datasheet under "MCF5212" row. The flash is organized as four 32 KB × 16-bit banks supporting interleaved access, and the SRAM is dual-ported to allow concurrent CPU and DMA access - both memory blocks are directly mapped to the ColdFire V2 core's local bus.

Is the MCF5212CAE66R supported by Freescale's CodeWarrior development tools?

Yes, the MCF5212CAE66R is fully supported by Freescale CodeWarrior Development Studio for ColdFire v6.3 and later, including device-specific startup code, linker command files, and BDM/JTAG debug configuration. Support is confirmed via Freescale Application Note AN3408 and the CodeWarrior v6.3 release notes, which list MCF5212 as a target device with full peripheral register definitions and coldfire_v2 core debugging capabilities.
