NXP Semiconductors MCF52212AE50

Overview

MCF52212AE50 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring deterministic real-time response, integrated analog acquisition, and USB connectivity. It operates at 50 MHz, integrates 64 KB flash and 8 KB SRAM, features an 8-channel 12-bit ADC with simultaneous sampling, three UARTs, two I²C modules, QSPI, USB OTG controller, and four 32-bit DMA-capable timers - deployed in industrial motor control, portable instrumentation, and USB-enabled HMI systems.

For engineers reviewing the MCF52212AE50 datasheet, MCF52212AE50 pinout, MCF52212AE50 application, or MCF52212AE50 equivalent, key selection considerations include its 50 MHz V2 ColdFire core performance (46 MIPS Dhrystone), 64-pin LQFP package with 46 GPIO, USB OTG dual-mode support, and family-specific peripheral configuration versus MCF52211/MCF52213 variants.

Technical Context

The MCF52212AE50 implements the ColdFire V2 ISA_A+ instruction set with MAC unit and hardware divider, executing at 50 MHz with static operation and full 32-bit address/data paths. Its clock system combines an on-chip 8 MHz relaxation oscillator, external crystal input, and PLL with programmable dividers to generate system clocks while supporting low-power sleep and stop modes.

Peripheral integration includes a dedicated 8-channel 12-bit ADC with dual sample-and-hold for simultaneous conversion, four independent 32-bit DTIM timers with input capture/output compare and DMA trigger capability, and a USB OTG controller compliant with USB 1.1/2.0 full-speed/low-speed operation - all mapped to a fixed memory-mapped I/O space accessible via the local bus.

FAQ

What is the maximum operating frequency of the MCF52212AE50?

The MCF52212AE50 operates at a maximum frequency of 50 MHz, delivering 46 MIPS (Dhrystone 2.1) performance. This speed is fixed by factory configuration and cannot be overclocked. The V2 ColdFire core maintains full static operation, allowing it to halt at any clock phase without losing state - essential for low-power and deterministic real-time applications. The MCF52212AE50 achieves this frequency using either the internal 8 MHz relaxation oscillator with PLL multiplication or an external crystal source.

Does the MCF52212AE50 support USB device and host modes simultaneously?

Yes, the MCF52212AE50 integrates a USB On-The-Go (OTG) controller that supports both full-speed/low-speed device and host roles. It implements the USB OTG supplement to the USB specification, enabling peer-to-peer communication without a PC host. The MCF52212AE50 uses a single USB_DP/USB_DM differential pair and detects role via ID pin state or software configuration. Its 16 bidirectional endpoints and DMA/FIFO interface allow concurrent handling of multiple USB transactions in either mode.

How many analog input channels does the MCF52212AE50 ADC support, and what is its resolution?

The MCF52212AE50 features an 8-channel, 12-bit analog-to-digital converter (ADC) with a minimum conversion time of 1.125 µs. It includes two independent sample-and-hold circuits, enabling true simultaneous sampling of two channels - critical for vector-controlled motor drives. Unused ADC inputs can be repurposed as digital I/O. The ADC supports single-scan, triggered, or continuous operation, with optional interrupts on completion, zero crossing, or out-of-range conditions - all configurable in the MCF52212AE50's ADC control registers.

What package type and pin count does the MCF52212AE50 use?

The MCF52212AE50 is supplied in a 64-pin LQFP package measuring 10 mm × 10 mm with 0.5 mm pitch and an exposed thermal pad. This package provides 46 general-purpose I/O pins, multiplexed across UART, I²C, QSPI, ADC, PWM, and timer functions. Pin assignments match the MCF52211/MCF52212 family documentation, and mechanical drawings are specified in Freescale document MCF52211 Rev. 2, Section 3.1. The LQFP-64 variant is pin-compatible across the MCF5221x family for shared PCB design.

Does the MCF52212AE50 include hardware debug support, and what interface is used?

Yes, the MCF52212AE50 includes Background Debug Mode (BDM) support via a dedicated 3-wire debug serial interface (DSI, DSO, DSCLK) and the ALLPST signal - available on all package variants including the 64-pin LQFP. This enables in-circuit debugging, real-time trace, and breakpoint control without requiring JTAG pins or the full 100-pin package. The MCF52212AE50 implements ColdFire Debug Architecture Revision B+, supporting up to six hardware breakpoints and real-time interrupt servicing during debug sessions - fully documented in the MCF52212AE50 reference manual.
