NXP Semiconductors MCF52212CAE50

Overview

MCF52212CAE50 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring integrated peripherals, deterministic real-time response, and low-power operation. It features a 50 MHz ColdFire core delivering 46 MIPS (Dhrystone 2.1), 64 KB flash memory, 8 KB SRAM, USB OTG controller, dual I²C interfaces, three UARTs, 8-channel 12-bit ADC, and four 32-bit DMA-capable timers - deployed in industrial motor control, portable instrumentation, and USB-enabled HMI systems.

For engineers reviewing the MCF52212CAE50 datasheet, MCF52212CAE50 pinout, MCF52212CAE50 application, or MCF52212CAE50 equivalent, key selection considerations include its 64-pin LQFP package, 50 MHz system clock rating, USB OTG dual-mode capability, 12-bit ADC with simultaneous sampling, and ColdFire V2 ISA_A+ instruction set support for efficient bit manipulation and DSP-like operations.

Technical Context

The MCF52212CAE50 implements the ColdFire Version 2 core with MAC unit and hardware divider, executing ISA_A+ instructions including dedicated bit-processing extensions. Its clock subsystem integrates an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider, and selectable clock sources (crystal, OCO, or external), enabling flexible low-power mode configuration with 2ⁿ dividers (n = 0–15).

Peripheral integration includes a full-featured USB OTG controller supporting host/device roles with 16 bidirectional endpoints and DMA/FIFO data paths; two independent I²C modules compliant with industry-standard timing; and a queued SPI (QSPI) master-only interface supporting up to 16 pre-programmed transfers at rates up to half the CPU clock frequency.

FAQ

What is the maximum operating frequency of the MCF52212CAE50?

The MCF52212CAE50 operates at a maximum system clock frequency of 50 MHz. This rating is specified in the Freescale MCF52211 datasheet (Rev. 2, March 2011), which covers the entire MCF5221x family including MCF52212CAE50. At this frequency, the ColdFire V2 core delivers 46 MIPS (Dhrystone 2.1) performance when executing from internal flash memory. The device supports lower-frequency operation via its programmable 2ⁿ divider (n = 0–15) for ultra-low-power applications.

Does the MCF52212CAE50 include an integrated USB transceiver?

Yes, the MCF52212CAE50 includes an integrated USB transceiver supporting full-speed and low-speed operation. As documented in the MCF52211 datasheet Section 1.2.7 and Figure 1, the USB On-The-Go (OTG) controller incorporates an on-die transceiver, eliminating the need for an external PHY chip. Pins USBDP and USBDM provide the differential USB interface directly, with internal ESD protection and impedance-matched drivers meeting USB 2.0 electrical specifications.

How many analog input channels does the MCF52212CAE50 ADC support?

The MCF52212CAE50 features an 8-channel 12-bit analog-to-digital converter (ADC), as confirmed in Table 1 (Family Configurations) and Section 1.2.11 of the MCF52211 datasheet. All eight channels (AN[7:0]) are accessible on the 64-pin LQFP package. The ADC supports simultaneous sampling of two channels using dual sample-and-hold circuits - a key capability for motor control and sensor synchronization - and allows unused analog inputs to be repurposed as general-purpose digital I/O.

What debug interface options are available on the MCF52212CAE50?

The MCF52212CAE50 supports Background Debug Mode (BDM) via dedicated DSI, DSO, and DSCLK pins, plus the ALLPST signal for halted-state detection - as specified in Section 1.2.3 of the MCF52211 datasheet. Unlike the 100-pin variants, the 64-pin LQFP package (including MCF52212CAE50) does not implement the full JTAG trace interface. However, BDM enables real-time in-circuit debugging, breakpoint setting, and memory inspection without requiring expensive emulators or halting full-speed operation.

Is the MCF52212CAE50 pin-compatible with other members of the MCF5221x family?

The MCF52212CAE50 is pin-compatible with the MCF52210 and MCF52212 variants in the same 64-pin LQFP package, as confirmed by Table 1 (Family Configurations) in the MCF52211 datasheet. All three share identical pinouts, power requirements, and peripheral mappings. However, it is not pin-compatible with the 81-pin MAPBGA or 100-pin LQFP variants (e.g., MCF52211CAG50), which offer additional UARTs, full JTAG, and different power pin arrangements.
