Product details
Overview
MCF52211CEP66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP package, operating up to 66 MHz with 128 KB flash and 16 KB SRAM. It integrates USB OTG, three UARTs, dual I²C, QSPI, 8-channel 12-bit ADC, four 32-bit DMA timers, and real-time clock - deployed in industrial control panels requiring deterministic timing and field-upgradable firmware.
For engineers reviewing the MCF52211CEP66 datasheet, MCF52211CEP66 pinout, MCF52211CEP66 application, or MCF52211CEP66 equivalent, key selection criteria include USB OTG host/device dual-mode support, 66 MHz V2 ColdFire core performance (76 MIPS Dhrystone), 128 KB on-chip flash for secure firmware storage, and 8-channel simultaneous-sampling ADC for motor current sensing.
Technical Context
The MCF52211CEP66 implements the ColdFire ISA_A+ instruction set with hardware MAC unit and 32-bit accumulator, enabling efficient DSP-like operations at 66 MHz. Its clock system combines an 8 MHz on-chip relaxation oscillator, external crystal input, and integrated PLL with programmable pre-divider and low-power dividers.
Peripheral integration includes a full-featured USB OTG controller compliant with USB 1.1/2.0, supporting 16 bidirectional endpoints and DMA/FIFO data interfaces. The ADC supports simultaneous sampling across two channels with configurable interrupt triggers on zero-crossing or threshold violation - critical for closed-loop motor control.

FAQ
What is the maximum operating frequency of the MCF52211CEP66?
The MCF52211CEP66 operates at a maximum system clock frequency of 66 MHz, derived from its integrated PLL locked to either an external crystal or the internal 8 MHz relaxation oscillator. This yields 76 MIPS performance per Dhrystone 2.1 benchmark when executing from internal flash memory - sufficient for real-time control loops with sub-10 µs cycle times.
Does the MCF52211CEP66 support USB device and host functionality simultaneously?
Yes, the MCF52211CEP66 integrates a USB On-The-Go (OTG) controller compliant with USB 1.1 and 2.0 specifications, supporting both full-speed and low-speed modes. It can dynamically switch between host and device roles using the OTG protocol logic - enabling direct device-to-device communication without requiring a PC host, as confirmed in Section 1.2.7 of the official datasheet.
How many analog input channels does the MCF52211CEP66 ADC support, and what is its resolution?
The MCF52211CEP66 features an 8-channel, 12-bit successive approximation register (SAR) ADC with minimum conversion time of 1.125 µs. It supports simultaneous sampling across two channels using independent sample-and-hold circuits - a capability explicitly documented in Section 1.2.11 for motor control applications requiring phase current synchronization.
What debug interfaces are available on the MCF52211CEP66?
The MCF52211CEP66 provides both JTAG (IEEE 1149.1) and Background Debug Mode (BDM) interfaces. While the full debug/trace capability (including PST/DDATA ports) is limited to 100-pin packages, the 64-pin MCF52211CEP66 retains dedicated debug serial I/O (DSI/DSO/DSCLK) and the ALLPST signal - enabling real-time halt detection and basic in-circuit debugging per Section 1.2.3 of the datasheet.
Is the MCF52211CEP66 pin-compatible with other members of the MCF5221x family?
No - the MCF52211CEP66 in 64-pin LQFP is not pin-compatible with MCF52210, MCF52212, or MCF52213 variants, nor with the 81-ball MAPBGA or 100-pin LQFP versions. Pin assignments differ significantly across packages, and UART count varies by package (e.g., third UART omitted in 64-pin LQFP). Refer to Table 1 and mechanical drawings in Sections 3.1–3.4 for exact mapping.
