NXP Semiconductors MCF52210CVM66

Overview

MCF52210CVM66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP package, operating at 66 MHz with 64 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 MCF52210CVM66 datasheet, MCF52210CVM66 pinout, MCF52210CVM66 application, or MCF52210CVM66 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral interoperability, and precise alternative selection guidance for legacy ColdFire-based designs.

Technical Context

The MCF52210CVM66 implements the ColdFire V2 core with ISA_A+ instruction set, including hardware MAC unit and 32-bit accumulator supporting 16×16→32 and 32×32→32 operations. Its clock system combines an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider, and external crystal support - enabling stable 66 MHz core operation with low-jitter USB clock derivation.

Peripheral integration follows tightly coupled memory-mapped architecture: USB OTG controller supports full-speed host/device modes with 16 endpoints and DMA/FIFO interfaces; the 8-channel 12-bit ADC achieves 1.125 µs conversion time with simultaneous sampling capability for motor phase current sensing.

FAQ

What is the maximum operating frequency of the MCF52210CVM66?

The MCF52210CVM66 operates at a maximum core frequency of 66 MHz, delivering approximately 57 MIPS (Dhrystone 2.1). This frequency is achieved using the integrated PLL locked to an external crystal or the on-chip 8 MHz relaxation oscillator. The device is rated for reliable operation across industrial temperature ranges (–40°C to +85°C) at this speed, with timing margins verified per Freescale's MCF52211 datasheet Rev. 2.

Does the MCF52210CVM66 support USB host functionality?

Yes, the MCF52210CVM66 includes a full-speed USB On-The-Go (OTG) controller that supports both host and device modes. In host mode, it can enumerate and communicate with standard USB peripherals such as HID devices, mass storage, or CDC-class devices - all without requiring an external PHY. The USB_DP/USB_DM pins are routed internally to the OTG transceiver, and endpoint configuration is managed via dedicated USB registers in the memory map.

How many analog input channels does the MCF52210CVM66 ADC support?

The MCF52210CVM66 features an 8-channel, 12-bit analog-to-digital converter (ADC) with single-ended or differential input capability. All eight channels (AN0–AN7) are accessible in the 64-pin LQFP package. Unused analog inputs may be reconfigured as general-purpose digital I/O pins. Conversion time is as fast as 1.125 µs, and simultaneous sampling across two channels is supported for precise phase-current measurement in motor control applications.

Is the MCF52210CVM66 pin-compatible with other members of the MCF5221x family?

Yes, the MCF52210CVM66 is pin-compatible with the MCF52211CVM66, MCF52212CVM66, and MCF52213CVM66 in the 64-pin LQFP package. All share identical pin assignments for power, clocks, USB, UARTs, I²C, QSPI, ADC, timers, and GPIO. Differences lie in internal configuration - flash size (64 KB vs. 128 KB), SRAM (16 KB vs. 8 KB), and maximum clock frequency (66 MHz vs. 80 MHz) - allowing drop-in replacement where firmware fits and timing requirements permit.

What debug interfaces are available on the MCF52210CVM66?

The MCF52210CVM66 supports Background Debug Mode (BDM) via dedicated TMS, TDI, TDO, TRST, and TCLK pins, compatible with standard ColdFire debug tools. It also implements IEEE 1149.1 JTAG boundary-scan for board-level testing. While full real-time trace is limited to 100-pin packages, the 64-pin variant retains essential debug signals including ALLPST and dedicated DSI/DSO/DSCLK lines for breakpoint-controlled halting and register inspection during development.
