NXP Semiconductors MCF52210CAE66

Overview

MCF52210CAE66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring deterministic real-time performance, integrated peripherals, and low-power operation. It features a 66 MHz ColdFire core delivering 62 MIPS (Dhrystone 2.1), 64 KB flash memory, 16 KB SRAM, USB OTG, three UARTs, two I²C interfaces, QSPI, 8-channel 12-bit ADC, four 32-bit DMA timers, and dual 16-bit periodic interrupt timers - deployed in industrial motor control, portable instrumentation, and USB-enabled edge devices.

For engineers reviewing the MCF52210CAE66 datasheet, MCF52210CAE66 pinout, MCF52210CAE66 application, or MCF52210CAE66 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives with documented differences, and supply-ready procurement guidance - all grounded in the official MCF52211 Rev. 2 datasheet and Freescale's family configuration table.

Technical Context

The MCF52210CAE66 implements the ColdFire V2 core (ISA_A+), featuring static 32-bit RISC architecture with MAC unit and hardware divider, operating at 66 MHz with 62 MIPS performance. Its clock system integrates an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider, and support for crystal or external clock sources - enabling flexible low-power mode selection including sleep and stop states.

Peripheral integration includes USB OTG dual-mode controller (full-speed/low-speed, 16 endpoints), three UARTs (two with RTS/CTS), two I²C masters/slaves, QSPI master-only interface, and parallel 8-channel 12-bit ADC with simultaneous sampling capability - all connected via high-speed local bus to dual-ported SRAM and interleaved flash for deterministic access latency.

FAQ

What is the maximum operating frequency of the MCF52210CAE66?

The MCF52210CAE66 operates at a maximum system clock frequency of 66 MHz, derived from its internal PLL locked to either an external crystal (4–25 MHz) or the on-chip 8 MHz relaxation oscillator. This yields 62 MIPS performance per Dhrystone 2.1 benchmark when executing from internal flash memory.

Does the MCF52210CAE66 support USB host functionality?

Yes, the MCF52210CAE66 integrates a full USB On-The-Go (OTG) controller that supports both host and device modes. It complies with USB 1.1 and 2.0 specifications for full-speed/low-speed operation and includes 16 bidirectional endpoints with DMA or FIFO data path options - eliminating the need for external USB host controllers.

How many analog input channels does the MCF52210CAE66 ADC support?

The MCF52210CAE66 features an 8-channel, 12-bit analog-to-digital converter (ADC) with simultaneous sampling capability across two independent S/H circuits. All eight channels (AN0–AN7) are accessible in the LQFP-64 package, and unused analog inputs may be reconfigured as general-purpose I/O pins with programmable drive strength.

Is the MCF52210CAE66 pin-compatible with other ColdFire family members?

The MCF52210CAE66 in LQFP-64 packaging shares identical pinout with MCF52211CAE66, MCF52212CAE66, and MCF52213CAE66 per Freescale's family configuration table. However, peripheral enablement differs - for example, MCF52210CAE66 lacks the third UART present in 100-pin variants and has reduced flash (64 KB vs. 128 KB in MCF52211).

What debug interfaces are supported by the MCF52210CAE66?

The MCF52210CAE66 supports Background Debug Mode (BDM) and IEEE 1149.1 JTAG boundary scan via dedicated pins (TMS, TDI, TDO, TCK, TRST). While full real-time trace is limited to 100-pin packages, the LQFP-64 variant retains functional BDM for in-circuit debugging, breakpoint setting, and flash programming using standard Freescale/ColdFire development tools.
