For engineers reviewing the MCF52211CAE66 datasheet, MCF52211CAE66 pinout, MCF52211CAE66 application, or MCF52211CAE66 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-ready availability details - all grounded in the official Rev. 2 datasheet and Freescale/NXP product documentation.

Technical Context

The MCF52211CAE66 implements the ColdFire V2 core with MAC unit and hardware divider, delivering 76 MIPS at 80 MHz (derated to 66 MHz for this variant), supporting Dhrystone 2.1 benchmarking and signal-processing workloads. Its on-chip clock system integrates an 8 MHz relaxation oscillator, PLL, and programmable dividers enabling flexible low-power and high-precision timing modes.

Peripheral integration includes USB OTG with 16 bidirectional endpoints, dual I²C masters/slaves, QSPI master-only interface with 16-entry queue, and simultaneous-sampling dual 12-bit ADC converters optimized for motor control feedback. The interrupt controller handles 57 sources with individually programmable priority and vectoring.

FAQ

What is the maximum operating frequency of the MCF52211CAE66?

The MCF52211CAE66 operates at a maximum system clock frequency of 66 MHz, derived from its ColdFire V2 core with integrated PLL. This frequency is specified in the official Freescale datasheet Rev. 2 and validated across temperature and voltage ranges. The core delivers 76 MIPS at 80 MHz, but the CAE66 suffix denotes the 66 MHz speed grade. MCF52211CAE66 maintains full peripheral functionality at this rated speed, including USB OTG, ADC, and timer modules.

Does the MCF52211CAE66 include an integrated USB transceiver?

Yes, the MCF52211CAE66 integrates a full-speed/low-speed USB transceiver compliant with USB 1.1 and 2.0 specifications. It supports USB On-The-Go (OTG) dual-mode operation with 16 bidirectional endpoints and DMA/FIFO data path options. No external PHY is required - USB_DP and USB_DM pins connect directly to the USB connector. This capability is confirmed in Section 1.2.7 and Table 1 of the MCF52211 Rev. 2 datasheet. MCF52211CAE66 uses this transceiver for both device and host roles in embedded applications.

How much on-chip memory does the MCF52211CAE66 provide?

The MCF52211CAE66 includes 128 KB of on-chip flash memory and 16 KB of dual-ported static RAM. Flash is organized in four 16 KB banks for interleaved access, enabling 2-1-1-1 read timing. SRAM supports concurrent CPU and DMA access, critical for real-time buffering. These values are explicitly stated in Table 1 (Family Configurations) and Section 1.2.5 of the Rev. 2 datasheet. MCF52211CAE66 leverages this memory layout for zero-wait-state execution and deterministic interrupt response.

Is the MCF52211CAE66 pin-compatible with other members of the MCF5221x family?

Yes, the MCF52211CAE66 in LQFP–64 package is pin-compatible with MCF52210CAE66, MCF52212CAE66, and MCF52213CAE66 in the same 64-pin LQFP variant. Pin mappings for power, clocks, UARTs, I²C, ADC, and timers are identical across these variants. Differences lie in peripheral enablement (e.g., USB OTG disabled in MCF52210) and memory sizing - not pin function. This compatibility is documented in Section 1 (Family Configurations) and mechanical drawings of the Rev. 2 datasheet. MCF52211CAE66 allows drop-in replacement where USB and full flash/SRAM are required.

What debug interfaces are supported by the MCF52211CAE66?

The MCF52211CAE66 supports Background Debug Mode (BDM) via a dedicated single-wire debug interface and IEEE 1149.1 JTAG for boundary scan and emulation. BDM enables real-time in-circuit debugging without halting peripherals; JTAG supports production board testing and programming. While full trace capability is limited to 100-pin packages, the 64-pin MCF52211CAE66 retains DSI/DSO/DSCLK signals and ALLPST status output per Section 1.2.3 of the datasheet. MCF52211CAE66 uses these interfaces for firmware validation and manufacturing test across industrial deployments.
