NXP Semiconductors MCF52211CAE80

Overview

MCF52211CAE80 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller operating at up to 80 MHz, featuring 128 KB flash, 16 KB SRAM, USB OTG, three UARTs, two I²C interfaces, QSPI, 12-bit 8-channel ADC, four 32-bit DMA timers, and real-time clock. It targets industrial control, motor drive, and embedded connectivity applications requiring integrated peripherals and deterministic timing.

For engineers reviewing the MCF52211CAE80 datasheet, MCF52211CAE80 pinout, MCF52211CAE80 application, or MCF52211CAE80 equivalent, key selection criteria include its 80 MHz ColdFire V2 core performance (76 MIPS Dhrystone), dual-port SRAM for concurrent CPU/DMA access, simultaneous-sampling ADC for motor control, USB OTG dual-mode support, and LQFP-64 package compatibility with BDM/JTAG debug.

Technical Context

The MCF52211CAE80 implements the ColdFire ISA_A+ instruction set with hardware MAC unit and 32-bit accumulator supporting 16×16→32 and 32×32→32 operations. Its V2 core uses decoupled two-pipeline architecture (IFP/OEP) with instruction buffer and real-time trace capability via PST/DDATA debug ports.

On-chip clock generation includes an 8 MHz on-chip relaxation oscillator, PLL with VDDPLL/VSSPLL isolation, and selectable system clock sources (crystal, OCO, or external). The interrupt controller supports 57 sources with programmable priority/level, and the DMA controller provides four channels with 8-/16-/32-bit and 16-byte burst transfer support.

FAQ

What is the maximum operating frequency of the MCF52211CAE80?

The MCF52211CAE80 operates at a maximum core frequency of 80 MHz, delivering 76 MIPS (Dhrystone 2.1) when running from internal flash memory. This frequency is achieved using the integrated PLL with external crystal or on-chip relaxation oscillator input, and is confirmed in the Freescale MCF52211 Rev. 2 datasheet Section 1.2.1.

Does the MCF52211CAE80 support USB host functionality?

Yes, the MCF52211CAE80 includes a USB On-The-Go (OTG) controller that supports both full-speed and low-speed USB host and device modes. It implements 16 bidirectional endpoints and supports DMA or FIFO data streaming, as documented in Section 1.2.7 of the MCF52211 Rev. 2 datasheet.

How many analog input channels does the MCF52211CAE80 ADC support?

The MCF52211CAE80 integrates an 8-channel 12-bit analog-to-digital converter (ADC) with dedicated AN0–AN7 pins. It supports simultaneous sampling of two channels-a key feature for motor current sensing-and offers ≤1.125 µs conversion time, per Section 1.2.11 of the official datasheet.

What debug interfaces are available on the MCF52211CAE80?

The MCF52211CAE80 provides Background Debug Mode (BDM) and IEEE 1149.1 JTAG interfaces. While full debug/trace capability (including PST/DDATA buses) is implemented, the LQFP-64 package includes the dedicated debug serial channel (DSI/DSO/DSCLK) and ALLPST signal-enabling real-time halt detection and basic in-circuit debugging per Section 1.2.3.

Is the MCF52211CAE80 pin-compatible with other members of the MCF5221x family?

The MCF52211CAE80 in LQFP-64 is pin-compatible with the MCF52210CAE66 and MCF52212CAE64 within the same package variant, sharing identical pin assignments for power, clocks, reset, peripherals, and GPIO. Differences in flash size or clock speed do not affect pinout, as verified in Table 1 and mechanical drawings of the MCF52211 Rev. 2 datasheet.
