NXP Semiconductors MCF52213AE50

Overview

MCF52213AE50 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring deterministic real-time response, integrated analog acquisition, and USB connectivity. It features a 50 MHz ColdFire core delivering 46 MIPS (Dhrystone 2.1), 128 KB flash, 8 KB SRAM, an 8-channel 12-bit ADC with 1.125 µs conversion time, USB OTG controller, three UARTs, two I²C modules, QSPI, four 32-bit DMA timers, and dual watchdog timers.

For engineers reviewing the MCF52213AE50 datasheet, MCF52213AE50 pinout, MCF52213AE50 application, or MCF52213AE50 equivalent, key selection considerations include its 50 MHz clock rating, 128/8 KB Flash/SRAM configuration, LQFP-64 package mapping, USB OTG dual-mode support, and compatibility within the MCF5221x family for firmware reuse across performance tiers.

Technical Context

The MCF52213AE50 implements the ColdFire Version 2 ISA_A+ core with MAC unit and hardware divider, operating at a fixed 50 MHz system clock - distinct from the 66/80 MHz variants in the same family. Its clock generation includes an on-chip 8 MHz relaxation oscillator, PLL, and low-power dividers enabling flexible power/performance trade-offs.

Peripheral integration centers on deterministic I/O control: the 8-channel 12-bit ADC supports simultaneous sampling for motor current sensing; four 32-bit DMA-capable timers provide precise input capture/output compare with 20 ns resolution at 50 MHz; and the USB OTG controller supports full-speed host/device operation with 16 endpoints and DMA/FIFO data interfaces.

FAQ

What is the maximum operating frequency of the MCF52213AE50?

The MCF52213AE50 operates at a fixed maximum system clock frequency of 50 MHz, as defined by its factory-configured PLL settings and documented in the MCF52211 Rev. 2 datasheet Table 1. This differs from other family members like the MCF52211 (66/80 MHz) and ensures consistent timing margins for real-time control loops without overclocking risk. The MCF52213AE50 delivers 46 MIPS (Dhrystone 2.1) at this frequency.

Does the MCF52213AE50 support USB device and host modes simultaneously?

Yes, the MCF52213AE50 integrates a USB On-The-Go (OTG) controller compliant with USB 1.1 and 2.0 specifications, enabling dynamic role switching between full-speed device and host modes. Its 16 bidirectional endpoints and integrated transceiver allow the MCF52213AE50 to enumerate as a CDC ACM device or act as a host for HID peripherals - all without external PHY components.

How much on-chip memory does the MCF52213AE50 include?

The MCF52213AE50 contains 128 KB of on-chip flash memory for program storage and 8 KB of static RAM for data and stack operations. This configuration is confirmed in Table 1 of the MCF52211 Rev. 2 datasheet under the "52213" row. The flash supports in-system programming via EzPort or USB, and the SRAM is dual-ported to allow concurrent CPU and DMA access - essential for real-time buffering.

What ADC capabilities does the MCF52213AE50 provide?

The MCF52213AE50 features an 8-channel, 12-bit analog-to-digital converter with a minimum conversion time of 1.125 µs. It supports simultaneous sampling on two channels - critical for motor phase current measurement - and offers programmable interrupts for out-of-range detection and zero-crossing events. Unused ADC inputs can be reconfigured as general-purpose I/O pins, increasing pin utilization flexibility in the MCF52213AE50 design.

Is the MCF52213AE50 pin-compatible with other MCF5221x family members?

The MCF52213AE50 in LQFP-64 package shares identical pinout and electrical characteristics with the MCF52210, MCF52211, and MCF52212 in the same 64-pin LQFP variant, as confirmed in Table 1 and mechanical drawings of the MCF52211 Rev. 2 datasheet. This allows direct PCB reuse across performance and memory variants - provided clock configuration and firmware account for differences in SRAM size and peripheral enablement.
