NXP Semiconductors MCF52213CAE50

Overview

MCF52213CAE50 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control in industrial and automotive systems. It features a 50 MHz CPU core delivering 46 MIPS (Dhrystone 2.1), 128 KB on-chip flash memory, 8 KB SRAM, USB OTG, three UARTs, two I²C interfaces, QSPI, 8-channel 12-bit ADC, and four 32-bit DMA-capable timers - deployed in motor control, sensor interface, and protocol gateway applications.

For engineers reviewing the MCF52213CAE50 datasheet, MCF52213CAE50 pinout, MCF52213CAE50 application, or MCF52213CAE50 equivalent, key selection criteria include its 50 MHz clock rating, 128 KB/8 KB Flash/SRAM configuration, LQFP-64 package compatibility, USB OTG dual-mode support, and verified peripheral integration across UART/I²C/QSPI/ADC subsystems.

Technical Context

The MCF52213CAE50 implements the ColdFire Version 2 ISA_A+ core with MAC unit and hardware divider, operating at 50 MHz with static design enabling full-speed operation down to 0 Hz. Its clock system integrates an 8 MHz on-chip relaxation oscillator, PLL, and programmable dividers supporting multiple low-power modes including sleep and stop.

Peripheral integration includes a full-featured USB OTG controller compliant with USB 1.1/2.0, three UARTs (with third UART multiplexed on LQFP-64), two independent I²C modules, and an 8-channel 12-bit ADC with simultaneous sampling capability for motor phase current sensing - all accessible via dedicated interrupt vectors and DMA channels.

FAQ

What is the maximum operating frequency of the MCF52213CAE50?

The MCF52213CAE50 operates at a maximum system clock frequency of 50 MHz, delivering 46 MIPS (Dhrystone 2.1). This frequency is fixed for the MCF52213 variant - unlike the MCF52211 which supports up to 80 MHz - and is achieved using the on-chip PLL locked to either an external crystal or the internal 8 MHz relaxation oscillator. The MCF52213CAE50's 50 MHz rating ensures consistent thermal and timing behavior across industrial temperature ranges.

Does the MCF52213CAE50 support USB device and host functionality simultaneously?

Yes, the MCF52213CAE50 integrates a USB On-The-Go (OTG) controller compliant with USB 1.1 and 2.0 specifications, enabling it to operate as either a full-speed/low-speed USB device or host - but not both concurrently in the same session. The OTG logic manages role negotiation via the ID pin, and the 16 bidirectional endpoints support complex configurations such as CDC ACM (virtual COM port) in device mode or MSC (mass storage) in host mode, all implemented within the MCF52213CAE50's on-die transceiver.

How much SRAM and flash memory does the MCF52213CAE50 include?

The MCF52213CAE50 contains 128 KB of on-chip flash memory and 8 KB of static RAM (SRAM). The flash is organized in interleaved banks supporting 2-1-1-1 read access timing, while the SRAM is dual-ported - allowing concurrent CPU and DMA access without contention. This memory configuration is confirmed in Table 1 (Family Configurations) of the MCF52211 datasheet Rev. 2, where MCF52213 is explicitly listed as 128/8 Kbytes (Flash/SRAM), distinguishing it from the 128/16 KB MCF52211 variant.

Which package type is used for the MCF52213CAE50?

The MCF52213CAE50 uses the 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as indicated by the "AE" suffix in the part number per Freescale's packaging nomenclature. This matches the mechanical outline in Section 3.1 of the MCF52211 datasheet Rev. 2. The LQFP-64 variant supports all core peripherals except the third UART, which is multiplexed with GPIO functions - a trade-off optimized for compact industrial control boards where board space is constrained.

Can the MCF52213CAE50 perform simultaneous sampling on multiple ADC channels?

Yes, the MCF52213CAE50's 8-channel 12-bit ADC supports true simultaneous sampling of two channels using its dual sample-and-hold (S/H) circuits - a feature explicitly documented in Section 1.2.11 of the MCF52211 datasheet Rev. 2. This capability is critical for vector-controlled motor drives, where phase current measurements must be time-aligned to avoid torque ripple. The ADC achieves ≤1.125 µs conversion time per channel, and unused analog inputs can be reconfigured as general-purpose I/O pins.
