NXP Semiconductors MCF52233CVM60

Overview

MCF52233CVM60 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded industrial and networking applications. It operates at up to 60 MHz, integrates 256 KB Flash and 32 KB SRAM, features a Fast Ethernet Controller with on-chip EPHY, FlexCAN 2.0B, three UARTs, and an 8-channel 12-bit ADC - deployed in motor control, industrial gateways, and protocol-converged edge nodes.

For engineers reviewing the MCF52233CVM60 datasheet, MCF52233CVM60 pinout, MCF52233CVM60 application, or MCF52233CVM60 equivalent, key selection criteria include Ethernet + CAN coexistence, deterministic real-time interrupt handling via dual INTCs, EMAC-accelerated signal processing, and LQFP-80 package compatibility with BDM debug support.

Technical Context

The MCF52233CVM60 implements the ColdFire V2 core (ISA_A+), featuring a two-pipeline architecture (IFP/OEP), static operation, and EMAC unit supporting 16×16→32 and 32×32→32 multiply-accumulate operations. Its clock system includes a crystal/oscillator input with integrated PLL generating core, bus, and EPHY clocks.

It integrates dual interrupt controllers (INTC0/INTC1) with 7 fixed-level external interrupts and per-peripheral programmable vectors, plus a full-featured FEC with descriptor-ring DMA, on-die EPHY supporting 10/100BASE-TX with auto-negotiation and MDIO preamble suppression.

FAQ

What is the maximum operating frequency of the MCF52233CVM60?

The MCF52233CVM60 operates at a maximum core frequency of 60 MHz, delivering 56 Dhrystone 2.1 MIPS when executing from on-chip Flash memory. This frequency is achieved using the integrated PLL driven by an external 4–50 MHz crystal or oscillator connected to EXTAL/XTAL pins. The MCF52233CVM60 maintains full functionality-including Ethernet, CAN, and ADC-at this speed.

Does the MCF52233CVM60 include an integrated Ethernet PHY?

Yes, the MCF52233CVM60 integrates a full 10/100BASE-TX Ethernet PHY (EPHY) alongside its Fast Ethernet Controller (FEC). This eliminates the need for an external PHY chip, reducing BOM cost and PCB footprint. The EPHY supports auto-negotiation, MDIO management, jumbo packets, and loopback modes - all accessible through dedicated EPHY_RXD/EPHY_TXD pins on the LQFP-80 package.

How many CAN interfaces does the MCF52233CVM60 support?

The MCF52233CVM60 includes one FlexCAN 2.0B module supporting up to 1 Mbit/sec bit rate and 16 configurable message buffers. It implements full CAN protocol version 2.0B (Parts A and B), including standard and extended frames, programmable masks, and time-stamped messaging. Note that CANRX and CANTX are CMOS-level signals requiring an external CAN transceiver (e.g., TJA1042) for bus coupling.

What debug interfaces are available on the MCF52233CVM60 LQFP-80 package?

The MCF52233CVM60 in LQFP-80 includes the Background Debug Mode (BDM) serial interface (DSI, DSO, DSCLK pins) and the ALLPST signal for real-time halt detection. While full JTAG boundary-scan is limited to 112- and 121-pin packages, the BDM interface supports in-circuit debugging, flash programming, and real-time trace at full speed - sufficient for most industrial development workflows.

Is the MCF52233CVM60 pin-compatible with other members of the MCF5223x family?

Yes, the MCF52233CVM60 in LQFP-80 is pin-compatible with MCF52230CVM60, MCF52231CVM60, MCF52232CVM60, MCF52234CVM60, and MCF52235CVM60 - sharing identical pin assignments, power sequencing, and reset behavior. Differences lie in Flash size (128 KB vs. 256 KB), clock speed (50 MHz vs. 60 MHz), and optional peripherals (e.g., CAU in MCF52235), not pinout or electrical interface.
