NXP Semiconductors MCF52233CAF60

Overview

MCF52233CAF60 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded industrial and networking applications. It features a 60 MHz CPU core delivering 56 Dhrystone 2.1 MIPS, 256 KB on-chip Flash, 32 KB SRAM, integrated 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 devices.

For engineers reviewing the MCF52233CAF60 datasheet, MCF52233CAF60 pinout, MCF52233CAF60 application, or MCF52233CAF60 equivalent, key selection considerations include its LQFP-80 package, 60 MHz operation with EMAC acceleration, integrated Ethernet PHY, CAN 2.0B support, and verified compatibility with MCF52235-family toolchains and reference designs.

Technical Context

The MCF52233CAF60 implements the ColdFire V2 core with dual-pipeline architecture (IFP/OEP), ISA_A+ instruction set, and enhanced multiply-accumulate (EMAC) unit supporting 16×16→32 and 32×32→32 operations. Its clock system integrates a PLL with crystal/oscillator input and generates core, peripheral, and EPHY clocks from a single source.

It integrates two interrupt controllers (INTC0/INTC1) with 7 fixed-level external interrupts and per-peripheral programmable vectors, plus full BDM debug support and JTAG boundary-scan - though full real-time trace is limited to 112-/121-pin packages; the 80-pin variant retains dedicated DSI/DSO/DSCLK and ALLPST signals.

Compared with MCF52235CAG60, MCF52233CAF60 omits CAU/RNG but matches all core peripherals and timing - making it ideal for cost-sensitive Ethernet/CAN nodes where crypto is handled externally or in software. Versus K64F120M, it trades raw ARM performance for tighter integration of PHY and CAN, reducing bill-of-materials and layout complexity.

FAQ

What is the maximum operating frequency of the MCF52233CAF60?

The MCF52233CAF60 operates at a maximum core frequency of 60 MHz, enabled by its ColdFire V2 processor core and integrated PLL. This delivers 56 Dhrystone 2.1 MIPS performance when executing from on-chip Flash memory, with EMAC acceleration enhancing signal processing throughput. The 60 MHz rating is validated across industrial temperature ranges and power supply conditions specified in the official electrical characteristics table.

Does the MCF52233CAF60 include an integrated Ethernet PHY?

Yes, the MCF52233CAF60 includes a fully integrated Ethernet Physical Layer (EPHY) supporting 10/100BASE-TX operation. This eliminates the need for an external PHY IC and simplifies board design - the EPHY provides differential TX/RX pairs, auto-negotiation, MDIO management, and loopback modes. Its operation is tightly coupled with the on-chip Fast Ethernet Controller (FEC) to form a complete MAC+PHY solution.

How many CAN message buffers does the MCF52233CAF60 support?

The MCF52233CAF60 implements the FlexCAN 2.0B module with 16 configurable message buffers. Each buffer supports standard or extended CAN frames (up to 8 bytes payload), programmable bit rates up to 1 Mbit/s, and hardware time stamping. Unused buffers may be repurposed as general-purpose RAM, and the module includes three programmable mask registers for flexible filtering.

What ADC resolution and conversion speed does the MCF52233CAF60 provide?

The MCF52233CAF60 features an 8-channel, 12-bit successive-approximation ADC with a minimum conversion time of 1.125 µs. It supports simultaneous sampling on two channels - critical for motor control current reconstruction - and offers configurable triggers, interrupt options (conversion complete, zero crossing, limit violation), and digital I/O reuse of unused analog inputs.

Is the MCF52233CAF60 pin-compatible with other members of the MCF5223x family?

Yes, the MCF52233CAF60 in LQFP-80 packaging shares identical pinout and package dimensions with MCF52230CAF60, MCF52231CAF60, MCF52232CAF60, and MCF52234CAF60. All share the same 80-pin assignment, power/ground layout, and peripheral signal mapping - enabling hardware reuse across variants differentiated only by Flash size, clock speed, or feature enablement (e.g., CAU).
