NXP Semiconductors MCF52234CAL60

Overview

MCF52234CAL60 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, delivers 56 Dhrystone 2.1 MIPS, integrates 256 KB Flash and 32 KB SRAM, and features on-chip Fast Ethernet Controller (FEC), FlexCAN 2.0B, and a 12-bit 8-channel ADC - deployed in motor control, industrial gateways, and protocol-converged edge nodes.

For engineers reviewing the MCF52234CAL60 datasheet, MCF52234CAL60 pinout, MCF52234CAL60 application, or MCF52234CAL60 equivalent, key selection criteria include its LQFP-80 package, 60 MHz V2 ColdFire core with EMAC and CAU coprocessor, integrated EPHY transceiver, and support for real-time deterministic CAN/Ethernet coexistence in resource-constrained systems.

Technical Context

The MCF52234CAL60 implements the ColdFire ISA_A+ instruction set with a dual-pipeline V2 core (IFP/OEP), static operation, and hardware divider. Its EMAC unit supports 16×16→32 and 32×32→32 multiply-accumulate operations with a 32-bit accumulator, enabling efficient DSP-like signal processing without external accelerators.

It integrates a full-featured FEC with on-chip EPHY supporting 10/100BASE-TX, auto-negotiation, and MDIO; a FlexCAN 2.0B module with 16 configurable message buffers and programmable bit rates up to 1 Mbps; and dual interrupt controllers (INTC0/INTC1) providing unique priority vectors for all peripherals plus seven fixed-level external interrupts.

FAQ

What is the maximum operating frequency of the MCF52234CAL60?

The MCF52234CAL60 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 with an external crystal or clock source applied to the EXTAL/XTAL pins. The MCF52234CAL60 datasheet specifies this as the absolute maximum rated performance under validated thermal and voltage conditions.

Does the MCF52234CAL60 include an integrated Ethernet PHY?

Yes, the MCF52234CAL60 includes a fully integrated Ethernet Physical Layer (EPHY) supporting 10/100BASE-TX operation. This eliminates the need for an external PHY IC and enables direct connection to Ethernet magnetics. The EPHY supports auto-negotiation, MDIO management, full/half-duplex modes, and jumbo packets - all documented in the MCF52234CAL60 electrical specifications section of the Freescale MCF52235 datasheet (Rev. 10).

How many CAN message buffers does the MCF52234CAL60 support?

The MCF52234CAL60 supports 16 configurable FlexCAN message buffers, each capable of holding up to 8 bytes of data and operating in either transmit or receive mode. These buffers support both standard (11-bit) and extended (29-bit) CAN identifiers, programmable bit rates up to 1 Mbps, and time-stamped message reception - as confirmed in Table 1 of the MCF52235 Family Configurations document covering MCF52234 variants.

What ADC resolution and conversion speed does the MCF52234CAL60 provide?

The MCF52234CAL60 features an 8-channel, 12-bit analog-to-digital converter with a minimum conversion time of 1.125 µs per sample. It supports simultaneous sampling across two channels - critical for motor control phase current measurement. Unused analog inputs can be reconfigured as digital GPIO, and conversion completion can trigger interrupts or DMA requests, as specified in Section 2.9 of the MCF52235 datasheet applicable to MCF52234CAL60.

Is the MCF52234CAL60 pin-compatible with other members of the MCF5223x family?

No, the MCF52234CAL60 is not universally pin-compatible across the MCF5223x family. While it shares the LQFP-80 package with MCF52230, MCF52231, and MCF52233, pin functions differ significantly due to variant-specific peripheral enablement - for example, FlexCAN signals are absent on MCF52230/MCF52231, and EPHY pins are only active on MCF52234/MCF52235. Always verify pin assignments against the specific device's datasheet table.
