FAQ

What is the maximum operating frequency of the MCF52234CVM60?

The MCF52234CVM60 operates at a maximum frequency of 60 MHz. This clock speed enables 56 Dhrystone 2.1 MIPS performance when executing code from on-chip Flash memory. The device achieves this using an integrated PLL that multiplies the input crystal or oscillator frequency, and its V2 ColdFire core is fully rated for stable operation at this speed under industrial temperature conditions (–40°C to +105°C).

Does the MCF52234CVM60 include an integrated Ethernet PHY?

Yes, the MCF52234CVM60 includes an on-chip Ethernet transceiver (EPHY) compliant with 10/100BASE-TX standards. It supports auto-negotiation, MDIO management, and full/half-duplex operation. The EPHY connects directly to external magnetics via EPHY_RXD[3:0] and EPHY_TXD[3:0] pins - eliminating the need for an external PHY IC in most industrial Ethernet designs.

How many UART interfaces does the MCF52234CVM60 support?

The MCF52234CVM60 supports three universal asynchronous/synchronous receiver/transmitters (UARTs). All three UARTs operate independently, support DMA and FIFO buffering, and are configurable for 5–8 bit data formats with parity and 1–2 stop bits. UART2 shares pins with GPIO in the LQFP-80 package, requiring careful multiplexing configuration during initialization.

What ADC resolution and channel count does the MCF52234CVM60 provide?

The MCF52234CVM60 integrates an 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter. It achieves a minimum conversion time of 1.125 µs and supports simultaneous sampling on two channels - critical for vector-controlled motor drives. Unused analog input pins (AN[7:0]) can be reconfigured as general-purpose digital I/O.

Is the MCF52234CVM60 pin-compatible with other members of the MCF5223x family?

Yes, the MCF52234CVM60 in LQFP-80 is pin-compatible with MCF52230CVM60, MCF52231CVM60, MCF52232CVM60, and MCF52233CVM60 - sharing identical pin assignments, power sequencing, and peripheral signal routing. Differences lie in Flash size (128 KB vs. 256 KB) and feature enablement (e.g., FlexCAN presence), not pin function or electrical behavior.
