NXP Semiconductors MCF52235CVM60

Overview

MCF52235CVM60 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control in industrial networking and real-time automation systems. 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, and a Cryptographic Acceleration Unit (CAU), and targets applications requiring deterministic timing, secure communications, and integrated connectivity.

For engineers reviewing the MCF52235CVM60 datasheet, MCF52235CVM60 pinout, MCF52235CVM60 application, or MCF52235CVM60 equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in the official Rev. 10 datasheet and Freescale/NXP product documentation.

Technical Context

The MCF52235CVM60 implements the ColdFire V2 core (ISA_A+), featuring a dual-pipeline architecture with instruction fetch (IFP) and operand execution (OEP) stages, EMAC unit supporting 16×16→32 and 32×32→32 operations, and hardware divider. Its clock system includes an integrated PLL with crystal/oscillator support and generates clocks for CPU, peripherals, and EPHY.

It integrates two interrupt controllers (INTC0/INTC1) with unique vectors per peripheral and seven fixed-level external interrupts, plus full JTAG IEEE 1149.1 boundary-scan and Background Debug Mode (BDM) - though full debug/trace is limited to 112- and 121-pin packages; the 80-pin LQFP variant supports BDM serial interface and ALLPST signal only.

FAQ

What is the maximum operating frequency of the MCF52235CVM60?

The MCF52235CVM60 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 external crystal (EXTAL/XTAL) or oscillator input, and is validated across commercial temperature range (–40°C to +85°C) per Section 2.5 of the Rev. 10 datasheet.

Does the MCF52235CVM60 include an integrated Ethernet PHY?

Yes, the MCF52235CVM60 integrates a fully functional 10/100BASE-TX Ethernet PHY (EPHY) compliant with IEEE 802.3u. It supports auto-negotiation, full/half-duplex, MDIO preamble suppression, and jumbo packets. The EPHY connects directly to magnetics via EPHY_RX[3:0] and EPHY_TX[3:0] pins - no external PHY IC is required for basic Ethernet operation.

What cryptographic functions does the CAU in the MCF52235CVM60 accelerate?

The Cryptographic Acceleration Unit (CAU) in the MCF52235CVM60 accelerates DES, 3DES, AES (128/192/256-bit), MD5, and SHA-1 algorithms. It also includes a FIPS-140 compliant random number generator. These functions are accessed via coprocessor instructions and offload compute-intensive operations from the ColdFire V2 core, enabling secure boot, encrypted communications, and digital signature verification in real time.

Is the MCF52235CVM60 pin-compatible with other ColdFire variants in the same package?

Yes, the MCF52235CVM60 in LQFP-80 is pin-compatible with other MCF522xx family members offered in the same 80-pin LQFP package (e.g., MCF52230CVM60, MCF52232CVM50), sharing identical pin assignments for power, clock, reset, GPIO, UART, I²C, QSPI, ADC, and EPHY interfaces. However, peripheral enablement (e.g., FlexCAN, CAU) varies by part number and must be verified in software configuration.

What debug interfaces are supported on the MCF52235CVM60?

The MCF52235CVM60 supports Background Debug Mode (BDM) via dedicated DSI/DSO/DSCLK pins and JTAG IEEE 1149.1 boundary-scan. Full real-time trace capability is not available on the 80-pin LQFP package; it is restricted to 112- and 121-pin variants. However, the 80-pin version retains BDM serial debugging, ALLPST halt-detection signal, and standard JTAG test access for board-level continuity testing.
