Product details
Overview
MCF52233CAL60 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 Fast Ethernet Controller (FEC) with on-chip EPHY, FlexCAN 2.0B, three UARTs, and a 12-bit 8-channel ADC - deployed in motor control, industrial gateways, and protocol-converged edge nodes.
For engineers reviewing the MCF52233CAL60 datasheet, MCF52233CAL60 pinout, MCF52233CAL60 application, or MCF52233CAL60 equivalent, key selection considerations include its LQFP-80 package, 60 MHz V2 ColdFire core with EMAC and hardware divider, FEC+EPHY integration, absence of CAU (vs. MCF52235), and verified compatibility with ColdFire development toolchains including CodeWarrior and GDB-based debug via BDM/JTAG.
Technical Context
The MCF52233CAL60 implements the ColdFire V2 ISA_A+ core with static 32-bit architecture, dual-pipeline IFP/OEP execution, and enhanced multiply-accumulate (EMAC) unit supporting 16×16→32 and 32×32→32 operations. Its clock system includes crystal/oscillator input, programmable PLL, and dedicated clock generation for EPHY.
On-chip peripherals include a full-featured Fast Ethernet Controller with integrated 10/100BASE-TX transceiver (EPHY), FlexCAN 2.0B with 16 message buffers and 1 Mbps bit rate, three UARTs with FIFOs and DMA support, and an 8-channel 12-bit ADC with simultaneous sampling capability - all mapped to GPIO via configurable pin muxing (PADI).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52235CAG60 | Includes Cryptographic Acceleration Unit (CAU) and RNG; same 256 KB Flash/32 KB SRAM, 60 MHz V2 core, and LQFP-80 package. | Required for FIPS-140-2 compliant secure boot or hardware-accelerated TLS handshake - not needed for basic industrial control. | Select MCF52235CAG60 only if CAU-driven performance gain justifies higher cost and qualification effort. |
| Kinetis K60DN512ZVMD10 | ARM Cortex-M4 core @ 100 MHz, 512 KB Flash, 128 KB RAM, Ethernet MAC (no PHY), USB OTG, and hardware crypto (AES/SHA/RNG). | Better suited for USB host, floating-point math, or larger RTOS deployments - lacks integrated EPHY and has different peripheral mapping. | Choose K60DN512ZVMD10 when migrating to ARM ecosystem, requiring USB connectivity, or needing >32 KB RAM for complex protocol stacks. |
Compared with MCF52233CAL60, MCF52235CAG60 adds CAU for crypto acceleration but shares identical pinout and peripheral set; K60DN512ZVMD10 offers higher clock speed and ARM toolchain support but requires external PHY and redesign of driver layers - making MCF52233CAL60 optimal for cost-sensitive, EPHY-dependent ColdFire-based designs.

FAQ
What is the maximum operating frequency of the MCF52233CAL60?
The MCF52233CAL60 operates at a maximum frequency of 60 MHz. This clock speed is achieved using the on-chip PLL with external crystal input (typically 8–25 MHz). At 60 MHz, the V2 ColdFire core delivers 56 Dhrystone 2.1 MIPS, enabling real-time execution of Ethernet MAC processing, CAN message handling, and control algorithms without external acceleration. The MCF52233CAL60 maintains this frequency across its specified industrial temperature range (–40°C to +85°C) under proper power supply and thermal conditions.
Does the MCF52233CAL60 include an integrated Ethernet PHY?
Yes, the MCF52233CAL60 includes a fully integrated Ethernet Physical Layer transceiver (EPHY) supporting 10/100BASE-TX operation. This EPHY is tightly coupled to the Fast Ethernet Controller (FEC) and requires no external PHY chip or magnetics for basic operation. It supports auto-negotiation, full/half-duplex modes, MDIO preamble suppression, and jumbo packets - making the MCF52233CAL60 suitable for compact, cost-sensitive industrial Ethernet devices such as protocol gateways and remote I/O modules.
How much Flash and SRAM memory does the MCF52233CAL60 have?
The MCF52233CAL60 integrates 256 KB of on-chip Flash memory and 32 KB of static RAM (SRAM). The Flash is organized in four 32K×16-bit banks for interleaved access, enabling efficient code execution and field firmware updates. The SRAM is dual-ported, allowing concurrent CPU and DMA access - ideal for real-time buffering of Ethernet frames, CAN messages, or ADC sample streams. Both memories are directly mapped into the ColdFire's 4 GB address space and accessible without wait states at 60 MHz.
Is the MCF52233CAL60 pin-compatible with other members of the MCF5223x family?
Yes, the MCF52233CAL60 in LQFP-80 package is pin-compatible with MCF52230, MCF52231, MCF52232, MCF52234, and MCF52235 variants also offered in LQFP-80. All share identical pin assignments, power sequencing, and peripheral signal mapping. However, feature differentiation exists - for example, MCF52233CAL60 lacks the Cryptographic Acceleration Unit (CAU) present in MCF52235CAG60, and its Flash size (256 KB) exceeds MCF52230/31/32 (128 KB). Board designs can be reused across these variants with only firmware and configuration changes.
What debug interfaces does the MCF52233CAL60 support?
The MCF52233CAL60 supports Background Debug Mode (BDM) via dedicated DEBUG_B+ serial interface (DSI/DSO/DSCLK pins) and IEEE 1149.1 JTAG for boundary-scan testing. While the full real-time trace capability is limited to 112- and 121-pin packages, the LQFP-80 variant retains complete BDM functionality - including halt/resume, register read/write, memory access, and breakpoint setting - compatible with standard ColdFire debug tools like P&E Multilink and CodeWarrior IDE. The ALLPST signal is also present for detecting halted processor state.
