MCF52235CAL60 Visão geral
A microcontroller (MCU) is a complete computer system on a single integrated circuit, combining a processor core, memory, and programmable peripherals. Within the power-management and embedded control hierarchy, 32-bit MCUs such as the MCF5223x family sit above 8-bit controllers and are typically used where network connectivity, moderate computing throughput, and deterministic real-time response are required in a single chip.
Key features include the ColdFire V2 reduced instruction set computing (RISC) core at 60 MHz, 256 KB (256K x 8) of on-chip flash for code and data storage, a 10/100 Mbps Fast Ethernet MAC plus integrated PHY for physical-layer connectivity, and a hardware cryptographic acceleration unit that offloads encryption tasks from the CPU. The combination of Ethernet and crypto acceleration in a single-chip 32-bit controller distinguishes the MCF52235 from the base MCF5223x peripheral set.
Technically, the device belongs to the Freescale (now NXP) ColdFire family of RISC microcontrollers. The MCF5223x family members are pin-to-pin compatible within like packages: MCF52231 adds a CAN module, MCF52233 adds 128 KB of flash, MCF52234 adds a CAN module and 128 KB of flash, and MCF52235 adds the cryptographic acceleration unit, a CAN module, and 128 KB of flash to the standard peripheral set. This allows PCB-level migration between family members.
Typical applications include industrial embedded Ethernet nodes, networked control and building-automation endpoints, secure communication gateways that benefit from the hardware crypto engine, and legacy system maintenance for designs already qualified on the ColdFire V2 architecture.
Design consideration: NXP lists this part as NRND (Not Recommended for New Designs), so new projects should evaluate supported NXP or third-party alternatives; existing designs can leverage family pin compatibility for last-time-buy mitigation.

Aplicações típicas
MCF52235CAL60 é adequado para 6 aplicaçãos: Industrial Embedded Ethernet Nodes, Secure Communication Gateways, Building Automation Controllers, Networked Sensor and Data Acquisition Systems, Legacy ColdFire System Maintenance, Automotive and CAN-Bus Bridging Applications.
Industrial Embedded Ethernet Nodes
The MCF52235CAL60 fits industrial Ethernet node designs because it integrates a 10/100 Mbps Fast Ethernet controller (FEC) with a built-in physical layer (EPHY), eliminating an external PHY chip and its magnetics-matching complexity. Running at 60 MHz, the ColdFire V2 core handles TCP/IP stacks such as NXP-supplied RTOS networking with headroom for protocol processing. In a typical design, the EPHY connects through magnetics to an RJ45 jack while the CAN module links to field buses, letting one chip bridge factory-floor protocols to plant networks. The single-chip integration reduces BOM cost and board area in 112-LQFP (20x20 mm), and the 256 KB flash accommodates firmware plus configuration storage for control nodes that must operate continuously in electrically noisy industrial environments.
Recomendado
Secure Communication Gateways
The distinguishing feature of the MCF52235CAL60 within its family is the hardware cryptographic acceleration unit, which offloads encryption from the 60 MHz CPU and enables secure protocol endpoints without the throughput penalty of software-only cryptography. Combined with the on-chip 10/100 Ethernet MAC and PHY, the device can terminate or relay encrypted sessions at the network edge. In gateway architectures, incoming Ethernet traffic is processed by the FEC while the crypto engine handles cipher operations in parallel, and the CAN module exchanges data with lower-speed vehicle or industrial subnets. The 256 KB flash stores both application code and key material handling routines, and the 112-LQFP package provides enough GPIO for status, diagnostics, and auxiliary interfaces.
Recomendado
Building Automation Controllers
Building automation endpoints benefit from the MCF52235CAL60's combination of Ethernet connectivity and a CAN module on one chip. The integrated EPHY allows direct attachment to structured-cabling networks for BMS supervisory communication, while CAN handles room-level device buses. The 60 MHz ColdFire V2 core runs deterministic control loops and a lightweight TCP/IP stack concurrently; the 32-bit RISC architecture provides predictable interrupt latency needed for scheduling and HVAC control tasks. Because family members are pin-to-pin compatible, a single controller PCB can be populated with MCF52230 through MCF52235 to create product tiers - from basic I/O controllers (MCF52230) to secure networked controllers with encryption (MCF52235) - without changing the board layout in the 112-LQFP 20x20 mm footprint.
Recomendado
Networked Sensor and Data Acquisition Systems
For distributed measurement systems, the MCF52235CAL60 offers the on-chip 10/100 Ethernet FEC plus EPHY to stream acquired data directly onto a LAN without external network controllers. The 60 MHz ColdFire V2 core processes sampling, buffering, and packet assembly while the 256 KB flash retains calibration tables and firmware. Typical topologies place the MCU between front-end signal conditioning and the RJ45 physical interface through the integrated EPHY, so one chip manages both analog-to-protocol conversion and communication. Third-party product data notes the device includes a 12-bit ADC class peripheral set in the MCF5223x family, supporting direct sensor digitization. The single-chip architecture reduces component count and improves reliability in remote installations where board-level service is impractical.
Recomendado
Legacy ColdFire System Maintenance
A significant ongoing use of the MCF52235CAL60 is sustaining installed-base equipment designed around the Freescale ColdFire V2 architecture. Because the part is NRND, maintenance programs source remaining authorized stock via DigiKey, Mouser, or Rochester Electronics, which lists the original Freescale part as a licensed continued-source supplier. The device's pin compatibility across the MCF5223x family (per NXP: all members are pin-to-pin compatible within like packages) lets repair and small-batch production substitute family members when the crypto or CAN features are unused. Firmware written for the ColdFire V2 instruction set and the MCF5223x peripheral register map runs unmodified, avoiding costly recertification of qualified industrial, medical, and transportation equipment still in long service life cycles.
Recomendado
Automotive and CAN-Bus Bridging Applications
The MCF52235CAL60 includes a CAN module alongside its Ethernet interface, making it suitable for gateway products that translate between vehicle or industrial CAN buses and IP-based networks - for example, fleet telematics, EV-charging station controllers, and diagnostic bridges. The 60 MHz ColdFire V2 core services CAN message handling and Ethernet protocol stacks concurrently, while the crypto acceleration unit secures data before it leaves the local network. NXP family data confirms MCF52231, MCF52234, and MCF52235 all provide CAN, so designers can select the memory and security tier needed while retaining the same 112-LQFP footprint. The integrated EPHY removes the external PHY, an advantage in compact telematics units where board space and BOM cost are constrained.

Notas de projeto
The 112-LQFP (20x20 mm) MCF52235CAL60 requires a solid ground plane and decoupling capacitors (typically 0.1 uF) at every VDD pin pair placed within 2-3 mm of the pin, per standard NXP MCF5223x hardware design guidance. Because the Ethernet PHY is on-chip, route the EPHY differential pairs (TX/RX) to the magnetics with controlled impedance and keep them away from clock lines; consult the NXP MCF5223x reference manual hardware design chapter for PHY magnetics and RJ45 termination details.
The part is NRND. Do not start new designs without a lifecycle plan: verify remaining authorized stock, request Rochester Electronics continued-source quotes, and document a migration path. Also note that family members are only pin-to-pin compatible within LIKE packages - the CAL suffix (112-LQFP) must match; substituting a different package suffix (e.g., CVM) requires a different land pattern.
Estimated: the integrated 10/100 EPHY dominates supply current in networked designs; budget power for the PHY being continuously active, not just the 60 MHz core. Confirm exact supply voltage and current figures against the official MCF5223x datasheet power chapter, as regulator sizing and thermal margins depend on total core+PHY+I/O current under maximum Ethernet utilization.
