NXP Semiconductors MCF52230CAF60 is a 32-bit ColdFire V2 microcontroller operating at 60 MHz, with 128 KB of flash memory and an 80-LQFP package measuring 14 x 14 mm. It integrates a 10/100 Fast Ethernet controller, Ethernet physical layer, and 43 I/O, providing a compact embedded-control platform with network connectivity. A microcontroller is a programmable system-on-chip that combines a processor core, memory, peripherals, and I/O in one integrated component. The MCF52230 belongs to the ColdFire embedded-processor hierarchy and targets industrial networking, communications, automation, and control systems. Its Ethernet integration can reduce system complexity by combining protocol processing and physical-layer connectivity on the same device. Verified source information identifies the device as part of the MCF5223x family and specifies its 60 MHz ColdFire V2 core, 128 KB flash, 43 I/O, 10/100 Fast Ethernet controller, and Ethernet physical layer. The available NXP overview also describes the family as compact embedded controllers combining 32-bit control with Ethernet connectivity. Detailed RAM, voltage, temperature, timer, serial-interface, and package-pin information was not included in the supplied source data and is therefore not inferred here. The 80-LQFP package provides 80 external leads for power, ground, digital I/O, Ethernet, clock, and control functions. Its 14 x 14 mm outline supports compact embedded boards, but the relatively fine lead pitch requires careful PCB layout, clean ground distribution, and assembly-process control. Ethernet applications also need a suitably designed clock, magnetics, signal routing, power network, and physical-layer implementation. Typical uses include embedded Ethernet controllers, industrial automation equipment, communications equipment, network-connected sensors, and compact control systems. The MCU's 60 MHz processing rate provides computational headroom for protocol handling and real-time control, while integrated Ethernet avoids a separate host interface in many designs. Actual firmware performance and interface availability should still be verified against the complete manufacturer datasheet and errata. For a new design, confirm the exact peripheral set, electrical limits, memory map, pin multiplexing, and package tolerances in the NXP documentation before committing the PCB. For an existing design, validate clock configuration, Ethernet PHY implementation, startup behavior, and software initialization before substituting any device. This page distinguishes verified headline facts from unavailable detailed parameters rather than filling gaps with assumptions.

The NXP MCF52230CAL60 is a ColdFire V2 32-bit microcontroller featuring a 60 MHz core, 128 KB of on-chip Flash, and an integrated 10/100 Ethernet MAC+PHY (FEC+EPHY), housed in a 112-pin LQFP package operating from 3.0 V to 3.6 V. The part is marked NRND (Not Recommended for New Designs), making it suitable only for maintenance of existing designs and not for new product starts. Background: A ColdFire microcontroller is a 32-bit reduced instruction set computing (RISC) processor architecture originally derived from the Motorola 68000 family and now maintained by NXP Semiconductors. ColdFire V2 microcontrollers belong to the family of embedded microcontrollers (MCUs), which sit within the broader hierarchy of microprocessors -> microcontrollers -> embedded controllers. They are widely used in industrial control, factory automation, and networked embedded devices where deterministic 32-bit performance, low power, and integrated peripherals reduce total system BOM cost. Key differentiating specifications include the integrated Fast Ethernet Controller with embedded physical layer (FEC+EPHY), a 32-bit ColdFire V2 core running at 60 MHz delivering up to 56 MIPS, 128 KB of program Flash, 16 KB of SRAM, and a 4-channel DMA controller. The device also integrates a Cryptographic Acceleration Unit on related family members, multiple timers (including a 4-channel 32-bit timer and 4-channel 16-bit timer), an 8-channel 12-bit ADC, and a wide peripheral set including QSPI, I2C, UARTs, and a CAN module on related family members. Architecturally, the MCF52230CAL60 uses a variable-length ColdFire instruction set optimized for code density, a unified instruction/data cache-less memory architecture suitable for deterministic interrupt response, and integrated Ethernet DMA paths that offload packet handling. The integrated PHY eliminates external magnetics interface circuitry in many designs and reduces PCB complexity for connected industrial nodes. Typical applications include industrial Ethernet I/O modules, factory automation controllers, building automation gateways, networked sensor hubs, and serial-to-Ethernet protocol converters. The wide operating temperature range (-40C to +85C) and integrated Ethernet make it well-suited to industrial networking designs where an external MCU plus discrete Ethernet controller would inflate cost. When designing with the MCF52230CAL60, note that the part is NRND and NXP recommends migration to the Kinetis or i.MX RT families for new designs. Existing designs should validate the supply chain carefully, as authorized distributor stock is declining and lead times may extend significantly. Ensure the 3.3 V supply is well-decoupled and the integrated PHY is provided with a proper 50 ohm reference clock source per the MCF52235 reference manual. This page synthesizes NXP distributor pricing, drop-in ColdFire V2 family alternatives within the MCF5223x series, and practical maintenance-design notes not consolidated in a single place on the manufacturer's product page.

The part is listed by NXP as NRND (Not Recommended for New Designs) per the official NXP product page. What is a ColdFire V2 microcontroller? ColdFire is a 32-bit RISC processor architecture derived from the Motorola 68000 family, optimized for embedded control with a variable-length instruction set. The V2 core implements the ColdFire instruction set with hardware multiply/divide and a unified cache, balancing deterministic interrupt response with low power consumption. It belongs to the broader hierarchy: microcontroller -> embedded MCU -> 32-bit RISC MCU -> semiconductor IC. Key features include a 10/100 Mbps Ethernet MAC+PHY (FEC+EPHY), a CAN 2.0A/B controller, three UARTs, two I2C ports, two SPI/QSPI interfaces, an 8-channel 12-bit ADC, a 4-channel 32-bit timer, JTAG/BDM debug, and a Phase-Locked Loop (PLL) for clock synthesis. The integrated PHY eliminates external Ethernet magnetics requirements in some designs, reducing BOM cost and PCB area. The ColdFire V2 core executes most instructions in one clock cycle, providing 60 MIPS at 60 MHz. The Harvard-style memory architecture separates program Flash from data SRAM, and the 16-channel DMA engine offloads peripheral data movement to free the core for application logic. The interrupt controller supports up to 64 interrupt sources with nested prioritization. Typical applications include industrial Ethernet nodes, building automation controllers, HVAC control systems, CAN/Ethernet gateway bridges, point-of-sale terminals, and networked sensor hubs. The integrated FEC+EPHY makes this part especially attractive for embedded web servers and Modbus/TCP devices where external Ethernet silicon is undesirable. When designing with this part, consider that it is NRND. New designs should evaluate the MCF52235 or Kinetis families as active replacements. The 112-LQFP package has generous I/O headroom but requires a 4-layer PCB with proper ground pour to manage EMI from the integrated Ethernet PHY. Crystal selection (25 MHz reference) is critical for IEEE 802.3 timing compliance. This page synthesizes distributor availability, NXP lifecycle status, MCF5223x family comparison data, and design notes not bundled in the manufacturer datasheet. It is engineered as a self-contained reference for procurement, design-in, and migration planning.

Key features include an integrated 10/100 Ethernet MAC with MII/RMII PHY interface, USB 2.0 full-speed device/host with on-chip transceiver, CAN 2.0B controller, three UARTs (one with IrDA), two I2C ports, one QSPI, a 12-bit ADC (8 channels), four 32-bit timers, plus a 4-channel DMA. The device operates from a single 3.0V to 3.6V supply and is specified over the industrial -40C to +85C temperature range. The MAPBGA-121 package uses a 0.8mm ball pitch in a 12x12mm outline. While compact, the BGA package requires reflow assembly with X-ray inspection for quality control and typically uses a 4-layer PCB with via-in-pad or dog-bone fanouts for reliable solder joint formation. Typical applications include industrial Ethernet gateways, building automation controllers, CAN-based factory nodes, point-of-sale (POS) terminals, and networked sensor hubs that require deterministic real-time control with on-chip wired connectivity. Designers pair this MCU with external PHYs (e.g., DP83848 for Ethernet), CAN transceivers (e.g., TJA1050), and voltage regulators such as the NXP MC34717 or NCP1117 for the 3.3V core rail. Design consideration: When using the on-chip Ethernet MAC, route the MII/RMII traces as 50-ohm controlled-impedance lines with length matching within 50 mils. Place the external PHY within 6 inches of the MAC to keep MII signal integrity within IEEE 802.3 specification. Decouple each VDD ball pair with 100nF X7R ceramic plus a bulk 4.7uF tantalum, located within 2mm of the package.

The integrated hardware encryption block supports DES, 3DES, AES, and MD5/SHA-1 hashing, offloading secure handshake computation from the CPU. The 144-LQFP package exposes the full external bus and most peripheral pins, enabling maximum I/O flexibility for gateway and bridge designs. The ColdFire V2 core executes most instructions in a single cycle at 66 MHz, with an enhanced Multiply-Accumulate (EMAC) unit accelerating DSP-style signal processing tasks. The on-chip voltage regulator and low-power modes (Stop, Wait, Doze) reduce quiescent current for energy-constrained deployments. Free MQX RTOS support from NXP further simplifies firmware development for deterministic multi-tasking. Typical applications include industrial Ethernet gateways, building automation controllers, USB-to-CAN protocol bridges, smart metering data concentrators, and serial-to-Ethernet server modules. Designers commonly pair it with external PHYs for Ethernet and PHY/ transceiver ICs for CAN isolation. When designing with this part, evaluate thermal dissipation: at full 66 MHz operation the typical core supply current is in the tens of mA range, well within the LQFP-144 thermal envelope. Confirm RoHS and NRND status with the supplier when sourcing for long-lifecycle industrial SKUs.
