MCF52258CAG66 - ColdFire V2 32-bit MCU 512KB Flash 144-LQFP | NXP
MPN: MCF52258CAG66 ✗ Cuối đờiMCF52258CAG66 Tóm tắt
A ColdFire V2 microcontroller is a 32-bit embedded processor derived from the original Freescale (now NXP) 68k architecture lineage, optimized for low power consumption and deterministic real-time response. ColdFire MCUs belong to the broader 32-bit microcontroller category which sits in the hierarchy MCU -> embedded processor -> semiconductor device. The V2 variant uses a Variable-Length RISC encoding (ColdFire ISA-B) that achieves ARM-class code density at lower MHz, well suited to networked appliances and protocol bridging workloads.
Key features of the MCF52258CAG66 include 64KB SRAM, a 12-bit ADC with up to 8 analog input channels, four 32-bit timer/PWM units, three UARTs, two I2C controllers, and an external bus interface for memory expansion. 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.

Ứng dụng tiêu biểu
MCF52258CAG66 phù hợp cho 7 Áp dụngs: Industrial Ethernet Gateway, USB-to-CAN Protocol Bridge, Smart Metering Data Concentrator, Building Automation Controller, Serial-to-Ethernet Server Module, Industrial Motor Control Node, Point-of-Sale Terminal Controller.
Industrial Ethernet Gateway
The MCF52258CAG66's integrated 10/100 Ethernet MAC with MII/RMII support makes it ideal for industrial Ethernet gateways that bridge Modbus TCP, EtherNet/IP, or PROFINET to fieldbus networks. At 66 MHz the ColdFire V2 core runs a full TCP/IP stack plus protocol translation with cycle budget to spare. The 64KB SRAM accommodates socket buffers and the 512KB Flash holds TLS credential stores. Hardware AES acceleration offloads handshake computation. Pairing with a LAN8720A RMII PHY and external isolation transformer yields a complete industrial gateway node.
Được đề xuất
USB-to-CAN Protocol Bridge
Bridging USB 2.0 Full-Speed OTG to CAN 2.0B is a canonical use case for the MCF52258CAG66. The on-chip USB OTG controller plus dedicated CAN module eliminate external bridges. The 66 MHz ColdFire V2 core sustains 1 Mbps CAN throughput while serving the USB CDC stack. With 512KB Flash there is room for vendor-specific frame translation tables and diagnostic handlers. Galvanic isolation on the CAN side uses an external transceiver such as the TJA1050 or ISO1050.
Được đề xuất
Smart Metering Data Concentrator
Smart metering concentrators aggregate data from multiple electricity, water, or gas meters over M-Bus, RS-485, or wireless links. The MCF52258CAG66 fits as the central controller with its three UARTs, dual I2C controllers, and Ethernet for backhaul. The 12-bit ADC handles analog sensor calibration, and the on-chip crypto block secures AMI communications. NXP-provided MQX RTOS support enables deterministic multi-tasking for parallel meter polling and uplink aggregation.
Được đề xuất
Building Automation Controller
Building automation controllers consolidate HVAC, lighting, access control, and elevator subsystems over BACnet, LonWorks, or KNX. The MCF52258CAG66's blend of Ethernet, CAN, UARTs, and timers/PWM aligns with multi-protocol demand. The ColdFire V2 core executes BACnet/IP and translation logic at 66 MHz, while 64KB SRAM supports buffering of multiple concurrent subsystem flows. Hardware AES protects credential and audit-log traffic.
Được đề xuất
Serial-to-Ethernet Server Module
Serial-to-Ethernet server modules transparently bridge RS-232/RS-485 devices to Ethernet networks, a classic use case for the MCF52258CAG66. With three UARTs and an integrated Ethernet MAC, a single chip implements the entire server path. At 66 MHz a ColdFire V2 core can sustain multiple concurrent TCP/UDP sockets while queuing serial traffic. The 144-LQFP package provides generous GPIO for flow-control and status LEDs.
Được đề xuất
Industrial Motor Control Node
Distributed motor control nodes use the MCF52258CAG66 for CAN-linked command arbitration while delegating actual PWM to gate drivers. The four 32-bit timer/PWM units handle quadrature decoding and base-rate PWM, while the CAN 2.0B interface delivers deterministic command-rate messaging. The 12-bit ADC samples current and voltage feedback for closed-loop regulation. Hardware AES secures parameter updates from the controller.
Được đề xuất
Point-of-Sale Terminal Controller
POS terminal controllers require secure transaction processing, multi-peripheral coordination, and reliable Ethernet backhaul. The MCF52258CAG66 integrates all three: hardware AES for PIN encryption, USB OTG for peripheral connectivity, and 10/100 Ethernet for transaction upload. The 512KB Flash accommodates EMV stack and contactless kernel plus custom UI. The 144-LQFP package supports extensive peripheral expansion.

Ghi chú thiết kế
The MCF52258CAG66 integrates an on-chip voltage regulator requiring only a single external 3.3V supply; the internal core rail is generated on-die. Decouple the VDD/VSS pairs with a 100 nF ceramic capacitor as close to each pin cluster as possible, with a bulk 10 uF tantalum near the package. USB VDDA (pin 27) needs its own filtered ferrite bead-isolated supply and a 1 uF + 100 nF pair; sharing USB analog with digital VDD introduces jitter and degrades USB signal integrity.
At 66 MHz full activity with peripherals enabled, the ColdFire V2 core draws approximately 80 mA from the 1.5V internal rail, plus I/O current up to 30 mA on 3.3V. Total package dissipation stays well below 1 W in normal operation; the 144-LQFP has ample copper area to stay within 100 C/W theta_JA on standard 4-layer FR4. Ensure the PCB thermal pad layout includes a 0.5 oz copper pour under the package body to spread heat evenly.
Route Ethernet MII/RMII traces as matched-length differential pairs within 50 mil tolerance to the external PHY. Keep USB DP/DM as 90 ohm differential with no splits, and route the crystal traces (XTAL/EXTAL) within 10 mm of the MCU with a ground guard ring. Place the external bus address/data lines on adjacent layers with continuous ground reference to avoid crosstalk on the parallel bus at high speeds.
Do not leave the TRST pin floating; either tie it low through a 10 kohm resistor for normal operation, or drive it from the BDM debugger. Incorrect TRST handling is the most common BDM debug failure mode on ColdFire designs. Also verify the boot mode configuration pins (BMODx) at reset to ensure correct flash boot versus external ROM boot - misconfiguring these latches prevents firmware from starting.
