MCF52264AF80 - 80MHz ColdFire V2 MCU, 256KB Flash | NXP
MPN: MCF52264AF80 ✗ Cuối đờiMCF52264AF80 Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip embedded processor that integrates a CPU core, program memory, data memory, and multiple communication and control peripherals on one silicon die. MCUs sit at the device level of the embedded systems hierarchy - below application processors and above simple 8-bit controllers - and the MCF5225x family from NXP (originally Freescale Semiconductor) targets industrial embedded control and networked peripheral coordination.
Key features of the MCF52264AF80 include the superscalar ColdFire V2 core delivering up to 76 Dhrystone 2.1 MIPS at 80 MHz, 256KB (256K x 8) of Flash program memory with in-system programming support, an on-chip USB module, an Ethernet MAC, a CAN controller, and the availability of the complete MQX RTOS software at no additional cost. These integrated communication interfaces eliminate external controllers in multi-protocol industrial designs.
Technically, the MCF5225x family devices are highly integrated single-chip solutions combining the ColdFire V2 microarchitecture with a rich peripheral set including UARTs, timers, DMA, ADC, and the encryption and connectivity functions noted in the family overview. The 3.3V supply domain and 80 MHz maximum clock support deterministic embedded control with real-time response.
Typical applications include industrial automation nodes with CAN and Ethernet connectivity, USB-enabled field instruments, gateways bridging CAN to Ethernet, and general embedded control systems requiring 32-bit performance. The 0C to +105C operating range covers most industrial environments.
Design consideration: this part is listed by NXP as NRND (Not Recommended for New Designs), so new designs should evaluate newer NXP MCU families or verified alternatives, while existing designs can continue sourcing for maintenance.

Ứng dụng tiêu biểu
MCF52264AF80 phù hợp cho 6 Áp dụngs: Industrial Automation Nodes, CAN-to-Ethernet Gateways, USB Field Instruments, Embedded Control Systems, Networked Peripherals and Encryption-Enabled Devices, Legacy System Maintenance and Last-Time-Buy Programs.
Industrial Automation Nodes
The MCF52264AF80 fits factory-floor control and coordination nodes because its ColdFire V2 core at 80 MHz delivers deterministic 32-bit execution while the on-chip CAN 2.0B controller and 10/100 Ethernet MAC handle both field-level and backhaul communication without external controllers. In a typical automation node, the MCU services CAN traffic to actuators and sensors while the Ethernet MAC reports upstream to a supervisory system, with the 0C to +105C temperature range covering electrical cabinets and floor-level enclosures. The no-cost MQX RTOS from NXP provides a multitasking foundation for protocol stacking. Because the part is NRND, new industrial designs should qualify the same-footprint MCF52259CAG80 variant in parallel.

CAN-to-Ethernet Gateways
Protocol bridging between CAN 2.0B fieldbuses and 10/100 Ethernet backbones is a natural fit for the MCF52264AF80, since both controllers are integrated on the die. A gateway implemented on this MCU buffers CAN frames in on-chip SRAM, performs protocol translation in the ColdFire V2 core, and streams data over the Ethernet MAC, eliminating a two-chip design and the associated board area. The 80 MHz core clock provides enough throughput for moderate message rates with the MQX RTOS managing concurrent stack tasks. Designers should budget DMA channels and interrupt latency carefully at high CAN frame rates, and verify Flash headroom since the 256KB array must hold both protocol stacks.

USB Field Instruments
Portable and benchtop field instruments benefit from the MCF52264AF80's integrated USB 2.0 Full-Speed device/host capability, which allows direct connection to PCs for configuration, data logging, and firmware updates without a dedicated USB interface chip. The 3.3V supply domain matches common instrument logic levels, and the 256KB Flash array accommodates measurement firmware plus a USB communication stack under the MQX RTOS. Because the ColdFire V2 core runs at 80 MHz, acquisition loops and USB servicing coexist with predictable timing. For instruments needing local storage or richer connectivity, the same-footprint 52259 variant doubles program memory, simplifying a later upgrade without PCB rework.

Embedded Control Systems
General-purpose embedded control - motor supervision, power monitoring, process sequencing - is well served by the MCF52264AF80's combination of a 32-bit superscalar ColdFire V2 core, ample 256KB Flash, and integrated communication peripherals. The core's deterministic interrupt response supports real-time control loops, while UARTs, timers, and DMA offload routine I/O from software. The device runs from a single 3.3V rail, simplifying power design relative to multi-rail processors. Engineers choosing this MCU for new embedded control work should note the NRND designation and consider qualifying the MCF5225x family alternatives on this page, which share the identical 100-LQFP (14x14 mm) land pattern and 80 MHz performance class.

Networked Peripherals and Encryption-Enabled Devices
The MCF5225x family - including the MCF52264AF80 - was designed for highly integrated devices with on-chip USB, Ethernet, CAN and encryption functions, making it suitable for networked peripherals that require authenticated or encrypted communication. A networked peripheral can terminate its Ethernet link in hardware-adjacent MAC logic, run security routines on the ColdFire V2 core, and coordinate local I/O, all from one chip. The availability of the complete MQX RTOS at no additional cost shortens time-to-market for TCP/IP and security-aware applications. The 100-LQFP package's 14x14 mm footprint fits compact peripheral housings while remaining hand-solderable and inspectable for low-to-mid volume production.
Được đề xuất
Legacy System Maintenance and Last-Time-Buy Programs
A significant ongoing use of the MCF52264AF80 is sustaining deployed equipment originally designed around the MCF5225x family. Because NXP lists the part as NRND, maintenance engineering teams source it through remaining franchised stock at Mouser and DigiKey or via Rochester Electronics, the authorized aftermarket channel that supplies the Freescale-branded equivalent listed by DigiKey. Procurement teams should quantify remaining program lifetime and place consolidated last-time-buy orders, while firmware teams maintain builds against a same-footprint backup variant such as the MCF52259CAG80 so a board revision swap remains possible without mechanical or layout changes on the 100-LQFP footprint.

Ghi chú thiết kế
The MCF52264AF80 is NRND per NXP's official product page. Do not start new designs on this device. For existing designs, verify the exact ordering suffix against your board's temperature and speed grade requirements (the A and F80 suffixes define the grade and 80 MHz maximum), and confirm stock with both franchised distributors and Rochester Electronics before release. Keep firmware builds compilable for the MCF52259CAG80 so a same-footprint swap remains available if 256KB-variant supply ends.
The device operates from a single 3.3V supply. Estimate: at 80 MHz the ColdFire V2 core current is on the order of tens of milliamps (consult the MCF522XX family datasheet electrical characteristics table for the exact Idd value) - budget decoupling with 100 nF ceramics at each Vdd pin pair plus bulk capacitance near the regulator. The Ethernet and USB PHY supply pins require clean, well-bypassed rails to meet signal-quality requirements; follow the family reference manual power section for pin-group filtering.
For the 100-LQFP (14x14 mm) footprint, use a standard 0.5 mm pitch land pattern per IPC-7351 guidelines and place the USB differential pair and RMII/MII Ethernet traces as controlled-impedance differential/single-ended pairs per the family reference manual layout guidance. Keep CAN transceiver routing short and place a common-mode choke near the connector. Flash in-circuit programming requires the background debug connector to remain accessible for field updates and recovery of a locked device.
