MCF52211CAF80 - ColdFire V2 32-bit MCU 80MHz 128KB | NXP
MPN： MCF52211CAF80 ✗ 停產MCF52211CAF80 概覽
A microcontroller (MCU) is a single integrated circuit that combines a processor core, memory, and peripherals into one chip, forming the lowest programmable layer of the embedded systems hierarchy: MCU -> processor -> computing system. The ColdFire V2 core is a reduced instruction set computing (RISC) architecture originally developed by Freescale Semiconductor, now part of NXP, widely used in cost-sensitive industrial and consumer embedded designs.
Key features of the MCF5221X family include integrated USB OTG for device or host operation, up to three UARTs, one serial peripheral interface (SPI), and two I2C interfaces, enabling easy connection to external systems. The MCF52211CAF80 provides 63 general-purpose I/O lines and operates from a single 3.3V supply.
Technically, the device is based on the cost-efficient, low-power ColdFire V2 platform with a 32-bit data bus width, CMOS process technology, and on-chip Flash eliminating external program memory in many designs. The USB OTG controller supports both host and peripheral roles, useful for USB-connected instruments and field-updatable devices.
Typical applications include industrial control panels, USB-enabled instruments and data loggers, building automation nodes, and legacy embedded systems where the ColdFire ecosystem and CodeWarrior toolchain remain in use.
Design consideration: because this part is End of Life per the NXP product page, new designs should evaluate pin-compatible MCF5221X family members or plan a long-term sourcing strategy through authorized excess-inventory channels such as Rochester Electronics.

典型應用
MCF52211CAF80 適用於 6 應用s: Industrial Control Panels, USB-Enabled Instruments and Data Loggers, Building Automation Nodes, Legacy Embedded System Sustaining Production, Point-of-Sale and Peripheral Controllers, Medical Device Service and Legacy Equipment.
Industrial Control Panels
The MCF52211CAF80 fits industrial control panel designs where a 32-bit ColdFire V2 core at 80 MHz, 128 KB of on-chip Flash, and abundant serial connectivity are required. Up to three UARTs allow simultaneous communication with HMI displays, motor drives, and modems, while the single SPI and two I2C interfaces connect ADCs, EEPROMs, and I/O expanders. The 63 GPIO lines directly drive relays, indicators, and keypad matrices, and the 3.3V supply simplifies integration with modern logic. Because the part is EOL, use it in sustaining production of proven designs, sourcing remaining stock through Rochester Electronics or authorized excess channels, and maintain a migration plan to a current NXP MCU family for future board revisions.

USB-Enabled Instruments and Data Loggers
The integrated USB On-the-Go (OTG) controller is the defining feature of the MCF5221x family, making the MCF52211CAF80 well suited to bench instruments, data loggers, and field devices that must appear as a USB device to a PC or act as a USB host to a memory stick. Operating from a single 3.3V rail, the OTG peripheral handles device and host roles, enabling field firmware updates and local data offload without a separate USB bridge chip. At 80 MHz, the ColdFire V2 core sustains USB transaction handling alongside 128 KB of resident application firmware. Combine the MCU with a precision ADC such as the MAX187 for the measurement front end and use one of the three UARTs for a service/debug port.
推薦
Building Automation Nodes
Building automation controllers benefit from the MCF52211CAF80's dual I2C buses, SPI port, and multiple UARTs: one I2C bus can serve environmental sensors while a second serves EEPROMs or RTCs, and UARTs connect to RS-485 transceivers for fieldbus networking. The 63 GPIO lines interface occupancy sensors, dampers, and relays, and the 80 MHz ColdFire V2 core runs protocol stacks within the 128 KB Flash footprint for compact node firmware. The USB OTG port provides a commissioning and configuration interface to a laptop or USB service key. Note the EOL status: new node designs should evaluate current NXP families, while existing installations can be sustained with remaining authorized stock.
推薦
Legacy Embedded System Sustaining Production
A primary use of the MCF52211CAF80 today is sustaining production of legacy embedded systems originally designed on the Freescale ColdFire platform. CodeWarrior toolchains, ColdFire BDM debug hardware, and existing firmware bases remain functional, and the 100-LQFP (14 x 14 mm) footprint is unchanged across the family, so replacement units drop onto existing PCBs. With 80 MHz performance, 128 KB Flash, USB OTG, three UARTs, SPI, and two I2C, the part preserves all original functional requirements without redesign. Procurement should secure last-time-buy quantities through Rochester Electronics and other authorized excess distributors listed on the NXP EOL notice, and document a redesign path toward a currently supported NXP MCU family.
推薦
Point-of-Sale and Peripheral Controllers
Point-of-sale terminals, receipt printers, and barcode peripherals historically used MCF5221x-class MCUs because USB OTG provides direct connectivity to host POS terminals in either device or host role, while the three UARTs handle printers, mag-stripe readers, and accessory ports. The 80 MHz ColdFire V2 core processes ESC/POS formatting and USB transactions within 128 KB of on-chip Flash, and 63 GPIO lines drive stepper motors, sensors, and indicator LEDs from a single 3.3V supply. For sustaining these products, the 100-LQFP package supports standard SMT assembly. Because the part is End of Life per NXP, new POS designs should target NXP's currently active MCU portfolios, reserving this part for spares and continuing builds.
推薦
Medical Device Service and Legacy Equipment
Installed-base medical equipment such as patient-data terminals and portable diagnostic instruments built on ColdFire architecture relies on the MCF52211CAF80 for service replacements. The 32-bit 80 MHz core, 128 KB Flash, USB OTG for data export, and dual I2C plus SPI for sensor interfaces replicate the original design requirements exactly, and the tray-packaged 100-LQFP part allows rework and board-level replacement in regulated environments with full traceability through authorized distributors such as Rochester Electronics. Precision analog front ends in these instruments typically pair the MCU with ADCs like the MAX188 or CS5531. Verify regulatory change-control procedures before substituting any alternative part, even within the same family.

設計說明
The MCF52211CAF80 is End of Life per the NXP product page. Before committing any design change, secure last-time-buy quantities through Rochester Electronics (listed on DigiKey under Freescale branding) and document a migration path. Do not assume same-package parts from the cross-reference listings (e.g., MKV46F256VLL16, FS32K146HAT0VLLT) are pin-to-pin compatible - they use different cores and pinouts and require PCB redesign.
The device operates from a single 3.3V supply. Provide local decoupling (100 nF ceramic per VDD/VDDA pair plus bulk capacitance) at the 100-LQFP supply pins, and keep the analog supply filtered separately from the digital rail to preserve USB and oscillator performance. Systems interfacing to legacy 5V peripherals must use level shifters since the ColdFire I/O is not 5V tolerant.
For the USB OTG port, route D+/D- as a matched 90-ohm differential pair with length matching within a few millimeters and place the USB connector termination components within 25 mm of the LQFP pins. Follow the layout guidance in the NXP MCF52211 data sheet (nxp.com/docs/en/data-sheet/MCF52211.pdf) for oscillator and USB placement to pass signal-integrity checks.
