MCF5213CAF80 - 32-bit ColdFire V2 MCU 80MHz 256KB | NXP
MPN： MCF5213CAF80 ✗ 停產MCF5213CAF80 概覽
A microcontroller integrates a processor core, program memory, data memory, and communication peripherals on a single die. Within the embedded-controller hierarchy, the MCF5213 sits in the 32-bit microprocessor segment: ColdFire V2 RISC core -> ColdFire family -> NXP (formerly Freescale) embedded MCU portfolio. Single-chip MCUs like the MCF5213 reduce board area and system cost versus a discrete CPU-plus-chipset solution.
Key features include the ColdFire V2 reduced instruction set computing (RISC) core delivering 80 MHz performance, up to 256 KB of near-single-access interleaved embedded flash, and up to 521 KB flash availability across the MCF521x family. Communication coverage is a highlight: three UARTs for medium-to-long-distance serial links, plus industry-standard serial peripherals for flexible system connectivity. The 3.0 V to 3.6 V single-supply operation and integrated power management target battery-conscious and industrial designs.
Technically, the ColdFire V2 architecture is a variable-length RISC instruction set descended from the Motorola 68000 family, optimized for code density - important when running C-compiled applications from on-chip flash. The interleaved flash memory organization enables near-single-cycle instruction fetches, sustaining core throughput at 80 MHz without external memory.
Typical applications include industrial control and factory automation nodes, medical monitoring instruments, and building/energy management systems, where a 32-bit MCU with abundant UART channels and flash capacity consolidates logic that previously required multiple chips.
Design consideration: because this part is classified NRND (Not Recommended for New Designs) by NXP, new designs should evaluate the MCF521xx successor families or pin-compatible alternatives; existing production lines should plan last-time-buy strategies.

典型應用
MCF5213CAF80 適用於 6 應用s: Industrial Control and Factory Automation, Medical Monitoring Instruments, Building and Energy Management Systems, Networked Serial Device Servers, Test and Measurement Equipment, Motor Control and Motion Panels.
Industrial Control and Factory Automation
The MCF5213CAF80 fits industrial control nodes because its 80 MHz ColdFire V2 core executes control loops and communication protocol stacks deterministically, while 256 KB of embedded flash holds firmware without external memory - reducing BOM cost and board area in control cabinets. Its three UARTs allow one chip to bridge an RS-485 field bus, a local HMI, and a maintenance console simultaneously. Placed as the main controller with UART lines isolated via transceivers, the single-chip architecture eliminates glue logic; the trade-off is verifying real-time deadlines at the bus clock, and since the part is NRND, new automation platforms should evaluate currently-supported successors while existing lines use it for sustaining builds.

Medical Monitoring Instruments
In patient monitors and diagnostic bench instruments, the MCF5213CAF80's 32-bit core handles signal acquisition and data formatting while its three UARTs stream measurement data to displays, printers, and hospital networks. The 256 KB flash accommodates calibration tables and protocol firmware from on-chip memory, and the MCF521x family's low-power single-chip design suits portable instrumentation where battery life matters. Typical usage pairs the MCU's UART with an isolated RS-232/RS-485 front end for galvanic patient isolation - a quantified benefit is consolidating processor, memory, and communications into one LQFP-100 device instead of a multi-chip CPU solution. Because the device is NRND, medical OEMs should secure last-time-buy stock before finalizing long-support-life products.
推薦
Building and Energy Management Systems
Building controllers and energy meters leverage the MCF5213CAF80's three UARTs to concentrate data from MODBUS meters, damper actuators, and SCADA uplinks on one chip, while the 80 MHz core runs scheduling and control logic with headroom. The family's stated positioning as a cost-effective, low-power single-chip solution maps directly to networked controller nodes deployed at scale, where per-unit cost multiplies across hundreds of points. The 256 KB flash supports BACnet-style stack images compiled from C. Field deployments typically run the MCU from a 24 V-derived 3.3 V rail with UART transceivers handling long cable runs; the single-chip consolidation reduces mean-time-between-failure contributors versus discrete CPU-plus-memory boards.
推薦
Networked Serial Device Servers
Serial-to-network gateways are a natural fit: the MCF5213CAF80's three UARTs can each service an independent serial device while the 32-bit core runs protocol translation firmware from 256 KB of interleaved flash with near-single-cycle fetches sustaining throughput. In a typical topology, UART0-2 connect to RS-232/485 device buses through transceivers, and the consolidated CPU handles framing, buffering, and forwarding. The benefit is deterministic serial servicing without external memory latency; the constraint is that this MCU has no integrated Ethernet MAC, so gateways pair it with an external controller or SPI/Ethernet bridge. NRND status again directs new gateway designs toward supported parts, while sustaining production can rely on current distributor stock of about 14,652 pieces at Heisener.
推薦
Test and Measurement Equipment
Bench instruments, data loggers, and panel meters use the MCF5213CAF80 as the system controller: the 80 MHz RISC core manages acquisition timing and front-panel interfaces, three UARTs handle PC connectivity, printer output, and module daisy-chaining, and the 256 KB flash stores configuration sets and logging tables on-chip. Interleaved flash enables near-single-access execution, keeping measurement loops consistent. Designers typically clock the core from the internal PLL and use timer-driven acquisition with UART streaming for unattended logging. The main trade-off versus newer Arm-based controllers is ecosystem support - toolchains remain available, but the NRND classification means new instrument platforms should choose actively-supported MCUs and reserve the MCF5213 for existing product maintenance.
推薦
Motor Control and Motion Panels
Motion and motor-control panels apply the MCF5213CAF80's deterministic 80 MHz ColdFire V2 core to closed-loop speed and position updates while UARTs link to drives, joystick interfaces, and host controllers. The single-chip flash architecture executes control routines with near-single-cycle fetches, supporting consistent loop periods; three UARTs separately serve a drive bus, a setpoint input, and diagnostics. Boards typically connect the MCU's GPIO to gate-driver or PWM-adjacent logic with optical isolation for power-stage separation, and the consolidated 100-LQFP device replaces multi-chip CPU memory subsystems common in legacy panels. Because the part is NRND, new motion platforms should target currently-supported MCUs, but this device remains a valid sustaining choice for installed-panel service boards.

- Trade-off: NRND lifecycle status (對比MCF52223CAF80)
設計說明
The MCF5213CAF80 is NRND per NXP's official product page. Do not start new designs on this part. For sustaining production, place a full last-time-buy with your distributor (Heisener reported about 14,652 pieces in stock as of 2026-10-18, but NRND stock is non-replenishing) and monitor NXP product change notices published on the part page for discontinuation announcements.
The 100-LQFP (14 x 14 mm) package has 0.5 mm pin pitch - use solder-mask-defined pads per IPC guidance in your fab's capability set and verify courtyard clearance for reflow routing. Pins are multiplexed (GPIO plus peripheral functions); finalize the pin function assignment table from the NXP reference manual before routing so UART and timer signals land on capable pins. Provide a solid ground plane under the device and decouple each supply pair with 100 nF ceramics placed within 2 mm of the pins.
Estimated: supply current scales with core frequency - migrating a design from MCF5213CAF80 (80 MHz) to MCF5213CAF66 (66 MHz) reduces dynamic core power roughly proportional to the 17.5% frequency reduction, in addition to saving cost. Confirm exact IDD figures against the electrical characteristics tables in the NXP MCF5213 datasheet for your voltage and temperature corner before finalizing the power budget; do not rely on family-typical values for battery-operated products.
At an 80 MHz bus, keep UART and external-bus trace lengths short and matched where possible, and series-terminate long lines (estimated 22-33 ohm resistors) to control ringing on 0.5 mm-pitch fanout. Since three UARTs may run concurrently, route the clock tree away from UART lines to minimize crosstalk-induced framing errors on longer cable runs.
