MCF5206FT25A - Coldfire V2 MPU, 32-Bit, 25MHz | NXP | 160-QFP
料号： MCF5206FT25A ✗ 停产MCF5206FT25A 概述
Background Knowledge: A microprocessor (MPU) is an integrated circuit that contains the central processing unit of a computer system but requires external program memory (ROM/Flash) and external RAM to operate, in contrast to a microcontroller (MCU) which integrates memory on-chip. The ColdFire architecture is a 32-bit RISC ISA derived from the Motorola 68000 family, designed to provide higher code density and lower cost than full M68K while remaining source-compatible at the assembly level. ColdFire V2 sits in the entry-level tier of the ColdFire roadmap, optimized for deterministic embedded control, replacing legacy 68K designs, and bridging to higher ColdFire V3/V4 cores.
Key features of the MCF5206FT25A include a 32-bit ColdFire V2 core, 25 MHz operating frequency, hardware multiply and divide, 8-bit I/O bus, a debug/module interface (BDM), an external oscillator input, and a 160-BQFP gull-wing surface-mount package that simplifies PCB layout with standard through-hole or reflow footprints on legacy industrial designs.
Technical depth: The MCF5206FT25A uses the ColdFire V2 integer pipeline, which supports 32-bit instructions and 16-/32-bit aligned operands. Peripherals typically integrated on this family include multiple UART channels, a 16-bit timer, a system integration module, chip selects with wait-state insertion, DRAM/SDRAM support, and a programmable interrupt controller, although this older 160-BQFP variant exposes a subset focused on industrial control. Power is supplied by a 5 V rail (with internal regulators for the core), and the device is specified for the commercial temperature grade.
Typical applications include industrial PLCs and machine controllers, factory automation HMIs, motor and motion-control boards, point-of-sale terminals, networking edge devices (routers/bridges), and legacy industrial equipment retrofits. The 13-MIPS throughput and 32-bit ColdFire ISA make it well suited to deterministic control loops where C-language programmability and code density outperform older 8/16-bit microcontrollers.
When designing with this part, ensure external program memory (Flash) and SRAM are correctly mapped via the chip selects, that the BDM debug header is brought out for development, and that the 25 MHz oscillator source uses a crystal or clock generator matched to the datasheet load capacitance. Heat sinking is not required for the 160-BQFP at typical industrial loads because the CMOS process keeps dissipation in the single-watt range.
This page consolidates distributor pricing, drop-in compatible alternatives in the same 160-BQFP footprint, and practical design notes that complement the manufacturer datasheet's pinout chapter.

典型应用
MCF5206FT25A 适用于 7 应用s: Industrial PLC / Machine Controller, HMI / Factory Touch Display, Point-of-Sale Terminal, Industrial Networking Bridge / Router, Motor / Motion Controller, Legacy Industrial Printer / Scanner, Embedded Industrial Gateway / Sensor Aggregator.
Industrial PLC / Machine Controller
The MCF5206FT25A is well matched to industrial PLC and machine-controller boards where deterministic real-time response and C-language programmability replace older 8/16-bit microcontrollers. Its 32-bit ColdFire V2 core delivers 13 MIPS sustained throughput at 25 MHz, easily handling scan loops for digital I/O, structured-text ladder logic, and PID control updates within 1 ms scan budgets. External Flash on the address/data bus stores the firmware, while external SRAM serves the runtime stack. ColdFire V2's 32-bit aligned operands allow 32-bit floating-point emulators and motor-position arithmetic without code-size penalties, and the 160-BQFP package is ruggedized for industrial environments. Engineers must verify chip-select timing and add a BDM header (in-circuit debug) for development access.
推荐
HMI / Factory Touch Display
Human-machine interface (HMI) terminals with graphical LCDs and touch overlay benefit from the MCF5206FT25A's 32-bit address space, which can comfortably address large frame buffers in external SRAM or directly on the parallel bus without external memory-mapped logic. ColdFire V2's code density enables compact TCP/IP stacks, Modbus RTU, and CANopen transports when paired with an external CAN controller. The 8 dedicated I/O lines feed discrete control signals to drive end-stops, relays, or indicator LEDs. Industrial temperature grade and 160-BQFP gull-wing leads survive factory-floor vibration profiles typical of controller enclosures. Engineers adding a graphical LCD must verify DMA and wait-state assignments on the chip selects.
推荐
Point-of-Sale Terminal
Legacy point-of-sale (POS) terminals often replace 8-bit MCUs with the MCF5206FT25A to gain 32-bit arithmetic for tax calculation, encryption offload (SHA-1/MD5 in firmware), and faster receipt-printer throughput. The 13-MIPS ColdFire V2 ISA executes C-based payment stacks comfortably, and the ROMless design lets integrators reserve protected Flash regions for cryptographic key storage and tamper detection. The 160-BQFP package at 28x28 mm is compatible with mature PCB footprints designed two decades ago. POS engineers should pair the MPU with a hardware TRNG and a secure key-storage companion to satisfy PCI PTS separation requirements.
推荐
Industrial Networking Bridge / Router
Edge networking bridges, protocol converters, and industrial Ethernet-to-serial gateways map naturally to the MCF5206FT25A's simultaneous UART and external bus support. ColdFire V2's deterministic interrupt response handles real-time industrial protocols such as Modbus, BACnet, EtherNet/IP, or PROFINET, while an external Ethernet controller supplies the PHY interface. The ROMless architecture lets engineers store firmware in a large external Flash (typically 1-2 MB), enabling full Modbus/TCP stacks. The 160-BQFP package fits legacy PC-104 form-factor industrial SBCs. Network engineers must verify timing budgets on the chip selects when extending the bus to additional peripherals.
推荐
Motor / Motion Controller
Stepper and servo motor control boards rely on deterministic ISR latency, and the MCF5206FT25A's ColdFire V2 core delivers predictable interrupt response on the order of 5-10 µs. Position-loop computation (encoder counts, ramping, torque profiles) runs comfortably in 32-bit integer arithmetic at 13 MIPS. External PWM generators or pulse-and-direction drivers receive commands from the chip selects or GPIO; current sensing is sampled by an external ADC. The 160-BQFP industrial package survives the vibration and thermal environments of motor enclosures. Motion-control designers should monitor junction temperature under sustained full-load stepping because the LQFP package has moderate thermal resistance.
推荐
Legacy Industrial Printer / Scanner
Label printers, industrial barcode scanners, and embedded thermal printers transitioning from 8-bit MCUs to 32-bit cores benefit from the MCF5206FT25A's ROMless architecture with a large address space, allowing firmware updates to add modern protocols (USB, Ethernet) and richer LCD UIs. ColdFire V2's 32-bit multiply accelerates Reed-Solomon CRC and barcode error correction. The 160-BQFP 28x28 mm package fits the legacy mechanical chassis of industrial printers. System designers must add external DMA glue or use the MPU's chip-select handshake to feed the print engine at burst speeds above 1 MB/s without dropping characters.
推荐
Embedded Industrial Gateway / Sensor Aggregator
Modular industrial gateways aggregating RS-485, RS-232, CAN, and analog sensor data benefit from the MCF5206FT25A's 25 MHz throughput, parallel external bus, and 8 dedicated I/O lines. ColdFire V2's code density is sufficient for a small embedded HTTP/TLS server frontend to expose the aggregated data to the cloud. External SRAM attached to the address/data bus buffers sensor samples and TLS handshake traffic. The 160-BQFP industrial-grade package meets legacy DIN-rail sub-assembly requirements. Gateway engineers should validate end-to-end throughput with realistic sensor payload rates to confirm the polling loop stays within scan budgets under TLS load.

设计说明
Estimated: The MCF5206FT25A digital supply rail draws approximately 1 mA/MHz of core activity plus IO switching current. At 25 MHz running from a 5 V rail the typical dissipation is in the 100-200 mW range. Use a 100 nF decoupling cap on each VCC pin pair plus a single 10 µF bulk cap near the IC. Tie unused voltage pins (e.g., PLL VCC) to the same 5 V rail through a ferrite bead to avoid supply-noise injection into the internal clock multiplier.
The 160-BQFP package's 0.65 mm lead pitch and 28x28 mm footprint require a 4-layer PCB for clean external-bus routing on address (A23-A0), data (D31-D0), and chip-select signals. Place the external program Flash and SRAM on the same routing layer directly adjacent to the MCF5206FT25A to keep bus traces under 50 mm and to minimize propagation skew between control signals and the data bus. Provide a dedicated VCC/GND pair under the package center for the internal core regulator.
Do not connect RESET without proper POR/reset IC supervision; the MCF5206FT25A reset line requires 5 ms minimum to allow the internal PLL to stabilize. Avoid leaving the BDM (DSI/DSO) pins floating if the BDM header is not populated - the part has no internal pull-ups on these pins, and stray capacitance on a multi-drop development environment can trigger spurious background-debug responses.
If the external bus runs faster than 20 MHz equivalent (i.e., from a faster drop-in alternative like MCF5206FT33), insert 33 Ω series-termination resistors on each data/address/control line near the MPU. The 160-BQFP's inductive leads contribute ringing above 15 MHz reflection events; series damping at the source is the cheapest mitigation.
合规信息
RoHS compliant per NXP product page and Rochester Electronics listing. Halogen-free status not explicitly published for this N/RND variant; manufacturing takes place before 2010, so halogen-free is reported as 'unknown'. AEC-Q100 does not apply because this is an industrial-grade MPU, not an automotive-qualified device.
