MCF5206AB16A - ColdFire V2 MPU 16MHz 32-Bit 160-QFP | NXP
部品番号: MCF5206AB16A ✗ 生産終了MCF5206AB16A 概要
A microprocessor (MPU) is an integrated circuit that contains the central processing unit, register file, and on-chip memory peripherals necessary to execute software fetched from external storage. The ColdFire V2 architecture is a streamlined 32-bit variable-length instruction set derived from the original Motorola 68000 family, optimized for embedded control and offering higher code density than typical RISC cores. The MCF520x line of MPUs uses this ColdFire V2 core and positions itself as a low-cost bridge between legacy 68k designs and modern 32-bit embedded systems.
Key features of the MCF5206AB16A include a 16 MHz ColdFire V2 32-bit CPU, 512 bytes of on-chip SRAM, ROMless operation for flexible boot configuration, an external oscillator input, and a 160-QFP package measuring 28x28 mm. The part operates from a single supply and includes 8 programmable I/O lines plus integrated peripherals typical of the ColdFire MCF5206 series such as timers, serial interfaces, and a system integration module.
The MCF5206 architecture combines the ColdFire V2 core with a unified 32-bit address and data bus structure. Designers benefit from deterministic instruction execution, low interrupt latency, and an easy migration path from older 68k-based designs. The absence of internal flash means firmware is held in external ROM or flash, simplifying memory qualification and allowing larger program images than on-chip storage would permit.
Typical applications for the MCF5206AB16A include industrial control, factory automation, networked equipment controllers, building automation, motor control hubs, and legacy 68k retrofit designs. Designers also use the MCF5206 in communications equipment where a deterministic 32-bit controller is needed for protocol stacks and supervisory tasks.
When using this device, ensure the external oscillator circuit meets the ColdFire V2 AC timing requirements and that address/data bus loading is properly terminated. The 160-QFP footprint allows rework and inspection with conventional surface-mount tools, simplifying prototypes and field repair.

主な用途
MCF5206AB16A の用途: 6 件s: Industrial Control and Automation, Building Automation and HVAC Controllers, Legacy 68k Retrofit Designs, Communications Protocol Bridges, Motor Control and Drive Supervisors, Test Equipment and Instrumentation Front-Ends.
Industrial Control and Automation
The MCF5206AB16A's deterministic ColdFire V2 32-bit core at 16 MHz and external bus interface make it well suited to industrial controllers driving sensors, actuators, and motor inverters. Its 160-QFP package offers straightforward PCB layout for backplanes with multiple bus loads. With 512 bytes of on-chip SRAM for fast interrupt handling and external flash for program storage, the part handles PLC scan loops and supervisory tasks. Designers pair it with isolated I/O and CAN or RS-485 transceivers to build machine controllers with deterministic timing.
おすすめ
Building Automation and HVAC Controllers
Building automation systems require reliable 32-bit controllers that run continuously for years. The MCF5206AB16A fits this role thanks to its 16 MHz ColdFire V2 core, ROMless architecture for flexible firmware updates, and a 160-QFP package suitable for industrial-rated PCBs. The external bus can address up to several megabytes of flash for HVAC control firmware and user-interface code. With the ColdFire BDM interface, integrators can perform field updates through the same debug port used during production testing.
おすすめ
Legacy 68k Retrofit Designs
Designers migrating from older 68k-based boards to a 32-bit ColdFire V2 controller can drop the MCF5206AB16A into existing 160-QFP layouts with minimal firmware rewrite. The ColdFire V2 core preserves 68k-like instruction semantics while delivering higher code density and lower power. The 16 MHz clock matches typical 68k retrofit performance envelopes, and the external bus interface maps cleanly to legacy memory devices. This makes the part a low-risk stepping stone for in-service equipment upgrades.
おすすめ
Communications Protocol Bridges
Protocol bridges between industrial fieldbuses (CAN, RS-485, RS-232) and backhaul networks benefit from the MCF5206AB16A's deterministic 16 MHz core and external memory bus. The ColdFire V2 architecture executes protocol stacks efficiently while the 160-QFP package supports dense pin-out designs with multiple serial channels. With external flash for protocol tables and the BDM port for in-field stack updates, the part suits substation gateways and serial concentrator designs.
おすすめ
Motor Control and Drive Supervisors
Motor drives use supervisory MCUs to manage start-up sequencing, fault detection, and fieldbus communication alongside the actual inverter control loops. The MCF5206AB16A handles these supervisory tasks at 16 MHz with predictable interrupt latency and an external bus that connects to gate drivers and A/D converters. The 160-QFP package withstands industrial thermal environments and gives design engineers ample GPIO for status LEDs, encoder feedback, and emergency-stop wiring.
おすすめ
Test Equipment and Instrumentation Front-Ends
Bench-top and rack-mounted test equipment use 32-bit controllers like the MCF5206AB16A to manage user interfaces, data acquisition sequencing, and GPIB or Ethernet connectivity. The external bus supports expansion memory for waveform captures and calibration tables, while the BDM interface simplifies factory calibration. With 16 MHz of deterministic throughput, the part coordinates test sequences and serial-protocol peripherals in a single compact 160-QFP footprint ideal for front-panel PCBs.

設計ノート
Decouple the VCC pins on the 160-QFP package with a 0.1 uF ceramic capacitor placed within 5 mm of each power pin pair, plus a bulk 10 uF tantalum or ceramic capacitor near the IC. Estimated: with all I/O switching at 16 MHz, expected core current is approximately 100 mA typical for the ColdFire V2 core, but always verify against the manufacturer datasheet for final values. Ground returns should use a contiguous ground plane beneath the device to minimize supply bounce.
Route the address and data buses with matched trace lengths to keep skew below the ColdFire V2 setup/hold budgets, especially at the top bus speeds. Place external memory (ROM/flash and SRAM) as close to the 160-QFP part as possible and isolate the external clock trace from the bus lines. Use guard traces or an inner ground layer around the oscillator section to suppress EMI from the 16 MHz fundamental and its harmonics.
Do not exceed the 16 MHz rated clock of the MCF5206AB16A - using this part beyond its rated speed risks bus timing violations and long-term reliability damage. Do not forget external bus wait-state configuration for slow ROM/flash; an incorrectly set number of wait states will cause code fetch failures. Always wire the RESET pin through a supervisory reset IC and include proper decoupling on the BDM pins if debugging is required.
