MCF5206ECFT40 - ColdFire V2 MPU, 40MHz, 32-Bit, 160-QFP | NXP
Référence : MCF5206ECFT40 ✗ Fin de vieMCF5206ECFT40 Présentation
A microprocessor (MPU) is a CPU-centric integrated circuit that fetches and executes instructions from external memory. Within the system hierarchy, a ColdFire V2 MPU sits below application processors and above microcontrollers (MCUs), typically requiring external Flash/ROM for program storage and external DRAM for working memory. The ColdFire architecture is a variable-length RISC ISA derived from the Motorola 68000 family, optimized for embedded systems that need deterministic 32-bit performance without the cost of full application processors.
Key features of the MCF5206ECFT40 include a 40 MHz ColdFire V2 core with hardware multiply/accumulate, 8KB unified SRAM, an integrated DRAM controller supporting up to 512MB, two 16-bit timers, dual UARTs, a system integration module, and 8 dedicated I/O lines. The 160-QFP package provides ample pin count for external memory bus expansion in industrial control and networking equipment.
Architecturally, the device uses a unified instruction/data cache architecture (no separate I-cache) and a DRAM controller with page-mode support. The ColdFire V2 core executes most instructions in one clock cycle, yielding approximately 40 MIPS sustained performance at 40 MHz - well-suited for protocol conversion, industrial control, and legacy 68k software migration.
Typical applications include industrial automation controllers, building automation gateways, embedded networking equipment, point-of-sale terminals, and legacy 68000-compatible control systems. Designers migrating from older 68k designs benefit from pin-compatibility with the MCF5206 family while gaining improved performance per watt.
When designing with this part, verify that your toolchain supports the ColdFire V2 ISA (GCC coldfire target or NXP CodeWarrior). The 160-QFP package requires careful PCB layout with adequate thermal relief; consider a copper pour under the package even though power dissipation is modest.

Applications typiques
MCF5206ECFT40 convient pour 6 applications: Industrial Automation Controllers, Embedded Networking Gateways, Building Automation Systems, Point-of-Sale Terminals, Legacy 68000 Software Migration, Embedded Data Acquisition Systems.
Industrial Automation Controllers
The MCF5206ECFT40's 40 MHz ColdFire V2 core and integrated DRAM controller suit industrial PLC and motion controller designs that require deterministic 32-bit performance. Its 8 KB on-chip SRAM buffers real-time control loops while external SDRAM holds ladder-logic programs and HMI data. The 8 dedicated I/O lines interface directly to optocouplers and 24V signal conditioning, and the dual UARTs handle RS-232/RS-485 field-bus connections to motor drives and sensors. ColdFire's 68k heritage means many legacy factory-automation codebases port with minimal rewrite.
Recommandé
Embedded Networking Gateways
The MCF5206ECFT40's ColdFire V2 core delivers the throughput needed for protocol-conversion applications such as Modbus-to-Ethernet or serial-to-TCP gateways. At 40 MHz, the device can sustain TCP/IP stack processing plus UART handling for multiple serial ports, while the integrated DRAM controller supports the buffer memory required for packet queuing. The 8 KB SRAM is sufficient for the TCP/IP control structures when external SDRAM is used for socket buffers. NXP's ColdFire TCP/IP Lite stack supports this part natively.
Recommandé
Building Automation Systems
Building automation controllers for HVAC and access control benefit from the MCF5206ECFT40's combination of 32-bit performance and rich peripheral integration. The dual UARTs connect to BACnet MS-TP or Modbus RTU field buses, while the system integration module manages interrupts from sensors and keypads. The 40 MHz ColdFire core executes scheduling and PID loops for zone control, and the ROMless architecture lets each building controller use custom firmware. Industrial temperature rating supports unheated equipment closets.
Recommandé
Point-of-Sale Terminals
Legacy POS terminals and kiosk controllers use the MCF5206ECFT40 to drive LCD displays, scan barcodes, and process payment peripherals. The ColdFire V2 core runs transaction-handling code while the dual UARTs interface with PIN pads and receipt printers. The integrated DRAM controller simplifies PCB layout by removing the need for an external memory controller IC. With 8 KB SRAM and external SDRAM, the device can buffer transaction logs and cryptographic operations. The 160-QFP package suits through-hole-compatible manufacturing lines.
Recommandé
Legacy 68000 Software Migration
Designs upgrading from older Motorola 68000 and 68EC000 microprocessors use the MCF5206ECFT40 as a binary-compatible step because ColdFire V2 executes most 68k instructions natively. The 160-QFP footprint and bus architecture match legacy designs, minimizing PCB rework. Code compiled for 68k targets typically runs 2-3x faster at the same clock rate due to ColdFire's optimized instruction pipeline. This makes the part a popular choice for sustaining industrial equipment originally shipped in the 1990s.
Recommandé
Embedded Data Acquisition Systems
The MCF5206ECFT40 controls multi-channel data acquisition systems where 32-bit performance handles real-time DSP-like processing of ADC samples while the integrated DRAM controller buffers large datasets. The dual UARTs stream data to host PCs, and the 8 KB SRAM supports interrupt-driven sample scheduling. Industrial temperature operation allows deployment in factory-floor environments. ColdFire's deterministic interrupt latency is well-suited to time-critical acquisition tasks.

Principaux différenciateurs
- 40 MHz base speed with 54/60 MHz upgrade paths in same package (vs MCF5206ECFT60)
- 8 KB SRAM baseline with 16 KB upgrade option (vs MCF5207ECFT40)
- ColdFire V2 ISA preserves 68k binary compatibility (vs ARM Cortex-M3 MCU (STM32))
Notes de conception
The MCF5206ECFT40 dissipates approximately 1.5W typical at 40 MHz with all peripherals active in the 160-BQFP package. Estimated: at 5.0 V VCC and 300 mA active current, power = 5 V * 0.3 A = 1.5 W. With BQFP theta_JA around 35 C/W, junction temperature rise is 52 C above ambient - adequate headroom for industrial environments but no margin for sealed enclosures. Place a copper pour under the package and provide airflow for high-temperature operation.
The 160-BQFP package has 0.65 mm pitch gull-wing leads. Use a 4-layer PCB with dedicated ground and power planes to control impedance on the external memory bus. Keep bus trace lengths matched within 25 mm to avoid timing skew at 40 MHz. Place 0.1 uF decoupling capacitors near every VCC pin (pins 137-139) and bulk 10 uF tantalum capacitors on each supply island. The DRAM control signals (RAS/CAS/WE) require series 33 ohm termination resistors to dampen reflections.
Estimated: Do not skip the external clock source - the MCF5206ECFT40 requires a stable 40 MHz oscillator with 60/40 duty cycle percent on CLKIN (pin 82). Cold start: hold RESET asserted for at least 100 ms after VCC reaches 4.75 V to ensure proper PLL lock. Watchdog: configure the COP watchdog timer in software within the first 100 ms of boot or it will reset the part. JTAG: do not float TMS (pin 147) and TRST (pin 151) - pull TMS high through 10 kohm and assert TRST at power-up.
Informations de conformité
Compliance status for MCF5206ECFT40 not confirmed in verified web data. The MCF5206E family dates from the late 1990s - early production was leaded, later production may be lead-free. Confirm RoHS/REACH status with distributor at order time. Part is not AEC-Q100 qualified (industrial/consumer use only).
