Product details
Overview
MCF5206EFT40 from Freescale Semiconductor is a Version 2 ColdFire® integrated microprocessor featuring a 54 MHz CPU core, 4 KB instruction cache, 8 KB on-chip SRAM, hardware multiply-accumulate (MAC) and divide units, and dual-channel DMA - deployed in industrial control systems requiring deterministic real-time response and legacy 68K software compatibility.
For engineers reviewing the MCF5206EFT40 datasheet, MCF5206EFT40 pinout, MCF5206EFT40 application, or MCF5206EFT40 equivalent, key selection considerations include its 208-pin PQFP package, 3.3 V core/5 V tolerant I/O, DRAM controller with EDO/page-mode support, dual UARTs, and I²C-compatible bus interface for embedded system integration.
Technical Context
The MCF5206EFT40 implements a fully static, synthesizable ColdFire V2 core with Harvard architecture: separate 4 KB direct-mapped instruction cache and 8 KB on-chip SRAM enable single-cycle code/data access. Its MAC and hardware divide units accelerate DSP-like arithmetic without external coprocessors.
Integrated peripherals include a DRAM controller supporting EDO and page-mode DRAMs, two 16-bit multimode timers, dual UARTs with synchronous/asynchronous operation, an I²C-compatible bus interface, JTAG debug support, and an 8-bit parallel I/O port - all accessible via glueless 8/16/32-bit memory-mapped interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Version 2 ColdFire® - synthesizable, Harvard-architecture core with 54 MHz max frequency and Dhrystone 2.1 performance of 50 MIPS. |
| On-Chip Memory | 4 KB instruction cache + 8 KB SRAM - enables zero-wait-state execution of critical firmware and data buffers. |
| DRAM Controller | Supports EDO and page-mode DRAMs - eliminates need for external DRAM logic in cost-sensitive embedded designs. |
| DMA Channels | 2 independent channels - offloads CPU for high-throughput peripheral-to-memory transfers (e.g., UART-to-SRAM streaming). |
| UART Interfaces | 2 Universal Synchronous/Asynchronous Receiver/Transmitters - provides native RS-232/RS-485 connectivity without external transceivers. |
| Operating Voltage | 3.3 V core supply with 5 V tolerant I/O pins - simplifies mixed-voltage board design and interfaces directly with legacy 5 V peripherals. |
| Temperature Range | 0°C to +70°C - qualified for commercial/industrial ambient environments without extended thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar embedded microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF5206EMF40 | Same core and peripherals, but in 160-pin QFP package - lacks DRAM controller and one UART. | Targeted at space-constrained designs where external memory is not required and lower I/O count suffices. | Select MCF5206EMF40 only if DRAM interface and second UART are unnecessary; otherwise MCF5206EFT40 provides full feature set. |
| MCF5208EC | Successor ColdFire V2 device with 80 MHz core, 16 KB SRAM, enhanced DMA, and integrated FEC Ethernet MAC. | Designed for networked embedded systems requiring TCP/IP stack offload and higher throughput than UART-only interfaces. | Choose MCF5208EC when Ethernet connectivity and >50 MIPS performance are mandatory; MCF5206EFT40 remains optimal for cost-sensitive UART/DRAM-based control. |
Compared with MCF5206EMF40, the MCF5206EFT40 adds DRAM control and dual UARTs in a larger 208-pin package; versus MCF5208EC, it trades Ethernet capability and higher clock speed for lower BOM cost and proven qualification in long-lifecycle industrial deployments.

FAQ
What is the maximum operating frequency of the MCF5206EFT40?
The MCF5206EFT40 operates at a maximum frequency of 54 MHz, delivering 50 Dhrystone 2.1 MIPS performance. It is also offered in a 40 MHz variant (MCF5206EFT40) for thermally constrained or lower-power applications. The core uses a fully static design, allowing clock throttling or stop modes without loss of state.
Does the MCF5206EFT40 support external DRAM, and what types are compatible?
Yes, the MCF5206EFT40 integrates a DRAM controller supporting EDO (Extended Data Out) and page-mode DRAMs. It provides full address/control signal generation for 8-, 16-, and 32-bit wide DRAM configurations. No external DRAM logic is required, enabling glueless expansion of program and data memory beyond the on-chip 8 KB SRAM.
Is the MCF5206EFT40 pin-compatible with earlier ColdFire microprocessors?
Yes, the MCF5206EFT40 uses a 208-pin PQFP package and is pin-compatible with the original MCF5206. This allows direct drop-in replacement in existing designs, delivering nearly three times the performance without PCB or schematic modifications - provided the target board supports the higher 54 MHz clock and updated power sequencing.
What debug interfaces does the MCF5206EFT40 provide?
The MCF5206EFT40 includes IEEE 1149.1 JTAG boundary-scan support for production testing and real-time in-circuit emulation. It also supports background debug mode (BDM) for non-intrusive breakpoint insertion, register inspection, and memory read/write during active execution - essential for validating time-critical embedded firmware.
Can legacy 68K assembly code be reused on the MCF5206EFT40?
Yes, Freescale provided free code translation utilities under license to convert MC683xx assembly into ColdFire-compatible object code. The MCF5206EFT40's ColdFire V2 core maintains binary compatibility for many common instructions, and its toolchain supports mixed-language development - enabling incremental migration of legacy 68K firmware onto the MCF5206EFT40 platform.
