Product details
Overview
MCF5307FT66B from Freescale Semiconductor is a ColdFire® v2 32-bit microprocessor with integrated DRAM controller, UARTs, I²C, timers, and DMA-designed for embedded networking and industrial control. It operates at 66 MHz CPU clock (PCLK), features 8 KB unified cache, 4 KB on-chip SRAM, and supports external 16-bit parallel bus interfacing.
For engineers reviewing the MCF5307FT66B datasheet, MCF5307FT66B pinout, MCF5307FT66B application, or MCF5307FT66B equivalent, key selection criteria include its ColdFire v2 core compatibility, PLL-configurable clocking, integrated SIM peripherals, and support for synchronous/asynchronous DRAM-critical for legacy industrial gateway and protocol-converter designs requiring long-lifecycle silicon.
Technical Context
The MCF5307FT66B implements the ColdFire v2 instruction set architecture with a dual-pipeline execution unit (IFP/OEP), hardware MAC, and integer divide module. Its System Integration Module (SIM) integrates PLL clock generation, interrupt controller, chip-select logic, and JTAG debug interface.
It supports external memory via a 16-bit data bus and 24-bit address bus, with configurable wait-state timing and programmable chip-select ranges. The integrated DRAM controller handles both synchronous and asynchronous DRAM, while dual UARTs and I²C enable serial communication in resource-constrained edge nodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF5307FT80B | Same ColdFire v2 core and peripheral set, but rated for 80 MHz PCLK-requires higher-grade crystal and tighter power supply regulation. | Supports higher throughput in packet-forwarding or encryption tasks where 66 MHz is insufficient. | Select only if application demands >66 MHz sustained CPU performance and thermal/power budget allows. |
| MCF5272CVM66 | Successor ColdFire v3 device with enhanced cache, USB 1.1, and lower power-different pinout and memory map; not pin-compatible. | Targets new designs requiring USB host capability or extended lifecycle beyond MCF5307 end-of-life. | Use for greenfield designs; avoid for drop-in replacement due to incompatible package and register layout. |
Compared with MCF5307FT66B, the MCF5307FT80B offers higher clock headroom within identical architecture and footprint, while the MCF5272CVM66 provides architectural upgrades at the cost of redesign effort-making MCF5307FT66B optimal for sustaining legacy industrial deployments with strict form-fit-function requirements.

FAQ
What is the maximum operating frequency of the MCF5307FT66B?
The MCF5307FT66B is factory-specified for a maximum CPU clock (PCLK) of 66 MHz, achieved via its internal PLL multiplying an external crystal input-typically 16.5 MHz. This frequency is guaranteed across the full industrial temperature range (–40°C to +85°C) and specified supply voltage (3.3 V ± 0.3 V). Exceeding this rating may result in timing violations or undefined behavior in the MCF5307FT66B.
Does the MCF5307FT66B include on-chip memory?
Yes, the MCF5307FT66B integrates 4 KB of on-chip SRAM mapped at fixed address 0x00000000 and an 8 KB unified instruction/data cache. The SRAM is directly accessible without wait states and commonly used for boot code, stack, or critical data buffers. The cache operates in write-through or copyback mode and is managed via dedicated CACR and ACR registers in the MCF5307FT66B.
Which communication interfaces are built into the MCF5307FT66B?
The MCF5307FT66B includes two UART modules (UART0 and UART1), one I²C module, a 16-bit parallel port for general-purpose I/O, and a JTAG interface for debug and programming. It does not include USB, CAN, or Ethernet MAC-those require external PHY or controller ICs. All serial interfaces are fully register-programmable and supported by the MCF5307FT66B's interrupt controller and DMA channels.
Is the MCF5307FT66B pin-compatible with other ColdFire processors?
No, the MCF5307FT66B is not pin-compatible with other ColdFire families such as MCF52xx or MCF54xx. It shares the same 256-pin PQFP package and core architecture with the MCF5307FT80B variant, but differs from MCF5272 or MCF5407 in pin assignment, power sequencing, and peripheral mapping-even though software may be partially portable. Always verify pinout against the MCF5307FT66B datasheet before board reuse.
What debug capabilities does the MCF5307FT66B support?
The MCF5307FT66B supports IEEE 1149.1 JTAG boundary-scan testing and full Background Debug Mode (BDM) via a dedicated 6-pin header interface. BDM enables real-time register inspection, memory read/write, breakpoint insertion, and program flow control without halting peripheral operation-essential for validating time-critical firmware on the MCF5307FT66B in production test and field diagnostics.
