NXP Semiconductors MCF5407CFT162

Overview

MCF5407CFT162 from NXP Semiconductors (formerly Motorola) is a ColdFire® v2 32-bit microprocessor with integrated system-level peripherals, designed for embedded control and communications applications. It features a 162 MHz CPU clock (via PLL), 16 KB instruction cache + 8 KB data cache, on-chip 2 KB SRAM, and hardware MAC unit. Used in industrial gateways, protocol converters, and legacy telecom line cards requiring deterministic real-time processing.

For engineers reviewing the MCF5407CFT162 datasheet, MCF5407CFT162 pinout, MCF5407CFT162 application, or MCF5407CFT162 equivalent, key selection considerations include ColdFire v2 ISA compatibility, external bus interface timing, I²C/UART peripheral integration, PLL configuration flexibility, and BDM debug support for legacy firmware maintenance.

Technical Context

The MCF5407CFT162 implements the ColdFire v2 core with dual-pipeline architecture (IFP/OEP), Harvard memory organization, and hardware integer divide. Its System Integration Module (SIM) provides unified clock control, interrupt prioritization, chip-select mapping, and JTAG/BDM debug access.

Peripheral integration includes two UARTs, one I²C module, four 16-bit timers, DMA controller, DRAM/SRAM controller, and 16-bit parallel I/O port. All peripherals are memory-mapped and accessible via the 32-bit address/data multiplexed external bus interface operating at up to 81 MHz.

FAQ

What is the maximum operating frequency of the MCF5407CFT162?

The MCF5407CFT162 operates at a maximum CPU frequency of 162 MHz, achieved by configuring its on-chip PLL to multiply an external reference clock (typically 4–50 MHz). The PLL supports programmable dividers and multipliers, enabling precise clock synthesis for system synchronization. This frequency is specified under commercial temperature range (0°C to +70°C) with appropriate VDD and cooling conditions. The MCF5407CFT162 does not support overclocking beyond this rated speed.

Does the MCF5407CFT162 include on-chip flash memory?

No, the MCF5407CFT162 does not integrate flash memory. It relies on external nonvolatile storage (e.g., parallel NOR flash or EEPROM) connected via its chip-select interface for program code storage. The device includes 2 KB of on-chip SRAM for data and stack operations, and supports booting from external memory using configurable reset vector mapping. This architecture reflects its role as a microprocessor-not a microcontroller-and requires external memory design. The MCF5407CFT162 boot sequence is fully documented in Section 6.2.3 of the user's manual.

How is debug supported on the MCF5407CFT162?

The MCF5407CFT162 supports debugging via IEEE 1149.1 JTAG and Motorola's Background Debug Mode (BDM), using dedicated TCK/TMS/TDO/TDI pins plus a 2-wire serial BDM interface (BKPT and BDMCLK). BDM enables real-time memory inspection, register read/write, breakpoint setting, and single-stepping without halting peripheral operation. The MCF5407CFT162 implements full BDM command set compliance, including memory dump/fill and PC synchronization. Debug tools such as P&E Micro's ColdFire BDM interfaces are verified for use with the MCF5407CFT162.

Can the MCF5407CFT162 interface directly with DDR SDRAM?

No, the MCF5407CFT162 does not support DDR SDRAM. Its DRAM controller is designed exclusively for asynchronous SRAM, synchronous SRAM, and single-data-rate (SDR) SDRAM-specifically PC66/PC100/PC133-compliant chips with standard x16/x32 organization. DDR timing requirements (double-data-rate strobes, DLL calibration, impedance control) are not implemented. For DDR-capable ColdFire solutions, designers must migrate to later families like the MCF547x or consider external bridge ICs. The MCF5407CFT162 datasheet explicitly limits DRAM support to SDR configurations.

Is the MCF5407CFT162 pin-compatible with other ColdFire processors?

No, the MCF5407CFT162 is not pin-compatible with other ColdFire processors, including earlier MCF5200 series or later MCF547x devices. Its 256-pin LQFP package has unique signal assignments for the external bus interface, peripheral I/O, and debug pins. While functional similarities exist across the ColdFire family (e.g., UART/I²C register layout), mechanical and electrical pin mapping differs significantly. Migration to alternate ColdFire variants requires PCB redesign. The MCF5407CFT162 pinout is fully defined in Chapter 11 ("Mechanical Data") of the MCF5407UM/D user's manual.
