NXP Semiconductors MCF5407CAI220

Overview

MCF5407CAI220 from NXP Semiconductors (originally Motorola) is a ColdFire® v2 32-bit microprocessor with integrated DRAM controller, dual UARTs, I²C module, and hardware MAC unit, operating at 220 MHz CPU frequency, featuring 16 KB instruction cache and 8 KB data cache, used in industrial networking gateways requiring deterministic real-time processing.

For engineers reviewing the MCF5407CAI220 datasheet, MCF5407CAI220 pinout, MCF5407CAI220 application, or MCF5407CAI220 equivalent, key selection considerations include PLL-configurable clock synthesis, on-chip SRAM base address register mapping, IEEE 1149.1 JTAG debug support, and synchronous/asynchronous DRAM interface timing compliance.

Technical Context

The MCF5407CAI220 implements a Harvard-architecture ColdFire v2 core with dual-pipeline execution (IFP/OEP), hardware integer divide, and 32×16-bit MAC unit supporting single-cycle multiply-accumulate operations. It integrates a System Integration Module (SIM) with programmable PLL, software watchdog timer, and pin assignment control.

Peripheral integration includes an I²C module compliant with Philips I²C specification, interrupt controller with 64 vector entries, chip-select logic for up to 16 memory regions, and DMA controller supporting scatter-gather transfers. The processor supports external bus operation at up to 110 MHz with configurable wait-state generation.

FAQ

What is the maximum supported DRAM capacity for the MCF5407CAI220?

The MCF5407CAI220 supports up to 16M×16-bit (32 MB) DRAM configurations via its synchronous/asynchronous DRAM controller. This is achieved using four bank-select lines and programmable row/column address multiplexing. The controller supports CAS-before-RAS refresh and auto-precharge, enabling reliable operation with standard JEDEC-compliant SDRAM parts. Designers must configure the DRAM timing registers (SDRAMCR, SDRAMRTR) per selected memory part datasheet.

Does the MCF5407CAI220 support JTAG boundary-scan testing?

Yes, the MCF5407CAI220 implements a full IEEE 1149.1-compliant Test Access Port (TAP) controller with dedicated TCK, TMS, TDI, TDO, and TRST pins. Boundary-scan testing is supported for interconnect verification across the 256-pin CPGA package. The TAP controller also enables real-time debug via Background Debug Mode (BDM), allowing non-intrusive memory/register inspection without halting the MCF5407CAI220 core.

Can the MCF5407CAI220 operate without external DRAM?

Yes, the MCF5407CAI220 can operate in standalone mode using only its on-chip 2 KB SRAM and internal caches. Boot code may be executed from internal SRAM or external flash mapped via chip-select CS0. The processor does not require external DRAM for basic functionality - it is optional for applications needing larger working memory. Cache coherency protocols ensure correct operation when mixing internal SRAM and external memory accesses.

What clock sources are supported by the MCF5407CAI220 PLL?

The MCF5407CAI220 PLL accepts a single-ended external clock input (CLKIN) ranging from 4 MHz to 50 MHz. It does not support differential crystal inputs or internal RC oscillators. The PLLCR register allows configuration of multiplication factors from 4× to 10×, generating PCLK up to 220 MHz. External clock stability and jitter must meet Motorola's specification: ±50 ppm frequency tolerance and < 100 ps peak-to-peak jitter for reliable MCF5407CAI220 operation.

Is the MCF5407CAI220 pin-compatible with other ColdFire processors?

No, the MCF5407CAI220 is not pin-compatible with other ColdFire families such as MCF52xx or MCF54xx derivatives beyond its own variant group (e.g., MCF5407CAI166). Its 256-pin CPGA package, signal assignments (e.g., PSTDDATA[7:0], DSACKn), and power sequencing requirements are unique to the MCF5407 series. Migration to newer ColdFire parts like MCF547x requires PCB redesign due to different package types (PBGA), voltage domains, and peripheral pin muxing.
