Manufacturer

Motorola Semiconductor (now part of NXP Semiconductors) pioneered the ColdFire architecture as a high-performance, low-power evolution of the 68K family for deeply embedded systems.

The MCF5407AI220 belongs to the ColdFire v2 microprocessor family, engineered for deterministic real-time control in resource-constrained industrial and communications equipment where code density, interrupt latency, and peripheral integration are critical.

FAQ

What is the operating temperature range for the MCF5407AI220?

The MCF5407AI220 is rated for industrial temperature operation from –40 °C to +85 °C. This range is validated per Motorola's electrical specifications and supports deployment in harsh environments such as factory floors, outdoor telecom cabinets, and vehicle-mounted control units. The 'I' suffix in the part number explicitly denotes industrial grade, and thermal design must account for the 256-pin PBGA package's junction-to-case resistance.

Does the MCF5407AI220 support external SDRAM?

Yes, the MCF5407AI220 includes a dedicated Synchronous DRAM controller capable of driving standard x16 or x32 SDRAM devices with programmable CAS latency, burst length, and refresh timing. Configuration is performed via the SIM's SDRAM Control Register (SDCR) and Mode Register Set (MRS) commands issued through the chip-select module. This eliminates the need for an external memory controller when building cost-sensitive systems.

How does the MCF5407AI220 handle interrupt latency?

The MCF5407AI220 achieves sub-1 µs worst-case interrupt response time due to its 64-vector interrupt controller, priority encoding, and pipeline-aware vector fetch. Latency is further reduced by the ability to lock critical ISR code in instruction cache and configure fast interrupt entry via the Autovector Register (AVR). This makes the MCF5407AI220 suitable for hard real-time tasks like PWM synchronization and encoder counting in motion control.

Can the MCF5407AI220 execute code directly from its on-chip SRAM?

Yes, the MCF5407AI220 supports zero-wait-state execution from its 2 KB internal SRAM when mapped into the linear address space via RAM Base Address Registers (RAMBAR0/RAMBAR1). This is commonly used for boot code, critical ISRs, or real-time buffers. Unlike cache, SRAM access is fully deterministic and unaffected by cache coherency protocols, making it ideal for time-critical routines in the MCF5407AI220 design.

Is JTAG debugging supported on the MCF5407AI220?

Yes, the MCF5407AI220 implements IEEE 1149.1 JTAG Test Access Port (TAP) with full boundary-scan support and integrated Background Debug Mode (BDM). The TDI/TDO/TCK/TMS pins enable standard JTAG tools to perform flash programming, register inspection, and real-time trace using the PSTDDATA[7:0] parallel debug bus - all without halting the MCF5407AI220 core during active operation.
