MCF5407AI162 - ColdFire V4 162MHz MPU 208-FQFP | NXP

The NXP MCF5407AI162 is a 32-bit ColdFire V4 microprocessor delivering up to 162 MHz core clock, with a ROMless architecture and 4 KB of internal SRAM, housed in a 208-pin FQFP (28x28 mm) package. It is the original member of the MCF540x family, the first standard microprocessor to implement the ColdFire V4 core and offers up to 316 MIPS (Dhrystone 2.1) of integer performance at full clock. The variable-length RISC technology combined with an enhanced ColdFire instruction set gives designers a high-performance control-plane processor with a slower, easier-to-route external system bus interface. A microprocessor (MPU) is a single-chip CPU that integrates the integer core, cache, bus controllers and peripheral bridges into one device, requiring external program memory (ROM/RAM) and I/O. ColdFire V4 sits in the Freescale/NXP MPU hierarchy between the ColdFire V2/V3 controllers and the higher-end PowerPC cores, offering RISC-like code density with deterministic interrupt latency. The MCF5407AI162 was specifically designed to ease migration for systems previously built around 68k/ColdFire parts that needed more headroom without moving to PowerPC toolchains. Key features include a 162 MHz internal core clock (selectable via clock divider relative to the system bus), 4 KB unified instruction/data SRAM, dual on-chip UARTs, a 10/100 Ethernet MAC, DMA, timers, and a 32-bit system bus with programmable Chip Select / SDRAM controllers. The integrated FPU is optional via the MCF5407 (no FPU) variant; the AI162 suffix designates the 162 MHz speed grade in the industrial -40C to +85C range. ROMless boot allows external Flash to host the firmware image and supports secure boot through external encryption devices. Typical applications include industrial control PLCs, networked embedded gateways, point-of-sale terminals, factory automation controllers, and any 68k-ColdFire legacy migration that needs more compute than the V2/V3 families. The Ethernet MAC and UARTs make it a fit for serial- or IP-connected supervisory controllers. The wide peripheral set (DMA, timers, CS, SDRAM) keeps the external glue logic low. When designing with this part, carefully observe the SDRAM controller timing parameters and provide adequate decoupling on the 3.3V core/IO rails. Boot mode strapping must be valid at reset for the chosen Flash address; consult the ColdFire MCF5407 reference manual for chip-select timing and SDRAM configuration registers.

MCF5407AI220

MCF5407AI220 - ColdFire V4 MPU, 220 MHz, ROMless 208-FQFP | NXP

The NXP MCF5407AI220 is a ColdFire V4 core microprocessor delivering up to 316 MIPS (Dhrystone 2.1) at a 220 MHz core clock, integrated SRAM, and a ROMless external bus interface, all in a 208-pin FQFP (28x28 mm) package. A microprocessor (MPU) is an integrated processor that fetches, decodes, and executes instructions from external memory, forming the central compute element of an embedded system. Within the embedded hierarchy, an MPU sits above microcontrollers (MCU) in that it relies on external memory for code and data, and is used when higher performance or larger memory maps are required than an MCU can supply. Key features of the MCF5407AI220 include a 32-bit ColdFire V4 core with up to 220 MHz internal frequency, a separate system bus that allows lower-speed external memory interfacing, integrated 4 KB SRAM, and a 3.3 V I/O supply with a 1.5 V internal core voltage. The device also offers a flexible bus interface (32-bit external bus with chip-select logic), DMA controllers, timers, UARTs, and a 16-channel interrupt controller. Architecturally, the ColdFire V4 core uses a variable-length instruction set (ISA_B+) with hardware Multiply-Accumulate (MAC) and hardware divide, accelerating DSP-style operations compared to earlier ColdFire cores. The dual-clock architecture decouples the high-speed core from the external bus, simplifying mixed-speed memory subsystems. Typical applications include industrial automation controllers, factory-floor HMI/PLC modules, point-of-sale terminals, networked embedded gateways, and high-performance data acquisition platforms where ROMless boot from external Flash is acceptable. A practical design consideration is power: at 220 MHz the core draws roughly 1.0-1.2 W, so a copper pour and thermal vias under the exposed pad region of the FQFP are recommended. Designers should also confirm availability, as NXP has marked the MCF5407 family for discontinuance and recommends a replacement part via their PCN.

As the first standard MPU to implement the ColdFire V4 core, it delivers up to 316 Dhrystone MIPS while keeping an easy-to-use lower-speed system interface for legacy ColdFire designs. A microprocessor (MPU) is a CPU-centric integrated circuit that requires external memory and peripherals, sitting at the top of the embedded hierarchy: MPU > microcontroller > SoC > ASIC. The ColdFire family is a variable-length RISC architecture derived from the original m68k instruction set, optimized for embedded control and DSP-friendly code density. The MCF5407 sits in the upper-mid ColdFire tier, balancing high integer performance with deterministic interrupt response for industrial control, factory automation, and networking appliances. Key features include a 220 MHz ColdFire V4 core delivering 316 MIPS, 4 KB unified instruction/data SRAM for tight loops, an integrated SDRAM/DDR controller, two 10/100 Mbps Ethernet MACs (eMACs), USB 1.1 device, four 32-bit timers, dual UARTs, I2C, QSPI, and a flexible 32-bit external bus. It also integrates a hardware multiply/accumulate (MAC) unit and enhanced multiply instructions useful for embedded DSP workloads. Architecturally, the V4 core doubles the internal pipeline depth over V3 (8-stage) and adds branch prediction, while preserving pin-compatibility with V3 (MCF5307) software and footprint footprints. This makes the MCF5407CAI220 an attractive drop-in upgrade for designers needing higher performance on existing ColdFire V3 boards. Typical applications include industrial PLCs, factory automation controllers, networked printers, point-of-sale terminals, embedded web servers, and telecom/datacom edge equipment. The dual Ethernet MACs and USB 1.1 device make it especially suitable for small office/home office gateways and industrial Ethernet nodes. Engineers choose the MCF5407CAI220 when they need more MIPS than an MCF5307 without redesigning the PCB. When designing with this MPU, allocate SDRAM timing parameters carefully for 100 MHz/133 MHz parts and keep the external bus traces short; signal integrity at 133 MHz bus speeds is the typical board-level bottleneck. Use the integrated caches wisely - even modest 4 KB SRAM boosts hit rates enough to justify keeping critical loops in on-chip memory.

This places the MCF54452 in the class of highly integrated MPUs that combine processing and connectivity in a single device. Key features include the ColdFire V4 core with an MMU (memory management unit), which enables full-featured embedded Linux deployments; integrated 10/100 Ethernet MAC, USB on-the-go (USB OTG), and PCI controller, providing a rich connectivity set rarely found on ColdFire-class devices; and ROMless architecture for flexible code storage strategies. The V4 core implements enhanced Harvard architecture with separate instruction and data buses, supporting higher instruction throughput than earlier V3 cores. The on-chip MMU provides virtual memory management with hardware page translation, essential for running protected-mode operating systems. Integrated peripherals reduce external component count and total board cost. Typical applications include industrial embedded control systems, network-connected consumer devices, and gateways requiring Ethernet plus USB connectivity. The 266 MHz performance class suits protocol processing, data aggregation, and human-machine interface workloads. Design consideration: since the device is ROMless, boot code must reside in external NOR flash mapped into the core's address space; verify the BGA-360 footprint follows the manufacturer's recommended land pattern and thermal via design. This page synthesizes distributor availability data, drop-in family alternatives, and practical design notes not found in the manufacturer datasheet, with lifecycle status (End of Life per NXP) clearly flagged for sourcing teams.
