MCF5407AI220 - ColdFire V4 MPU, 220 MHz, ROMless 208-FQFP | NXP
料号： MCF5407AI220 ✗ 停产MCF5407AI220 概述
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.

典型应用
MCF5407AI220 适用于 6 应用s: Industrial Automation Controller, Point-of-Sale (POS) Terminal, Embedded Networked Gateway, High-Performance Data Acquisition Platform, Factory-Floor HMI / Operator Panel, Legacy Replacement for M68K Embedded Boards.
Industrial Automation Controller
The MCF5407AI220's 220 MHz ColdFire V4 with hardware MAC/divide makes it well suited to industrial PLC and motion-control loops running PID algorithms at high update rates. Its 32-bit external bus and 4 chip-select lines directly address 16- or 32-bit external Flash plus SDRAM, allowing deterministic boot and runtime memory mapping typical of factory-floor controllers. The industrial temperature range (-40C to +85C) of the 'AI' suffix variant supports cabinets and outdoor enclosures. Power dissipation of ~1.0-1.2 W at 1.5 V core is manageable with a modest copper pour under the FQFP exposed pad. Recommended companions include external 16 MB NOR, 32 MB SDRAM, and an RS-485 transceiver on the UART lines.
推荐
Point-of-Sale (POS) Terminal
POS terminals require moderate CPU performance for transaction processing, cryptography, and display rendering, all of which the MCF5407AI220's 316 MIPS Dhrystone throughput delivers. The ColdFire V4 core's hardware MAC speeds up SHA/CRC operations commonly used in payment pipelines. The ROMless external bus interface supports booting a signed firmware image from external NOR Flash, an important security posture for payment devices. The 208-FQFP package fits comfortably on the larger mainboards typical of countertop POS hardware where BGA mounting is undesirable. Designers can pair the MPU with a touchscreen controller and thermal printer interface on its DMA-capable peripherals.
推荐
Embedded Networked Gateway
The MCF5407AI220 is well matched to industrial gateway designs that aggregate fieldbus (Modbus, Profibus, CAN) traffic and bridge it to Ethernet or cellular uplinks. Four UARTs, two DMA channels, and a 32-bit external bus simplify interfacing to multiple serial peripherals without external glue logic. The 220 MHz core comfortably handles IP packet forwarding, TLS handshakes, and protocol translation stacks. ColdFire's mature toolchain (gcc, CodeWarrior, and Lauterbach TRACE32 support) shortens firmware development for these stacks. The exposed-pad 208-FQFP allows straightforward PCB thermal management in enclosed gateway housings.
推荐
High-Performance Data Acquisition Platform
For data acquisition systems digitizing multiple analog channels at high sample rates, the MCF5407AI220's ColdFire V4 MAC engine accelerates on-the-fly DSP operations like FIR filtering and FFT preprocessing before storage. The 32-bit external bus streams data from parallel-output ADCs at full conversion rates without bottlenecks, while the DMA engine offloads block transfers from the core. Industrial-grade 'AI' temperature rating allows deployment in factory test cells and outdoor instrumentation cabinets. The 208-FQFP's generous pin count supports many concurrent peripheral interfaces, useful when scaling channel count.
推荐
Factory-Floor HMI / Operator Panel
Operator panels driving 800x480 or 1024x768 TFT displays require enough MIPS for graphics rendering, touch input handling, and protocol stacks (Modbus, EtherNet/IP). The MCF5407AI220's 316 MIPS supports lightweight graphics libraries without external GPU silicon, and the 32-bit external bus connects directly to TFT controllers in 16-bit or 24-bit modes. The industrial temperature rating (-40C to +85C) handles the warm switchgear cabinet environment typical of factory floors. The exposed-pad 208-FQFP enables solid thermal contact with the operator panel's metal backplate. Designers typically pair this MPU with a TFT controller and external SDRAM framebuffer.
推荐
Legacy Replacement for M68K Embedded Boards
The MCF5407AI220 is commonly used as a drop-in upgrade for designers moving from older 68000/68040 designs to ColdFire without rewriting every peripheral register access. ColdFire's source-level compatibility with M68K assembly and similar memory model let legacy firmware migrate with modest effort. The 208-FQFP package pinout differs from older 68040 PQFP packages, but many adapter PCBs exist for board-level retrofits. The 220 MHz ColdFire delivers substantially more MIPS than legacy 25-40 MHz M68K parts while keeping power budgets in check. This makes it a popular bridge part for defense and industrial systems with long lifecycles.

设计说明
The MCF5407AI220 requires two supplies: 1.5 V for the internal Vcore (driving the ColdFire V4 core at 220 MHz) and 3.3 V for I/O and analog. Core current at 220 MHz is roughly 700-800 mA (approximately 1.0-1.2 W). Provide a low-ESR 1.5 V regulator with at least 1.5 A headroom, and place 10 uF ceramic + 100 nF decoupling on each Vcore pin. Power sequencing: bring 3.3 V up first, then 1.5 V; sequence-out faults can cause latch-up on the core logic.
At 220 MHz the device dissipates approximately 1.0-1.2 W in the 208-FQFP (28x28 mm). With a typical theta_JA of ~25 C/W for a 4-layer JEDEC board, junction temperature rises ~30C above ambient at full load. For sealed industrial enclosures with high ambient, add a copper pour under the package and thermal vias to the inner planes. The exposed die-pad region of the FQFP should be soldered to the pad for maximum heat extraction.
Because the MCF5407AI220 is EOL, do not redesign a new product around it without a documented long-term supply commitment from authorized distributors like Rochester Electronics. Verify date code, lot trace, and RoHS marking on every shipment - EOL parts are frequent targets for remarking. For new designs, follow NXP's PCN-recommended ColdFire or Kinetis replacement parts even though they require PCB rework; sourcing a long-term EOL part introduces supply-chain risk.
Route the 32-bit external data bus with matched-length traces (target +/-250 mil at 50 MHz bus speed) and a 33 ohm series-termination resistor network. Place external SDRAM as close to the data/address bus pins as possible to keep stub lengths under 500 mil. The 208-FQFP 0.5 mm pitch requires 4-mil trace/space design rules; use blind/buried vias if routing density is constrained. Keep PLL supply pins (VDDPLL) filtered with a ferrite bead and 10 nF cap to reduce jitter.
