MCF5307CAI66B Ringkasan

The NXP Semiconductors MCF5307CAI66B is a 32-bit ColdFire V3 microprocessor running at 66 MHz (up to 70 MIPS), housed in a 208-pin FQFP (28x28 mm) tray package. It is a high-performance, cost-effective, highly integrated MPU designed for embedded control applications, combining a ColdFire V3 core with a multiply-accumulate (MAC) module, DRAM controller, DMA controller, timers, and parallel/serial interfaces.

A microprocessor (MPU) is an integrated circuit that contains the CPU, control unit, and on-chip peripherals in a single device. Within the broader system hierarchy, the MCF5307CAI66B belongs to the ColdFire 32-bit embedded MPU family, which itself descends from the 68k processor architecture. ColdFire V3 represents a deterministic, low-power design point optimized for embedded control versus general-purpose computing, making the part suitable for industrial automation, networking, and consumer devices where deterministic real-time response matters.

Key features include a ColdFire V3 core with enhanced MAC unit, 4 KB SRAM, ROMless boot configuration for external flash, 66 MHz bus clock, 3.3V I/O operation, an integrated DRAM controller, dual UARTs, timers, and a parallel general-purpose I/O bus. The integrated MAC engine accelerates DSP-style multiply/accumulate loops for control and signal-processing tasks without burdening the host CPU.

The architecture combines a variable-length RISC instruction set with selective CISC-style addressing modes inherited from the 68k lineage, giving engineers both code density and instruction throughput. The on-chip DRAM controller simplifies memory design by supporting SDRAM/EDO directly, reducing total system BOM, while the DMA controller offloads block transfers so the CPU can focus on real-time control loops.

Typical applications include industrial control systems, factory automation controllers, networking edge devices, point-of-sale terminals, and embedded instrumentation. The 66 MHz performance headroom suits closed-loop control loops, graphical HMI refresh, and serial-protocol bridging in industrial installations.

Design considerations include 3.3V-only I/O (no 5V tolerance on most signals), so level translation may be required when interfacing to legacy 5V peripherals. Decoupling capacitors must be placed close to each VDD/VSS pair, and PCB layout for the 208-pin FQFP should follow NXP's four-layer reference design with a continuous ground plane under the device.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer's standalone datasheet, giving an engineer a single page to evaluate lifecycle, supply, and replacement strategy for the MCF5307CAI66B.

What is the operating temperature range of the MCF5307CAI66B?

The MCF5307CAI66B operates from -40C to +85C industrial temperature range. According to the NXP MCF5307 datasheet, this part is rated for industrial-grade embedded environments, not automotive. Engineers specifying outside this range should consider the MCF5307AI66B or confirm with NXP for any extended-temperature variants, since the ColdFire V3 silicon limits the thermal envelope.

Is the MCF5307CAI66B still in production or end-of-life?

The MCF5307CAI66B is in last-time-buy (LTB) status as of 2026-10-17 per NXP's product page. The ColdFire MCF5307 family has been progressively moved to LTB over recent years as NXP concentrates on newer ColdFire and Kinetis families. Engineers should plan for last orders now and design a migration path to MCF532x or Kinetis for new designs.

What is the difference between MCF5307CAI66B and MCF5307AI66B?

Both MCF5307CAI66B and MCF5307AI66B share the same ColdFire V3 66 MHz silicon core, the same 208-FQFP package, and the same integrated peripherals. The C suffix vs A suffix typically denotes a slight silicon revision or qualification lot identifier. Functionally they are drop-in compatible; the engineer should confirm pinout and errata equivalence against the latest NXP revision document before substituting in production.

What package does the MCF5307CAI66B use?

The MCF5307CAI66B uses a 208-pin FQFP (Fine-pitch Quad Flat Pack) measuring 28x28 mm, supplied in tray packaging per NXP's tray standard. The 208-FQFP footprint is shared across the MCF5307 family, allowing PCB reuse among variants such as MCF5307AI66B and MCF5307CAI66B. Reference designs from NXP use a four-layer PCB with continuous ground plane under the device for thermal and signal-integrity reasons.

Where to download the MCF5307CAI66B datasheet PDF?

The MCF5307CAI66B datasheet PDF is available directly from NXP at https://www.nxp.com/docs/en/data-sheet/MCF5307.pdf, which is the authoritative source. Third-party mirrors such as DigiKey's product page (https://www.digikey.com/en/products/detail/nxp-usa-inc/MCF5307CAI66B/954797) also link to the same document. Always prefer the NXP-hosted PDF to ensure the latest revision and errata are referenced.

Where to buy MCF5307CAI66B online and what is the price?

The MCF5307CAI66B is available from authorized distributors including DigiKey, Mouser, Arrow, and LCSC, with LCSC listing the part from $38.88 as of 2026-10-17. Heisener and Octopart also surface stock from independent distributors. Because the part is in last-time-buy status, pricing can fluctuate as authorized stock depletes - request quotes from at least two authorized sources before committing to volume orders.

What is the lead time for MCF5307CAI66B orders?

Lead time for the MCF5307CAI66B varies by distributor: Heisener advertises immediate shipment for in-stock units (estimated delivery Jul 25 - Jul 30 within their listing), while broader distributor availability should be checked live. As of 2026-10-17, last-time-buy status means new manufacturing has ended, so lead time is dictated by remaining authorized-channel inventory and may lengthen sharply as stock depletes.

What is the best drop-in replacement for MCF5307CAI66B?

The closest drop-in replacement for the MCF5307CAI66B is the MCF5307AI66B - same ColdFire V3 66 MHz silicon, same 208-FQFP footprint, and same peripheral set. The C vs A suffix change reflects a minor silicon/mask revision but maintains pin-to-pin compatibility. Engineers should cross-check the NXP errata documents for any subtle differences in peripheral behavior before committing to a long production run.

MCF5307CAI66B vs MCF5272VM66 - which is better for industrial control?

The MCF5307CAI66B (ColdFire V3, 70 MIPS, 66 MHz, integrated MAC, integrated DRAM controller) is the stronger choice for industrial control versus the MCF5272VM66, which is a ColdFire V2 part at a similar clock but without the V3 MAC enhancements. The V3 core provides roughly 1.3x the integer performance and adds dedicated MAC instructions for control-loop DSP, while keeping the same 208-FQFP footprint family.

Is MCF5307CAI66B suitable for factory automation applications?

Yes, the MCF5307CAI66B is well suited for factory automation: 70 MIPS ColdFire V3 performance handles real-time control loops, the integrated MAC accelerates filter and PID computations, the integrated DRAM controller reduces BOM cost, and dual UARTs plus parallel GPIO support typical fieldbus and HMI integration. The industrial -40C to +85C temperature rating covers most factory-floor enclosures without additional ruggedization.

When should I choose MCF5307CAI66B over MCF532x or Kinetis?

Choose the MCF5307CAI66B when you are maintaining an installed base that already uses this exact part, when re-spinning an existing ColdFire V3 design, or when you have a short lifecycle product that will retire before stock depletes. Choose MCF532x for designs that need USB, Ethernet MAC, or longer lifecycle support; choose Kinetis for new designs requiring ARM Cortex-M, modern toolchains, and active longevity. New designs should not start on MCF5307CAI66B.

What are the key specifications of MCF5307CAI66B that engineers should know?

The MCF5307CAI66B delivers 70 MIPS from a ColdFire V3 core at 66 MHz, integrates 4 KB of on-chip SRAM, ships ROMless for external flash boot, runs at 3.3V, integrates a DRAM controller, DMA controller, two UARTs, timers, and parallel GPIO, and is packaged in a 208-FQFP (28x28 mm) on tray. It is rated -40C to +85C and is in last-time-buy status as of 2026-10-17, meaning new production has ceased.

What can replace the MCF5307CAI66B if stock is unavailable?

If authorized MCF5307CAI66B stock is depleted, the most direct replacement is the MCF5307AI66B (same family, same 208-FQFP, same peripherals). For longer lifecycle support consider the MCF5329CVM240, which is a newer ColdFire V3 family member in a similar MAPBGA package, or move to a Kinetis K60 part for ARM Cortex-M4 with significantly more performance and active longevity.

Is there a Kinetis equivalent for MCF5307CAI66B designs?

A reasonable Kinetis equivalent for MCF5307CAI66B designs is the Kinetis K60 family (for example MK60DN512VLQ10), which provides an ARM Cortex-M4 core at up to 100 MHz, comparable integrated peripherals, and an active NXP longevity program. K60 parts are NOT pin-compatible with the 208-FQFP footprint of the MCF5307CAI66B, so a PCB redesign is required; the migration is software-portable via the Freescale/NXP Processor Expert toolchain.

Does the MCF5307CAI66B support SDRAM directly?

Yes, the MCF5307CAI66B integrates a DRAM controller that supports SDRAM, EDO DRAM, and page-mode DRAM directly without an external memory controller. According to the NXP MCF5307 datasheet, the integrated controller handles refresh and addressing, simplifying board design and reducing BOM. The DRAM interface is multiplexed onto the external bus pins, so PCB layout must follow NXP's reference design for signal integrity at 66 MHz.

Panduan Pemilihan

Choose the MCF5307CAI66B when you are maintaining or refreshing an existing ColdFire V3 design that uses the 208-FQFP footprint, when you need 70 MIPS of deterministic processing, and when the design lifecycle will end before authorized stock fully depletes. Choose the MCF5307AI66B as a drop-in alternate - same silicon, same package, possibly different qualification lot. Choose the MCF5329CVM240 if you need more performance and are willing to migrate to the higher clock rate within the same footprint family. Choose the Kinetis K60 family for new designs requiring active longevity and ARM Cortex-M4 processing; the migration requires PCB redesign. Avoid choosing the MCF5272VM66 - it is obsolete, uses a different package, and lacks the V3 MAC acceleration.

Diferensiator Kunci

ColdFire V3 core with integrated MAC unit (vsMCF5272VM66)
Larger 208-FQFP package footprint with 23-bit address bus (vsMCF5272VM66 (196-MAPBGA))
Higher clock speed headroom on the same footprint family (vsMCF5329CVM240)

Catatan Desain

The MCF5307CAI66B requires a clean 3.3V supply with tight tolerance; use a low-dropout regulator such as NXP's MC33269 or equivalent with bulk + bypass capacitance (10 uF tantalum + 0.1 uF ceramic per VDD pin). Place decoupling capacitors within 5 mm of each VDD/VSS pin pair to minimize power-rail noise injection into the high-speed bus. Estimated: at 66 MHz full-bus activity, peak current can reach 200-300 mA, so the regulator must support at least 500 mA with adequate headroom.

The 208-FQFP 0.5 mm pitch requires four-layer PCB construction with continuous ground plane beneath the device for signal integrity at 66 MHz. Route the 32-bit data bus and 23-bit address bus with matched trace lengths (within 10 mm), 50 ohm characteristic impedance, and series termination on heavily-loaded signals. Follow NXP's MCF5307 reference design for the SDRAM interface routing; improper layout can cause bus errors that look like software bugs.

Do not assume the MCF5307CAI66B is 5V tolerant - all I/O is 3.3V only. Connecting a 5V peripheral directly will damage the part. Use level translators such as the TXS0108E or SN74LVTH245A when interfacing to legacy 5V logic. Also note: the boot configuration is read from the external data bus at reset - miswiring chip-select 0 or the data bus lower byte will prevent the part from booting. Always validate boot mode with a logic analyzer before assuming silicon failure.
