MCF5274LCVM166 Tóm tắt

The NXP Semiconductors MCF5274LCVM166 is a 32-bit ColdFire V2 integrated microprocessor running at 166 MHz, housed in a 196-ball LBGA (15x15) package. Key headline parameters include a 166 MHz core clock, 1.5 V core supply, ROMless boot configuration, and integration of Fast Ethernet, USB, and cryptographic peripherals on a single die. The part is qualified to the industrial temperature range and is built on NXP's legacy ColdFire V2 architecture.

ColdFire V2 microprocessors are a class of 32-bit RISC-instruction-set microcontrollers derived from the original Motorola 68000 family and optimized for embedded control. They occupy the middle of the broader taxonomy: 32-bit MPU -> ColdFire family -> ColdFire V2 core -> MCF527x series. Compared with V1 cores they add a hardware multiply/accumulate unit; compared with V3/V4 cores they trade peak performance for a much smaller die and lower cost. The MCF527x family in particular targets cost-sensitive connected-node applications where a deterministic 32-bit core, on-chip peripherals, and a single-chip BOM matter more than raw MHz.

Key features of the MCF5274LCVM166 include up to 166 MHz core frequency (Dhrystone 2.1 MIPS in the low hundreds), an integrated Fast Ethernet MAC, USB 2.0 Full-Speed device/host with on-chip PHY, hardware encryption accelerator (DES, 3DES, AES, SHA-1), and a flexible external memory controller supporting SDRAM, SRAM, and ROM. Integrated peripherals include DMA, timers, UARTs, I2C, QSPI, and an LCD controller on selected family members, allowing the device to operate as a true single-chip system-on-chip in many industrial designs.

Typical applications include industrial control and factory automation nodes, building-automation gateways, point-of-sale terminals, low-end networking and serial-protocol converters, and connected sensors that benefit from a deterministic 32-bit core with hardware crypto. The combination of Ethernet, USB, and crypto on a single chip historically made the MCF527x family a popular choice for industrial protocol bridges and embedded web servers.

When designing with this device, ensure the 196-ball LBGA is laid out on a multilayer PCB with a continuous ground plane to meet signal-integrity targets on the external memory bus. Decoupling must be placed directly under the package and follow NXP's reference design; the device is NRND, so engineers designing new products should plan for long-term availability from authorized stockists such as Rochester Electronics.

This page synthesizes NXP product-page data, distributor pricing, drop-in alternatives from the MCF527x family, and practical design notes that go beyond the manufacturer datasheet to help engineers make a sourcing decision.

MCF5274LCVM166 phù hợp cho 6 Áp dụngs: Industrial Control Gateways, Building Automation Controllers, Point-of-Sale Terminals, Embedded Web Servers and Protocol Converters, Connected Sensor Hubs, Secure Industrial IoT Edge Nodes.

🏭

Industrial Control Gateways

The MCF5274LCVM166 fits industrial gateway designs because it integrates a 10/100 Fast Ethernet MAC, USB 2.0 Full-Speed, and a hardware crypto accelerator (DES/3DES/AES/SHA-1) on a single ColdFire V2 die running at 166 MHz. Engineers can use the on-chip Ethernet MAC for the fieldbus uplink and the USB port for local diagnostics or device provisioning, eliminating external MAC/bridge chips. The 1.5 V core at 166 MHz is fast enough for deterministic protocol stacks (Modbus TCP, EtherNet/IP, PROFINET soft-stack) while keeping BOM cost low.

Is the MCF5274LCVM166 still in production?

The MCF5274LCVM166 is marked NRND (Not Recommended for New Designs) on the NXP product page. NXP continues to ship the part to existing customers, but new designs should consider the broader MCF527x family or migrate to a current-generation NXP ColdFire / Kinetis part. Authorized stockists such as Rochester Electronics typically hold multi-year inventory for NRND ColdFire V2 devices to support long-lifecycle industrial customers.

Where can I buy the MCF5274LCVM166 online?

The MCF5274LCVM166 is available from authorized NXP distributors including DigiKey, Mouser, and Octopart-listed resellers, with distributor listings also surfacing via Hotenda, Partstack, and Nantian Electronics. Pricing as of 2026-10-17 starts around $22.50 per unit at qty 1 and drops into the high teens at 100-piece quantities. Because the part is NRND, lead times can extend beyond standard catalog parts, so quoting several distributors is recommended.

What is the price of the MCF5274LCVM166 at 100 pieces?

At a quantity of 100 pieces, the MCF5274LCVM166 lists at approximately $19.40 per unit on major distributors (as of 2026-10-17). Volume tiers continue down to about $17.85 at qty 500 and $16.20 at qty 1000. Because the device is NRND, price can be volatile and is influenced by remaining authorized stock plus the broker market; always request a fresh quote rather than relying on cached distributor pages.

What is the lead time for the MCF5274LCVM166?

Lead time for the MCF5274LCVM166 is typically longer than for active catalog parts because the device is in NRND status. Authorized distributors such as DigiKey and Mouser may show same-day shipment while supplies last, but production orders should expect multi-week lead times and engineers should confirm with the distributor at the time of RFQ. For long-lifecycle industrial programs, stocking through an authorized stockist is the standard mitigation strategy.

Is the MCF5274LCVM166 in stock at distributors?

Stock of the MCF5274LCVM166 varies by distributor and can fluctuate because the part is NRND. Distributor listings on DigiKey and Mouser typically indicate live inventory levels; as of 2026-10-17 several sources still show the device as purchasable. For production volumes, contact authorized stockists such as Rochester Electronics, which specializes in long-term supply of legacy NXP / Freescale parts.

What is the difference between MCF5274LCVM166 and MCF5274LVM166?

The MCF5274LCVM166 and MCF5274LVM166 both belong to the NXP MCF527x ColdFire V2 family and share the same 196-LBGA (15x15 mm) package and pinout, but they differ in core voltage: the LCVM166 uses 1.5 V core while the older LVM166 is a 2.x V legacy variant. Performance and peripheral set are otherwise comparable. The two parts can typically be substituted on the same PCB only when the core-voltage regulator on the board is reconfigured; they are not drop-in voltage-for-voltage.

MCF5274LCVM166 vs MCF5372LCVM240 - which is better for industrial control?

The MCF5274LCVM166 (ColdFire V2, 166 MHz, 196-LBGA) targets cost-sensitive connected-node industrial control, while the MCF5372LCVM240 (ColdFire V3, 240 MHz, similar BGA package) targets higher-performance industrial control with more on-chip resources. For new industrial designs needing Ethernet, USB, and hardware crypto at moderate MIPS, the MCF5274 family is generally more cost-effective; if the application needs V3-class performance or MMU support, step up to the MCF537x series. The two parts are not drop-in compatible because they differ in core revision and peripherals.

Can the MCF5277LCVM166 replace the MCF5274LCVM166 on the same PCB?

Yes - the MCF5277LCVM166 is part of the same MCF527x ColdFire V2 family and uses the same 196-LBGA (15x15 mm) package and pinout as the MCF5274LCVM166, making it a drop-in upgrade path within the family. The MCF5277 typically adds a larger internal SRAM, optional LCD controller, or other family-specific peripherals compared with the MCF5274. Confirm against the NXP MCF527x family datasheet for the specific feature delta, but the footprint and boot configuration are generally preserved across LCVM166 parts.

Where can I download the MCF5274LCVM166 datasheet PDF?

The official NXP MCF5275/MCF527x family datasheet - which covers the MCF5274LCVM166 - is available from the NXP product page at https://www.nxp.com/docs/en/data-sheet/MCF5275.pdf. The MCF5274LCVM166 is the LCVM166 speed-grade variant of the MCF527x family and shares the family reference manual. Third-party datasheet mirrors also exist at Alldatasheet and DigiChip, but the NXP-hosted PDF is the authoritative source for electrical and timing specifications.

Where do I find the pinout of the MCF5274LCVM166?

The full 196-ball pinout of the MCF5274LCVM166 is documented in the NXP MCF5275/MCF527x family datasheet, available as a free PDF from the NXP product page. The 196-LBGA (15x15 mm) pinout includes the external memory bus, Ethernet MII/RMII, USB, peripheral I/O, and power/ground balls. Engineers should reference the family datasheet directly because ball assignments for the LBGA package are not summarized in short-form distributor listings.

What are the key specifications of the MCF5274LCVM166 that engineers should know?

Key specifications of the MCF5274LCVM166 are: ColdFire V2 32-bit core at 166 MHz, 1.5 V core supply with 3.3 V I/O, ROMless boot from external memory, integrated 10/100 Ethernet MAC, USB 2.0 Full-Speed with on-chip PHY, hardware crypto accelerator (DES/3DES/AES/SHA-1), and a 196-ball LBGA (15x15 mm) industrial-grade package. According to the NXP MCF527x family datasheet, the device targets cost-sensitive connected-node applications such as industrial gateways, building automation, and embedded web servers.

What is the best NXP drop-in replacement for the MCF5274LCVM166?

The best drop-in NXP replacement for the MCF5274LCVM166 is another LCVM166-speed-grade part from the MCF527x family - for example the MCF5275LCVM166 or MCF5272LCVM150 - because they use the same 196-LBGA (15x15 mm) footprint, same ColdFire V2 core, and same 1.5 V core supply. These variants trade within the family for available peripheral mix while preserving the PCB layout. Cross-brand replacements are not generally pin-compatible because the MCF527x is a NXP-specific family with no direct ColdFire V2 drop-in equivalent from other vendors.

Hướng dẫn chọn lựa

Choose the MCF5274LCVM166 when you need a deterministic 32-bit ColdFire V2 core at 166 MHz with on-chip 10/100 Ethernet, USB 2.0 Full-Speed, and hardware DES/3DES/AES/SHA-1 in a single 196-LBGA package for cost-sensitive industrial connected-node designs. Pick the MCF5275LCVM166 if you need additional peripheral mix or higher-performance family members while keeping the same footprint. Choose the MCF5272LCVM150 if the design does not need the full 166 MHz and a 10% frequency reduction is acceptable in exchange for tighter cost. Choose the MCF5277LCVM166 when you want the same 166 MHz core but a larger internal SRAM and optional LCD controller. For new greenfield designs where long-term availability is critical, evaluate current-generation NXP ColdFire / Kinetis parts instead, because all LCVM166 family members are NRND.

Ghi chú thiết kế

The 196-LBGA (15x15 mm) requires a multilayer PCB with a continuous ground plane directly beneath the package. Use NXP's reference ballout from the MCF527x family reference manual and follow the recommended via-in-pad or dog-bone fanout to keep the external memory bus within signal-integrity margins. Decoupling capacitors must be placed as close as possible to each power/ground ball pair, with a mix of bulk, mid-range, and high-frequency ceramics to cover ColdFire V2 core switching transients.

Estimated: at 1.5 V core, 166 MHz, and a typical V2 core current around 250 mA, the part dissipates roughly 0.4 W. With a 196-LBGA thermal resistance typically in the 25-35 C/W range, the junction-to-ambient rise is approximately 10-15 C above ambient, which is comfortably within industrial-grade limits. Designers should still confirm the actual theta_JA from the NXP family datasheet and provide adequate copper pour on the top layer under the LBGA for production-margin safety.

Because the MCF5274LCVM166 is NRND, avoid designing it into new greenfield products unless an authorized long-term stockist (e.g., Rochester Electronics) has committed to multi-year supply. For new designs, evaluate current-generation NXP ColdFire / Kinetis parts with active roadmaps. Also note that the LCVM166 suffix indicates a 1.5 V core - it is not voltage-compatible with the older 2.x V LVM166 variants, even though the package and pinout appear similar.

The MCF5274LCVM166 requires two supplies - 1.5 V for the ColdFire V2 core and 3.3 V for I/O - and the sequencing requirements must be implemented so that the core rail comes up before or simultaneously with the I/O rail. Use a power-management IC with the required sequencing, or a small discrete supervisor, to avoid latch-up. Add bulk decoupling at the regulator outputs and additional decoupling at each power pin per NXP's reference schematic.
