SC543207CFUE8 Overview
The NXP Semiconductors (formerly Freescale Semiconductor) SC543207CFUE8 is a specialized interface/microcontroller-class integrated circuit delivered in a 176-pin LQFP (Low-profile Quad Flat Package). Originally released by Freescale Semiconductor and now commonly brokered through authorized inventory holders such as Rochester Electronics and LCSC Electronics, the SC543207CFUE8 falls into the broader category of "specialized ICs" and serves as a custom or application-specific silicon solution for embedded designs that require a non-standard part number with Freescale/NXP pedigree.
A specialized IC (also called an Application-Specific Standard Product or ASSP) is an integrated circuit designed for a particular function or a narrow set of applications rather than as a general-purpose device such as a microcontroller, op-amp, or LDO. Specialized ICs sit beneath the broader hierarchy of semiconductors -> integrated circuits -> logic/signal/interface ICs -> application-specific ICs. Because they are typically designed around a single end-application (e.g., a proprietary communication protocol, a custom motor-control loop, or a customer-defined bus interface), they are often sold under long, alphanumeric MPNs that encode internal project codes - exactly the case with the SC543207CFUE8 suffix, where SC54 often denotes a Freescale/NXP internal series identifier.
Key features of the SC543207CFUE8 include its 176-pin LQFP surface-mount package with a low-profile body (1.4 mm) suitable for automated assembly, industrial-grade operating temperature range typical of Freescale/NXP embedded silicon, and surface-mount construction designed for high-density PCB layouts. The part is offered in tape-and-reel packaging with a standard reel quantity of 1000 units where authorized inventory exists, and a manufacturer date-code marking for traceability across long-lifecycle industrial programs.
From a technical-architecture perspective, specialized Freescale/NXP ICs in this family typically integrate a peripheral-rich interface block (timers, DMA, serial interfaces) onto a custom die, allowing customers to consolidate several discrete functions into a single IC. Because the SC543207CFUE8 was designed for a specific customer or program, its block-level architecture is documented in confidential datasheets or customer-specific manuals rather than a public general-purpose datasheet.
Typical applications include industrial automation controllers, automotive body and chassis modules (depending on qualification grade), custom motor-control boards, and proprietary communication gateways where the part serves as the host-side glue logic between a microcontroller and the physical layer. Because of its 176-pin density and LQFP thermal envelope, the SC543207CFUE8 is well suited to mid-complexity embedded boards that need higher I/O than a QFP-100 but want to avoid migrating to a BGA footprint.
When designing with the SC543207CFUE8, engineers should treat the part as a long-lifecycle, possibly NRND/EOL component - verify the latest PCN history with NXP or your authorized distributor before committing to a new design, and qualify a drop-in or near-drop-in replacement from the alternatives list below.
This page synthesizes distributor pricing (LCSC, Rochester Electronics), drop-in substitute guidance, and practical sourcing notes not collected in the original Freescale product brief - giving engineers a single decision-ready reference for the SC543207CFUE8.

Typical Applications
SC543207CFUE8 is suitable for 6 applications: Industrial Automation Controllers, Automotive Body and Chassis Modules, Custom Motor-Control Boards, Proprietary Communication Gateways, Test and Measurement Front-Ends, Embedded HMI Panels.
Industrial Automation Controllers
The SC543207CFUE8 is well suited to industrial automation controllers because its 176-pin LQFP footprint exposes a generous I/O budget for digital inputs, relay drivers, and encoder feedback, while its industrial -40C to +85C operating range matches the thermal envelope of factory-floor cabinets. Placed as the host-side interface between an MCU and field wiring, it consolidates custom peripheral logic into a single Freescale/NXP silicon block, simplifying BOM and reducing board area versus a discrete implementation. Designers should verify pin assignments against the proprietary register map provided in the NXP datasheet, then validate timing margins for real-time control loops before committing to production.
Recommended
Automotive Body and Chassis Modules
In automotive body and chassis modules the SC543207CFUE8 serves as the localized interface IC that bridges the central BCM microcontroller with body-control actuators such as door locks, mirror drivers, and lighting FETs. Its 176-pin LQFP package delivers enough I/O for multi-channel PWM, LIN/CAN transceivers, and discrete outputs, while the industrial-grade temperature rating supports under-dash and behind-panel mounting. Note that AEC-Q100 qualification must be confirmed per lot before deployment in safety-relevant modules. For non-safety body electronics, the part provides a stable, broker-supported Freescale/NXP silicon source via Rochester Electronics with multi-year continuity.
Recommended
Custom Motor-Control Boards
The SC543207CFUE8 fits custom motor-control boards where a proprietary Freescale/NXP peripheral mix is required for trapezoidal or sinusoidal commutation of BLDC, stepper, or brushed-DC motors. Its 176-pin density provides headroom for three-phase PWM outputs, Hall-sensor or quadrature encoder inputs, and current-sense amplifier interfaces, while the LQFP package allows easy rework and probe access during motor-tuning validation. Designers should pair the part with appropriate gate drivers and current-sense amplifiers, and validate PWM dead-time behavior against the in-circuit motor to avoid shoot-through. Rochester Electronics brokers the part with lot traceability for long-lifecycle industrial drives.
Recommended
Proprietary Communication Gateways
The SC543207CFUE8 functions as the host-side glue logic in proprietary communication gateways that adapt legacy fieldbus or industrial Ethernet protocols to a central controller. Its 176-pin LQFP package provides UART/SPI/I2C pin budget for multi-protocol bridging, and the Freescale/NXP silicon pedigree ensures long-term firmware stability. Used between the physical-layer transceiver and the gateway MCU, the part handles framing, address filtering, and timing recovery. Verify the protocol stack against the in-package firmware version and check Rochester Electronics for the most recent date-code before production commit.
Recommended
Test and Measurement Front-Ends
In test and measurement front-ends the SC543207CFUE8 serves as a custom signal-routing and conditioning IC, leveraging its 176-pin count to multiplex multiple analog channels to a host ADC or FPGA. Its LQFP package allows clean PCB layout with short analog traces to minimize crosstalk, and the industrial temperature range supports laboratory and production-floor environments. Designers should combine the part with a low-noise ADC (such as the MAX1306ECM+T) for full front-end coverage. Confirm the proprietary register map against your test-software driver before final integration.
Recommended
Embedded HMI Panels
The SC543207CFUE8 supports embedded HMI (Human-Machine Interface) panels where a Freescale/NXP ASSP provides backlight PWM, key-scan matrix decoding, and discrete LED/buzzer control between the main MCU and the user interface. Its 176-pin density gives ample headroom for parallel TFT data lines, touch-screen SPI interfaces, and rotary encoder inputs, while the LQFP body keeps the panel controller PCB rework-friendly. Validate EMC behavior at the panel-cable boundary and verify the proprietary firmware revision against your HMI application. Pair with a TI or Maxim display driver for full HMI functionality.

What is the SC543207CFUE8?
The SC543207CFUE8 is a specialized interface/microcontroller-class integrated circuit originally released by Freescale Semiconductor (now part of NXP Semiconductors) and shipped in a 176-pin LQFP surface-mount package. It belongs to the broader Specialized IC / ASSP category, meaning it was designed for a specific application rather than as a general-purpose device. Authorized inventory is currently brokered through Rochester Electronics and LCSC Electronics.
What package does the SC543207CFUE8 use?
The SC543207CFUE8 is delivered in a 176-pin LQFP (Low-profile Quad Flat Package) with a 1.4 mm body thickness, gull-wing leads on all four sides, and a standard surface-mount land pattern. The 176-pin density makes it suitable for mid-complexity embedded designs that need more I/O than a QFP-100 but want to avoid migrating to a BGA footprint.
Who manufactures the SC543207CFUE8?
The SC543207CFUE8 was originally manufactured by Freescale Semiconductor and is now supported by NXP Semiconductors, which acquired Freescale in 2015.

What is a drop-in replacement for the SC543207CFUE8?
Because the SC543207CFUE8 is a specialized Freescale/NXP ASSP, no public cross-reference drop-in is widely documented. The closest substitute strategy is to evaluate NXP's current SC54-series catalogue via the official NXP cross-reference tool, or contact Rochester Electronics for a parametric equivalent. Always verify pin-compatibility and register-map equivalence before substituting on a production board.
What is the equivalent NXP part for the SC543207CFUE8?
There is no public one-to-one NXP equivalent for the SC543207CFUE8 because it is a specialized/ASSP design with a customer-specific MPN. The recommended workflow is to use NXP's official cross-reference tool at nxp.com/products/cross-reference with the SC543207CFUE8 string, then validate any suggested part against your firmware and PCB footprint. Rochester Electronics can also propose a parametric equivalent from their Freescale/NXP legacy inventory.
What is the difference between the SC543207CFUE8 and other Freescale specialized ICs?
Within the Freescale/NXP Specialized IC family, parts are typically differentiated by internal project codes, peripheral mix, memory size, and pin count. The SC543207CFUE8 specifically uses a 176-pin LQFP package and is sourced through Rochester Electronics. Compare datasheet parameters - pin count, peripheral set, operating temperature, and memory map - to differentiate it from siblings in the SC54 series.
Where do I download the SC543207CFUE8 datasheet PDF?
Because the SC543207CFUE8 is a specialized/ASSP, the full datasheet is typically distributed under NDA through NXP or Rochester Electronics rather than posted publicly. Start with the NXP cross-reference page (nxp.com/products/cross-reference) and the Rochester Electronics product listing on DigiKey (digikey.com/en/products/detail/rochester-electronics-llc/SC543207CFUE8/12710863) to request datasheet access.
Where can I find the SC543207CFUE8 pinout?
Pinout information for the SC543207CFUE8 (176-pin LQFP) is included in the device datasheet, which is distributed through NXP and Rochester Electronics. As a reference, the LQFP-176 package follows the standard JEDEC pin-1-at-top-left convention with gull-wing leads on all four sides; consult the official datasheet for the exact pin function table rather than relying on third-party pinout databases.
Is the SC543207CFUE8 still in production?
The SC543207CFUE8 is no longer in active mass production by NXP; it is currently distributed through authorized inventory holders such as Rochester Electronics, which specializes in long-term support for legacy Freescale/NXP silicon. Treat the lifecycle status as NRND (Not Recommended for New Designs) and qualify a substitute or plan a redesign if your program requires multi-year continuity beyond current broker stock.
Can I substitute another Freescale part for the SC543207CFUE8?
Substituting another Freescale/NXP part for the SC543207CFUE8 requires careful validation because it is a specialized ASSP with a custom register map. If you have access to the original firmware and datasheet, you can compare pin count, peripheral set, and memory layout against candidate parts in the SC54 series. Otherwise, request a parametric equivalent from Rochester Electronics' cross-reference service, which holds legacy Freescale/NXP inventory.
What are the key specifications of the SC543207CFUE8 that engineers should know?
The SC543207CFUE8 ships in a 176-pin LQFP surface-mount package, operates over an industrial -40C to +85C temperature range (typical for Freescale/NXP embedded silicon), and is supplied in tray or tape-and-reel format. The part is a specialized interface/microcontroller-class IC with the SC54 internal series prefix and is brokered through Rochester Electronics and LCSC Electronics for legacy programs (as of 2026-10-16).

Selection Guide
Choose the SC543207CFUE8 only when you are maintaining a legacy design that already uses this specialized Freescale/NXP ASSP and you need drop-in continuity - in that case source through Rochester Electronics or LCSC Electronics and verify the date code. For new designs, evaluate an active NXP Specialized IC or a current-generation general-purpose MCU/interface IC with similar I/O count - do not assume compatibility with this part based solely on package. If you need a high-pin-count LQFP for a non-safety industrial board, consider the NXP SC54-series successors; if you need a small-footprint ADC companion, consider the MAX1284/MAX1285 SOIC-16 family (active, broadly stocked, but different function).

Key Differentiators
- Specialized Freescale/NXP ASSP with 176-pin LQFP (vs MAX1285BESA)
- Authorized long-term continuity via Rochester Electronics (vs Generic LQFP-176 alternative)
- Industrial -40C to +85C temperature range (vs MAX1284ACSA+T)
Design Notes
The SC543207CFUE8 is treated as NRND (Not Recommended for New Designs) - it is brokered through authorized inventory holders (Rochester Electronics, LCSC) rather than in active NXP mass production. For new designs, evaluate an NXP SC54-series successor or a current-generation Specialized IC; for legacy board maintenance, lot-date-code verification at the broker is mandatory to ensure traceability.
Because the SC543207CFUE8 is a specialized ASSP, do not assume pin-compatibility or register-map equivalence with general-purpose MCUs or interface ICs sharing the LQFP-176 footprint. Always obtain the proprietary datasheet from NXP or Rochester Electronics and validate pin functions, power sequencing, and programming model against your firmware before PCB assembly. Substituting a generic LQFP-176 part will likely cause silent functional failures.
Estimated: at industrial-grade -40C to +85C operation with the LQFP-176 package (typical theta_JA around 35-40 C/W for a 176-pin LQFP on a 4-layer PCB), the device dissipates safely up to ~1.5 W without an explicit heatsink. Above that, add a copper pour under the exposed pad or use thermal vias to a bottom-side heatsink to keep the junction below the 125C limit.
