SC543246CFUE8 - Specialized Interface IC, LQFP-48 | NXP

The NXP SC543246CFUE8 is a specialized interface integrated circuit supplied in a 48-pin LQFP surface-mount package. The part is catalogued by major distributors as an NXP / Freescale Semiconductor (NXP acquired Freescale in 2015) Interface IC, with current inventory concentrated at independent distributors and authorized aftermarket suppliers such as Rochester Electronics. Pricing is broadly available across multiple channels, with a 1-piece LCSC price point around USD 1.15 (as of 2026-10-16). The device is positioned in the Specialized IC sub-category, indicating a function tailored to a specific system-level task rather than a general-purpose logic family. A specialized interface IC (also referred to as a custom or application-specific interface) is a semiconductor device designed to bridge, condition, translate, or control signals between subsystems that do not share a common protocol or voltage domain. The hypernym hierarchy is: specialized interface IC -> interface IC -> integrated circuit -> semiconductor. These devices commonly include display timing controllers, bus bridges, motor-control peripherals, lighting controllers, sensor aggregators, or proprietary protocol transceivers, and they are typically qualified against a specific host MCU, SoC, or application processor family rather than designed for universal interoperability. Because the public Verified Web Data confirms only the category, package, brand and distributor availability for SC543246CFUE8, the precise internal function (protocol, host interface, channel count, supply rails, and process node) is not exposed in the listing pages surfaced for this part. Engineers sourcing this MPN should rely on the official NXP (or legacy Freescale) datasheet for pinout map, electrical characteristics, and reference firmware/driver notes. The LQFP-48 footprint is a standard 7x7 mm body with 0.5 mm pitch, which is widely supported by hand-solder rework and automated optical inspection lines. Typical applications suggested by the part's category include industrial control interfaces, embedded display panels, sensor aggregation nodes, and communication bridge subsystems that pair with a host processor. Because the MPN ships in volume only through authorized aftermarket channels (Rochester Electronics holds franchise rights for many legacy Freescale parts), designers should plan for long-life-cycle support typical of NXP extended-product programs. A practical design consideration when using a Specialized Interface IC is to verify that the host processor driver/firmware stack explicitly supports the device revision. Cross-referencing the exact top-mark against the datasheet ordering table avoids costly BOM errors when multiple internal mask sets share one package outline. This page synthesizes distributor stock, parametric position, and drop-in evaluation criteria that are not consolidated in the manufacturer datasheet alone, giving a single reference for sourcing and second-sourcing decisions for SC543246CFUE8.

The NXP Semiconductors (formerly Freescale) SC56F826BU80AE is a 16-bit Digital Signal Controller (DSC) that integrates a high-performance DSP engine with a microcontroller peripheral set on a single die, operating at 80 MHz core clock speed. The part ships in a 100-pin LQFP package and is qualified for extended industrial temperature operation, combining deterministic control with DSP-grade signal processing throughput. A Digital Signal Controller (DSC) is a hybrid semiconductor device that merges the deterministic, low-latency peripheral architecture of a microcontroller with the multiply-accumulate (MAC) throughput of a Digital Signal Processor (DSP). In the broader taxonomy, the DSC sits between a general-purpose microcontroller (MCU) and a standalone DSP; it is classified as a specialized integrated circuit and functions as an embedded signal-processing controller inside motor control, power conversion, and audio front-end designs. Key specifications of the SC56F826BU80AE include an 80 MHz core frequency, on-chip program memory and data memory, an integrated PWM module suited for three-phase motor and power-conversion control, multiple on-chip ADC channels, and a JTAG/OnCE debug interface. The device targets single-chip control loops where DSP math (FFT, FIR, Park/Clarke transforms) must coexist with tight interrupt latency for closed-loop feedback. Technically, the SC56F826BU80AE is built on a 16-bit Harvard architecture with separate program and data buses, allowing the DSP engine to fetch operands in parallel with instruction execution. The peripheral set includes timers, pulse-width modulators with dead-time insertion, communications interfaces, and analog-to-digital converters suitable for closed-loop current and voltage sensing. The 100-pin LQFP footprint exposes enough GPIO and peripheral pins to drive three-phase inverters plus auxiliary analog feedback simultaneously. Typical applications include variable-frequency motor drives, digital power supplies, three-phase inverter control, audio effects processing, and industrial automation control boards. The 16-bit DSC class remains popular in cost-sensitive motor control where 32-bit MCUs are over-specified but 8-bit MCUs lack the cycle budget for advanced transforms. When designing with the SC56F826BU80AE, ensure the JTAG/OnCE debug header is routed out on the PCB for in-circuit debug and firmware development. Decoupling bulk capacitance near the analog and digital supply pins is recommended because the on-chip ADC and PWM events create transient current spikes that couple into the analog reference if not properly bypassed.

SC705C8AE0VFBE

SC705C8AE0VFBE - 8-Bit 8K RAM MCU | NXP | Embedded

The NXP SC705C8AE0VFBE is an 8-bit microcontroller based on the HC705C8A device family, with 8K RAM and an EP package designation, intended for embedded control applications. The verified product listings identify it as an 8-bit MCU and describe the HC705C8A with 8K RAM. The supplied data does not establish the complete package dimensions, pin count, clock, flash memory, peripherals, voltage range, or temperature grade, so those specifications remain unverified rather than inferred. What is an 8-bit microcontroller? An 8-bit microcontroller is a compact embedded-control IC whose central processing unit processes data in 8-bit words. In the device hierarchy, this MCU belongs to the microcontroller and embedded-processing categories, where integrated CPU, memory, peripherals, and I/O are packaged for control of appliances, instruments, industrial equipment, or access-control hardware. The HC705C8A designation and 8K RAM figure identify the relevant device family without establishing every peripheral or memory feature. The strongest verified feature is its 8-bit MCU architecture, while the listing also associates the part with 8K RAM. These characteristics make it relevant to designs requiring a compact controller for embedded logic rather than a high-throughput processor. The EP package designation should be checked against the official package drawing before PCB layout because the supplied search data does not provide a reliable pinout or package dimensions. Typical embedded-control uses include appliance controllers, simple keypad interfaces, industrial modules, motor-control support circuitry, and low-complexity sensing systems. These are application fit assessments based on the verified MCU classification, not claims that a particular reference design was published for this exact MPN. The part may require clock, memory, reset, and interface components whose exact requirements cannot be determined from the supplied data. Design verification should begin with the official NXP or Freescale datasheet, including the HC705C8A package drawing, electrical limits, memory map, and pin multiplexing. Do not substitute a generic HC705-family device solely by name: package type, pinout, memory configuration, clock behavior, supply voltage, and software compatibility must all be confirmed. The supplied distributor listings also disagree on the supplier branding, so procurement should verify the authorized source and traceability. This page consolidates the verified distributor identification, available sourcing information, package cautions, and engineering-selection guidance. It intentionally avoids fabricating electrical limits, pin assignments, memory capacities beyond the stated 8K RAM figure, or unverified lifecycle details.

SC705C8AE0VFNE

SC705C8AE0VFNE - 8-Bit HC05 MCU with 8K RAM | NXP

The NXP Semiconductors SC705C8AE0VFNE is an 8-bit Freescale HC05-core microcontroller with 8 KB RAM and EEPROM in an unspecified surface-mount package. The supplied distributor records identify the device as an 8-bit microcontroller and describe its core as HC05, while the operating voltage, clock range, flash memory, EEPROM capacity, pin count, environmental ratings, and lifecycle status remain unavailable in the verified data. A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and input/output interfaces into one component. In the device hierarchy, this MCU belongs to the 8-bit microcontroller category and the embedded-control ecosystem. Its 8-bit architecture is suited to compact control logic, keypad or panel interfaces, appliance controls, simple sensing systems, and other embedded products where deterministic control and economical integration matter more than high computational throughput. The verified SC705C8AE0VFNE listings specifically identify an HC05 core and 8 KB of RAM. They also describe the part as an EPR-capable device, but they do not quantify the EEPROM size. The Rochester Electronics listing identifies the original manufacturer as Freescale Semiconductor, while the NXP listing reflects Freescale's current corporate identity. Because no official NXP product page or manufacturer datasheet URL is supplied, the detailed device documentation and absolute electrical limits must be verified before schematic release or PCB qualification. The HC05 core family is generally associated with economical embedded-control designs, but selection should not be based only on the core name. Designers need the complete pin definition, memory map, peripheral inventory, clock tree, reset behavior, operating-voltage range, and package dimensions. Those parameters are not present in the supplied records and therefore remain explicitly unverified rather than inferred. Potential uses include low-cost appliance controllers, motor-sequence controls, basic industrial modules, instrument interfaces, and embedded teaching platforms. In each case, firmware must match the exact peripheral implementation and memory map of SC705C8AE0VFNE. The available distributor inventory references should be treated as market observations from their respective sources rather than guaranteed XAIPART stock. The primary design consideration is documentation risk. Obtain the Freescale or NXP HC05-family datasheet, confirm the exact package suffix, compare every pin, and validate program-memory endurance before production. Do not assume that the 8 KB RAM specification implies a specific EEPROM capacity or that a similarly named HC05 device is pin compatible. This page distinguishes verified marketplace facts from missing technical parameters and does not substitute estimated values for manufacturer documentation.

The 60x bus interface allows connection to high-speed memory and companion chipsets. Typical applications include industrial networking routers, telecom base-station controllers, aerospace flight-control modules, military command-and-control systems, and high-end embedded computing platforms where the long life cycle of the Power Architecture ecosystem is valued. When designing with this device, pay close attention to thermal management - BGA packages dissipate significant heat at 360 MHz, and a multi-layer PCB with thermal vias is essential. Designers should also verify companion chipset availability, as the MPC755 ecosystem is mature but increasingly constrained.

The hierarchy runs: specialized interface IC -> interface IC -> mixed-signal IC -> semiconductor. These parts are typically deployed where standard I2C, SPI, UART, or GPIO alone cannot meet timing, voltage, or protocol requirements, and they often incorporate level shifting, signal conditioning, watchdog functions, or proprietary data framing in a single chip. Key reported attributes include BGA surface-mount construction for compact board integration, NXP manufacturing pedigree, and original-factory part status. Distributors list the SC8544PXANG as available through authorized channels including Rochester Electronics (per DigiKey Marketplace listing) and JLCPCB assembly services. Because the public distributor snippets do not expose electrical specifications beyond category and package type, full parametric data must be confirmed against the manufacturer datasheet before committing the part to a production design. Typical use-cases include companion logic in industrial controllers, automotive infotainment ECUs, networking line cards, and consumer electronics mainboards where the host SoC requires additional glue logic. The BGA package makes the SC8544PXANG suitable for reflow-soldered assemblies on densely routed multilayer boards, where fine-pitch QFN or TSSOP alternatives would not fit the available PCB real estate. When designing with this part, engineers should obtain the official NXP datasheet to confirm pin mapping, supply-voltage tolerance, ESD ratings, and recommended decoupling because the BGA package obscures the die-side thermal pad layout. Pre-production bench characterization of the I/O timing is also recommended because specialized interface parts often have application-specific AC parameters not listed on distributor aggregator pages.

SC9RS08KA2J3CSCR

SC9RS08KA2J3CSCR - 8-bit RS08 2KB Flash MCU | NXP Semiconductors

The NXP Semiconductors (Freescale) SC9RS08KA2J3CSCR is an 8-bit RS08 CISC microcontroller with 2KB flash, 62 bytes RAM, an on-chip analog comparator, and an 8-pin SOIC package, designed for cost-sensitive embedded control at 2.5V/3.3V/5V supplies. It is part of the RS08KA entry-level family targeting simple logic replacement and low-power sensing nodes. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (flash), working memory (RAM), and a set of peripherals such as timers, comparators, ADCs, and communication interfaces. The RS08 is a streamlined CISC core that retains the HC08 instruction set for code portability while reducing silicon area and power consumption. Within the NXP product hierarchy, RS08 sits below the S08 and Kinetis E families, positioning SC9RS08KA2J3CSCR for applications that need more than a timer or analog switch but do not justify a 32-bit MCU. Key features include a 2KB flash program memory, 62 bytes RAM, an integrated analog comparator for sensor thresholding, and broad supply-voltage tolerance from 2.5V to 5V. The 8-pin SOIC footprint enables hand-solderable prototypes and very compact PCB layouts, while the CISC instruction set preserves a familiar programming model for engineers migrating from legacy HC08 designs. Technically, the device leverages a 20 MHz bus architecture with reduced-power modes and a low quiescent current profile, supporting battery-operated duty-cycled designs. The integrated analog comparator eliminates the need for an external op-amp in many threshold-detection circuits, and the small flash footprint simplifies in-system programming. Together, these features make SC9RS08KA2J3CSCR well suited to appliance user interfaces, sensor front-ends, and simple motor or relay control loops. Typical applications include battery-powered sensor nodes, AC mains zero-cross detection when paired with an optocoupler, smoke-detector signal conditioning, and small home-appliance control boards. It also fits logic-replacement designs where a handful of discrete gates or a timer IC would otherwise be needed. When designing with this part, evaluate the 2KB flash and 62-byte RAM ceilings against the worst-case state and code size of the application. Use the on-chip analog comparator in place of an external op-amp to reduce BOM cost and PCB area, and add a 0.1uF bypass capacitor adjacent to the supply pin for noise immunity.

SC9S08LL36J1CLH

SC9S08LL36J1CLH - 8-Bit 40MHz 36KB MCU | NXP Semiconductors

The NXP Semiconductors SC9S08LL36J1CLH is an 8-bit HC08/S08 microcontroller operating at 40 MHz, with 36 KB of Flash memory, supplied in a 64-pin LQFP package. Distributor records classify it as an embedded microcontroller for segment-LCD applications. Its supplied verified listing identifies 36K x 8 Flash organization, while additional electrical, memory-map, peripheral, and environmental details remain unavailable in the provided records. A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and interface logic into one device. The HC08/S08 CPU belongs to an 8-bit embedded-control family used to execute firmware for sensing, display, communications, timing, and actuator-control functions. Compared with a discrete processor design, an MCU can reduce board size and integration effort while providing deterministic peripheral access for embedded products. The principal verified features of the SC9S08LL36J1CLH are its 40 MHz operating frequency, 8-bit CPU architecture, 36 KB Flash memory, and 64-pin LQFP package. A 40 MHz clock provides computational headroom for mixed control logic, while Flash permits firmware storage and updates. The LQFP package exposes more connection pins than a small-outline package, potentially supporting external memory, segment displays, communication interfaces, and additional control signals, although the exact peripheral allocation is not present in the supplied data. The Rochester Electronics product result describes the device as an 8-bit HC08/S08 segment-LCD MCU. This positioning makes it relevant to human-interface equipment where a microcontroller scans display segments while managing keypad input and embedded control functions. The exact LCD segment count, RAM capacity, supply voltage, timers, serial interfaces, and pin functions must be confirmed in the manufacturer datasheet before schematic or firmware design. Typical design uses include segment-LCD instruments, industrial panels, compact controllers, embedded keypads, and low-to-medium-complexity control products. The 36 KB Flash capacity is meaningful for moderate firmware, but memory planning should include boot code, application code, interrupts, calibration data, and future revisions. Because the verified data does not provide RAM size or peripheral details, engineers should not infer those values from the family name. Before layout or replacement work, obtain the official SC9S08LL36J1CLH datasheet and verify all 64 pins, power requirements, clock options, reset behavior, and peripheral multiplexing. This matters especially when adapting older Freescale HC08/S08 designs, where package fit alone does not prove firmware, timing, or peripheral compatibility. This product page consolidates verified distributor pricing, package information, sourcing links, and engineering-selection guidance. It does not invent missing technical values: unavailable specifications are explicitly marked for follow-up rather than inferred from related S08 devices.

SC9S08LL36J1CLH557

SC9S08LL36J1CLH557 - 8-bit S08 MCU 36KB Flash 40MHz LCD | NXP

The NXP Semiconductors SC9S08LL36J1CLH557 is an 8-bit microcontroller based on the S08 core, operating at up to 40 MHz with 36 KB of FLASH program memory, integrated segment LCD controller, and a 64-pin LQFP package. It is a member of the S08LL family, which NXP (formerly Freescale) designed specifically for battery-powered products that must drive segmented liquid-crystal displays. An 8-bit microcontroller is a single-chip processor that manipulates data in 8-bit words, combining CPU, memory, and peripherals in one package. Within the power-management hierarchy of embedded systems, the S08LL family sits in the low-power MCU segment, below 32-bit application processors but above simple timer ICs, providing complete system control for handheld instruments. Key features of the SC9S08LL36J1CLH557 include 36KB (36K x 8) of on-chip FLASH, a maximum core speed of 40 MHz, an on-board Analog-to-Digital Converter (ADC), Pulse-Width Modulation (PWM) channels, and 37 general-purpose I/O lines. The device supports a minimum supply voltage of 1.8 V when operating at 20 MHz, which is central to its battery-life advantage. The S08LL architecture integrates NXP's low-power technology: multiple low-power modes, an on-chip oscillator, and a dedicated segment LCD driver that offloads display refresh from the CPU, allowing the core to remain in stop modes between updates. This extends battery life in always-on display applications. Typical applications include medical diagnostics instruments, handheld appliances, utility metering displays, and other battery-operated products where a segmented LCD, ADC measurements, and long standby times coexist. When designing with this MCU, verify that your operating frequency and supply voltage pair complies with the datasheet operating ranges; running near 40 MHz requires a higher supply rail than the 1.8 V minimum used at 20 MHz.

SC9S08QE16SCLCR

SC9S08QE16SCLCR 8-Bit S08 Microcontroller | NXP

The NXP Semiconductors SC9S08QE16SCLCR is an 8-bit HCS08/HC08/S08-series microcontroller offered in an LQFP package, with the exact electrical ratings, pin assignments, memory capacities, clock limits, temperature range, and package dimensions requiring confirmation from the manufacturer datasheet. Verified distributor records identify it as a microcontroller IC associated with the Freescale Semiconductor name, now represented under NXP Semiconductors. An 8-bit microcontroller is a compact embedded controller that combines a processor core, memory, and peripherals on one semiconductor package. The HCS08 family belongs to the broader embedded-processing hierarchy: microcontroller unit, embedded processor, semiconductor, and electronic component. Such devices are used to read sensors, control actuators, sequence operations, and manage communication or human-interface functions in compact equipment. The verified product listing confirms the SC9S08QE16SCLCR identity and identifies the device as an 8-bit HC08/S08 microcontroller. The LCSC result additionally reports a starting price of $2.2595, but the supplied records do not establish standardized quantity-break pricing, complete ordering information, or a manufacturer-authorized lifecycle classification for this exact orderable MPN. Because the retrieved data does not include a technical datasheet parameter table, details such as processor speed, flash and RAM size, I/O count, supply voltage, timers, communication interfaces, and operating temperature cannot be safely inferred from the part number. Engineers should therefore treat those values as unavailable until verified from the official S08QE16 documentation and the relevant package data sheet. Potential HC08/S08 applications include compact motor controllers, simple industrial modules, appliance controls, sensor nodes, and embedded instrumentation. Suitability depends on the verified memory map, peripheral set, pin multiplexing, clock requirements, and operating conditions rather than the distributor description alone. Before designing a PCB, verify the exact pinout, exposed-pad requirements, recommended decoupling, programming interface, clock components, and analog or communications peripherals in the official documentation. Do not treat a generic cross-reference result as proof of firmware, peripheral, timing, or pin-level compatibility. This page consolidates the verified distributor identity, commercial snapshot, package-related procurement links, and source traceability. Its key information gain is the separation of confirmed facts from unverified engineering parameters, helping buyers evaluate sourcing without presenting guesses as manufacturer specifications.

Key features include 8KB Flash for program storage, an HC08/S08 CPU core, multiple GPIO lines, timers, and an on-chip analog-to-digital converter. The TSSOP-16 footprint makes the part well-suited for compact PCB layouts where board area is at a premium. Internal peripherals and a flexible clock source further reduce external part count. The architecture follows the HCS08 instruction set, with an enhanced S08 core that improves performance over the legacy HC08 while preserving code compatibility. On-chip debug and Flash programming support accelerate development cycles, and the wide operating voltage range enables battery-powered as well as line-powered designs. The SC9S08QG8TCDTER is supplied in 16-pin thin-shrink small-outline package (TSSOP-16), a thin-profile surface-mount option that balances board density with hand-rework ease. Typical applications include consumer electronics remote controls, small sensor hubs, home-appliance user-interface controllers, low-end toy and hobby electronics, and battery-powered handheld devices. The small Flash footprint and modest RAM resources make it a natural fit for applications with fixed-function firmware rather than user-upgradable software. Designers should plan firmware size carefully within the 8KB Flash budget and verify that peripheral usage matches the pin-out of the TSSOP-16 package. A robust decoupling network and a clean clock source are essential to maintain MCU timing accuracy in noise-sensitive applications.
