The Freescale Semiconductor (now NXP Semiconductors) SC8541EVTAQF is an obsolete legacy microprocessor IC (MPU) offered through authorized stockists such as Rochester Electronics. Originally a Freescale PowerPC-era communications processor, the SC8541EVTAQF is classified as a specialized telecom/embedded microprocessor. As of 2026-10-16, distribution is limited to excess inventory from authorized partners; no active manufacturing is occurring. A microprocessor IC (MPU) is an integrated circuit that contains the central processing unit, control logic, and often peripheral interfaces of a computing system on a single die. Within the broader taxonomy, an MPU belongs to microprocessors -> integrated circuits (ICs) -> embedded semiconductors, sitting alongside microcontrollers (MCUs), DSPs, and ASICs. Legacy MPUs such as the SC8541EVTAQF were designed for fixed-function telecom infrastructure where long lifecycle, deterministic behavior, and software stability outweighed raw compute performance. Key features include its original communications-processor architecture optimized for telecom line-card and channel-bank applications, plus continued availability through Rochester Electronics as a franchised distributor. Because the original datasheet is no longer publicly hosted by NXP, exact electrical parameters such as core voltage, I/O count, and process node cannot be confirmed and are flagged in the specifications list. Technical depth: the part belongs to Freescale's SC85xx communications-processor family, which historically integrated PowerPC cores with on-chip telecom peripherals. Engineers using this part today typically do so for maintenance of legacy equipment where redesign is cost-prohibitive. Typical applications include telecom line cards, legacy channel banks, industrial control modules requiring long-term parts continuity, and military/aerospace sustainment programs. It is also used by aftermarket refurbishers of legacy networking gear. When designing with this device, note that no new silicon is being fabricated; all supply is from existing authorized stock. Buyers should confirm RoHS/REACH status and date code with the supplier before placing production orders. This page consolidates authorized distributor listings, parametric gaps flagged as [DATA_NEEDED], and replacement guidance not found on the original manufacturer datasheet - information designed to help sustain-program engineers source and qualify this legacy MPU.

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

It is part of the S08QG sub-family of low-pin-count MCUs designed for cost-sensitive embedded applications. The device operates from a wide supply range and integrates multiple peripherals aimed at simplifying BOM in small-form-factor designs. What is an 8-bit microcontroller? An 8-bit MCU is a small, self-contained computer-on-a-chip that executes instructions on 8-bit-wide data paths. It belongs to the broader category of microcontrollers -> embedded microcontrollers -> microprocessors -> semiconductors. The S08QG family specifically sits at the low-cost, low-power end of NXP's HCS08 lineup, offering S08 CPU performance with peripheral integration to minimize external component count. 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.

Technically, the SCF5250LAG100 combines a ColdFire V2 core, configurable peripherals, and audio decoder engine in a single ROMless IC; designers typically pair the part with external Flash and SDRAM for program and data storage. The eMAC allows efficient fixed-point DSP for audio decoding algorithms (MP3, WMA, OggVorbis) without an external DSP chip. Typical applications include portable MP3/audio players, automotive head units supporting CD and HDD-based audio, USB audio peripherals, and industrial control systems. According to NXP product page information, the integrated peripherals and eMAC allow the SCF5250 to replace both the microcontroller and the DSP in certain applications. When designing with this part, consider that ROMless operation requires external boot memory (typically SPI NOR Flash) and proper bus termination. The 144-pin LQFP layout with 20x20 mm body requires careful PCB escape planning for the SDRAM bus.

SCIMX516AJM6CR2 - i.MX51 32-Bit ARM Cortex-A8 MPU | NXP

The NXP Semiconductors SCIMX516AJM6CR2 is an i.MX51 32-bit microprocessor unit (MPU) based on an ARM Cortex-A8 core and supplied in a 6-6 mm MAPBGA package identified by JM6. The verified source data identifies the device as an embedded microprocessor rather than a conventional microcontroller. No verified core frequency, memory size, I/O map, operating-voltage range, pinout, or package drawing was supplied, so those values must be confirmed from the applicable i.MX51 manufacturer documentation before hardware release. An MPU is an application processor that executes an operating system or embedded control software and integrates a CPU core with memory and peripheral interfaces. The ARM Cortex-A8 instruction-set architecture provides the compute foundation, while the surrounding i.MX51 devices provide the interfaces required for communications, storage, graphics, and control. Within the embedded-processor hierarchy, an MPU sits above a microcontroller in typical software and system complexity because an MPU commonly supports richer operating systems, external memory, and higher-bandwidth peripheral networks. The verified listing describes SCIMX516AJM6CR2 as an i.MX51 32-bit MPU with an ARM Cortex-A8 core. The JM6 package code indicates a compact surface-mount Ball Grid Array implementation, but its exact ball count and ball map are unavailable in the supplied sources. Consequently, this page does not infer CPU speed, RAM, external-memory interfaces, GPIO count, or peripheral selections. Legacy i.MX51 variants can differ materially in memory and interface configuration, making exact orderable-part verification essential. Potential uses include industrial human-machine interfaces, building controls, media panels, networked embedded equipment, and compact control terminals. In each case, the processor can serve as the system controller when the board provides the required memory, storage, networking, display, and power circuitry. Compared with an MCU-only design, an MPU approach supports a more capable software environment, but it also demands platform-specific boot support, operating-system integration, and careful high-speed layout. Before design-in, obtain the exact NXP or Rochester Electronics datasheet and inspect the lot-specific ordering code. Verify the exposed-pad connection, PCB land pattern, multilayer-routing constraints, power rails, decoupling, clocking, boot configuration, and software-supported device revision. Do not reuse an i.MX6, i.MX53, or generic BGA layout as a substitute because package identifiers and ball assignments must be proven identical. This page consolidates verified distributor identity, package-code, RoHS indication, sourcing links, and documented replacement-search results. Missing technical parameters are explicitly marked rather than inferred, allowing engineers to compare procurement data while completing the mandatory manufacturer-documentation review before design release.

The Cortex-A8 core inside the i.MX53 implements the ARMv7-A architecture with NEON SIMD and VFPv3 floating-point units, providing single-core performance suitable for mid-range embedded graphical interfaces, video decoding, and industrial control panels. Key features include the ARM Cortex-A8 core at 1.0 GHz, hardware-accelerated video engines (VPU, GPU), and a rich peripheral set including two CAN controllers, USB 2.0 with integrated PHY, 10/100 Ethernet MAC, SATA-II, NAND/NOR flash controllers, and an LCD controller supporting WXGA resolution. The integrated power management unit (PMU) provides multiple voltage domains to optimize active and standby power consumption, with deep-sleep modes suitable for always-connected industrial designs. The 529-pin FC-PBGA delivers high I/O density while supporting the thermal dissipation needs of a 1 GHz Cortex-A8 device under full multimedia load. The architecture combines a 32 KB L1 instruction cache, 32 KB L1 data cache, and a 256 KB unified L2 cache, providing the memory bandwidth needed for full HD video and complex HMI rendering. On-chip connectivity includes multiple UART, SPI, I2C, and I2S ports, enabling direct interfacing with audio codecs, touch controllers, sensors, and external wireless modules. The multimedia-focused silicon delivers hardware-accelerated 720p H.264 decode, JPEG decode, and 2D/3D graphics acceleration via the integrated GPU, reducing CPU load and power consumption. Typical applications include industrial HMI panels, point-of-sale (POS) terminals, automotive infotainment secondary displays, medical patient monitoring equipment, smart home control panels, and portable data acquisition devices. The wide operating temperature range and long-term NXP product support make the i.MX53 especially suitable for industrial designs with multi-year lifecycles. The 529-ball FC-PBGA package is also compatible with the broader i.MX53 family, allowing board-level reuse across i.MX535, i.MX536, and i.MX537 derivatives that scale core count or peripheral mix. When designing with the i.MX53, ensure the PCB stackup supports the 0.8 mm pitch BGA escape and the 0.4 mm pitch PoP memory footprint without requiring microvia cost escalation. The PMIC companion (such as the NXP PF0100) must be selected to supply the correct voltage sequence required by the i.MX53's internal rails during boot, otherwise the device may latch into a non-recoverable state. Plan for at least 1.5 A on the core rail to support peak Cortex-A8 load plus GPU activity without triggering thermal shutdown.

[DATA_NEEDED: core function summary, operating frequency, supply voltage] According to verified distributor listings (JLCPCB Assembly), the part is catalogued as an LQFP-216-EP(24x24) SMT, ROHS component under the JLCPCB Assembly brand/C9900214951 listing. A system-on-chip integrates a processor core, memory controllers, peripheral interfaces, and often mixed-signal blocks onto a single die, sitting at the top of the semiconductor hierarchy: SoC -> integrated circuit -> semiconductor device. SoCs reduce board area, bill-of-materials count, and system power compared with multi-chip solutions, which is why they dominate consumer, industrial, and communication equipment designs. [DATA_NEEDED: key features]. Verified public data for this MPN is limited: the confirmed attributes are the 216-lead LQFP exposed-pad package, 24x24 mm body size, surface-mount mounting, and RoHS compliance. Engineers evaluating this part should download the official Nuvoton datasheet for core architecture, clock speeds, memory configuration, I/O voltage levels, and power consumption figures. The most consequential verified fact about the SCM605C2S2 is its lifecycle status: Nuvoton has issued a Product End-of-Life notice (Ineltek, June 2026). Last time buys were offered through July 31, 2026, orders are non-cancelable and non-returnable, and scheduled deliveries must complete on or before June 30, 2027. New designs should not adopt this part. For existing designs, the practical applications are sustaining production of end-of-life products, repair and service stock, and last-time-buy inventory bridging until a redesign to a current-generation Nuvoton or third-party SoC is complete. Design consideration: because the device is discontinued, any remaining design activity should focus on lifetime-buy sizing, authorized-distributor stock capture, and second-source qualification rather than new product integration. Verify remaining last-time-buy windows with your distributor before committing schedules. This page synthesizes distributor listings, the official EOL notice, and lifecycle guidance not consolidated in the manufacturer datasheet, giving engineers a single verifiable reference for the SCM605C2S2.
