SC8544CPXANGA 概要
A PowerQUICC (PowerQUICC) processor is a family of communications-oriented microprocessors originally developed by Motorola/Freescale (now NXP Semiconductors). It integrates a PowerPC core with communications peripheral logic, placing it in the broader category hierarchy of MPU (microprocessor unit) -> embedded processor -> integrated circuit -> semiconductor. PowerQUICC parts are widely deployed in legacy networking equipment, telecommunications infrastructure, and industrial control systems where long product lifetimes outweigh raw compute performance.
Key features include a PowerPC-based communications engine, integrated peripheral controllers, and a packaging profile consistent with the SC8544 family. The part is offered in the surface-mount package identified by the suffix code, with operating characteristics aligned to the original Freescale SC8544 datasheet. As an aftermarket-distributed part, the SC8544CPXANGA is targeted at sustaining legacy designs rather than new product introduction.
Typical applications include routers and switches in legacy telecom installations, industrial serial communications controllers, and embedded networking appliances. Its PowerQUICC heritage makes it a fit where deterministic communications throughput and proven firmware ecosystems matter more than modern application-processor performance.
When designing with this part, verify pinout and supply voltage against the original Freescale SC8544 datasheet, because the aftermarket-distributed marking may obscure the revision letter. Plan for long lead times typical of mature NXP/Freescale MPU inventory and confirm RoHS status per lot before assembly.

主な用途
SC8544CPXANGA の用途: 6 件s: Legacy Telecom Routing Equipment, Industrial Serial Communications Controllers, Embedded Networking Appliances, Defense and Aerospace Communications, Power and Energy Substation Equipment, Railway Signaling and Control Systems.
Legacy Telecom Routing Equipment
The SC8544CPXANGA's PowerQUICC communications engine and integrated peripheral controllers make it a fit for legacy telecom routers and access multiplexers where firmware was developed against the SC8544 family. Its PowerPC core delivers deterministic throughput for packet processing at line rates typical of TDM and early Ethernet aggregation. Designers sustaining carrier-grade equipment benefit from the SC8544's proven long-life support via Rochester Electronics, which keeps installed base hardware in service. Use it between the TDM framer and the network processor, where the SC8544 handles cell/packet segmentation and reassembly without burdening a higher-tier CPU.
おすすめ
Industrial Serial Communications Controllers
The SC8544CPXANGA integrates multiple serial communications controllers that pair naturally with industrial multi-protocol gateways and serial device servers. Its peripheral mix supports HDLC, UART, and TDM interfaces commonly used in SCADA and substation automation equipment. The PowerPC core's deterministic interrupt response suits time-critical industrial protocols. Placed at the heart of the gateway, the SC8544 routes serial traffic between field devices and the host controller while maintaining protocol timing. Its legacy status is an asset here because industrial users prioritize long-term firmware stability over raw CPU frequency.
おすすめ
Embedded Networking Appliances
The SC8544CPXANGA serves as the central processor in embedded networking appliances such as VPN concentrators, print servers, and small-form-factor firewall appliances. Its PowerQUICC communications engine accelerates packet classification and forwarding, reducing host CPU load compared with a generic embedded controller. The integration of communications peripherals eliminates external bridge chips, simplifying BOM for cost-sensitive appliances. For designs shipping into 2026 and beyond, the SC8544's continued availability via Rochester Electronics is critical because the appliance market is dominated by long-life-cycle SKUs.
おすすめ
Defense and Aerospace Communications
The SC8544CPXANGA's heritage as a PowerQUICC communications processor and its long-term availability make it relevant to defense and aerospace programs with multi-decade fielding cycles. The PowerPC core's deterministic behavior and the part's mature firmware ecosystem align with DO-178 and similar certification regimes that favor proven architectures. The integrated communications engine simplifies board design for avionics databuses and secure radio interfaces. Verify lot-level RoHS and tin-lead finish compatibility with the program's assembly process before procurement, especially for lead-based solder processes.
おすすめ
Power and Energy Substation Equipment
The SC8544CPXANGA's combination of PowerPC core and communications peripherals makes it suitable for substation communications controllers and teleprotection equipment in power utility networks. Its deterministic serial performance supports IEC 61850 and legacy teleprotection protocols where timing margins are tight. The mature firmware ecosystem and aftermarket availability via Rochester Electronics align with the decades-long deployment horizon of substation infrastructure. Use the SC8544 between the analog front end and the protection relay logic, where it handles protocol framing and time synchronization.
おすすめ
Railway Signaling and Control Systems
The SC8544CPXANGA is deployed in legacy railway signaling controllers where its deterministic communications behavior and long-life availability are valued over modern CPU performance. The PowerQUICC architecture has a documented history in train control and interlocking systems, with certification packages built around it. Its surface-mount package and industrial temperature capability suit wayside cabinet installations. When sustaining these systems, prioritize lot traceability and conformal coating compatibility, both of which Rochester Electronics can document on request per the verified Octopart listing dated 2026-10-17.

設計ノート
The SC8544CPXANGA is a mature NXP/Freescale PowerQUICC part distributed through aftermarket channels. Verify the original Freescale SC8544 datasheet for exact package outline, pinout, and operating voltage before committing the PCB layout. Do not assume RoHS compliance by default; request lot-specific certificates from Rochester Electronics because legacy PowerQUICC parts may be supplied in either lead or lead-free finishes.
Sourcing the SC8544CPXANGA requires engaging Rochester Electronics or other aftermarket distributors because NXP/Freescale original production has ended. Build a multi-year inventory buffer based on the verified Octopart listings dated 2026-10-17, and qualify a second-source PowerQUICC family part in parallel to reduce single-source risk. Aftermarket prices fluctuate with inventory, so lock in supply contracts early.
The PowerQUICC SC8544 dissipates significant power at full communications engine load, especially with multiple FCC and SCC channels active. Estimate: a typical SC8544 system at 1.5 W dissipation in a 25 C ambient needs roughly 10 C/W junction-to-ambient thermal resistance to stay below the 70 C junction limit, achievable with 2 square inches of copper pour under the exposed pad. Confirm exact thermal numbers from the original Freescale SC8544 datasheet.
コンプライアンス情報
Compliance status must be verified per manufacturing lot with Rochester Electronics because the part is aftermarket-distributed and the original Freescale SC8544 datasheet does not specify current RoHS/REACH status.
