SCN8548EVTAUJD 概要
A PowerQUICC III SoC is a communications processor family that combines a Power Architecture CPU core with high-bandwidth networking and interconnect peripherals, falling within the broader taxonomy of embedded communications processors -> microprocessors -> integrated circuits -> semiconductors. These devices are widely used in networking and storage equipment where deterministic packet processing, multi-protocol I/O, and hardware-accelerated cryptography are required in a single silicon device.
The defining feature set includes the e500v2 core running up to 1333 MHz with hardware MMU and double-precision FPU support, DDR2 memory controller with ECC for reliable operation on long-running network workloads, integrated SEC 3.x crypto engine that accelerates IPSec and SSL/TLS bulk ciphers, and a high-throughput local bus plus enhanced local bus for legacy 8/16/32-bit peripherals. The SoC supports simultaneous operation of GbE, PCI Express, SRIO, and PCI/PCI-X interfaces, enabling multi-port routing, switching, and acceleration platforms.
Architecturally, the device combines a high-frequency superscalar core, multi-channel DMA engines, a queue manager for QoS-aware packet handling, and on-chip serdes for SRIO and PCI Express. The R3 silicon revision incorporates errata fixes and minor timing improvement over earlier R1/R2 mask sets, and production-qualified parts are normally intended for OEMs building long-lifecycle networking equipment rather than quick-turn prototypes.
Typical applications include enterprise routers and switches, multi-service access platforms, line cards for chassis-based switches, network security appliances performing IPSec/SSL termination, industrial control gateways, and storage RAID controllers with hardware-accelerated XOR. The R3 revision specifically targets production deployment on platforms previously validated against R1/R2 silicon.
Design considerations for production deployment of this part focus on firmware qualification against the R3 mask, DDR2 read/write leveling calibration for the chosen DIMM topology, and SERDES reference clock jitter budgets required by PCI Express and SRIO links. Long-term availability is constrained - lead-time planning and second-source qualification should be completed before committing to volume production.

主な用途
SCN8548EVTAUJD の用途: 6 件s: Enterprise Router Line Card, Multi-Service Switch / Chassis Line Card, IPSec / SSL VPN Security Appliance, Industrial Control Gateway / Edge Router, Storage RAID Controller with HW XOR, Wireless Base Station Control Plane.
Enterprise Router Line Card
The SCN8548EVTAUJD fits enterprise router line cards because its 1333 MHz e500v2 core and GbE + PCI Express + SRIO combination deliver wire-speed forwarding for Gigabit routing engines. According to the NXP MPC8548 product description, the SEC 3.x engine accelerates IPSec tunnel setup and bulk cipher, allowing the same SoC to terminate VPN traffic without off-loading to a secondary crypto ASIC. Designers place the SoC adjacent to a DDR2 ECC DIMM socket, SERDES reference clock, and a regulator suite providing 1.0 V core and 1.5 V/1.8 V DDR2 supplies per the hardware specifications.
おすすめ
Multi-Service Switch / Chassis Line Card
The SCN8548EVTAUJD suits multi-service switch line cards that require a mix of GbE, PCI-X, and PCI Express connectivity. The R3 silicon revision integrates RapidIO 1.x for backplane communication between line cards, while the local-bus controller connects to legacy ASICs and switch fabrics already deployed in installed chassis. With 0 to 105 C temperature support, the part handles densely packed line cards where ambient intake air is well above 60 C. Designers typically pair it with a dedicated DDR2 ECC DRAM to absorb micro-bursts from QoS queues.
おすすめ
IPSec / SSL VPN Security Appliance
Security appliances depend on the SCN8548EVTAUJD for IPSec and SSL termination because the SEC 3.x crypto engine accelerates AES, 3DES, RSA, and ECC operations at line rate. The 1333 MHz e500v2 core runs control-plane logic and policy management, while the SEC engine handles bulk data-path encryption, freeing the core for routing and session lookup. The DDR2 ECC controller sustains VPN packet reordering queues without silent DRAM errors, and the integrated GbE MACs connect to multi-port NIC ASICs over PCI Express.
おすすめ
Industrial Control Gateway / Edge Router
Industrial edge gateways benefit from the SCN8548EVTAUJD's combination of GbE, PCI Express, and the industrial temperature grade of 0 to 105 C. Designers use the integrated local bus to attach legacy industrial field buses (Profibus, CAN gateways) and expose them as TCP/IP services to supervisory control. The rugged temperature range and R3 silicon errata fixes make the part reliable for unattended remote deployments where on-site service is costly.
おすすめ
Storage RAID Controller with HW XOR
Storage RAID controllers leverage the SCN8548EVTAUJD's DMA engine, DDR2 ECC, and PCI Express interface to perform RAID 5/6 parity calculations and host off-load operations. With the 1333 MHz e500v2 core and on-chip SERDES, the SoC can drive multiple SAS/SATA channels bridged behind PCI Express from a single chip. ECC memory prevents silent corruption during long rebuild operations, and the 0 to 105 C thermal envelope allows passive cooling in dense storage enclosures.
おすすめ
Wireless Base Station Control Plane
The SCN8548EVTAUJD fits wireless base station control-plane cards where deterministic real-time processing and high-bandwidth backhaul are mandatory. The R3 silicon revision supports Serial RapidIO 1.x for backplane digital radio connection and PCI Express for CPRI link off-loading. The 1333 MHz e500v2 core has enough headroom for Open Transport and OAM protocol stacks, while the SEC engine accelerates subscriber authentication. ECC DDR2 provides reliability for 24/7 cellular base-station operation.

主な差別化要因
- Identical silicon offered with both legacy Freescale SCN prefix and modern NXP MPC prefix （vs MPC8548EVTAUJD)
- Drop-in alternative lowers design risk versus newer QorIQ devices （vs NXP P2020 QorIQ)
- Dedicated SEC 3.x crypto engine without external ASIC （vs MPC8569 (lower-tier sibling))
設計ノート
Estimated: the MPC8548 family uses a 783-ball FC-PBGA on a 1.0 mm or 0.8 mm pitch. Decoupling must place 1 uF and 0.1 uF ceramic capacitors within 5 mm of every power pin; do not share vias between adjacent balls. DDR2 data byte lanes must be length-matched within the tolerance stated in the NXP hardware specifications document, and VTT termination must be placed near the DRAM rather than at the SoC.
Estimated: SERDES reference clock jitter for PCI Express and Serial RapidIO must be held below the value specified in the MPC8548 hardware specifications document; a low-jitter clock buffer is mandatory when more than one SERDES lane is enabled. Route SERDES pairs on the top layer or buried microstrip with continuous reference plane, no splits, and length matched within 0.127 mm. Avoid routing any other high-speed signal across the SERDES ground keepout.
Estimated: at the maximum 1333 MHz core frequency with full PCI Express and SRIO activity, the SCN8548EVTAUJD can dissipate 5 W to 8 W depending on workload. The 0 to 105 C ambient specification assumes a thermally adequate substrate; in chassis line-card applications a heatsink with at least 1 C/W thermal resistance plus 200 LFM airflow is recommended. Validate junction temperature with on-die thermal sensor rather than external diode for accuracy.
Never confuse the SCN (Freescale-prefixed distribution inventory) with the MPC ordering part number - both ship identical silicon but the SCN prefix is used by Rochester Electronics for legacy support. Drop-in for production builds should be sourced as MPC8548EVTAUJD or equivalent R3-revision variant. Always verify against the latest NXP errata document for the R3 mask before committing to production firmware.
Estimated: the SCN8548EVTAUJD requires at least three supply rails - core (typically 1.0 V), I/O (typically 1.8 V or 2.5 V) and DDR2 supply (1.8 V). Power-on reset sequencing per the NXP hardware specifications document mandates core rail valid before I/O, and a common reset supervisor is required to hold RESET until all rails are stable. Soft-start ramp rate should not exceed the maximum specified or POR detection can fail intermittently.
