部品番号: MPC603RRX266LC ✗ 生産終了MPC603RRX266LC 概要
What is a PowerPC MPU? A PowerPC microprocessor (MPU) is a 32-bit or 64-bit RISC processor core derived from the AIM (Apple-IBM-Motorola) PowerPC architecture. In the embedded hierarchy, a PowerPC MPU sits above microcontrollers (MCUs) in performance and integration: MPU -> embedded processor -> SoC -> computing platform. The 603e family specifically targets cost- and power-sensitive embedded designs where higher performance than an MCU is required but full desktop CPU features are unnecessary.
Key features include a 266 MHz core clock, 32-bit data and address paths, on-chip L1 instruction and data caches, a separate integer and floating-point unit, and a 2.5 V core supply. The FCCBGA package provides high-density interconnect for compact embedded modules and operates over industrial temperature ranges. The device also includes a JTAG IEEE 1149.1 boundary-scan test interface and supports multiprocessor configurations via dedicated address and data bus arbitration.
Architecturally, the MPC603e implements a four-stage pipeline with out-of-order execution and dynamic branch prediction, delivering roughly 3.5 SPECint95 per MHz. Its low-power features include doze, nap, and sleep modes that gate clocks to unused functional units. Compared to the original 603, the 603e added hardware assist for graphics and improved L2 cache support.
Typical applications include network routers and switches, industrial control systems, aerospace flight computers, telecom base stations, and legacy PowerPC embedded designs. The 266 MHz speed grade targets moderate-performance workloads requiring deterministic real-time behavior. Per Motorola PID7t-603e documentation, this part also carries extended-temperature grade for industrial use.
When designing with this part, provide a 2.5 V regulated core supply, a 3.3 V I/O supply, and proper PLL power filtering. Note that the MPC603RRX266LC is marked obsolete on most distributor pages; long-term designs should evaluate modern PowerQUICC or QorIQ replacements or source from authorized aftermarket channels.
This page synthesizes distributor stock data, parametric comparisons against related MPC603e speed grades, and design notes that extend beyond the manufacturer datasheet to support both legacy maintenance and new design feasibility checks.

主な用途
MPC603RRX266LC の用途: 6 件s: Network Router Control Plane, Industrial Process Controller, Aerospace Flight Computer, Telecom Base Station Controller, Storage Area Network Controller, Medical Imaging Pre-processor.
Network Router Control Plane
The MPC603RRX266LC's 266 MHz PowerPC 603e core delivers enough processing throughput for routing-table lookup and packet-classification workloads in legacy mid-range routers. Its 32-bit data path and on-chip branch target buffer enable deterministic forwarding performance, while the 0.29 micron process keeps active power manageable for fanless chassis designs. The 2.5 V core / 3.3 V I/O split allows integration with standard telecom ASICs without extra level shifters, and the 255-FCCBGA package supports high-density backplane routing on compact line cards.
おすすめ
Industrial Process Controller
At 266 MHz with hardware-assisted floating point, the MPC603RRX266LC executes PID loops, motion-control sequences, and SCADA protocol stacks on factory-floor controllers. The FCCBGA ceramic package supports industrial temperature ranges and the vibration profiles typical of machine-mount enclosures. The PowerPC 603e's four-stage pipeline with branch prediction maintains low interrupt latency critical for deterministic control, while its doze/nap/sleep modes reduce power consumption during idle PLC scan cycles.
おすすめ
Aerospace Flight Computer
The MPC603RRX266LC's FCCBGA ceramic package and industrial temperature grading make it suitable for aerospace avionics subsystems where plastic-packaged MPUs are unacceptable. The PowerPC architecture is widely supported by RTOS vendors (VxWorks, Integrity, LynxOS) with DO-178C certification evidence, easing qualification of flight-control code. The on-chip floating-point unit accelerates inertial-navigation math, while JTAG 1149.1 boundary scan supports board-level test on flight hardware.
おすすめ
Telecom Base Station Controller
Legacy GSM/UMTS base-station controllers deployed the MPC603RRX266LC for Layer-2 processing, encryption, and backhaul aggregation. The processor's hardware cache-coherency protocol supports symmetric multiprocessing with a second 603e, doubling throughput for high-density cell sites. The 3.3 V I/O compatibility simplifies connection to legacy telecom ASICs, and the FCCBGA substrate dissipates HEAT effectively in sealed outdoor enclosures.
おすすめ
Storage Area Network Controller
The MPC603RRX266LC's 32-bit data path and L1 caches make it a fit for RAID-engine controller boards where it offloads command parsing and XOR compute from the host CPU. The PowerPC 603e's load/store architecture with write-back caches accelerates sequential and random I/O workloads, while the FCCBGA package supports the dense multi-channel layout of 8-16 port SATA/SAS controllers. The 2.5 V core also simplifies integration with modern ASICs designed for similar low-voltage rails.
おすすめ
Medical Imaging Pre-processor
In ultrasound and patient-monitoring pre-processor boards, the MPC603RRX266LC executes DSP-style preprocessing of sampled signals before forwarding to host CPUs. Its hardware floating-point unit accelerates FFT and convolution kernels, while deterministic interrupt response preserves the timing margins required for real-time signal acquisition. The FCCBGA ceramic package meets the long-term reliability expectations of medical device OEMs, and the 266 MHz speed grade is well-matched to mid-tier ultrasound channels.

設計ノート
Estimated: at 266 MHz with all units active, the MPC603e core draws roughly 4 W from the 2.5 V rail; in doze mode the power drops by ~80%. Provide a switching regulator with at least 5 A capacity on the 2.5 V core rail and at least 2 A on the 3.3 V I/O rail. The PLL supply (AVDD) must be derived from the 2.5 V rail through a ferrite bead and decoupling capacitor per the Motorola PID7t-603e reference schematic to minimize jitter.
The 255-FCCBGA package has a theta-JA of approximately 12 C/W with adequate forced airflow (200 LFM). At full-load 4 W dissipation, junction temperature rises 48 C above ambient. Provide 200 LFM minimum airflow or a heatsink attached via thermal interface material for industrial chassis with no airflow. Use temperature sensors on the package top to monitor junction temperature during characterization.
The 255-FCCBGA uses a 1.27 mm ball pitch and requires ENIG surface finish for reliable assembly. Per IPC-7351, escape-routing the inner rows of the BGA demands microvia or HDI PCB technology with stacked vias. Place decoupling capacitors on the bottom side of the board directly under the BGA footprint, and dedicate at least 4 PCB layers to solid power and ground planes for return-path integrity.
The MPC603e 603e processor bus runs at 66 MHz synchronous to the CPU core. Match bus trace lengths to within 1.5 inches across address and data groups, and use 50 ohm controlled impedance. Series-stopp resistors may be required on heavily-loaded address lines to dampen reflections; consult the PID7t-603e hardware specification section on bus design for timing budgets.
