MPC8241LZQ266D - PowerPC 603e MPU, 266 MHz, 357-PBGA | NXP
MPN: MPC8241LZQ266D ⚠ Lần mua cuốiMPC8241LZQ266D Tóm tắt
An Integrated Host Processor (also called an integrated communications processor or PowerQUICC II) is a category of system-on-chip that merges a CPU core, a system / peripheral bus bridge, and memory-control logic into one silicon die. The hypernym hierarchy runs: microprocessor -> MPU -> integrated host processor -> PowerQUICC II -> communications SoC. The MPC8241 belongs to the MPC82xx (PowerQUICC II) family, originally introduced by Motorola, transferred to Freescale Semiconductor, and now maintained by NXP Semiconductors.
Key features include a 266 MHz PowerPC 603e core delivering 266 MIPS of integer performance, a 64-bit SDRAM memory controller with ECC support, a 32-bit PCI v2.2-compatible bridge operating up to 66 MHz, and an integrated DMA engine with four channels. The device supports both 60x and local-bus peripherals, provides two I2C controllers, and integrates a 32-bit address / 64-bit data SDRAM interface.
Architecturally the part uses a 0.25 micrometer CMOS process, separate core and I/O voltage domains (1.8 V core, 3.3 V I/O) to reduce power dissipation, and a Harvard-style split I/D cache. The on-chip PCI bridge eliminates the need for a discrete PCI controller chip, allowing engineers to connect standard PCI peripherals directly to the host.
Typical applications include industrial routers and network gateways, RAID and storage controllers, embedded single-board computers, telecom line cards, printing and imaging controllers, and PCI-based peripheral expansion boards. The combination of PowerPC processing, integrated PCI, and SDRAM control suits mid-range embedded designs that need deterministic real-time behaviour.
When designing with this part, ensure the dual-rail supply sequence matches the datasheet (typically core first, then I/O). The 25 x 25 mm PBGA requires a 1.27 mm pitch PCB land pattern and at least six PCB layers for the power/ground and SDRAM-trace routing. Decoupling follows the PowerQUICC II reference design, with one bulk cap per voltage pin plus high-frequency ceramics.

Ứng dụng tiêu biểu
MPC8241LZQ266D phù hợp cho 6 Áp dụngs: Industrial Router / Network Gateway, RAID / Storage Controller, Telecom Line Card / Embedded SBC, Printing and Imaging Controller, PCI Expansion / Peripheral Card, Legacy Embedded System Maintenance.
Industrial Router / Network Gateway
The MPC8241LZQ266D's 266 MHz PowerPC 603e core and integrated PCI bridge make it a fit for industrial router designs where deterministic packet handling and PCI-attached NICs are required. The on-chip 64-bit SDRAM controller with ECC supports large routing tables without external memory glue logic. The 0 to 105 C operating temperature covers factory-floor cabinets, and the dual 1.8 V core / 3.3 V I/O supply simplifies integration with standard PHY and magnetics. Compared with a discrete CPU-plus-PCI-controller solution, this single-chip integration reduces board area and EMI.
Được đề xuất
RAID / Storage Controller
The MPC8241LZQ266D's 4-channel DMA engine and 64-bit SDRAM controller make it suitable for RAID controller cards where high-throughput data movement and ECC-protected buffer storage are essential. The PCI v2.2 bridge running at 66 MHz provides a standard host-side interface for desktop or server RAID products. Hardware ECC on the SDRAM interface protects against soft errors in long-running storage applications. The 266 MIPS integer performance is adequate for command queuing and XOR-acceleration firmware.
Được đề xuất
Telecom Line Card / Embedded SBC
The MPC8241LZQ266D's combination of PowerPC processing and PCI expansion suits telecom line cards and embedded single-board computers that need to drive PCI-based mezzanine cards. The 60x and local bus interfaces allow connection to legacy or custom peripherals alongside the PCI domain. The 1.8 V / 3.3 V split rail reduces power dissipation compared with older 5 V designs, important for sealed enclosures. The integrated peripherals (two I2C controllers, four DMA channels) shrink the BOM count for cost-sensitive SBCs.
Được đề xuất
Printing and Imaging Controller
Printer and imaging controller designs benefit from the MPC8241LZQ266D's deterministic real-time performance and rich DMA and bus connectivity. The PCI bridge connects to scanner engines and image-processing accelerators, while the SDRAM controller buffers large page images at high bandwidth. The PowerPC 603e's integer performance handles raster image processor (RIP) workloads efficiently, and the integrated DMA offloads page-description-language parsing. The 357-PBGA footprint supports compact PCI-card form factors used in print engines.
Được đề xuất
PCI Expansion / Peripheral Card
The MPC8241LZQ266D can act as the host CPU on PCI expansion cards such as data-acquisition boards, software-defined-radio front-ends, or industrial I/O cards. The PCI v2.2 bridge supports both initiator and target roles, allowing custom peripherals to communicate with the host system. The local bus connects to FPGA or ASIC companion devices, and the 32-bit/64-bit SDRAM interface provides high-bandwidth local memory. This makes the part a flexible platform for PCI-based proprietary I/O products.
Được đề xuất
Legacy Embedded System Maintenance
The MPC8241LZQ266D is widely used to maintain deployed legacy embedded systems where the PowerPC firmware cannot be easily ported to a newer architecture. Existing real-time operating systems (VxWorks, Linux 2.6 PowerPC, etc.) and toolchains remain available through NXP's long-term support channels. The integrated peripherals match the original reference design, allowing direct board-replacement without firmware changes. For new designs, however, migrating to QorIQ Layerscape or ARM Cortex-A SoCs is recommended.

Ghi chú thiết kế
The MPC8241LZQ266D requires two independent rails - 1.8 V for the core and 3.3 V for I/O - sequenced core-first per the datasheet. Place one bulk tantalum or polymer cap (47 to 100 uF) per rail close to the BGA, plus 0.1 uF and 0.01 uF ceramics on each power pin pair. The estimated core current at 266 MHz is roughly 500 to 700 mA; the I/O rail draws additional current proportional to bus activity.
The 357-PBGA at 25 x 25 mm with 1.27 mm pitch needs at least a six-layer PCB to route the 64-bit SDRAM data bus, the 32-bit PCI bus, and the 60x bus without excessive vias. Use microvia or laser-drilled vias if the board house supports them, and keep the SDRAM trace lengths matched within the datasheet's stated skew. The exposed thermal pad (if present in the specific BGA variant) should be soldered to a continuous ground plane to aid heat spreading.
Do not assume the MPC8241LZQ266D is RoHS-compliant - the verified distributor data shows 'Contains Lead' for this suffix. Do not substitute the MPC8241TVR200D without verifying the ball-map, because the package suffix differs. Finally, confirm DDR/SDRAM compatibility - the MPC8241 supports SDR SDRAM with specific row/column addressing rules, not DDR memory; mixing the two will not work.
Thông tin tuân thủ
Lead-free status is 'No' / 'Contains Lead' per NXP product page per verified distributor data. RoHS non-compliant. AEC-Q100 not applicable - this is an industrial/telecom MPU, not an automotive-grade part.
