MPC8245LZU350D 개요
What is an integrated host processor? An integrated host processor is a system-on-chip that merges a general-purpose CPU core with peripheral controllers (PCI, memory, I/O) onto a single die, eliminating the need for a discrete north bridge. Within the taxonomy, the MPC8245LZU350D sits at: integrated host processor -> embedded microprocessor -> MPU -> semiconductor. It belongs to NXP's MPC82xx family, designed to bridge PowerPC performance with peripheral integration for networking and storage.
Key features of the MPC8245LZU350D include a 350 MHz PowerPC 603e core, integrated PCI bridge supporting up to 66 MHz PCI operation, SDRAM memory controller, 32-bit data bus architecture, and 0.25 um CMOS process technology. Operating voltage is centered at 3.3V with multiple power rails. The integrated design reduces board complexity, BOM cost, and power consumption compared to discrete CPU-plus-chipset solutions.
Technically, the device uses a superscalar PowerPC 603e core with separate 16 KB instruction and 16 KB data L1 caches, hardware table-walk for MMU translations, and dedicated SDRAM controller with ECC support. The internal PCI bridge arbitrates transactions between the processor core and PCI peripherals, simplifying PCB routing and reducing latency for I/O-bound workloads.
Typical applications include networking infrastructure (routers, switches, access controllers), storage controllers (RAID, NAS), printer/imaging controllers, industrial automation controllers, and embedded telecom equipment. Its balance of compute throughput with peripheral integration makes it ideal for mid-range systems previously requiring separate host bridges.
When designing with this part, ensure the 3.3V core and I/O rails are properly decoupled, the JTAG boundary-scan chain is correctly terminated, and the TBGA substrate thermal vias provide adequate heat removal. Designers should verify that boot ROM and reset configuration straps are correctly pulled to select CPU-to-memory ratio and boot source.
This page synthesizes distributor pricing, datasheet specifications, drop-in compatible same-package alternatives, and practical design considerations not found in the manufacturer datasheet alone, giving procurement and design engineers a single source for evaluating the MPC8245LZU350D in long-lifecycle embedded designs.

설계 노트
The 352-TBGA package requires thermal vias under the die and adequate copper pours on inner PCB layers to dissipate the 3-5W typical power dissipation. At maximum ambient of 105C, designers must verify junction temperature stays below the rated maximum using the package theta_JA from the datasheet. Add a heatsink only if natural convection is insufficient for the enclosure.
Route the 32-bit data bus with matched impedance (50 ohm typical) and keep trace lengths matched within +/- 100 mils to avoid setup/hold violations on the SDRAM interface. Place SDRAM chips adjacent to the MPC8245LZU350D with short traces; add series termination resistors near the driver if reflections appear on the SDRAM clock. The PCI bus also requires 50-65 ohm impedance and length matching for 66 MHz operation.
Do not confuse the 'ZU' (TBGA 35x35) suffix with other MPC8245 package codes such as 'TZU' or 'ZU' from related families. Verify boot configuration resistor strapping against the datasheet's reset configuration chapter, as incorrect settings can cause silent boot failures. Confirm JTAG chain integrity during prototype bring-up because BGA rework is expensive if boundary-scan is broken.
Use separate decoupling capacitor banks for the core (3.3V), SDRAM interface, and PCI I/O rails. Place 0.1 uF ceramic capacitors within 50 mils of each supply pin and add bulk tantalum or polymer capacitors (10-100 uF) near the package. Power sequencing between rails may be required per the datasheet; check the power-up chapter before finalizing the regulator topology.
