MPC8241LVR166D - 166MHz Integrated Host Processor | NXP
The NXP MPC8241LVR166D is a 32-bit Power Architecture integrated host processor operating at 166 MHz, combining an MPC603e PowerPC core microprocessor with a PCI bridge in a 357-ball BGA (HiTCE) package. The device integrates a PowerPC processor core, a PCI bridge, memory controller, DMA engine and peripheral interfaces on a single die, collapsing what used to be five discrete ICs into one and shrinking board area, BOM cost and power budget. The 'L' suffix denotes a low-voltage 1.8 V core supply variant and the 'VR' industrial temperature range, with '166' marking the 166 MHz core frequency and 'D' indicating revision D silicon.
An integrated host processor is a category of system-on-chip (SoC) device that combines a microprocessor core with platform glue logic (memory controller, peripheral bridges, DMA, interrupts and I/O). In the broader taxonomy it sits between a standalone microprocessor (which would require an external north bridge / south bridge chipset) and a full application processor (which typically adds graphics, video and run-time memory management). The MPC8241 targets embedded computing applications where deterministic performance, low power and a compact footprint matter more than raw compute density.
Key features include a 64-bit PowerPC 603e core with 16 KB instruction and 16 KB data L1 caches, an integrated 32-bit/64-bit PCI interface operating at up to 66 MHz, a high-performance SDRAM memory controller supporting up to 1 GB of addressable memory, two I2C and two UART ports, and a DMA engine with four channels. The 357-BGA HiTCE plastic package gives a thermal resistance typical of high-performance embedded BGA parts in this class. Industrial temperature grade -40C to +105C is supported by the VR suffix, making the part usable in non-controlled environments.
The architecture is built around a 60x-compatible processor local bus (PLB), an internal peripheral bus and a dedicated PCI bus that maps directly to the external PCI pins. An integrated memory controller handles SDRAM with ECC, and a multi-channel DMA engine offloads block moves from the core. The single-chip integration removes external chipset skew, simplifies timing closure on the board, and reduces typical system power by eliminating multiple I/O buffers.
Typical applications include industrial control and automation, RAID storage controllers, networking line cards, telecom base-station control, imaging and printing equipment, and point-of-sale terminals. The integrated PCI bridge particularly suits designs that need to attach PCI peripherals without an extra chip.
When designing with the MPC8241LVR166D, plan for at least four PCB layers to route the 357-ball BGA cleanly, place 100 nF decoupling within 5 mm of every supply pin, and verify DDR/SDRAM trace matching against the integrated memory controller reference design. Production designs should include JTAG on the boundary-scan chain for bring-up.
