Product details
Overview
MPC8245LVV350D from Freescale Semiconductor is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, SDRAM memory controller, dual UARTs, DMA, I²C, and interrupt controllers in a single TBGA package. It operates at up to 350 MHz CPU frequency, supports 66 MHz PCI bus, and delivers embedded system-level integration for telecom infrastructure, industrial control, and network edge devices.
For engineers reviewing the MPC8245LVV350D datasheet, MPC8245LVV350D pinout, MPC8245LVV350D application, or MPC8245LVV350D equivalent, key selection considerations include its 350 MHz CPU speed, 1.9–2.2 V core supply requirement, 352-pin TBGA package, PCI 2.2 compliance, and support for up to 2 GB SDRAM - all critical for legacy Power Architecture® system upgrades and long-lifecycle industrial designs.
Technical Context
The MPC8245LVV350D implements a dual-PLL architecture: one PLL drives the 350 MHz MPC603e core (VDD/AVDD = 2.0–2.1 V ±100 mV), while a separate peripheral logic PLL generates synchronized clocks for PCI (66 MHz) and SDRAM interfaces. Its internal 64-bit peripheral logic bus decouples address and data paths, enabling pipelined accesses and store-gathering for PCI writes.
It integrates full memory coherency, ECC-capable data path, programmable output drivers (DRV_STD_MEM, DRV_PCI), and dynamic power management with nap/doze/sleep modes. The device supports both big- and little-endian operation, selectable hardware-enforced coherency, and dual-address-cycle (DAC) 64-bit PCI addressing in master mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar integrated processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8241LVV300D | Same architecture, lower max CPU frequency (300 MHz); VDD/AVDD = 1.8/1.9/2.0 V ±100 mV; identical 352-TBGA package | Suitable for cost-sensitive designs where 350 MHz headroom is unnecessary; lower power draw in nap/sleep modes | Select when thermal budget or supply voltage stability constraints preclude 2.0/2.1 V operation required by MPC8245LVV350D |
| MPC8247ZQH333D | Enhanced variant with integrated USB 1.1 host controller and additional GPIO; same 350 MHz CPU but different pinout (376-pin PBGA) | Required for designs needing native USB peripheral connectivity; incompatible PCB layout due to package and pin assignment changes | Choose only if USB host capability is mandatory and board redesign is feasible; not a drop-in replacement |
Compared with MPC8245LVV350D, MPC8241LVV300D offers identical functionality at reduced speed and voltage, while MPC8247ZQH333D adds USB but sacrifices pin compatibility - making the former a true voltage/speed downgrade option and the latter a feature-upgrade requiring layout revision.

FAQ
What is the maximum supported SDRAM capacity for MPC8245LVV350D?
The MPC8245LVV350D supports up to 2 GB of SDRAM memory across one to eight banks using 16-, 64-, 128-, 256-, or 512-Mbit devices. This capacity is achieved with a 32- or 64-bit wide memory data bus and programmable timing parameters that accommodate commercial and industrial-grade SDRAM components under the specified operating conditions.
Does MPC8245LVV350D support both big-endian and little-endian operation?
Yes, the MPC8245LVV350D supports selectable big-endian or little-endian operation via configuration bits in the HID0 register. This flexibility allows the MPC8245LVV350D to interface seamlessly with legacy big-endian PowerPC firmware or newer little-endian Linux BSPs without hardware modification.
What are the power supply sequencing requirements for MPC8245LVV350D?
MPC8245LVV350D requires strict supply voltage sequencing: VDD/AVDD/AVDD2 must stabilize before OVDD/GVDD, with LVDD applied last. Per Figure 2, OVDD/GVDD ramp must begin only after VDD reaches 1.4 V, and LVDD (5 V) must not be applied until OVDD/GVDD are fully stable. Violating this sequence risks latch-up or permanent damage.
Can MPC8245LVV350D operate as a PCI bus master and slave simultaneously?
Yes, the MPC8245LVV350D supports both PCI host (master) and agent (slave) modes concurrently. In host mode, it initiates PCI transactions to peripherals; in agent mode, it responds to configuration reads/writes and memory-mapped I/O from another PCI host - enabled via configuration space register settings and ATU inbound/outbound window programming.
Is MPC8245LVV350D pin-compatible with other MPC82xx variants?
No, MPC8245LVV350D is not pin-compatible with MPC8241 or MPC8247 despite sharing the 352-pin TBGA footprint. Pin assignments for DDR/SDRAM signals, PCI control lines, and peripheral logic buses differ significantly across the MPC82xx family - requiring unique PCB layouts for each variant, even within the same package type.
