NXP Semiconductors MPC8245LVV333D

Overview

MPC8245LVV333D from Freescale Semiconductor is a 32-bit PowerPC™ MPC603e-based integrated processor combining a superscalar CPU core with PCI bridge, memory controller, DUART, DMA, and I2C peripherals in a single TBGA package. It operates at up to 333 MHz CPU frequency, supports 66 MHz PCI bus and 133 MHz SDRAM interface, and targets embedded control systems requiring high integration and deterministic real-time response.

For engineers reviewing the MPC8245LVV333D datasheet, MPC8245LVV333D pinout, MPC8245LVV333D application, or MPC8245LVV333D equivalent, key selection criteria include its 333 MHz CPU speed grade, 1.9–2.1 V core supply requirement, 352-pin TBGA package, PCI 2.2 compliance, and dual UART support for industrial communication gateways.

Technical Context

The MPC8245LVV333D integrates a full-featured MPC603e core (16-Kbyte instruction cache, 16-Kbyte data cache, FPU, MMU) with tightly coupled peripheral logic including a 32-bit PCI interface (66 MHz, 5.0-V tolerant), SDRAM controller (up to 2 GB, 133 MHz), and dual UARTs. Its dual-PLL architecture enables independent clocking of CPU (333 MHz) and peripheral logic (66 MHz PCI, 133 MHz SDRAM).

It implements a decoupled 32-bit address / 64-bit data peripheral logic bus with store-gathering, memory coherency, and programmable timing for SDRAM and ROM/Flash. The device supports both PCI host and agent modes, big/little-endian operation, and hardware-enforced coherency for cache-synchronized multi-master systems.

FAQ

What is the maximum supported SDRAM capacity for MPC8245LVV333D?

The MPC8245LVV333D supports up to 2 Gbytes of SDRAM memory across one to eight banks using 16-, 64-, 128-, 256-, or 512-Mbit devices. This capacity is enabled by its 32-bit address bus and programmable SDRAM timing controller, allowing flexible memory configurations for buffering-intensive applications like packet inspection or image processing. The MPC8245LVV333D achieves this with a 133 MHz memory bus and optional ECC protection.

Does MPC8245LVV333D support both big-endian and little-endian operation?

Yes, the MPC8245LVV333D supports selectable big-endian or little-endian operation through configuration registers accessible via PCI or internal bus. This flexibility allows the MPC8245LVV333D to interface seamlessly with legacy big-endian peripherals (e.g., older telecom ASICs) while maintaining compatibility with modern little-endian software stacks and operating systems such as Linux.

What are the power management modes available on MPC8245LVV333D?

The MPC8245LVV333D implements three dynamic power management modes: Doze (1.4 W typical), Nap (0.5 W typical), and Sleep (0.3 W typical). These modes progressively disable CPU execution units, caches, and peripheral clocks while retaining register state and wake-up capability via IRQ or timer events. The MPC8245LVV333D uses these modes to meet stringent thermal budgets in fanless enclosures without compromising system responsiveness.

Can MPC8245LVV333D operate as a PCI bus master and slave simultaneously?

Yes, the MPC8245LVV333D can function as both a PCI bus master and slave (agent) concurrently. Its PCI interface supports master transactions (initiating memory/I/O reads/writes) and slave responses (servicing configuration space accesses or memory-mapped I/O from other PCI masters). This dual-role capability makes the MPC8245LVV333D ideal for bridging roles in multi-processor systems or acting as a central hub in PCI-based backplanes.

What is the purpose of the PLL_CFG[0:4] signals on MPC8245LVV333D?

The PLL_CFG[0:4] signals on the MPC8245LVV333D configure the CPU and peripheral logic PLL multipliers/dividers at reset, determining final operating frequencies for the 333 MHz CPU core, 66 MHz PCI bus, and 133 MHz SDRAM interface. These five pins must be driven during reset and held stable for at least 25 clock cycles after HRST_CTRL/HRST_CPU deassertion to latch valid settings - a critical step for reliable MPC8245LVV333D initialization.
