MPC8315VRADDA

Overview

The MPC8315VRADDA is a PowerQUICC II Pro System-on-Chip based on the PowerPC e300c3 core. It operates at a maximum clock frequency of 266 MHz with a 32-bit data bus width. The device integrates support for DDR and DDR2 SDRAM memory controllers, along with L1 instruction and data caches of 16 kB each. Connectivity features include two Gigabit Ethernet ports, two SATA interfaces, one USB 2.0 port with PHY, PCI/PCIe, TDM, I2C, SPI, and DUART. It utilizes a 620-pin TEPBGAII package and supports I/O voltages of 1.8V, 2.5V, and 3.3V.

Feature Summary

• Integrates a high-performance PowerPC e300c3 processor core optimized for embedded applications.
• Provides comprehensive connectivity through dual Gigabit Ethernet, SATA, and PCIe interfaces.
• Supports flexible memory configurations with integrated DDR and DDR2 controllers.
• Includes hardware encryption capabilities for secure data processing.

Applications

• Networking switches and line cards
• Wireless LAN access points
• Network Access Servers (NAS)
• VPN routers

Procurement Notes

Verify the specific revision level required for your design, as the MPC8315E family includes multiple variants. Confirm that the 620-pin BGA footprint matches your PCB layout constraints. Ensure power supply designs accommodate the specified 1.8V, 2.5V, and 3.3V rails. Check for end-of-life status or obsolescence notices from NXP Semiconductors before finalizing procurement plans.

Selection Notes

Select this component when a balance of moderate CPU performance and extensive peripheral integration is required. It is suitable for applications needing multiple high-speed serial interfaces like SATA and GbE without external bridge chips. Consider thermal management requirements due to the dense BGA packaging. Compare against higher-frequency models if processing speed is the primary constraint.

Part Context

This part belongs to the Freescale/NXP MPC8315E PowerQUICC II Pro family. These processors are designed for cost-effective, low-power networking and industrial control applications. The MPC8315VRADDA specifically denotes the 266 MHz speed bin within the VRAGDA/VRADDA package variations. It extends the PowerQUICC family by adding faster interfaces and enhanced functionality compared to earlier generations.

Replacement Considerations

Direct substitutes within the same family include the MPC8315VRAGDA, which offers a higher clock speed of 400 MHz but shares the same package and pinout. Other compatible parts in the MPC83xx series may require software adaptation due to differences in peripheral counts or clock speeds. Verify electrical compatibility before swapping.
