Core and peripheral fit for a control-plane SoC
The MPC8315EVRADDA is a PowerQUICC II Pro processor built around a single PowerPC e300c3 core running at 266 MHz — a 32-bit architecture with a full integer and floating-point unit, aimed at control-plane processing in networking, industrial, and storage equipment. It integrates a USB 2.0 port with on-chip PHY, two SATA 3 Gbps channels, and dual Gigabit Ethernet MACs with 10/100/1000 Mbps support — enough serial bandwidth to serve as a bridge between legacy parallel buses and modern serial-attached storage or network interfaces. The memory controller handles both DDR and DDR2 SDRAM, giving the board designer flexibility to use lower-cost DDR2 while maintaining a migration path from older DDR-based designs.
Security offload and peripheral mix
A dedicated SEC 3.3 security engine handles cryptographic acceleration and includes a random number generator — this offloads the main core from TLS/IPsec packet processing, critical for secure gateway and VPN appliance designs. Additional interfaces include DUART, I²C, PCI, SPI, and TDM, covering most control and debug connections needed in a baseboard management controller or line-card processor.
Housed in a 620-ball HBGA with an exposed thermal pad (29 mm × 29 mm), the package is designed for surface-mount reflow with a central ground slug that must be soldered to the PCB thermal land for adequate heat transfer. The operating temperature range is 0 °C to 105 °C (ambient), which covers most indoor telecom and industrial enclosures but not extended automotive or outdoor unventilated cabinets.
