MPC8314CVRAFDA

Overview

The MPC8314CVRAFDA is a PowerQUICC II Pro System-on-Chip (SoC) microprocessor manufactured by Freescale Semiconductor. It integrates an e300c3 core operating at up to 400 MHz with 16-Kbyte instruction and data caches, floating-point support, and MMUs. The device features dual enhanced three-speed Ethernet controllers (eTSECs), DDR1/DDR2 memory controller, Security Engine 3.3, USB 2.0, PCI Express x1, and PCI interfaces. It utilizes a 620-ball HBGA package and operates within a temperature range of -40°C to +105°C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and voltage requirements. Confirm that the component status is acceptable for your design lifecycle, as this part may be subject to obsolescence notices. Ensure all power supply sequencing adheres strictly to the electrical characteristics defined in the datasheet to prevent device damage.

Selection Notes

Select this processor when a highly integrated SoC with robust networking capabilities and hardware security acceleration is required. It is suitable for designs needing backward software compatibility with previous PowerQUICC generations. Consider the thermal dissipation characteristics and power management states if low-power standby modes are critical for the application environment.

Part Context

This component belongs to the MPC8314E PowerQUICC II Pro family, which extends the Power Architecture portfolio with higher CPU performance and faster interfaces. It is designed to address time-to-market and power consumption requirements for storage, consumer, and industrial applications while maintaining software compatibility with legacy designs.

Replacement Considerations

Consult the manufacturer's official cross-reference or substitution guide for verified alternative part numbers. Do not assume functional equivalence with other members of the MPC83xx family without verifying pinout and feature differences.
