MPC8314ECVRAGDA

Overview

The MPC8314ECVRAGDA is a PowerQUICC II Pro System-on-Chip (SoC) manufactured by NXP USA Inc. It integrates an e300c3 core operating at up to 400 MHz with 16 KB instruction and data caches, floating-point support, and MMUs. The device features dual enhanced three-speed Ethernet controllers (eTSECs), dual PCI Express x1 interfaces, a 32-bit PCI interface, and a USB 2.0 controller with an on-chip PHY. Memory connectivity is provided via a DDR1/DDR2 SDRAM controller supporting 16- or 32-bit interfaces. Additional peripherals include TDM, SPI, I2C, DUART, GPIO, and timers. The processor includes the SEC 3.3 security engine for cryptographic acceleration and operates within a temperature range of -40°C to 105°C in a 620-pin HBGA package.

Feature Summary

• Integrates a high-performance e300c3 core with floating-point capabilities and hardware memory management units.

FAQ

Does the MPC8314ECVRAGDA include a security engine?

Yes, the MPC8314E incorporates the SEC 3.3 security engine. Note that the non-E variant, MPC8314, does not include this feature.

What memory types are supported by the controller?

The SoC supports both DDR1 and DDR2 SDRAM via a single 16-bit or 32-bit interface.

Can the SerDes interface be used for purposes other than PCI Express?

Yes, when not utilized for PCI Express, the SerDes interface can be configured to support SGMII for Ethernet connectivity.
