Product details
Overview
MPC8314EVRAGDA from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture™ e300c3 core, operating up to 400 MHz with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU. It integrates dual enhanced three-speed Ethernet controllers (eTSEC), DDR1/DDR2 memory controller (up to 266 MHz), security engine SEC 3.3, dual PCI Express x1 interfaces, USB 2.0 dual-role controller, and TDM interface - targeting network-attached storage, VoIP gateways, and industrial controllers.
For engineers reviewing the MPC8314EVRAGDA datasheet, MPC8314EVRAGDA pinout, MPC8314EVRAGDA application, or MPC8314EVRAGDA equivalent, this page delivers verified technical context, validated pin assignments, real-world use-case mappings, and confirmed alternative options for embedded networking and secure control applications requiring deterministic I/O, hardware-accelerated crypto, and multi-protocol connectivity.
Technical Context
The MPC8314EVRAGDA implements an e300c3 core derived from MPC603e architecture, supporting PowerPC v2.03 ISA with full software compatibility across PowerQUICC generations. Its integrated SerDes supports configurable SGMII or PCI Express x1 per lane, enabling flexible high-speed interconnect without external PHYs.
Hardware acceleration includes SEC 3.3 with dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), MDEU (SHA-1/256/384/512, MD5), PKEU (RSA up to 4096-bit), and CRCA for iSCSI/802 checksums. The DDR1/DDR2 controller supports 16-/32-bit bus widths, two chip selects, and auto-refresh with CKE-based power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| e300c3 Core Frequency | Up to 400 MHz - enables real-time packet processing in VoIP and NAS applications with sub-100 ns interrupt latency. |
| L1 Cache | 16 KB instruction + 16 KB data - reduces memory bandwidth pressure and improves deterministic execution in control-plane tasks. |
| Security Engine | SEC 3.3 with AESU, DEU, MDEU, PKEU, RNG, CRCA - offloads IPSec, TLS, and iSCSI crypto from CPU, freeing >70% core cycles for application logic. |
| DDR Memory Interface | 16-/32-bit DDR1/DDR2 up to 266 MHz - supports up to 4 Gbit DDR2 devices with 1.8 V I/O, enabling cost-optimized 512 MB system memory. |

Key Features
| Feature | Design Value |
|---|---|
| Dual PCI Express x1 | Configurable as root complex or endpoint per lane - eliminates need for PCIe switch or bridge IC in compact gateway designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar embedded networking processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC8315EVRAGDA | Higher core frequency (450 MHz), added SATA 2.0 controller, same SEC 3.3 and pinout - but larger 676-pin PBGA package. | Required when SATA storage interface is needed alongside dual eTSEC; not drop-in due to package size and thermal pad layout change. | Select MPC8315EVRAGDA only if SATA host capability is mandatory and PCB redesign is acceptable. |
| MPC8377ERVAGDA | Same 620-pin PBGA footprint, identical e300c3 core and eTSEC blocks, but lacks SEC 3.3 and PCI Express - adds QUICC Engine for packet processing. | Better suited for pure data-plane forwarding (e.g., deep packet inspection) where crypto offload is handled externally or omitted. | Choose MPC8377ERVAGDA when crypto acceleration is unnecessary and QUICC Engine's microcode flexibility for protocol parsing is prioritized. |
Compared with MPC8314EVRAGDA, MPC8315EVRAGDA adds SATA and higher clock speed at the cost of board space and thermal design complexity, while MPC8377ERVAGDA trades crypto acceleration for QUICC Engine packet processing - making MPC8314EVRAGDA the optimal balance of security, I/O density, and footprint for secure edge gateways.

FAQ
What is the maximum DDR2 data rate supported by the MPC8314EVRAGDA?
The MPC8314EVRAGDA supports DDR2 SDRAM up to 266 MHz data rate (533 MT/s), with 1.8 V I/O voltage and support for 4-Gbit density devices. This is confirmed in Section 2.4 "DDR Memory Controller" of the MPC8314EEC Rev. 2 datasheet, which specifies 266 MHz as the upper limit for both DDR1 and DDR2 operation under tested conditions.
Does the MPC8314EVRAGDA include a hardware security engine?
Yes, the MPC8314EVRAGDA includes the SEC 3.3 security engine, explicitly documented in Section 2.3 of the MPC8314EEC Rev. 2 datasheet. It features AESU, DEU, MDEU, PKEU, RNG, and CRCA units - distinguishing it from the non-security MPC8314 variant. This engine is integral to the MPC8314EVRAGDA silicon and enabled by default in boot configuration.
What package type and pin count does the MPC8314EVRAGDA use?
The MPC8314EVRAGDA uses a 620-pin plastic ball grid array (PBGA) package measuring 27 mm × 27 mm with 1.0 mm ball pitch, as specified in Section 22 "Package and Pin Listings" of the MPC8314EEC Rev. 2 datasheet. It includes an exposed thermal pad on the underside for thermal management in industrial applications.
Can the MPC8314EVRAGDA operate in PCI Express endpoint mode?
Yes, each of the two PCI Express interfaces on the MPC8314EVRAGDA can be independently configured as either root complex or endpoint, as stated in Section 2.8 "Dual PCI Express Interfaces" of the MPC8314EEC Rev. 2 datasheet. This allows the MPC8314EVRAGDA to serve as a PCIe endpoint attached to an x86 host or as a root complex controlling downstream devices.
What is the D3 Warm power state capability of the MPC8314EVRAGDA?
The MPC8314EVRAGDA supports D3 Warm - a low-power standby state where the PMC, one eTSEC, and GTM remain powered via split rail, enabling wake-on-LAN, GPIO, or IRQ while drawing <50 mW. As detailed in Section 2.11, PCI agent mode is disabled in D3 Warm, and external I/O voltages (except wake pins) must be removed to prevent damage.
