NXP Semiconductors KMPC8314EVRAGDA

Overview

KMPC8314EVRAGDA from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor built on Power Architecture™ technology. It features an e300c3 core operating up to 400 MHz, dual enhanced three-speed Ethernet controllers (eTSECs), DDR1/DDR2 memory controller, PCI Express x1 interfaces, USB 2.0 dual-role controller, and SEC 3.3 security engine - all in a single 676-pin PBGA package. It serves as main CPU or I/O processor in network-attached storage (NAS), VoIP gateways, and industrial controllers.

For engineers reviewing the KMPC8314EVRAGDA datasheet, KMPC8314EVRAGDA pinout, KMPC8314EVRAGDA application, or KMPC8314EVRAGDA equivalent, key selection criteria include its 400 MHz e300c3 core, dual eTSECs with SGMII/RGMII support, integrated SEC 3.3 crypto acceleration, DDR2-266 memory interface, and PCI Express root complex/endpoint configurability - critical for secure, high-throughput embedded networking designs.

Technical Context

The KMPC8314EVRAGDA implements a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and MMU, enabling full Linux and real-time OS execution. Its SerDes block supports dual configurable high-speed serial interfaces: either two PCI Express x1 lanes or SGMII for Ethernet PHY interfacing - not both simultaneously.

Security processing is offloaded via SEC 3.3, which includes dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), MDEU (SHA-1/256/384/512, MD5), PKEU (RSA up to 4096-bit), RNG (TRNG + NIST-approved PRNG), and CRCA hardware accelerators - all accessible via descriptor-based DMA without CPU intervention.

Key Specifications

Pinout & Package

KMPC8314EVRAGDA is housed in a 676-ball, 27 mm × 27 mm, 1.0 mm pitch PBGA package (RoHS-compliant, lead-free). Ball pitch and thermal pad layout comply with JEDEC MO-251, supporting standard reflow profiles and thermal vias for industrial ambient operation up to 105°C junction temperature.

FAQ

What is the maximum DDR2 data rate supported by KMPC8314EVRAGDA?

KMPC8314EVRAGDA supports DDR2 SDRAM at up to 266 MHz data rate (DDR2-533), delivering 2.1 GB/s peak bandwidth on its 32-bit interface. This is confirmed in Section 2.4 of the MPC8314EEC Rev. 2 datasheet, which specifies "support for up to 266 MHz data rate" and compatibility with 4-Gbit DDR2 devices using x8/x16 data ports. The controller also supports auto-refresh and on-the-fly CKE-based power management.

Does KMPC8314EVRAGDA include a hardware security engine?

Yes, KMPC8314EVRAGDA integrates the SEC 3.3 security engine, which includes dedicated AESU (128/192/256-bit), DEU (DES/3DES), MDEU (SHA-1/256/384/512, MD5), PKEU (RSA up to 4096-bit), RNG (TRNG + NIST-approved PRNG), and CRCA accelerators. This is explicitly stated in the overview and Section 2.3 of the MPC8314EEC Rev. 2 datasheet, distinguishing it from the non-security MPC8314 variant.

What are the supported Ethernet interface modes for KMPC8314EVRAGDA's eTSECs?

KMPC8314EVRAGDA's dual eTSECs support RGMII, MII, RMII, RTBI, and SGMII physical layer interfaces - but not GMII. Each eTSEC operates independently at 10/100/1000 Mbps and complies with IEEE 802.3, 802.3u, 802.3ab, 802.3z, and IEEE 1588v2 standards. This is documented in Section 2.9 and Figure 1 of the MPC8314EEC Rev. 2 datasheet.

Can KMPC8314EVRAGDA operate in PCI Express root complex mode?

Yes, KMPC8314EVRAGDA's dual PCI Express interfaces are configurable as either root complex or endpoint, supporting both 32-bit and 64-bit addressing, MSI and INTx interrupts, and Traffic Class selection. This flexibility is specified in Section 2.8 of the MPC8314EEC Rev. 2 datasheet and enables use as host for add-in cards or as endpoint in backplane configurations.

What power states does KMPC8314EVRAGDA support beyond normal operation?

KMPC8314EVRAGDA supports PCI Power Management D0–D3hot states plus a proprietary D3warm standby mode. In D3warm, the PMC, one eTSEC, and GTM remain powered via split supply while core and most I/Os are gated - enabling wake-up in <100 µs from magic packet, GPIO, or IRQ. This is detailed in Section 2.11 of the MPC8314EEC Rev. 2 datasheet.
