NXP Semiconductors MPC8313EVRAFF

Overview

MPC8313EVRAFF from NXP Semiconductors (formerly Freescale) is an embedded Power Architecture™ e300c3-core communications processor targeting industrial control, network access servers, and intelligent NIC applications. It integrates dual 10/100/1000 Mbps Ethernet MACs, DDR1/DDR2 memory controller (up to 333 MHz), 32-bit PCI interface (66 MHz), USB 2.0 dual-role controller with on-chip PHY, and hardware security engine SEC 2.2 supporting AES, DES, SHA-1, and MD-5.

For engineers reviewing the MPC8313EVRAFF datasheet, MPC8313EVRAFF pinout, MPC8313EVRAFF application, or MPC8313EVRAFF equivalent, key selection considerations include its 333 MHz e300c3 core frequency, dual RGMII/SGMII Ethernet interfaces, DDR2-333 support at 1.8 V, PCI 2.3 compliance, and integrated security acceleration - all in a 620-pin PBGA package with industrial temperature range (–40°C to +105°C).

Technical Context

The MPC8313EVRAFF implements a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units. Its dual enhanced three-speed Ethernet controllers (eTSECs) support IEEE 802.3/802.3u/802.3ab/802.1588, TCP/IP offload (checksum, VLAN, jumbo frames), and eight transmit/receive queues per MAC.

It features a dedicated security engine (SEC 2.2) with one crypto-channel and execution units for DES/3DES, AES, and SHA-1/MD-5, enabling control- and data-plane acceleration. The DDR1/DDR2 controller supports 16-/32-bit buses, up to 2-Gbit DDR1 or 4-Gbit DDR2 devices, auto-refresh, and CKE-based power management.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313EVRAFF?

The MPC8313EVRAFF DDR2 controller supports up to 333 MHz clock frequency, enabling DDR2-667 operation (333 MT/s). This corresponds to a peak theoretical bandwidth of 2.7 GB/s on a 32-bit bus. The controller is fully compatible with JEDEC-standard DDR2 SDRAM components rated for 1.8 V operation and supports 4-Gbit density devices with x8/x16/x32 data widths. MPC8313EVRAFF achieves this using programmable timing registers and on-the-fly power management via CKE.

Does the MPC8313EVRAFF include an on-chip USB 2.0 PHY?

Yes, the MPC8313EVRAFF integrates a full-speed/high-speed USB 2.0 PHY compliant with the Universal Serial Bus Specification Rev. 2.0. It supports host, device, and OTG roles without requiring an external transceiver. The PHY connects directly to USB_DP and USB_DM pins and handles 480 Mbps high-speed signaling, 12 Mbps full-speed, and 1.5 Mbps low-speed (host mode only). MPC8313EVRAFF also supports ULPI interface for external PHY attachment if needed.

What Ethernet physical layer interfaces does the MPC8313EVRAFF support?

The MPC8313EVRAFF dual eTSECs support RGMII, SGMII, MII, RMII, and RTBI physical interfaces. Each eTSEC can be independently configured for any of these modes, enabling flexible PHY selection - for example, RGMII for low-pin-count Gigabit PHYs or SGMII for backplane interconnects. MPC8313EVRAFF includes on-chip high-speed serial interface logic for SGMII and supports IEEE 1588 hardware timestamping on all modes.

Is the MPC8313EVRAFF pin-compatible with other PowerQUICC II Pro processors?

No, the MPC8313EVRAFF is not pin-compatible with other members of the PowerQUICC II Pro family such as MPC8315E or MPC8377E. While all use 620-pin PBGA packages, pin assignments differ significantly - especially for DDR, PCI, and security-related signals. MPC8313EVRAFF has unique ball mapping defined in Section 19 of its hardware specifications. Migration to alternative parts requires PCB redesign and signal re-routing.

What security algorithms are accelerated by the MPC8313EVRAFF's SEC 2.2 engine?

The MPC8313EVRAFF security engine SEC 2.2 accelerates DES, 3DES, AES (all key lengths), SHA-1, MD-5, SHA-224, SHA-256, and HMAC with any hash algorithm. It implements one crypto-channel with dedicated execution units: DEU for DES/3DES, AESU for AES, and MDEU for message digests. MPC8313EVRAFF uses this to accelerate IPSec, IEEE 802.11i, and iSCSI protocols in both control and data planes.
