NXP Semiconductors MPC8313EVRAFFC

Overview

MPC8313EVRAFFC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an e300c3 Power Architecture core running at 333 MHz, dual 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (up to 333 MHz), integrated security engine SEC 2.2, and USB 2.0 dual-role controller with on-chip PHY - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313EVRAFFC datasheet, MPC8313EVRAFFC pinout, MPC8313EVRAFFC application, or MPC8313EVRAFFC equivalent, key selection criteria include e300c3 core frequency, dual eTSEC interface configuration, DDR1/DDR2 voltage compatibility (1.8 V / 2.5 V), PCI 2.3 compliance, and SEC 2.2 cryptographic acceleration for IPSec/802.11i.

Technical Context

The MPC8313EVRAFFC integrates an 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/1588, with hardware TCP/IP offload including VLAN, MPLS, and IPsec header recognition.

It features a unified DDR1/DDR2 SDRAM controller supporting 16-/32-bit buses at up to 333 MHz, a 32-bit PCI 2.3-compliant interface operating at 66 MHz, and a dedicated security engine (SEC 2.2) with DEU, AESU, and MDEU execution units accelerating DES, 3DES, AES, SHA-1, SHA-256, and HMAC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar communications processor applications.

Compared with MPC8313EVRAFFC, MPC8315EVRADDC trades security acceleration for SATA connectivity in the same footprint, while MPC8377ERVAAH delivers higher CPU bandwidth and PCIe at the cost of increased power and layout complexity - both require PCB redesign due to non-pin-compatible pinouts and voltage rail changes.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313EVRAFFC?

The MPC8313EVRAFFC supports DDR2 SDRAM at up to 333 MHz (166 MHz clock, double-data-rate), delivering 5.3 GB/s peak bandwidth on a 32-bit bus. This is confirmed in Section 1.4 of the MPC8313E Hardware Specifications Rev. 4, which specifies "support for up to 333 MHz" and "64-Mbit to 4-Gbit devices" for DDR2. The MPC8313EVRAFFC implements this capability using its GVDD = 1.8 V ± 80 mV supply rail.

Does the MPC8313EVRAFFC include a hardware security engine?

Yes, the MPC8313EVRAFFC includes the SEC 2.2 security engine, as explicitly stated in Section 1.3 and Figure 1 of the MPC8313E Hardware Specifications Rev. 4. It provides hardware acceleration for DES, 3DES, AES, SHA-1, SHA-256, and HMAC algorithms, with one crypto-channel and dedicated execution units (DEU, AESU, MDEU). Note that the base MPC8313 (non-E) variant lacks this engine, but MPC8313EVRAFFC is an MPC8313E revision.

What Ethernet physical interfaces does the MPC8313EVRAFFC support?

The MPC8313EVRAFFC supports RGMII, SGMII, MII, RMII, and RTBI physical interfaces across its two eTSEC controllers, as documented in Section 1.7. 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 serial backplane interconnects. The on-chip high-speed serial interface facilitates direct connection to SGMII-capable PHYs.

Is the MPC8313EVRAFFC pin-compatible with other PowerQUICC II Pro processors?

No, the MPC8313EVRAFFC is not pin-compatible with other PowerQUICC II Pro processors such as MPC8315E or MPC8377E. Although all use PBGA-620 packages, Freescale's documentation confirms distinct pin mappings: Section 19 of the MPC8313E Hardware Specifications lists unique signal assignments, and MPC8315E/MPC8377E datasheets show incompatible ballouts for DDR, PCI, and security-related signals. Migration requires PCB redesign.

What is the recommended power-up sequence for the MPC8313EVRAFFC?

The recommended power-up sequence for MPC8313EVRAFFC requires applying core voltage (VDD = 1.0 V ± 50 mV) before I/O voltages (GVDD, NVDD, LVDDA/LVDDB), with PORESET asserted until at least 32 SYS_CLK_IN or PCI_SYNC_IN cycles after supplies stabilize. This is specified in Section 2.2 "Power Sequencing" of the Hardware Specifications Rev. 4 to prevent I/O contention and excessive current draw during ramp-up.
