NXP Semiconductors MPC8313VRAGDC

Overview

MPC8313VRAGDC from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II Pro embedded communications processor featuring the e300c3 Power Architecture™ core running at 333 MHz, dual three-speed 10/100/1000 Mbps Ethernet MACs with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (up to 333 MHz, 32-bit), integrated USB 2.0 dual-role controller with on-chip PHY, and 32-bit PCI interface operating at up to 66 MHz. It serves as a main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313VRAGDC datasheet, MPC8313VRAGDC pinout, MPC8313VRAGDC application, or MPC8313VRAGDC equivalent, key selection considerations include its e300c3 core frequency, dual eTSEC timing and interface modes, DDR1/DDR2 voltage and timing compatibility (1.8 V / 2.5 V), PCI 3.3-V compliance, and USB 2.0 OTG capability with ULPI or on-chip PHY support.

Technical Context

The MPC8313VRAGDC implements a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, coupled with a unified memory subsystem supporting DDR1 and DDR2 SDRAM at up to 333 MHz. Its dual enhanced three-speed Ethernet controllers (eTSECs) provide hardware-accelerated TCP/IP checksum offload, VLAN/PPPoE/MPLS header recognition, and IEEE 1588 timestamping - all without a security engine (unlike the MPC8313E variant).

It integrates a 32-bit PCI controller compliant with PCI Spec 2.3 (3.3-V only), an enhanced local bus controller supporting up to 66 MHz asynchronous/synchronous operation, and a programmable interrupt controller managing 39 discrete sources. Clocking relies on external SYS_CLK_IN (24–66.67 MHz) with internal PLL lock time ≤100 µs, and power sequencing requires VDD applied before GVDD/NVDD/LVDD to prevent I/O contention.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with MPC8313EVRAGDC, MPC8313VRAGDC omits the security engine to reduce cost and power, making it optimal for non-encrypted control-plane applications; compared with MPC8315EVRAGDC, it provides identical core and eTSEC functionality in a smaller footprint and lower BOM cost, ideal for cost-sensitive single-port networking gear.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313VRAGDC?

The MPC8313VRAGDC DDR2 interface supports up to 333 MHz clock frequency, enabling 666 MT/s effective data rate on a 32-bit bus. This is confirmed in Section 1.4 of the MPC8313EEC Rev. 4 datasheet, which specifies "support for up to 333 MHz" and "64-Mbit to 4-Gbit devices" under DDR2 operation with GVDD = 1.8 V ± 80 mV. The MPC8313VRAGDC does not support DDR2-800 or higher rates.

Does the MPC8313VRAGDC include a hardware security engine?

No, the MPC8313VRAGDC does not include a security engine. Figure 1 in the MPC8313EEC Rev. 4 datasheet explicitly notes "Note: The MPC8313 does not include a security engine," distinguishing it from the MPC8313E variant. Cryptographic operations such as AES or SHA must be performed in software on the e300c3 core or offloaded to an external accelerator when using MPC8313VRAGDC.

What are the power sequencing requirements for reliable startup of the MPC8313VRAGDC?

The MPC8313VRAGDC requires VDD (core) to rise to ≥90% of nominal (1.0 V) before any I/O supply (GVDD, NVDD, LVDD) reaches 0.7 V, followed by ≥32 SYS_CLK_IN or PCI_SYNC_IN cycles after PORESET deassertion. This is specified in Section 2.2 ("Power Sequencing") of MPC8313EEC Rev. 4 to prevent I/O contention and excessive current draw during ramp-up.

Can the MPC8313VRAGDC operate in PCI agent mode with a 3.3-V PCI bus?

Yes, the MPC8313VRAGDC PCI interface is fully compliant with PCI Specification Revision 2.3 and supports 3.3-V signaling only - it is not 5-V tolerant. Section 1.5 confirms "PCI 3.3-V compatible (not 5-V compatible)" and supports both host and agent modes, including PME detection in host mode and PME generation in agent mode, as verified in Table 2 and Section 1.9.

What Ethernet PHY interfaces are supported by the MPC8313VRAGDC eTSECs?

The MPC8313VRAGDC dual eTSECs support RGMII, SGMII, MII, RMII, and RTBI physical layer interfaces, as stated in Section 1.7. Each eTSEC can be independently configured for any of these modes - for example, eTSEC1 in RGMII for a copper GbE port and eTSEC2 in SGMII for fiber uplink - with full IEEE 802.3/802.3u/802.3ab compliance and Wake-on-Magic Packet™ support.
