NXP Semiconductors MPC8313ECVRAFF

Overview

MPC8313ECVRAFF from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring an 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), integrated USB 2.0 dual-role controller with on-chip PHY, and PCI 2.3 interface - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313ECVRAFF datasheet, MPC8313ECVRAFF pinout, MPC8313ECVRAFF application, or MPC8313ECVRAFF equivalent, key selection criteria include its 333 MHz e300c3 core performance, dual GbE MAC timing and offload capabilities, DDR2-333 memory interface voltage tolerance (1.8 V ±80 mV), and PCI 3.3-V/66-MHz host-agent mode flexibility in embedded networking designs.

Technical Context

The MPC8313ECVRAFF integrates a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, coupled with a dedicated security engine (SEC 2.2) supporting DES/3DES/AES/SHA-1/MD5 acceleration. Its clock architecture uses a programmable PLL with 100 µs lock time and supports SYS_CLK_IN or PCI_SYNC_IN as primary reference (24–66.67 MHz).

Memory subsystem includes a single 16-/32-bit DDR1/DDR2 controller with auto-refresh, CKE-based power management, and support for up to 4-Gbit DDR2 devices; peripheral interconnect comprises a 32-bit PCI 2.3 interface (66 MHz, 3.3-V only), enhanced local bus (66 MHz), dual I²C, SPI, DUART, and four-channel DMA - all managed via a programmable interrupt controller handling 5 external + 34 internal sources.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313ECVRAFF?

The MPC8313ECVRAFF supports DDR2 SDRAM at up to 333 MHz (effective 667 MT/s), with GVDD = 1.8 V ±80 mV. It implements a single 16-/32-bit interface capable of addressing up to 4-Gbit DDR2 devices using x8/x16/x32 configurations, and supports auto-refresh, CKE-based power-down, and 16 simultaneous open pages - enabling sustained bandwidth for packet buffering in dual-GbE applications.

Does the MPC8313ECVRAFF include an integrated USB PHY?

Yes, the MPC8313ECVRAFF includes an on-chip USB 2.0 full-speed/high-speed PHY compliant with the Universal Serial Bus Specification Rev. 2.0. This eliminates the need for an external ULPI transceiver when implementing USB device, host, or OTG functionality - reducing BOM cost and PCB area while maintaining support for 480 Mbps high-speed, 12 Mbps full-speed, and 1.5 Mbps low-speed (host-only) operation.

What are the power sequencing requirements for the MPC8313ECVRAFF?

The MPC8313ECVRAFF requires core voltage (VDD = 1.0 V ±50 mV) to be applied before I/O supplies (GVDD, NVDD, LVDDA/LVDDB). PORESET must be asserted until at least 32 SYS_CLK_IN or PCI_SYNC_IN cycles after all supplies stabilize. Violating this sequence risks I/O contention and excessive current draw during power ramp-up - confirmed in Section 2.2 of the MPC8313EEC Rev. 4 datasheet.

Can the MPC8313ECVRAFF operate in PCI agent mode?

Yes, the MPC8313ECVRAFF supports both PCI host and agent modes via configuration pins and SCCR register settings. In agent mode, it uses PCI_SYNC_IN as clock reference, supports PME detection, and complies with PCI 2.3 specification at 33/66 MHz. The on-chip arbiter handles up to three external PCI masters, and hardware-enforced coherency is selectable - enabling use as a peripheral controller behind a host bridge.

Is the security engine present in all MPC8313E revisions?

No - the MPC8313E security engine (SEC 2.2) is present only in the MPC8313E variant, not in the base MPC8313. The MPC8313ECVRAFF part number corresponds to the MPC8313E revision and therefore includes SEC 2.2 hardware acceleration for DES/3DES/AES/SHA-1/MD5, as explicitly stated in Section 1.3 and Figure 1 of the MPC8313EEC Rev. 4 datasheet.
