NXP Semiconductors MPC8313CVRADDC

Overview

MPC8313CVRADDC from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring the e300c3 Power Architecture core, dual 10/100/1000 Mbps Ethernet controllers, DDR1/DDR2 memory controller, PCI 2.3 interface, USB 2.0 dual-role controller with on-chip PHY, and integrated programmable interrupt controller - deployed as main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313CVRADDC datasheet, MPC8313CVRADDC pinout, MPC8313CVRADDC application, or MPC8313CVRADDC equivalent, key selection considerations include its 333 MHz e300c3 core frequency, dual eTSEC RGMII/SGMII/MII support, 1.0 V core supply, 32-bit PCI host/agent operation, and DDR2-333 memory interface compatibility - all validated for embedded networking and control systems requiring deterministic real-time I/O and cryptographic offload capability.

Technical Context

The MPC8313CVRADDC implements a single-issue, in-order e300c3 core with 16 KB instruction and 16 KB data caches, FPU, and two integer units, operating at up to 333 MHz. Its memory subsystem integrates a unified DDR1/DDR2 controller supporting 16-/32-bit buses at 333 MHz with auto-refresh, CKE-based power management, and 1.8 V / 2.5 V SSTL2-compatible I/O.

Peripherals include two IEEE 802.3-compliant eTSECs with RGMII/SGMII/MII/RMII/RTBI interfaces, TCP/IP acceleration (VLAN, MPLS, ESP/AH header recognition), and IEEE 1588 timestamping; a 32-bit PCI 2.3 controller (66 MHz, 3.3 V only); USB 2.0 dual-role controller with ULPI/PHY options; and four-channel DMA, dual I²C, DUART, SPI, GPIO, and timers - all managed via an integrated programmable interrupt controller supporting 39 discrete sources.

FAQ

What is the maximum DDR2 data rate supported by the MPC8313CVRADDC?

The MPC8313CVRADDC supports DDR2 SDRAM at up to 333 MHz (DDR2-667), with 1.8 V I/O voltage and 18 Ω output drive impedance. It handles 64-Mbit to 4-Gbit DDR2 devices using x8/x16/x32 data widths and supports up to 16 simultaneous open pages - verified in Section 1.4 of the MPC8313EEC Rev. 4 datasheet. This capability is fully implemented in the MPC8313CVRADDC silicon revision.

Does the MPC8313CVRADDC include a hardware security engine?

No, the MPC8313CVRADDC does not include a security engine. As explicitly stated in the block diagram footnote of the MPC8313E Hardware Specifications (Rev. 4, p.3), "The MPC8313 does not include a security engine." This distinguishes it from the MPC8315CVRADDC, which integrates SEC 2.2. Cryptographic operations must be performed in software on the e300c3 core when using the MPC8313CVRADDC.

What are the power sequencing requirements for reliable MPC8313CVRADDC startup?

The MPC8313CVRADDC requires core voltage (VDD/VDDC = 1.0 V ± 50 mV) to reach 90% of nominal before any I/O supply (GVDD, NVDD, LVDDA) exceeds 0.7 V, followed by ≥32 SYS_CLK_IN cycles after PORESET deassertion. This sequence prevents I/O contention and ensures proper PLL lock within 100 µs - detailed in Section 2.2 of the MPC8313EEC Rev. 4 datasheet. Failure to follow this causes undefined reset behavior.

Can the MPC8313CVRADDC operate in PCI host mode with 5 V signaling?

No, the MPC8313CVRADDC PCI interface is strictly 3.3 V compatible and not 5 V tolerant, as confirmed in Section 1.5 of the MPC8313EEC Rev. 4 datasheet. Attempting 5 V signaling risks permanent damage to the PCI_AD[31:0] and control pins. External level-shifting circuitry is required if interfacing with legacy 5 V PCI slots.

What Ethernet physical layer interfaces does the MPC8313CVRADDC support natively?

The MPC8313CVRADDC supports RGMII, SGMII, MII, RMII, and RTBI interfaces across its dual eTSECs - all implemented in silicon and validated per IEEE 802.3 standards. The on-chip high-speed serial interface connects directly to external SGMII PHYs, while RGMII/MII signals are routed to external magnetics or PHYs. No external SerDes or level shifters are needed for these modes, as specified in Section 1.7.
