NXP Semiconductors MPC8313VRADDB

Overview

MPC8313VRADDB from NXP Semiconductors (formerly Freescale) is a PowerQUICC II Pro communications processor featuring the e300c3 Power Architecture core operating at up to 333 MHz, dual 10/100/1000 Mbps Ethernet controllers with RGMII/SGMII/MII support, DDR1/DDR2 memory controller (16-/32-bit, up to 333 MHz), 32-bit PCI interface (66 MHz), USB 2.0 dual-role controller with on-chip PHY, and integrated security acceleration (SEC 2.2). It serves as a main CPU or I/O processor in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the MPC8313VRADDB datasheet, MPC8313VRADDB pinout, MPC8313VRADDB application, or MPC8313VRADDB equivalent, key selection criteria include its e300c3 core frequency, dual GbE MAC timing compliance (IEEE 802.3ab/z), DDR2 1.8 V I/O voltage support, PCI 3.3-V compatibility, and absence of on-chip security engine - confirmed by Freescale documentation noting "The MPC8313 does not include a security engine."

Technical Context

The MPC8313VRADDB implements a superscalar e300c3 core with 16 KB instruction and 16 KB data caches, floating-point unit, and two integer units. Its memory subsystem integrates a single DDR1/DDR2 controller supporting 16- or 32-bit bus widths, two physical banks, and auto-refresh with CKE-based power management.

Peripheral integration includes dual enhanced three-speed Ethernet controllers (eTSECs) compliant with IEEE 802.3, 802.3u, 802.3ab, and 802.1588, each with 10-KB TX and 2-KB RX FIFOs, VLAN/PPPoE/MPLS header recognition, and TCP/IP checksum offload. The device lacks SEC 2.2 hardware - a documented distinction from the MPC8313E variant.

FAQ

Does MPC8313VRADDB include an integrated security engine?

No, MPC8313VRADDB does not include a security engine. Freescale documentation explicitly states "The MPC8313 does not include a security engine," distinguishing it from the MPC8313E variant which integrates SEC 2.2 for DES/3DES/AES/SHA-1 acceleration. This omission reduces core power consumption and die area, making MPC8313VRADDB suitable for applications where cryptographic offload is handled in software or by external ICs.

What DDR2 memory configurations does MPC8313VRADDB support?

MPC8313VRADDB supports DDR2 SDRAM with 1.8 V I/O voltage, up to 333 MHz clock rate, and 16- or 32-bit bus widths. It accommodates devices from 64 Mbit to 4 Gbit density with x8/x16/x32 data ports, two independently addressable chip selects, up to 16 open pages, and auto-refresh with CKE-based power management - verified in Section 1.4 of the MPC8313E Hardware Specifications document.

Is MPC8313VRADDB pin-compatible with MPC8313EVRADDB?

Yes, MPC8313VRADDB is pin-compatible with MPC8313EVRADDB. Both variants use the identical PBGA-620 package with matching pin assignments for core, memory, Ethernet, PCI, USB, and power domains. The sole functional difference is the absence of SEC 2.2 in MPC8313VRADDB, allowing direct PCB reuse when crypto acceleration is unnecessary.

What Ethernet PHY interfaces are supported by MPC8313VRADDB's eTSECs?

MPC8313VRADDB's dual eTSECs support RGMII, SGMII, MII, RMII, and RTBI physical layer interfaces. SGMII mode enables direct connection to external SGMII-capable PHYs without MDIO/MDC signaling, while RGMII allows low-pin-count 1.8 V or 2.5 V interface to standard Gigabit PHYs - both confirmed in Section 1.7 of the official hardware specifications.

What is the maximum junction temperature rating for MPC8313VRADDB?

The maximum junction temperature (TJ) for MPC8313VRADDB is 105°C, as specified in Table 2 ("Recommended Operating Conditions") of the MPC8313E Hardware Specifications document. This rating applies across all operating modes including D3 warm low-power state, and requires adherence to thermal design guidelines in Section 21 for heatsink sizing and PCB copper pour.
