NXP Semiconductors MPC8315VRAGDA

Overview

MPC8315VRAGDA from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor built on Power Architecture™ technology, featuring an e300c3 core operating at up to 400 MHz, dual 10/100/1000 Mbps Ethernet controllers (eTSECs), dual SATA 3 Gbps interfaces, and a 32-bit PCI interface running at up to 66 MHz. It serves as a main CPU or I/O processor in network-attached storage (NAS), VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315VRAGDA datasheet, MPC8315VRAGDA pinout, MPC8315VRAGDA application, or MPC8315VRAGDA equivalent, this page delivers verified technical context, validated package mapping, confirmed peripheral integration (eTSEC, SATA, PCI, DDR2), and real-world selection guidance for embedded storage and communications systems.

Technical Context

The MPC8315VRAGDA implements an e300c3 core with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU support - enabling full Linux and real-time OS execution. Its integrated SerDes supports configurable SGMII, PCI Express x1, or SATA PHY modes per lane.

It integrates dual eTSECs compliant with IEEE 802.3, 802.3ab, and IEEE 1588, plus a DDR1/DDR2 memory controller supporting up to 266 MHz data rates and two physical banks. Unlike the MPC8315E, the MPC8315VRAGDA excludes the security engine (SEC 3.3) and associated crypto acceleration units.

MPC8315VRAGDA is available at Aetrix Electronics and suitable for network-attached storage (NAS), voice over IP (VoIP) gateways, and industrial Ethernet controllers requiring stable component supply across extended product lifecycles.

Supply support for MPC8315VRAGDA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) is a fabless semiconductor company specializing in embedded processing, connectivity, and analog solutions for automotive, industrial, and networking markets.

The MPC8315VRAGDA belongs to the PowerQUICC II Pro family - designed specifically for cost-sensitive, low-power communications infrastructure where integration of CPU, Ethernet, SATA, and PCI reduces system complexity and bill-of-materials cost.

FAQ

What is the maximum DDR2 data rate supported by the MPC8315VRAGDA?

The MPC8315VRAGDA supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s), with configurable 16- or 32-bit bus width and support for up to 4-Gbit density devices. This enables sustained memory bandwidth exceeding 2.1 GB/s in 32-bit mode - sufficient for concurrent packet buffering and file system caching in NAS applications. The DDR2 controller also supports auto-refresh and on-the-fly CKE-based power management.

Does the MPC8315VRAGDA include a security engine?

No, the MPC8315VRAGDA does not include a security engine. Documentation explicitly states "the MPC8315 do not include a security engine," distinguishing it from the MPC8315E variant. Therefore, MPC8315VRAGDA lacks hardware acceleration for AES, DES, SHA, RSA, or RNG operations - all cryptographic processing must be performed in software on the e300c3 core. For secure applications, the MPC8315EVRAGDA or external crypto co-processor is required.

What Ethernet standards does the MPC8315VRAGDA's eTSEC support?

The MPC8315VRAGDA integrates two enhanced Three-Speed Ethernet Controllers (eTSECs) compliant with IEEE Std 802.3™, 802.3u™, 802.3x™, 802.3z™, 802.3au™, 802.3ab™, and IEEE Std 1588™. Each eTSEC supports RGMII, MII, RMII, RTBI, and SGMII physical layer interfaces - enabling 10/100/1000 Mbps operation with hardware timestamping for precision time protocol (PTP) synchronization in industrial control networks.

What is the package type and thermal specification of the MPC8315VRAGDA?

The MPC8315VRAGDA uses a 620-pin Plastic Ball Grid Array (PBGA) package measuring 35 mm × 35 mm with 1.0 mm ball pitch. Its junction temperature range is specified from 0 °C to 105 °C, and it features an exposed thermal pad on the underside for direct heatsink mounting. Thermal resistance (θ_JA) is 17.5 °C/W under JEDEC JESD51-2 conditions - requiring a minimum 4-layer PCB with dedicated ground/power planes and ≥4 thermal vias under the pad for reliable operation at 400 MHz.

Can the MPC8315VRAGDA operate in PCI host mode?

Yes, the MPC8315VRAGDA supports PCI host mode via its integrated 32-bit PCI controller compliant with PCI Local Bus Specification Revision 2.3. In host mode, it can manage up to three external PCI masters and provides hardware-enforced coherency. The controller operates at 33 or 66 MHz, is 3.3-V compatible only, and includes on-chip arbitration - enabling direct connection to legacy PCI peripherals such as modems, encryption cards, or video capture devices without bridge logic.
