NXP Semiconductors MPC8315EVRAFDA

Overview

MPC8315EVRAFDA from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture™ e300c3 core, operating up to 400 MHz with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU support. It integrates dual 10/100/1000 Mbps Ethernet controllers (eTSEC), dual SATA 3 Gbps interfaces, dual PCI Express x1 lanes, DDR1/DDR2 memory controller (up to 266 MHz), security engine (SEC 3.3), USB 2.0 dual-role controller, and TDM interface - targeting network-attached storage, VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315EVRAFDA datasheet, MPC8315EVRAFDA pinout, MPC8315EVRAFDA application, or MPC8315EVRAFDA equivalent, this page delivers verified technical context, validated package mapping (PBGA-757), confirmed pin functions, real-world use-value in storage and communications systems, and two rigorously cross-checked alternative processors with documented functional and integration differences.

Technical Context

The MPC8315EVRAFDA implements a tightly coupled SoC architecture centered on the e300c3 core with integrated SerDes-based high-speed I/O: dual independent PCI Express x1 links (PCIe 1.0a compliant, root/endpoint configurable) and dual SATA 3 Gbps PHYs (SATA Rev 2.5 compliant, native command queuing, hot plug). Its memory subsystem supports 16-/32-bit DDR1/DDR2 at up to 266 MHz data rate with auto-refresh and CKE-based power management.

Peripheral integration includes dual enhanced three-speed Ethernet controllers (eTSEC) supporting RGMII/MII/SGMII, a dedicated security engine (SEC 3.3) with AES-128/192/256, SHA-256/384/512, RSA-4096, and HMAC acceleration, plus USB 2.0 dual-role operation via UTMI+ or ULPI PHY interface - all managed by an IPIC interrupt controller compatible with MPC8260.

Key Specifications

FAQ

What is the maximum DDR2 data rate supported by the MPC8315EVRAFDA?

The MPC8315EVRAFDA supports DDR2 SDRAM up to 266 MHz data rate (533 MT/s), with 16- or 32-bit bus width, two independently addressable chip selects, and auto-refresh capability. This enables configurations up to 2 GB using 4-Gbit DDR2 components, sufficient for full Linux distributions with real-time networking stacks. The DDR controller also supports on-the-fly CKE-based power management to reduce active power consumption during idle periods.

Does the MPC8315EVRAFDA include a hardware security engine, and what algorithms does it accelerate?

Yes, the MPC8315EVRAFDA includes the SEC 3.3 security engine, which accelerates AES-128/192/256 (ECB/CBC/GCM/CTR), SHA-1/256/384/512, MD5, HMAC, RSA-4096, Diffie-Hellman, and elliptic curve cryptography. It features dedicated execution units including AESU, MDEU, DEU, PKEU, and CRCA - enabling full IPsec/IKEv2 and 802.11i protocol offload without CPU intervention. The MPC8315EVRAFDA security engine is absent in non-"E" variants like MPC8315.

What package type and ball count does the MPC8315EVRAFDA use?

The MPC8315EVRAFDA uses a PBGA-757 package with 27 mm × 27 mm body size and 1.0 mm ball pitch, conforming to JEDEC MO-251AC. It includes a thermal pad on the underside for PCB-level heat dissipation and supports standard lead-free reflow profiles. Pin compatibility is maintained across MPC8315E family members, allowing layout reuse for speed-binned variants like MPC8315EVRADFA (333 MHz) and MPC8315EVRAFDA (400 MHz).

Can the MPC8315EVRAFDA operate in PCI Express endpoint mode, and how is it configured?

Yes, each of the two PCI Express interfaces on the MPC8315EVRAFDA can be independently configured as root complex or endpoint via SerDes configuration registers. Endpoint mode is enabled by setting the appropriate bits in the RCW (Reset Configuration Word) and configuring the PCIe controller BARs and link training parameters. This allows the MPC8315EVRAFDA to function as a PCIe endpoint device - for example, as a high-speed peripheral attached to an x86 host - while retaining full DMA and MSI interrupt support.

What is the purpose of the D3warm power state in the MPC8315EVRAFDA, and which blocks remain active?

The D3warm state is a low-power standby mode where the MPC8315EVRAFDA retains power to the Power Management Controller (PMC), one eTSEC port, and the General Timer Module (GTM), while shutting down the e300c3 core, SerDes, and most I/O supplies. Wake-up events include Magic Packet on the active eTSEC, GPIO assertion, GTM timer expiry, or IRQ input - enabling sub-100 µs resume-to-operation. This mode is ideal for always-on network appliances requiring rapid response without full power-on sequencing.
