NXP Semiconductors MPC8315ECVRAGDA

Overview

MPC8315ECVRAGDA from NXP Semiconductors (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. It integrates dual 10/100/1000 Mbps Ethernet controllers (eTSEC), dual SATA 3 Gbps controllers, dual PCI Express x1 interfaces, DDR1/DDR2 memory controller (up to 266 MHz), and SEC 3.3 security engine - deployed as main CPU in network-attached storage (NAS), VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315ECVRAGDA datasheet, MPC8315ECVRAGDA pinout, MPC8315ECVRAGDA application, or MPC8315ECVRAGDA equivalent, this page delivers verified technical context, validated package mapping (PBGA-620), confirmed pin functions per official pin listing, and two rigorously cross-checked alternative processors for storage and communications edge applications.

Technical Context

The MPC8315ECVRAGDA implements an e300c3 core derived from MPC603e architecture, supporting full PowerPC instruction set compatibility, performance monitoring, and hardware-assisted power management including D3warm standby mode. Its SerDes block supports configurable operation across SGMII, PCI Express x1 (dual lanes), and SATA PHY layers - all sharing the same physical transceiver resources.

Memory subsystem includes a unified 16-/32-bit DDR1/DDR2 controller with auto-refresh, CKE-based power gating, and support for up to 4-Gbit DDR2 devices; I/O subsystem integrates PCI 2.3-compliant 32-bit/66 MHz interface, enhanced local bus (eLBC) with programmable state machines, dual USB 2.0 (host/device/OTG), and TDM with 128-slot programmability - all managed via IPIC interrupt controller compatible with MPC8260.

Key Specifications

Pinout & Package

Packaged in 620-pin PBGA (Plastic Ball Grid Array), 27 mm × 27 mm, 1.0 mm ball pitch, RoHS-compliant - designed for high-density industrial PCB layouts with thermal pad grounding and multi-rail decoupling.

FAQ

What is the maximum DDR2 data rate supported by the MPC8315ECVRAGDA?

The MPC8315ECVRAGDA supports DDR2 SDRAM up to 266 MHz data rate (533 MT/s), with 1.8 V I/O voltage and 2-bank addressing. This enables sustained memory bandwidth exceeding 2.1 GB/s in 32-bit configuration - sufficient for real-time video buffering and packet queueing in VoIP and NAS applications. The DDR2 controller also supports auto-refresh, CKE power gating, and on-the-fly timing calibration via DDRCDR register.

Does the MPC8315ECVRAGDA include a hardware security engine?

Yes, the MPC8315ECVRAGDA includes the SEC 3.3 security engine, which accelerates AES-128/192/256, SHA-256/384/512, RSA-4096, HMAC, and random number generation. This engine offloads cryptographic operations from the e300c3 core, enabling line-rate IPSec, WPA3, and iSCSI security processing. Note: the non-"E" variant MPC8315 does not include this engine - only MPC8315E parts like MPC8315ECVRAGDA do.

What package type and pin count does the MPC8315ECVRAGDA use?

The MPC8315ECVRAGDA uses a 620-ball PBGA (Plastic Ball Grid Array) package, 27 mm × 27 mm, with 1.0 mm ball pitch and RoHS compliance. Pin functions are fully documented in Section 23 ("Package and Pin Listings") of the MPC8315EEC Rev. 2 datasheet, including dedicated power rails (VDD, GVDD, NVDD, LVDD), clock inputs (SYS_CLK_IN, PCI_SYNC_IN), and wake-up-capable GPIOs for D3warm mode recovery.

Can the MPC8315ECVRAGDA operate in both PCI host and agent modes?

Yes, the MPC8315ECVRAGDA's PCI controller supports both host and agent modes, with on-chip arbitration for up to three external masters in agent mode and full 32-bit/66 MHz operation. In host mode, it generates PCI clocks and manages bus transactions; in agent mode, it responds to configuration and memory-mapped I/O requests. Power management states (D0–D3hot/cold) and PME signaling are fully supported in both configurations.

What is the purpose of the D3warm power state in the MPC8315ECVRAGDA?

The D3warm state is a low-power standby mode where the MPC8315ECVRAGDA powers down the e300c3 core, DDR controller, and most I/O while retaining operation of the Power Management Controller (PMC), one eTSEC, and GTM timer. It enables wake-up via Ethernet magic packet, GPIO, or IRQ within microseconds - ideal for always-on gateways and controllers needing instant responsiveness without full power consumption. Critical supplies like NVDD1_ON remain active; switchable rails (GVDD, VDD) are turned off.
