NXP Semiconductors MPC8315CVRAGDA

Overview

MPC8315CVRAGDA from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture™ e300c3 core, operating at up to 400 MHz with 16 KB instruction and 16 KB data caches, floating-point unit, and MMU support. It integrates dual three-speed Ethernet controllers (10/100/1000 Mbps), DDR1/DDR2 memory controller (up to 266 MHz), dual SATA 3 Gbps interfaces, dual PCI Express x1 lanes, USB 2.0 host/device/OTG controller, and TDM interface - targeting network-attached storage, VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315CVRAGDA datasheet, MPC8315CVRAGDA pinout, MPC8315CVRAGDA application, or MPC8315CVRAGDA equivalent, this page delivers verified technical context, validated package mapping (PBGA-620), confirmed pin functions, real-world use-value in storage and communications systems, and two rigorously cross-checked alternative processors with documented functional and architectural differences.

Technical Context

The MPC8315CVRAGDA 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 SGMII, PCI Express, or SATA PHY modes - but excludes security engine functionality present in the MPC8315E variant.

It features dual independent eTSECs with RGMII/MII/RTBI/SGMII support, a 32-bit PCI interface (66 MHz, 3.3 V only), and a 16-bit enhanced local bus controller (66 MHz). The DDR/DDR2 controller supports 16- or 32-bit width, two chip selects, and auto-refresh - with I/O voltage requirements strictly segregated between GVDD (1.8 V or 2.5 V) and NVDD/LVDD domains.

Key Specifications

Pinout & Package

Packaged in a 27 mm × 27 mm, 620-ball PBGA (Plastic Ball Grid Array) with 1.0 mm ball pitch, RoHS-compliant, and thermally enhanced for industrial temperature operation (0°C to 105°C junction).

Key Features

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar integrated communications processor applications.

Compared with MPC8315EVRAGDA, MPC8315CVRAGDA removes security engine silicon to reduce cost and dynamic power, while retaining identical I/O, memory, and timing capabilities; compared with MPC8377CVRAGDB, it trades CPU speed and PCIe width for integrated SATA and lower thermal envelope - making it optimal for cost-sensitive, storage-centric edge gateways.

Availability

MPC8315CVRAGDA is available at Aetrix Electronics and suitable for network-attached storage, VoIP gateways, and industrial Ethernet controllers requiring stable component supply across extended product lifecycles.

Supply support for MPC8315CVRAGDA 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

NXP Semiconductors is a global semiconductor leader focused on secure connectivity solutions for automotive, industrial, and IoT applications, with deep heritage in Power Architecture™ processor design.

The MPC8315CVRAGDA belongs to the PowerQUICC II Pro family - engineered specifically for cost-optimized, low-power communications infrastructure where integration of Ethernet, SATA, PCIe, and USB into a single SoC reduces system complexity and bill-of-materials cost.

FAQ

Does MPC8315CVRAGDA include a hardware security engine?

No, MPC8315CVRAGDA does not include a security engine. Unlike the MPC8315E variant, this part omits the SEC 3.3 block entirely - meaning AES, SHA, RSA, and HMAC operations must be performed in software on the e300c3 core. The MPC8315CVRAGDA datasheet explicitly states "the MPC8315 do not include a security engine," confirming this is a deliberate product segmentation decision, not a documentation omission.

What is the maximum DDR2 data rate supported by MPC8315CVRAGDA?

MPC8315CVRAGDA supports DDR2 SDRAM at up to 266 MHz data rate (133 MHz clock), corresponding to PC2-4200 bandwidth. This is confirmed in Section 2.4 of the MPC8315EEC datasheet, which specifies "support for up to 266 MHz data rate" for the DDR1/DDR2 memory controller - applicable to MPC8315CVRAGDA as a member of the MPC8315 family.

Is MPC8315CVRAGDA pin-compatible with MPC8315EVRAGDA?

Yes, MPC8315CVRAGDA is pin-compatible with MPC8315EVRAGDA. Both use identical PBGA-620 packaging, share identical ball map, and have functionally equivalent I/O assignments. The sole difference is the absence of SEC-related signals (e.g., SEC_CLK, SEC_RST) in MPC8315CVRAGDA - these balls are NC (no connect) and electrically inert, requiring no PCB change for substitution.

What power supply sequencing is required for reliable MPC8315CVRAGDA startup?

MPC8315CVRAGDA requires strict sequencing: switchable core voltage (VDD) must rise to 90% before switchable I/O voltages (GVDD, LVDDx_OFF, NVDDx_OFF) reach 0.7 V; continuous core (VDDC) must stabilize before continuous I/O (LVDDx_ON, NVDDx_ON). PORESET must remain asserted until ≥32 stable SYS_CLK_IN cycles elapse after all supplies settle - per Figure 3 and Section 3.2 of the MPC8315EEC datasheet.

Can MPC8315CVRAGDA operate in IEEE 1588 Precision Time Protocol mode?

Yes, MPC8315CVRAGDA supports IEEE 1588 PTP timestamping in both eTSEC controllers. The hardware includes dedicated timestamp registers, fine-resolution timers, and frame ingress/egress capture logic - enabling sub-microsecond synchronization accuracy in industrial Ethernet applications, as documented in Section 2.10 and Chapter 20 of the MPC8315EEC reference manual.
