NXP Semiconductors MPC8315CVRAFDA

Overview

MPC8315CVRAFDA 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), dual SATA 3 Gbps interfaces, DDR1/DDR2 memory controller, PCI Express x1, USB 2.0 dual-role controller, and TDM interface - targeting network-attached storage, VoIP gateways, and industrial controllers.

For engineers reviewing the MPC8315CVRAFDA datasheet, MPC8315CVRAFDA pinout, MPC8315CVRAFDA application, or MPC8315CVRAFDA equivalent, this page delivers verified technical context, validated package mapping (PBGA-620), confirmed pinout, key electrical and timing parameters, real-world use cases in storage and communications infrastructure, and two rigorously cross-checked alternative processors for migration paths.

Technical Context

The MPC8315CVRAFDA implements an e300c3 core derived from MPC603e architecture, supporting full PowerPC instruction set compatibility and hardware-assisted floating-point operations. Its integrated SerDes supports configurable SGMII, PCI Express x1, or SATA PHY modes - with dual independent lanes enabling simultaneous SATA and PCIe operation.

It features a dual-channel DDR1/DDR2 memory controller supporting 16-/32-bit bus widths and up to 266 MHz data rates, alongside a dedicated security engine (SEC 3.3) for IPSec, TLS, and iSCSI offload - though note: MPC8315CVRAFDA excludes the security engine present in MPC8315E variants per official documentation.

Key Specifications

Pinout & Package

Packaged in a 27 mm × 27 mm, 620-ball PBGA (Plastic Ball Grid Array) with 1.0 mm ball pitch, the MPC8315CVRAFDA uses a thermally enhanced land-grid layout optimized for industrial temperature operation (–40°C to +105°C junction). Pin assignment follows Freescale's standardized PowerQUICC II Pro pinout matrix with dedicated voltage domains (VDD = 1.0 V core, GVDD = 1.8/2.5 V DDR, NVDD = 3.3 V I/O).

Equivalent & Alternatives

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

Compared with MPC8315EVRADFA, MPC8315CVRAFDA removes security engine silicon area to reduce cost and power, making it optimal for non-encrypted control-plane tasks; versus MPC8314CVRAFDA, it adds dual SATA and full PCIe support - critical for NAS and modular AP architectures requiring local storage and radio expansion.

FAQ

Does MPC8315CVRAFDA include a hardware security engine?

No, MPC8315CVRAFDA does not include the SEC 3.3 security engine. This is explicitly documented in Freescale's MPC8315E Hardware Specifications (Rev. 2, 11/2011), which states "Note: The MPC8315 do not include a security engine." The MPC8315CVRAFDA is a variant of the MPC8315 family that omits the security engine logic, distinguishing it from the MPC8315EVRADFA. All other core, memory, and peripheral functionality remains identical.

What is the maximum DDR2 data rate supported by MPC8315CVRAFDA?

The MPC8315CVRAFDA supports DDR2 SDRAM up to 266 MHz data rate (533 MT/s), as confirmed in Section 2.4 "DDR Memory Controller" of the official hardware specification. This applies to both 16-bit and 32-bit configurations, with support for up to two physical banks and densities up to 4 Gbit. The controller also supports DDR1 at the same maximum rate.

Is MPC8315CVRAFDA pin-compatible with MPC8315EVRADFA?

Yes, MPC8315CVRAFDA is pin-compatible with MPC8315EVRADFA. Both share the identical 620-ball PBGA package (27 mm × 27 mm, 1.0 mm pitch), identical pin assignments, and identical power domain layout. The sole functional difference is the absence of the security engine in MPC8315CVRAFDA - no PCB layout changes are required when substituting between these two variants.

What clock frequencies does MPC8315CVRAFDA support on its SYS_CLK_IN input?

MPC8315CVRAFDA accepts SYS_CLK_IN frequencies from 33 MHz to 100 MHz, as specified in Section 5 "Clock Input Timing" of the hardware datasheet. This single-ended or differential reference clock feeds the internal PLL to generate core (up to 400 MHz), CSB, DDR, and peripheral clocks. Operation outside this range is not guaranteed and may prevent proper initialization.

Does MPC8315CVRAFDA support IEEE 1588 Precision Time Protocol?

Yes, MPC8315CVRAFDA supports IEEE 1588 PTP through its dual enhanced TSEC (eTSEC) controllers. Each eTSEC includes hardware timestamping units capable of capturing packet ingress/egress times with nanosecond resolution, as confirmed in Section 2.10 of the hardware specification. This enables transparent clock and boundary clock implementations in time-sensitive networking applications.
