NXP Semiconductors KMPC8315CVRAGDA

Overview

KMPC8315CVRAGDA from NXP Semiconductors (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 (up to 266 MHz), PCI interface (32-bit, 66 MHz), and USB 2.0 dual-role controller - targeting network-attached storage, VoIP gateways, and industrial controllers.

For engineers reviewing the KMPC8315CVRAGDA datasheet, KMPC8315CVRAGDA pinout, KMPC8315CVRAGDA application, or KMPC8315CVRAGDA equivalent, key selection considerations include its e300c3 core performance, dual SATA 3 Gbps support, absence of security engine (vs. MPC8315E), 672-pin PBGA package, and compatibility with PowerQUICC II Pro software ecosystem for NAS and embedded networking designs.

Technical Context

The KMPC8315CVRAGDA implements an e300c3 core derived from MPC603e architecture, featuring two integer units, one FPU, and full PowerPC ISA compliance. Its SoC integration includes dual eTSECs supporting RGMII/SGMII/MII/RTBI, a 32-bit PCI controller compliant with Revision 2.3, and a DDR1/DDR2 SDRAM controller supporting 16-/32-bit buses at up to 266 MHz data rate.

Unlike the MPC8315E, KMPC8315CVRAGDA omits the SEC 3.3 security engine and associated cryptographic accelerators (AESU, MDEU, PKEU). It retains dual SATA 3 Gbps controllers, dual PCI Express x1 lanes (PCIe 1.0a), TDM interface, USB 2.0 UTMI+/ULPI PHY, and IPIC interrupt controller - all configured via dedicated configuration registers and boot-time strap options.

Key Specifications

Pinout & Package

KMPC8315CVRAGDA is housed in a 672-ball plastic ball grid array (PBGA) package with 1.0 mm ball pitch, thermal pad exposed on underside, and JEDEC-standard mechanical dimensions (35 mm × 35 mm). The package supports lead-free assembly and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3.

Applications

Equivalent & Alternatives

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

Compared with MPC8315EVRAGDA, KMPC8315CVRAGDA removes security acceleration but retains identical I/O, timing, and software compatibility - making it ideal for non-secure storage or industrial control. Against MPC8377CVRAGDB, it trades higher CPU speed and PCIe lanes for lower cost, smaller footprint, and integrated SATA - prioritizing storage interface density over raw compute.

KMPC8315CVRAGDA belongs to the PowerQUICC II Pro family, designed specifically for cost-sensitive, low-power embedded networking and storage applications where integration of Ethernet, SATA, DDR, and PCI interfaces reduces system complexity and bill-of-materials cost.

FAQ

Does KMPC8315CVRAGDA include a security engine?

No, KMPC8315CVRAGDA does not include the SEC 3.3 security engine. This distinguishes it from the MPC8315E variant, which integrates AESU, MDEU, PKEU, and RNG accelerators. KMPC8315CVRAGDA relies on software-based cryptography or external security ICs for encryption, authentication, and random number generation - reducing silicon cost and power consumption where hardware security is not required.

What is the maximum DDR2 data rate supported by KMPC8315CVRAGDA?

KMPC8315CVRAGDA supports DDR2 SDRAM at up to 266 MHz data rate (533 MT/s), with 1.8 V ±100 mV GVDD supply and compatible 16-/32-bit bus widths. The controller supports up to two physical banks, 16 simultaneous open pages, and auto-refresh - enabling efficient buffering for streaming media or packet processing in NAS and gateway applications.

Is KMPC8315CVRAGDA pin-compatible with MPC8315EVRAGDA?

Yes, KMPC8315CVRAGDA is pin-compatible with MPC8315EVRAGDA in the same 672-pin PBGA package. All signal names, power domains, and mechanical dimensions match exactly. The only functional difference is the absence of the security engine block in KMPC8315CVRAGDA - meaning no changes to PCB layout, power delivery, or signal routing are needed when substituting between these two variants.

What clock frequencies does KMPC8315CVRAGDA support for its eTSEC Ethernet interfaces?

KMPC8315CVRAGDA eTSEC interfaces support RGMII at 125 MHz (for 1000 Mbps), MII at 25 MHz (for 10/100 Mbps), and SGMII at 1.25 GHz (via SerDes). Clock sourcing is flexible: SYS_CLK_IN can drive both eTSECs directly, or separate clocks may be applied via RTBI/SGMII PHY interfaces - enabling mixed-speed deployments such as 1 Gbps WAN + 100 Mbps LAN on the same SoC.

How does KMPC8315CVRAGDA handle power management in low-power states?

KMPC8315CVRAGDA implements PCI Power Management 1.2 states (D0–D3hot) plus a proprietary D3warm state. In D3warm, only PMC, one eTSEC, and GTM remain powered via split supply; wake events include Magic Packet™, GPIO, or IRQ inputs. Core voltage (VDDC) stays active while switchable supplies (VDD, GVDD, LVDDx_OFF) are shut down - achieving ~30% lower quiescent power than full D3cold while retaining fast resume capability.
