NXP Semiconductors KMPC8314CVRAGDA

Overview

KMPC8314CVRAGDA 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 enhanced three-speed Ethernet controllers (eTSEC), DDR1/DDR2 memory controller supporting up to 266 MHz data rate, PCI interface up to 66 MHz, and dual PCI Express x1 lanes - targeting network-attached storage (NAS), VoIP gateways, and industrial controllers.

For engineers reviewing the KMPC8314CVRAGDA datasheet, KMPC8314CVRAGDA pinout, KMPC8314CVRAGDA application, or KMPC8314CVRAGDA equivalent, key selection considerations include its 400 MHz e300c3 core performance, dual eTSECs with RGMII/SGMII support, DDR2-266 memory interface, PCI Express 1.0a x1 capability, and absence of integrated security engine - distinguishing it from the MPC8314E variant.

Technical Context

The KMPC8314CVRAGDA implements an e300c3 core derived from MPC603e architecture, featuring two integer units and one FPU, with software compatibility across PowerPC-based Freescale families. Its memory subsystem includes a unified 32-bit DDR1/DDR2 SDRAM controller supporting 16- or 32-bit bus widths, two physical banks, and auto-refresh with CKE-based power management.

Peripheral integration includes dual eTSECs compliant with IEEE 802.3/802.3u/802.3ab/1588, a 32-bit PCI 2.3 controller (3.3 V only), dual PCI Express 1.0a x1 interfaces configurable as root complex or endpoint, USB 2.0 dual-role controller with ULPI/UTMI+ PHY support, and TDM interface supporting up to 128 time slots with 8-/16-bit word width.

Key Specifications

Pinout & Package

The KMPC8314CVRAGDA is housed in a 783-pin PBGA package (35 mm × 35 mm, 1.0 mm pitch), RoHS-compliant, with thermal pad exposed on underside for heatsink mounting. Pin assignments follow Freescale's standardized PowerQUICC II Pro layout, including dedicated banks for DDR, eTSEC, PCI, PCIe, USB, and I/O signals.

Equivalent & Alternatives

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

Compared with MPC8314EVRAGDA, KMPC8314CVRAGDA omits the security engine but retains identical timing, memory, and I/O capabilities - making it suitable for non-crypto workloads. Against MPC8315EVRAGDA, it trades higher CPU speed and SATA for lower BOM cost and power, preserving full software compatibility within the PowerQUICC II Pro family.

FAQ

Does KMPC8314CVRAGDA include an integrated security engine?

No, KMPC8314CVRAGDA does not include a security engine. Unlike the MPC8314E variant, this part omits the SEC 3.3 crypto accelerator. All cryptographic operations - including AES, SHA, RSA, and HMAC - must be performed in software or offloaded to an external security IC. This omission reduces power consumption and cost while maintaining full pin and software compatibility with the MPC8314E family.

What DDR memory types and speeds does KMPC8314CVRAGDA support?

KMPC8314CVRAGDA supports both DDR1 and DDR2 SDRAM via a single 16- or 32-bit interface, with data rates up to 266 MHz (DDR2-533). It accommodates devices from 64 Mbit to 4 Gbit density, with x8/x16 data widths, two independently addressable chip selects, and up to 16 open pages. The controller supports auto-refresh, CKE-based power-down, and 1.8 V (DDR2) or 2.5 V (DDR1) SSTL2-compatible I/O.

Can KMPC8314CVRAGDA operate in PCI Express endpoint mode?

Yes, KMPC8314CVRAGDA supports configurable PCI Express operation: each of its two x1 lanes can be independently set as root complex or endpoint. This enables flexible system topologies - for example, one lane as root connecting to a SATA controller, and the other as endpoint for a custom FPGA co-processor. Configuration is done via boot-time strap pins and RCW settings, with full MSI and INTx interrupt support.

What is the maximum operating temperature for KMPC8314CVRAGDA?

KMPC8314CVRAGDA is rated for a junction temperature range of 0 °C to 105 °C, per its Freescale specification. Thermal design must ensure the die temperature stays within this limit under worst-case load - especially during sustained 400 MHz core operation with dual eTSECs and DDR2-266 active. The exposed thermal pad on the 783-pin PBGA package must be soldered to a solid copper plane and optionally coupled to a heatsink.

Is KMPC8314CVRAGDA pin-compatible with MPC8314EVRAGDA?

Yes, KMPC8314CVRAGDA is fully pin-compatible with MPC8314EVRAGDA - sharing identical 783-pin PBGA mechanical dimensions, pin functions, power domains, and signal timing. The only functional difference is the absence of the security engine in KMPC8314CVRAGDA. PCB layouts designed for MPC8314EVRAGDA can use KMPC8314CVRAGDA without modification, provided software does not invoke SEC registers.
