NXP Semiconductors KMPC8379EVRALG

Overview

KMPC8379EVRALG from Freescale Semiconductor is a PowerQUICC II Pro communications processor featuring the e300c4s Power Architecture® core (667 MHz), dual enhanced three-speed Ethernet controllers (10/100/1000 Mbps), DDR1/DDR2 SDRAM controller (up to 400 MHz data rate), optional SEC 3.0 security engine, and four SATA 2.5 interfaces - deployed as main CPU in industrial controllers, network access servers, and intelligent NICs.

For engineers reviewing the KMPC8379EVRALG datasheet, KMPC8379EVRALG pinout, KMPC8379EVRALG application, or KMPC8379EVRALG equivalent, this page delivers verified electrical specs (VDD = 1.0 ± 0.05 V @ 667 MHz), thermal limits (Tj = 125°C), I/O voltage domains (LVDD = 2.5/3.3 V, GVDD = 1.8/2.5 V), SATA 3.0 Gb/s support, and eTSEC IEEE 1588™ compliance - all confirmed against Freescale MPC8379EEC Rev. 8.

Technical Context

The KMPC8379EVRALG integrates an e300c4s core with 32 KB L1 instruction and 32 KB L1 data caches, floating-point unit, and dual integer units - operating at up to 667 MHz with core supply VDD = 1.0 ± 50 mV. Its DDR1/DDR2 memory controller supports 32-/64-bit interfaces, 4 chip selects, and auto-refresh with CKE-based power management.

Two eTSECs implement IEEE 802.3, 802.3u, 802.3ab, and IEEE 1588™ for precision time synchronization; each supports RGMII, RMII, MII, and RTBI PHY interfaces. The optional SEC 3.0 security engine offloads DES/3DES/AES/SHA-1/MD-5 operations via one crypto-channel and dedicated execution units.

FAQ

What is the maximum DDR2 data rate supported by KMPC8379EVRALG?

KMPC8379EVRALG supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) with GVDD = 1.8 V ± 90 mV. This enables peak theoretical bandwidth of 6.4 GB/s on a 64-bit interface. The controller supports 4 chip selects and up to 32 simultaneous open pages, validated per Freescale MPC8379EEC Rev. 8 Section 1.1.

Does KMPC8379EVRALG include hardware support for IEEE 1588™ Precision Time Protocol?

Yes, KMPC8379EVRALG includes full hardware timestamping capability in both eTSEC controllers per IEEE Std 1588™-2008. Each eTSEC provides nanosecond-resolution timestamp registers for transmit and receive packets, enabling sub-microsecond synchronization accuracy in industrial control and telecom timing applications as documented in Section 1.3 of MPC8379EEC Rev. 8.

What are the power supply sequencing requirements for KMPC8379EVRALG?

KMPC8379EVRALG requires VDD and AVDD to reach 90% of nominal value before GVDD, LVDD, or OVDD rise above 10% - per Figure 3 in MPC8379EEC Rev. 8. Failure to observe this sequence risks I/O contention and excessive current draw. SerDes supply L[1,2]_nVDD must follow VDD timing. No specific shutdown order is mandated.

How many SATA interfaces does KMPC8379EVRALG provide, and what revision do they implement?

KMPC8379EVRALG integrates four independent Serial ATA controllers compliant with SATA Rev 2.5 specification, supporting 1.5 Gb/s and 3.0 Gb/s operation, native command queuing, hot plug, and staggered spin-up - as confirmed in Table 1 and Section 1.10 of MPC8379EEC Rev. 8.

Is the security engine in KMPC8379EVRALG optional or integrated?

The security engine in KMPC8379EVRALG is optional but physically present - denoted by the "E" suffix in the part number. It implements SEC 3.0 with dedicated DEU, AESU, and MDEU execution units for DES/3DES, AES, and SHA-1/MD-5, enabling offload of IPSec and 802.11i processing without CPU intervention per Section 1.8 of MPC8379EEC Rev. 8.
