Overview

KMPC8349EVVALFB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor built on Power Architecture® technology, featuring an e300 core operating up to 667 MHz, dual 10/100/1000-Mbps Ethernet controllers (TSECs), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration. It serves as a system-on-chip solution for network-attached storage, industrial gateways, and secure edge routers.

For engineers reviewing the KMPC8349EVVALFB datasheet, KMPC8349EVVALFB pinout, KMPC8349EVVALFB application, or KMPC8349EVVALFB equivalent, key selection considerations include its 667-MHz e300 core performance, dual TSEC compliance with IEEE 802.3z/802.3ac, DDR2-400 support at 1.8 V, PCI 2.3 host/agent dual interface capability, and hardware-accelerated AES-256/SHA-256 crypto processing.

Technical Context

The KMPC8349EVVALFB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, dynamic power management, and software compatibility across Freescale's Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI controllers, USB 2.0 host/device, and security engine crypto-channels.

It integrates a programmable DDR/DDR2 SDRAM controller supporting 32-/64-bit interfaces up to 400 MHz, four physical banks, and full ECC; dual PCI interfaces compliant with Revision 2.3-configurable as two 32-bit buses or one 64-bit bus-and a security engine with dedicated PKEU, AESU, MDEU, and RNG units for concurrent cryptographic operations.

FAQ

What is the maximum DDR2 data rate supported by KMPC8349EVVALFB?

KMPC8349EVVALFB supports DDR2 data rates up to 400 MHz (DDR2-400), delivering up to 6.4 GB/s bandwidth on a 64-bit interface. This is confirmed in Section 6 of the MPC8349EAEC Rev. 13 specification, which specifies programmable timing for DDR2 SDRAM with 1.8-V SSTL2-compatible I/O and support for registered DIMMs. The KMPC8349EVVALFB achieves this using its integrated DDR2 memory controller with ECC and 16 open-page capability.

Does KMPC8349EVVALFB include hardware acceleration for TLS/SSL protocols?

Yes, KMPC8349EVVALFB includes a dedicated security engine with AESU (supporting AES-128/192/256 in ECB/CBC/CTR/CCM modes), MDEU (SHA-1/224/256 and MD5), and RNG - all explicitly cited in the Overview section of MPC8349EAEC Rev. 13 as optimized for SSL/TLS and IPSec processing. The KMPC8349EVVALFB uses four crypto-channels to execute these algorithms concurrently, offloading the e300 core.

What are the power sequencing requirements for KMPC8349EVVALFB?

KMPC8349EVVALFB requires VDD (core) to be applied before GVDD/LVDD/OVDD (I/O supplies) to prevent excessive current draw (3–5 A) during ramp-up. Per Section 2.2.1 of MPC8349EAEC Rev. 13, VDD must reach 90% of nominal value before any I/O rail exceeds 0.7 V, and PORESET must be asserted before full voltage stabilization. The KMPC8349EVVALFB datasheet defines absolute max ratings and recommended operating conditions for each supply domain, including tracking requirements.

Can KMPC8349EVVALFB operate in PCI agent mode?

Yes, KMPC8349EVVALFB supports PCI agent mode on the PCI1 interface, as documented in Section 13 ("PCI") of MPC8349EAEC Rev. 13. In this mode, the device acts as a peripheral responding to PCI bus master transactions, with PCI_SYNC_IN serving as the primary clock source. The KMPC8349EVVALFB also supports PCI host bridge functionality on both PCI1 and PCI2, enabling flexible system topology design.

What packaging and thermal characteristics apply to KMPC8349EVVALFB?

KMPC8349EVVALFB uses a 689-ball TBGA package (27 mm × 27 mm, 1.0 mm pitch) with thermal lid and exposed paddle, specified in Section 18 of MPC8349EAEC Rev. 13. Thermal resistance θJA is 12.5°C/W (typical) at 667 MHz, and maximum junction temperature is 105°C. The KMPC8349EVVALFB requires a 4-layer PCB with dedicated ground/power planes and thermal vias under the exposed paddle for reliable operation at full speed.
