NXP Semiconductors KMPC8349ECVVAJDB

Overview

KMPC8349ECVVAJDB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR1/DDR2 memory controller with ECC support, and integrated security engine for IPSec/SSL acceleration. It targets network edge routers, industrial gateways, and secure embedded communications systems requiring high-throughput packet processing and hardware crypto offload.

For engineers reviewing the KMPC8349ECVVAJDB datasheet, KMPC8349ECVVAJDB pinout, KMPC8349ECVVAJDB application, or KMPC8349ECVVAJDB equivalent, this page delivers verified electrical specs (1.3 V core, 2.5 V/1.8 V DDR I/O), thermal power data (5 W max at 667 MHz), PCI 2.3 compliance, and confirmed TSEC/GMII/RGMII interface timing - all validated against Freescale MPC8349EAEC Rev. 13 documentation.

Technical Context

The KMPC8349ECVVAJDB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, dynamic power management, and software compatibility across Power Architecture families. Its coherent system bus interconnects dual TSECs, PCI controllers, USB 2.0 host/device, and a security engine with four crypto-channels supporting AES-256, SHA-256, RSA-2048, and DES/3DES.

Memory subsystem includes a programmable DDR/DDR2 SDRAM controller with 32-/64-bit interface, up to 400 MHz data rate, four physical banks (1 Gbyte each), full ECC, and registered DIMM support. Dual PCI interfaces operate at 32-bit/66 MHz or combined 64-bit/66 MHz with parity, coherency enforcement, and address translation units.

FAQ

What is the maximum supported DDR2 data rate for KMPC8349ECVVAJDB?

KMPC8349ECVVAJDB supports DDR2 SDRAM up to 400 MHz data rate (200 MHz clock) on its 32-bit or 64-bit interface. This is confirmed in Section 6 of the MPC8349EAEC Rev. 13 specification, which states "up to 400 MHz data rate" for both DDR1 and DDR2 modes. The controller achieves this using programmable timing parameters and supports registered DIMMs for stable high-speed operation.

Does KMPC8349ECVVAJDB support PCIe or only legacy PCI?

KMPC8349ECVVAJDB supports only PCI Specification Revision 2.3 - not PCIe. Its dual PCI interfaces operate at 32-bit/66 MHz or combined 64-bit/66 MHz with parity, coherency enforcement, and address translation. The documentation makes no reference to PCIe signaling, lanes, or configuration space; all PCI-related sections (Section 13) explicitly cite PCI Rev. 2.3 compliance.

What are the power sequencing requirements for KMPC8349ECVVAJDB?

KMPC8349ECVVAJDB requires VDD (core) to reach 90% of nominal value before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V, per Figure 4 in the MPC8349EAEC Rev. 13 spec. Failure to follow this sequence risks 3–5 A contention current. PORESET must be asserted before power ramp completion to prevent spurious I/O driving during unstable conditions.

Is KMPC8349ECVVAJDB pin-compatible with earlier MPC8349E variants?

KMPC8349ECVVAJDB is not pin-compatible with MPC8349E (non-"A" revision). Section 1 of the MPC8349EAEC Rev. 13 document states it applies only to "revision 3.x silicon and later (orderable part numbers ending in A or B)", and notes functional differences including DDR2 support, enhanced security engine, and updated PLL/DLL lock times absent in pre-A silicon.

What USB modes does KMPC8349ECVVAJDB support according to its official specification?

KMPC8349ECVVAJDB supports USB 2.0 On-The-Go (OTG) mode with both host and device functionality, as stated in Section 5 of the MPC8349EAEC Rev. 13 document. It includes EHCI-compatible host mode (480 Mbps), device mode with six endpoints, and external PHY interfaces via UTMI+, serial, and ULPI - enabling flexible peripheral or host role selection in field-deployable systems.
