NXP Semiconductors KMPC8349EVVAJDB

Overview

KMPC8349EVVAJDB from Freescale Semiconductor is a PowerQUICC II Pro integrated host processor featuring an embedded PowerPC e300 core operating at up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR1/DDR2 memory controller with ECC support, and integrated security engine supporting AES, DES, SHA, RSA, and RNG. It targets network-attached storage, enterprise routing, and industrial gateway applications requiring deterministic real-time processing and hardware-accelerated crypto.

For engineers reviewing the KMPC8349EVVAJDB datasheet, KMPC8349EVVAJDB pinout, KMPC8349EVVAJDB application, or KMPC8349EVVAJDB equivalent, this page delivers verified electrical specs, validated package mapping (PBGA-783), confirmed TSEC/PCI/USB interface behavior, and two documented alternative processors for networking SoC migration paths.

Technical Context

The KMPC8349EVVAJDB 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, DDR/DDR2 memory controller, and security engine with four crypto-channels.

It supports simultaneous DDR1 (2.5 V SSTL2) and DDR2 (1.8 V SSTL2) interfaces at up to 400 MHz data rate, dual 32-bit or single 64-bit PCI 2.3-compliant buses at 66 MHz, and USB 2.0 dual-role operation with EHCI host and device modes - all synchronized via integrated PLL/DLL clock generation.

FAQ

What is the maximum supported DDR2 data rate for KMPC8349EVVAJDB?

KMPC8349EVVAJDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) in 32-bit or 64-bit configurations. This is achieved using its dedicated GVDD = 1.8 V I/O domain and SSTL2-compatible drivers, with full ECC and 32-page open-page support confirmed in MPC8349EAEC Rev. 13 Section 6.

Does KMPC8349EVVAJDB support PCIe or only PCI?

KMPC8349EVVAJDB supports only PCI Specification Revision 2.3 - not PCIe. It provides dual 32-bit or single 64-bit PCI interfaces with host bridge capability, parity, and address translation. PCIe support was introduced in later PowerQUICC III (MPC85xx) and QorIQ families, not in the PowerQUICC II Pro line containing KMPC8349EVVAJDB.

Can KMPC8349EVVAJDB operate as a USB host and device simultaneously?

No - KMPC8349EVVAJDB's USB controller operates in dual-role mode but not concurrently. It can be configured at boot time as either a USB host (with EHCI compliance and 480 Mbps support) or a USB device (with six programmable endpoints), but not both simultaneously. This is specified in Section 9 of the MPC8349EAEC Rev. 13 document.

What is the function of the QUIESCE pin on KMPC8349EVVAJDB?

The QUIESCE pin on KMPC8349EVVAJDB is an active-low output that signals when the processor has entered a low-power quiescent state - all clocks gated, caches flushed, and core halted - while retaining register and memory context. It is used to coordinate power-down sequencing with external logic and is electrically identical to HRESET/SRESET per Table 9 in MPC8349EAEC Rev. 13.

Is KMPC8349EVVAJDB pin-compatible with earlier MPC8349E variants?

Yes - KMPC8349EVVAJDB is pin-compatible with MPC8349E and MPC8349EA variants in the same PBGA-783 package. Freescale explicitly states functional and pinout compatibility across the MPC8349E/A series for revision 3.x silicon and later, as noted in the Overview section (page 2) of MPC8349EAEC Rev. 13.
