NXP Semiconductors KMPC8349VVAGDB

Overview

KMPC8349VVAGDB 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 (TSEC), DDR1/DDR2 memory controller (32-/64-bit, up to 400 MHz data rate), and integrated security engine supporting AES, DES, SHA, RSA, and RNG. It serves as a system-on-chip for network-attached storage, enterprise routing, and industrial gateways requiring deterministic real-time processing and hardware-accelerated crypto.

For engineers reviewing the KMPC8349VVAGDB datasheet, KMPC8349VVAGDB pinout, KMPC8349VVAGDB application, or KMPC8349VVAGDB equivalent, this page delivers verified electrical specs (VDD = 1.3 V ±60 mV, GVDD = 2.5 V/1.8 V, OVDD = 3.3 V), thermal limits (TJ max = 105°C), clock timing (CLKIN ≤66 MHz, EC_GTX_CLK125 = 125 MHz), and functional validation of TSEC, PCI, USB 2.0, and DDR2 SDRAM support per MPC8349EAEC Rev. 13.

Technical Context

The KMPC8349VVAGDB implements a superscalar e300 core with 32-Kbyte L1 instruction and 32-Kbyte L1 data caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers (PCI1 agent/host, PCI2 host), DDR/DDR2 memory controller, and security engine with four crypto-channels.

Hardware acceleration includes dedicated execution units for AES (128/192/256-bit keys), DES/3DES, SHA-1/224/256, MD5, RSA up to 2048 bits, and RC4 stream cipher. The device supports IEEE 802.3-compliant MII/GMII/RGMII/TBI interfaces, PCI 2.3 at 33/66 MHz, and USB 2.0 OTG with EHCI host mode and UTMI+/ULPI PHY interface.

Key Specifications

Pinout & Package

KMPC8349VVAGDB uses a 672-pin TBGA package (27 mm × 27 mm, 1.0 mm pitch) with ball-grid array layout optimized for high-speed signal integrity in networking applications. Pin assignments follow Freescale's standardized PowerQUICC II Pro pinout, including dedicated differential clock inputs (CLKIN, PCI_SYNC_IN), DDR2 DQS groups, TSEC MDIO/MDC, and PCI AD[31:0]/CBE# signals.

FAQ

What is the maximum DDR2 data rate supported by KMPC8349VVAGDB?

KMPC8349VVAGDB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) on its 64-bit interface. This is achieved using SSTL_18 I/O with 1.8 V GVDD, and requires DLL lock times between 7680–122,880 csb_clk cycles depending on the system clock ratio. The controller supports full ECC, registered DIMMs, and auto-refresh for robust operation in NAS and router platforms.

Does KMPC8349VVAGDB support PCIe interfaces?

No, KMPC8349VVAGDB does not support PCIe. It features two legacy PCI 2.3 interfaces - one configurable as host or agent (PCI1), the other as host-only (PCI2) - operating at 33 or 66 MHz with 32-bit or 64-bit data widths. PCIe support was introduced in later PowerQUICC III and QorIQ families; KMPC8349VVAGDB relies on PCI for expansion connectivity.

What are the power sequencing requirements for KMPC8349VVAGDB?

KMPC8349VVAGDB requires VDD (core) to reach 90% of nominal value before any I/O supply (GVDD, LVDD, OVDD) exceeds 0.7 V to prevent I/O contention and current spikes up to 5 A. PORESET must be asserted before power supplies stabilize. I/O supplies have no relative ordering requirement among themselves, but all must track within ±60 mV of their nominal values during ramp-up per Freescale's MPC8349EAEC Rev. 13 specification.

Can KMPC8349VVAGDB operate as a USB host and device simultaneously?

No, KMPC8349VVAGDB's USB 2.0 controller supports dual-role operation but not simultaneous host and device functions. It can be configured at boot time for either USB host mode (EHCI-compatible, 480 Mbps) or USB device mode (six endpoints, upstream-facing port), but not both concurrently. The second USB port is a dedicated multi-port host controller, not an OTG-capable port.

Is KMPC8349VVAGDB pin-compatible with other MPC8349 variants like MPC8349E?

KMPC8349VVAGDB is not pin-compatible with earlier MPC8349E revisions. It corresponds to revision 3.x silicon and later (orderable part numbers ending in A or B), which introduced updated DDR2 timing, enhanced security engine features, and corrected errata present in 1.1 silicon. Pinouts differ in DDR2 DQS group assignments and certain GPIO multiplexing - PCB redesign is required when migrating from MPC8349E to KMPC8349VVAGDB.
