NXP Semiconductors KMPC8349CZUAJDB

Overview

KMPC8349CZUAJDB 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 (TSECs), DDR1/DDR2 memory controller supporting up to 400 MHz data rate and 64-bit interface, and integrated security engine with AES, DES, SHA, RSA, and RNG acceleration - deployed in network-attached storage, industrial gateways, and secure edge routers.

For engineers reviewing the KMPC8349CZUAJDB datasheet, KMPC8349CZUAJDB pinout, KMPC8349CZUAJDB application, or KMPC8349CZUAJDB equivalent, key selection criteria include e300 core frequency headroom, TSEC dual-gigabit MAC timing compliance, DDR2 1.8-V I/O voltage tolerance, PCI 2.3 host/agent mode flexibility, and hardware-accelerated IPSec/SSL offload capability for real-time encrypted throughput.

Technical Context

The KMPC8349CZUAJDB implements a superscalar PowerPC 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, DDR/DDR2 memory controller, and security engine with four crypto-channels.

It supports IEEE 802.3-compliant MII/GMII/RGMII/TBI/RTBI physical layer interfaces per TSEC, programmable DDR/DDR2 timing with ECC, PCI 2.3-compliant dual 32-bit or single 64-bit interfaces, and hardware-enforced coherency across PCI address spaces - all synchronized via integrated PLL/DLL clock generation with 100 μs PLL lock time and DLL lock ranging from 7680–122880 csb_clk cycles.

FAQ

What is the maximum supported DDR2 data rate for KMPC8349CZUAJDB?

KMPC8349CZUAJDB supports DDR2 SDRAM up to 400 MHz data rate (200 MHz clock) in 64-bit configuration. This requires GVDD = 1.8 V ± 90 mV, MVREF = 0.5 × GVDD ± 2%, and DLL lock times between 7680–122880 csb_clk cycles depending on clock ratio. The controller fully supports ECC, registered DIMMs, and self-refresh sleep mode.

Does KMPC8349CZUAJDB support PCI Express?

No, KMPC8349CZUAJDB does not support PCI Express. It implements two PCI 2.3-compliant interfaces - configurable as dual 32-bit or single 64-bit buses operating up to 66 MHz. These are parallel, parallel-signaling PCI interfaces only; no PCIe SerDes, link training, or configuration space extensions are present in the KMPC8349CZUAJDB silicon.

What boot sources are supported by KMPC8349CZUAJDB?

KMPC8349CZUAJDB supports boot from NOR flash via Local Bus (default boot ROM chip select), NAND flash using dedicated NAND controller pins, SPI serial flash, and I2C EEPROM (via I2C-1). Boot mode is selected using CFG_BOOT[0:2] strap pins at reset, and the boot sequencer loads initial code into internal SRAM before jumping to DDR-resident OS.

Is KMPC8349CZUAJDB qualified for industrial temperature range?

Yes, KMPC8349CZUAJDB is rated for operation from –40°C to +105°C junction temperature. This is confirmed in Freescale's MPC8349EA Hardware Specifications Rev. 13, Section 20 (Thermal), and applies to the TBGA package variant (ZUA suffix). Thermal design must maintain TJ ≤ 105°C under worst-case 5 W power dissipation.

How many independent crypto channels does the security engine in KMPC8349CZUAJDB provide?

KMPC8349CZUAJDB's security engine provides four independent crypto channels, each capable of executing multi-command descriptor chains. Each channel can dynamically assign execution units (AESU, DEU, MDEU, PKEU, AFEU) via integrated controller, with 256-byte buffer per unit and flow control for large payloads - enabling concurrent IPSec SA processing and TLS record encryption.
