NXP Semiconductors MPC8349EZUALFB

Overview

MPC8349EZUALFB 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 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 MPC8349EZUALFB datasheet, MPC8349EZUALFB pinout, MPC8349EZUALFB application, or MPC8349EZUALFB 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's MPC8349EAEC Rev. 13 hardware specification.

Technical Context

The MPC8349EZUALFB implements a superscalar e300 core with 32-Kbyte L1 instruction and data caches, lockable cache segments, and dynamic power management. Its coherent system bus interconnects dual TSECs, PCI controllers (32-bit/66 MHz or 64-bit/66 MHz), DDR/DDR2 memory controller, and security engine with four crypto-channels.

It integrates dedicated hardware accelerators including AESU (128/192/256-bit keys), DES/3DES, SHA-1/224/256, MD5, RSA up to 2048-bit, and RNG - all accessible via descriptor-based DMA. Clocking supports CLKIN or PCI_SYNC_IN primary inputs with ±150 ps jitter tolerance and DLL lock times ranging from 7680 to 122,880 csb_clk cycles.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349EZUALFB?

The MPC8349EZUALFB supports DDR2 SDRAM up to 400 MHz data rate (200 MHz clock) on a 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 DDR1/DDR2 operation. The MPC8349EZUALFB implements this capability using its dedicated GVDD = 1.8 V I/O domain and programmable timing registers.

Does the MPC8349EZUALFB support PCIe?

No, the MPC8349EZUALFB does not support PCIe. It features two legacy PCI 2.3-compliant interfaces - one configurable as 64-bit/66 MHz host bridge and the other as 32-bit/66 MHz agent - but lacks PCIe physical layer, transaction layer, or configuration space. This is explicitly stated in the "Dual PCI interfaces" feature list and confirmed by absence of PCIe terminology throughout the MPC8349EAEC Rev. 13 document.

What are the voltage requirements for the MPC8349EZUALFB core and I/O supplies?

The MPC8349EZUALFB requires VDD = 1.3 V ±60 mV for 667 MHz operation, AVDD = 1.3 V ±60 mV for PLL, GVDD = 2.5 V ±125 mV (DDR1) or 1.8 V ±90 mV (DDR2), LVDD = 3.3 V ±330 mV or 2.5 V ±125 mV (Ethernet), and OVDD = 3.3 V ±330 mV (PCI/local bus). All supplies must track directionally per Table 2 of MPC8349EAEC Rev. 13.

Is the MPC8349EZUALFB pin-compatible with the MPC8349E?

No, the MPC8349EZUALFB is not pin-compatible with earlier MPC8349E revisions. Freescale documentation specifies that silicon revision 3.x and later (denoted by part numbers ending in 'A' or 'B') introduced changes to pin functionality and electrical characteristics. The MPC8349EZUALFB is a revision 'B' part and requires layout validation against the 676-pin TBGA pinout in Section 18 of MPC8349EAEC Rev. 13.

What boot sources are supported by the MPC8349EZUALFB?

The MPC8349EZUALFB supports boot from NOR flash via its Local Bus Controller (LBC) with configurable 8-/16-/32-bit bus width, SPI serial flash (via SPI controller), I2C EEPROM (using I2C-1 interface), and NAND flash (with external controller). Boot configuration is controlled by CFG_RESET_SOURCE[0:2] pins and documented in Section 21 of MPC8349EAEC Rev. 13.
