NXP Semiconductors MPC8349ECVVAJFB

Overview

MPC8349ECVVAJFB 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 (TSECs), 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, enterprise routers, and industrial gateways requiring deterministic real-time processing and hardware crypto offload.

For engineers reviewing the MPC8349ECVVAJFB datasheet, MPC8349ECVVAJFB pinout, MPC8349ECVVAJFB application, or MPC8349ECVVAJFB equivalent, key selection considerations include its 667-MHz e300 core performance, dual TSEC gigabit Ethernet interfaces with RGMII/TBI support, DDR2-400 64-bit memory controller, PCI 2.3-compliant dual bus architecture, and hardware-accelerated AES/SHA/RSA crypto engine - all in a 620-pin TBGA package rated for industrial temperature range.

Technical Context

The MPC8349ECVVAJFB 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, DDR2 SDRAM controller, and security engine with four crypto-channels supporting concurrent AES-256, SHA-256, RSA-2048, and DES/3DES operations.

It integrates dual independent PCI interfaces (32-bit/66 MHz or 64-bit/66 MHz), a local bus controller with eight chip selects and programmable UPM engines, dual USB 2.0 controllers (one OTG-capable), and dual I²C, DUART, SPI, GPIO, and JTAG interfaces - all synchronized via on-chip PLL/DLL clock generation with configurable reset sequencing and power-up voltage tracking requirements.

FAQ

What is the maximum DDR2 data rate supported by the MPC8349ECVVAJFB?

The MPC8349ECVVAJFB supports DDR2 SDRAM at up to 400 MHz data rate (200 MHz clock) on a 64-bit interface, delivering theoretical peak bandwidth of 6.4 GB/s. This is confirmed in Section 6 of the MPC8349EAEC Rev. 13 datasheet, which specifies programmable timing for DDR2-400 operation with full ECC and registered DIMM support. The MPC8349ECVVAJFB achieves this using its dedicated DDR2 I/O bank with 1.8-V SSTL2-compatible signaling and DLL-based write leveling.

Does the MPC8349ECVVAJFB support PCIe or only legacy PCI?

The MPC8349ECVVAJFB supports only PCI Specification Revision 2.3 - not PCIe. It features two fully compliant 32-bit/66 MHz PCI interfaces (or one 64-bit/66 MHz interface), with host bridge capabilities on both and agent mode on PCI1. There is no native PCIe root complex or endpoint functionality; PCIe compatibility would require an external bridge IC. This limitation is explicitly stated in Section 13 "PCI" of the MPC8349EAEC Rev. 13 hardware specifications.

What crypto algorithms are accelerated in hardware by the MPC8349ECVVAJFB security engine?

The MPC8349ECVVAJFB security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), SHA-1/224/256, MD5, HMAC-SHA/MD5, RSA-2048, Diffie-Hellman, elliptic curve cryptography (F_p/F_2m), DES/3DES (ECB/CBC), and RC4. These are implemented across dedicated execution units (AESU, MDEU, PKEU, DEU, AFEU) with four independent crypto-channels, as detailed in Section 1 "Overview" and Appendix A of the MPC8349EAEC Rev. 13 datasheet.

Can the MPC8349ECVVAJFB operate with DDR1 and DDR2 memory simultaneously?

No, the MPC8349ECVVAJFB cannot operate DDR1 and DDR2 memory simultaneously. Its DDR controller supports either DDR1 (2.5-V SSTL2) or DDR2 (1.8-V SSTL2) in a given design, selected at boot time via configuration pins and register settings. The GVDD supply must be set to 2.5 V for DDR1 or 1.8 V for DDR2 - mixing voltages risks damage and violates the absolute maximum ratings in Table 1 of the MPC8349EAEC Rev. 13 datasheet.

What is the industrial temperature rating for the MPC8349ECVVAJFB?

The MPC8349ECVVAJFB is rated for industrial temperature operation from –40°C to +105°C, as specified in Section 20 "Thermal" of the MPC8349EAEC Rev. 13 datasheet. This rating applies to the CVVAJFB suffix variant, which uses a 620-pin TBGA package with exposed thermal pad and is qualified for continuous operation under these conditions when mounted with appropriate heatsinking and airflow per JEDEC JESD51 standards.
