NXP Semiconductors MPC8347CVRAGDB

Overview

MPC8347CVRAGDB from NXP (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor built on Power Architecture™ technology, featuring an e300 core operating up to 533 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 333 MHz data rate in TBGA package, and integrated security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347CVRAGDB datasheet, MPC8347CVRAGDB pinout, MPC8347CVRAGDB application, or MPC8347CVRAGDB equivalent, key selection criteria include its 533 MHz e300 core frequency, TBGA-783 package with 783-ball grid array, DDR-1 SDRAM interface timing compliance (2.5 V SSTL2), IEEE 802.3z-compliant GMII/RGMII/TBI support, and hardware-accelerated IPSec/SSL offload capability.

Technical Context

The MPC8347CVRAGDB implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports 32- or 64-bit interfaces at up to 333 MHz in TBGA packages, with full ECC, page mode (up to 16 open pages), and registered DIMM compatibility.

It integrates two TSEC Ethernet controllers compliant with IEEE 802.3, 802.3u, 802.3x, 802.3z, and 802.3ac standards, each with 2 KB TX/RX FIFOs, jumbo frame (9.6 KB) support, RMON statistics, and MII management. The security engine contains four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units for IPSec, SSL/TLS, and iSCSI processing.

FAQ

What is the maximum DDR SDRAM data rate supported by the MPC8347CVRAGDB?

The MPC8347CVRAGDB supports up to 333 MHz DDR-1 data rate in the TBGA-783 package, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6 of the MPC8347E Hardware Specifications (Rev. 11), which states "32- or 64-bit data interface, up to 333-MHz data rate for TBGA". The PBGA variant is limited to 266 MHz, but MPC8347CVRAGDB uses the TBGA package.

Does the MPC8347CVRAGDB include hardware acceleration for TLS/SSL processing?

Yes, the MPC8347CVRAGDB includes a dedicated security engine with AESU, DEU, MDEU (SHA-1/256, MD5), and RNG units that accelerate TLS/SSL record encryption, HMAC computation, and key exchange. As documented in Section 1.1, it handles "all the algorithms associated with IPSec, SSL/TLS, SRTP, IEEE Std. 802.11i®, iSCSI, and IKE processing" - enabling full SSL/TLS offload without CPU intervention.

What is the pin count and package type of the MPC8347CVRAGDB?

The MPC8347CVRAGDB uses a TBGA-783 package with 783 solder balls arranged in a 27 mm × 27 mm array and 1.0 mm ball pitch. This is explicitly stated in Section 18 ("Package and Pin Listings") and confirmed by the "RAGDB" suffix, where "R" denotes RoHS-compliant TBGA and "GDB" indicates the 783-ball configuration per Freescale's ordering nomenclature.

Can the MPC8347CVRAGDB operate in PCI host mode and PCI agent mode?

Yes, the MPC8347CVRAGDB supports both PCI host and PCI agent modes, as specified in Section 13. In host mode, it drives the PCI bus as a master; in agent mode, it responds to transactions initiated by an external host. The mode is selected via CFG_PCI_HOST bit, and the interface complies fully with PCI Specification Revision 2.2, including parity, coherency enforcement, and address translation.

What Ethernet standards does the MPC8347CVRAGDB's TSEC controllers comply with?

The dual TSEC controllers in the MPC8347CVRAGDB comply with IEEE 802.3®, 802.3u®, 802.3x®, 802.3z®, and 802.3ac® standards. They support 10/100 Mbps MII and 1000 Mbps GMII/RGMII/TBI/RTBI physical interfaces, with full-duplex operation, jumbo frames (9.6 KB), RMON statistics, and programmable CRC generation/checking - as detailed in Section 8 of the Hardware Specifications.
