NXP Semiconductors KMPC8347CVRAGDB

Overview

KMPC8347CVRAGDB from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating at up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSECs), DDR SDRAM memory controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2 interface, and hardware-accelerated security engine for IPSec/SSL/TLS. It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the KMPC8347CVRAGDB datasheet, KMPC8347CVRAGDB pinout, KMPC8347CVRAGDB application, or KMPC8347CVRAGDB equivalent, key selection criteria include e300 core frequency scaling, DDR-1 timing compliance (2.5-V SSTL2 I/O), TSEC RGMII/GMII interface support, PCI host/agent mode flexibility, and integrated crypto-channel concurrency for real-time packet encryption/decryption.

Technical Context

The KMPC8347CVRAGDB implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data caches, lockable L1 cache segments, and dynamic power management. Its DDR SDRAM controller supports four banks, ECC, page-mode operation, and auto-refresh with CKE-based sleep mode control.

Two independent TSEC modules each provide IEEE 802.3-compliant 10/100/1000 Mbps operation with RMON statistics, 9.6-Kbyte jumbo frame buffers, and MII management interfaces. The security engine integrates four crypto-channels with dedicated execution units for AES-128/192/256, DES/3DES, SHA-1/256, MD5, RSA up to 2048 bits, and RC4.

FAQ

What is the maximum DDR data rate supported by the KMPC8347CVRAGDB?

The KMPC8347CVRAGDB supports DDR-1 SDRAM at up to 333 MHz in the TBGA 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 specifies 333-MHz operation for TBGA variants and 266 MHz for PBGA. The controller implements programmable timing, full ECC, and registered DIMM support to ensure robust memory subsystem operation in industrial environments.

Does the KMPC8347CVRAGDB support PCIe or only legacy PCI?

The KMPC8347CVRAGDB implements PCI Specification Revision 2.2 - not PCIe - with a 32-bit, 66 MHz bus supporting both host bridge and agent modes. It lacks PCIe's point-to-point topology, serial differential signaling, and advanced power management features. Engineers must use discrete PCIe-to-PCI bridges if interfacing with PCIe peripherals. This limitation is explicitly documented in Section 13 of the MPC8347E Hardware Specifications, which details PCI 2.2 compliance including parity, prefetching, and delayed transaction support.

How many crypto channels does the KMPC8347CVRAGDB security engine provide?

The KMPC8347CVRAGDB security engine contains four independent crypto channels, each capable of executing concurrent command descriptor chains across AESU, DEU, PKEU, AFEU, and MDEU execution units. This architecture enables simultaneous processing of multiple IPSec or SSL sessions without CPU intervention. The four-channel structure is defined in Section 1 of the MPC8347E Hardware Specifications (Rev. 11), with each channel supporting 256-byte buffer sizes and flow control for large-data operations.

What Ethernet physical interfaces are supported by the KMPC8347CVRAGDB TSECs?

The KMPC8347CVRAGDB integrates two TSECs supporting IEEE 802.3-compliant 10/100/1000 Mbps operation via GMII, RGMII, TBI, RTBI, and MII interfaces. RGMII is commonly used for 1000 Mbps with reduced pin count, while MII handles 10/100 Mbps. Each TSEC includes 2-Kbyte TX/RX FIFOs, 9.6-Kbyte jumbo frame support, and RMON statistics. These capabilities are detailed in Section 8 of the MPC8347E Hardware Specifications, including electrical compliance with IEEE 802.3z and 802.3ab standards.

Is the KMPC8347CVRAGDB pin-compatible with the MPC8349E series?

Yes, the KMPC8347CVRAGDB is pin-compatible with the MPC8349EVRAGDB and other members of the MPC834xE family in the same TBGA package variant. Both share identical pin assignments for power, clocks, DDR, PCI, TSEC, and peripheral interfaces. Software compatibility is maintained through identical register maps and programming models, as confirmed in the MPC8349E Reference Manual and Section 23.1 of the MPC8347E Hardware Specifications, which lists KMPC8347CVRAGDB under "Part Numbers Fully Addressed by This Document" alongside MPC8349E derivatives.
