NXP Semiconductors MPC8347ECVVAJDB

Overview

MPC8347ECVVAJDB from NXP (formerly Freescale) 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), DDR SDRAM 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 MPC8347ECVVAJDB datasheet, MPC8347ECVVAJDB pinout, MPC8347ECVVAJDB application, or MPC8347ECVVAJDB equivalent, key selection criteria include e300 core frequency headroom, dual TSEC timing compliance with IEEE 802.3z/802.3ac, DDR-1 ECC support, PCI 3.3-V agent/host mode flexibility, and crypto-channel concurrency for real-time IPsec offload.

Technical Context

The MPC8347ECVVAJDB implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports programmable timing, four banks (up to 1 Gbyte each), registered DIMM, and on-the-fly CKE-based self-refresh-enabling deterministic memory latency in real-time networking stacks.

Two independent TSEC modules provide full-duplex GMII/RGMII/TBI/RTBI and MII interfaces compliant with IEEE 802.3z and 802.3ac, each with 2-Kbyte TX/RX FIFOs, 9.6-Kbyte jumbo frame support, and RMON statistics. The integrated security engine includes four crypto-channels with dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), PKEU (RSA up to 2048-bit), and MDEU (SHA-1/SHA-256, MD5).

FAQ

What is the maximum DDR-1 data rate supported by the MPC8347ECVVAJDB?

The MPC8347ECVVAJDB supports DDR-1 SDRAM at up to 333 MHz in the TBGA package (672-pin), 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 MPC8347ECVVAJDB part number suffix 'JDB' denotes the TBGA package, validating the 333 MHz capability.

Does the MPC8347ECVVAJDB include hardware support for AES encryption?

Yes, the MPC8347ECVVAJDB includes a dedicated Advanced Encryption Standard Unit (AESU) within its security engine, supporting AES-128, AES-192, and AES-256 in ECB, CBC, CCM, and counter (CTR) modes. This is documented in Section 1.1 (Overview) of the MPC8347E Hardware Specifications (Rev. 11), where the AESU is listed as one of four crypto-execution units alongside DEU, PKEU, and MDEU.

Can the MPC8347ECVVAJDB operate as both a USB host and device simultaneously?

No, the MPC8347ECVVAJDB supports USB on-the-go (OTG) mode but cannot operate as host and device simultaneously on the same port. It features a dual-role controller that can be configured at boot time as either a USB host (with EHCI compatibility and 480 Mbps high-speed support) or a USB device (with six programmable endpoints). Section 1.1 confirms this functional duality but specifies mutually exclusive operational modes per port.

What is the thermal design power (TDP) of the MPC8347ECVVAJDB at 667 MHz?

At 667 MHz core frequency and 333 MHz DDR interface (TBGA package), the MPC8347ECVVAJDB has a maximum power dissipation of 3.6 W, as specified in Table 4 of the MPC8347E Hardware Specifications (Rev. 11). This value includes core power only and excludes I/O supply contributions (GVDD, LVDD, OVDD), which add approximately 0.76 W for DDR-1 at 333 MHz/64-bit per Table 5.

Is the MPC8347ECVVAJDB pin-compatible with other MPC8347E variants?

Yes, the MPC8347ECVVAJDB shares identical pinout and package (672-pin TBGA) with all MPC8347E variants ending in 'JDB', including MPC8347EVVAJDB and MPC8347ECVVAJDB. Section 18 ("Package and Pin Listings") of the Hardware Specifications confirms uniform pin mapping across JDB-suffixed parts, though electrical characteristics (e.g., voltage tolerances) may vary slightly between commercial and extended temperature grades.
