NXP Semiconductors MPC8347EVVAJDB

Overview

MPC8347EVVAJDB from NXP (formerly Freescale) is a PowerQUICC II Pro integrated host processor built on Power Architecture® e300 core, operating up to 667 MHz with 32-Kbyte instruction and 32-Kbyte data L1 cache. It integrates dual 10/100/1000-Mbps Ethernet controllers (TSEC), DDR1/DDR2 SDRAM controller (up to 400 MHz in TBGA), PCI 2.3 interface, USB 2.0 dual-role controller, security engine with AES/DES/RSA acceleration, and I²C/DMA/DUART peripherals - deployed in network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the MPC8347EVVAJDB datasheet, MPC8347EVVAJDB pinout, MPC8347EVVAJDB application, or MPC8347EVVAJDB equivalent, key selection criteria include e300 core frequency headroom, TSEC RGMII/GMII timing compliance, DDR2 1.8-V I/O voltage tolerance, PCI 3.3-V agent/host mode flexibility, and hardware-accelerated IPSec/SSL offload capability for real-time encrypted traffic handling.

Technical Context

The MPC8347EVVAJDB implements a superscalar e300 core with floating-point, integer, load/store, and branch units, coupled with dynamic power management and software compatibility across Power Architecture families. Its memory subsystem supports DDR1 (2.5-V SSTL2) and DDR2 (1.8-V SSTL2) with ECC, up to 4 banks × 1 Gbyte, and programmable timing for 266–400 MHz data rates depending on package.

Networking is handled by two IEEE 802.3-compliant TSECs with MII/RGMII/GMII/TBI interfaces, 9.6-Kbyte jumbo frame support, RMON statistics, and 2-Kbyte TX/RX FIFOs per channel. The security engine features four crypto-channels with dedicated AESU (128/192/256-bit keys), DEU (DES/3DES), PKEU (RSA up to 2048-bit), and MDEU (SHA-1/224/256, MD5).

FAQ

What is the maximum DDR2 data rate supported by the MPC8347EVVAJDB?

The MPC8347EVVAJDB supports DDR2 SDRAM at up to 400 MHz data rate in the TBGA package variant, corresponding to 800 MT/s. This is achieved with 1.8-V SSTL2 I/O, programmable timing, and hardware ECC - verified in revision 3.x silicon and later. The PBGA variant is limited to 266 MHz (533 MT/s). Actual achievable rate depends on board layout, DRAM part selection, and thermal conditions.

Does the MPC8347EVVAJDB support PCIe or only PCI?

The MPC8347EVVAJDB implements PCI Specification Revision 2.3 (32-bit, 66 MHz), not PCIe. It supports both PCI host bridge and agent modes, with features including parity, prefetching, and five-master arbitration. PCIe is absent - designs requiring PCIe must use later families like MPC85xx. The MPC8347EVVAJDB's PCI interface remains fully compatible with legacy add-in cards and bridge chips.

How many crypto algorithms does the MPC8347EVVAJDB security engine accelerate?

The MPC8347EVVAJDB security engine accelerates AES (128/192/256-bit keys in ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), RSA/DH up to 2048-bit, ECC (F2m/Fp up to 511-bit), SHA-1/224/256, MD5, HMAC, RC4, and random number generation. All are executed in dedicated hardware units across four independent crypto-channels - enabling concurrent IPSec, SSL, and iSCSI session offload without CPU intervention.

Is the MPC8347EVVAJDB pin-compatible with the MPC8347EA?

Yes, MPC8347EVVAJDB is a qualified, enhanced-speed grade of the MPC8347EA with identical 672-pin TBGA footprint, pin assignment, and electrical signaling. The 'V' suffix denotes extended temperature range (–40°C to +105°C), and 'JDB' indicates lead-free, RoHS-compliant packaging. Firmware and hardware designs for MPC8347EA are directly reusable with MPC8347EVVAJDB.

What USB modes does the MPC8347EVVAJDB support, and what PHY interface is required?

The MPC8347EVVAJDB supports USB 2.0 On-The-Go (dual-role) operation - functioning as either host or device. It requires an external PHY connected via ULPI (UTMI+ Low Pin Interface), which uses only 12 signals (vs. 32+ for full UTMI), reducing PCB complexity. The controller implements EHCI for high-speed host mode and standard device-mode endpoints - no internal PHY is integrated.
