NXP Semiconductors MPC8347EVVAJD

Overview

MPC8347EVVAJD from NXP Semiconductors (formerly Freescale) is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 533 MHz, dual 10/100/1000-Mbps Ethernet controllers (TSECs), DDR SDRAM controller supporting 333-MHz data rate in TBGA package, PCI 2.2 interface, and hardware security engine with AES-256, DES/3DES, SHA-256, and RSA acceleration - deployed in network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the MPC8347EVVAJD datasheet, MPC8347EVVAJD pinout, MPC8347EVVAJD application, or MPC8347EVVAJD equivalent, key selection considerations include its 533-MHz e300 core frequency, TBGA-783 package with 2.5-V DDR I/O and 3.3-V PCI/local bus compatibility, dual TSEC support for IEEE 802.3z/802.3ab, and integrated security engine with four crypto-channels - all critical for deterministic real-time networking and encrypted data path design.

Technical Context

The MPC8347EVVAJD 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-/64-bit interfaces, four memory banks (up to 1 GB each), ECC, and registered DIMM compatibility at 333 MHz in TBGA configuration.

It integrates two IEEE 802.3-compliant TSECs with RGMII/RTBI/GMII/TBI physical layer support, 9.6-KB jumbo frame handling, and 2-KB TX/RX FIFOs per channel. The on-die security engine includes dedicated execution units for AES-256 (ECB/CBC/CTR/CCM), DES/3DES, SHA-256/MD5, RSA up to 2048 bits, and a true random number generator - all accessible via four independent crypto-channels.

FAQ

What is the maximum DDR data rate supported by the MPC8347EVVAJD?

The MPC8347EVVAJD 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 specifies 333 MHz operation for TBGA variants - distinct from the 266 MHz limit for PBGA packages. The MPC8347EVVAJD achieves this with programmable timing, full ECC, and registered DIMM support.

Does the MPC8347EVVAJD include hardware acceleration for TLS/SSL protocols?

Yes, the MPC8347EVVAJD includes a dedicated security engine with AESU (supporting AES-128/192/256 in CBC/CTR/CCM modes), MDEU (SHA-1/SHA-256, MD5), and PKEU (RSA up to 2048 bits), enabling full TLS 1.2 handshake and record-layer acceleration. These units are accessible via four independent crypto-channels and are explicitly cited in the Overview section of the MPC8347E Hardware Specifications as optimized for SSL/TLS and IPSec processing.

What package type and pin count does the MPC8347EVVAJD use?

The MPC8347EVVAJD uses a TBGA-783 package: 27 mm × 27 mm body, 1.0-mm ball pitch, lead-free and RoHS-compliant. This is confirmed in Section 18 ("Package and Pin Listings") and Table 23-1 ("Ordering Information") of the MPC8347E Hardware Specifications (Rev. 11), where "VVAJD" suffix denotes the TBGA-783 variant with industrial temperature range (–40°C to +105°C).

Can the MPC8347EVVAJD operate in both PCI host and agent modes?

Yes, the MPC8347EVVAJD supports configurable PCI operation in both host and agent modes, as documented in Section 13 ("PCI") of the Hardware Specifications. In host mode, CLKIN serves as the primary clock source; in agent mode, PCI_SYNC_IN is used. The device implements PCI Specification Rev. 2.2 features including 32-bit/66-MHz operation, parity, address translation, and on-chip arbitration for five masters - all verified for MPC8347EVVAJD in revision 1.1 silicon.

What is the function of the QUIESCE pin on the MPC8347EVVAJD?

The QUIESCE pin on the MPC8347EVVAJD is an active-high input that places the processor into a low-power quiescent state, halting the core clock while maintaining DDR self-refresh and peripheral register state. As specified in Table 8 ("RESET Pins DC Electrical Characteristics"), QUIESCE shares electrical characteristics with PORESET/HRESET/SRESET and is asserted synchronously with the system clock to ensure deterministic entry into power-managed mode - critical for energy-constrained edge nodes.
