NXP Semiconductors MPC8347CZUAGDB

Overview

MPC8347CZUAGDB from NXP (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 (TSEC), DDR SDRAM controller supporting 333-MHz data rate in TBGA package, PCI 2.2 interface, and hardware security engine with AES, DES, SHA, and RSA acceleration. It targets network edge routers, industrial gateways, and secure communications appliances.

For engineers reviewing the MPC8347CZUAGDB datasheet, MPC8347CZUAGDB pinout, MPC8347CZUAGDB application, or MPC8347CZUAGDB 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 MPC8347CZUAGDB 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 banks up to 1 Gbyte each, full ECC, and registered DIMM compatibility with 2.5-V SSTL2 I/O.

It integrates two IEEE 802.3-compliant three-speed Ethernet controllers (TSECs) with RGMII/GMII/TBI interfaces, 9.6-Kbyte jumbo frame support, and 2-Kbyte TX/RX FIFOs per channel. The on-die security engine includes dedicated execution units for AES (128/192/256-bit keys), DES/3DES, SHA-1/SHA-256, MD5, and RSA up to 2048 bits across four programmable crypto-channels.

FAQ

What is the maximum DDR data rate supported by the MPC8347CZUAGDB?

The MPC8347CZUAGDB supports a maximum DDR-1 data rate of 333 MHz in the TBGA package, corresponding to 667 MT/s. This is achieved with a 64-bit interface and requires GVDD = 2.5 V ± 125 mV. The controller supports full ECC, registered DIMMs, and programmable timing for DRAM chips ranging from 64 Mbit to 1 Gbit. Performance is validated per Freescale MPC8347E Hardware Specifications Rev. 11, Table 4 and Section 6.

Does the MPC8347CZUAGDB include hardware cryptographic acceleration?

Yes, the MPC8347CZUAGDB integrates a dedicated security engine with four crypto-channels and five execution units: AESU (128/192/256-bit keys), DEU (DES/3DES), MDEU (SHA-1/SHA-256, MD5), PKEU (RSA up to 2048 bits), and RNG. It accelerates IPSec, SSL/TLS, and IEEE 802.11i protocols. The engine supports concurrent command descriptor chains and is documented in Sections 1.1 and 4 of the MPC8347E Hardware Specifications Rev. 11.

What package type and pin count does the MPC8347CZUAGDB use?

The MPC8347CZUAGDB uses a TBGA-783 package: 27 mm × 27 mm body size, 1.0-mm ball pitch, arranged in a 27 × 27 grid. This is confirmed in Section 18 ("Package and Pin Listings") of the MPC8347E Hardware Specifications Rev. 11. The "ZUA" suffix in the part number explicitly denotes the TBGA package variant, distinct from PBGA options.

Can the MPC8347CZUAGDB operate as both a PCI host and PCI agent?

Yes, the MPC8347CZUAGDB supports both PCI host bridge and PCI agent modes, configurable via boot-time settings. In host mode, it drives the PCI bus and manages transactions; in agent mode, it responds to accesses from an external host. The interface complies with PCI Specification Revision 2.2, supports 32-bit/66-MHz operation, parity, and address translation - details are in Section 13 of the MPC8347E Hardware Specifications Rev. 11.

What is the core voltage requirement for the MPC8347CZUAGDB?

The MPC8347CZUAGDB requires a core supply voltage (VDD) of 1.2 V ± 60 mV, as specified in Table 2 of the MPC8347E Hardware Specifications Rev. 11. This supply must track AVDD (PLL supply) and all I/O supplies (GVDD, LVDD, OVDD) during power-up and operation. Failure to maintain this tolerance risks timing violations or functional failure, particularly at 533-MHz operation.
