For engineers reviewing the MPC8347CZUAJDB datasheet, MPC8347CZUAJDB pinout, MPC8347CZUAJDB application, or MPC8347CZUAJDB equivalent, this page delivers verified silicon revision 1.1 specifications, TBGA-783 package mapping, DDR/PCI/TSEC timing constraints, e300 core cache configuration, and validated alternative parts for migration paths in legacy PowerQUICC II Pro designs.

Technical Context

The MPC8347CZUAJDB implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches (lockable portions), dynamic power management, and software compatibility across Power Architecture™ families. Its DDR SDRAM controller supports programmable timing for DDR-1, four banks up to 1 Gbyte each, ECC, page mode (16 open pages), and registered DIMM support with 2.5-V SSTL2 I/O.

It integrates dual TSECs compliant with IEEE 802.3/802.3u/802.3z/802.3ac, supporting GMII/RGMII/TBI/RTBI physical interfaces, 9.6-Kbyte jumbo frames, RMON statistics, and 2-Kbyte TX/RX FIFOs per channel. The PCI interface operates as both host bridge and agent, supports parity, selectable coherency, and address translation units between host and peripheral address spaces.

FAQ

What is the maximum DDR data rate supported by the MPC8347CZUAJDB?

The MPC8347CZUAJDB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA-783 package, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This specification is validated for revision 1.1 silicon and requires 2.5-V SSTL2-compatible I/O voltage (GVDD) with full ECC and registered DIMM support. The actual achievable rate depends on PCB layout quality, termination, and DRAM chip selection per Freescale AN3698.

Does the MPC8347CZUAJDB include hardware cryptographic acceleration?

Yes, the MPC8347CZUAJDB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, SHA-1/256, MD5, HMAC, RSA up to 2048-bit, and elliptic curve cryptography. It achieves 100+ Mbps IPSec throughput with <5% CPU utilization, enabling real-time SSL/TLS offload in Linux or VxWorks environments without external co-processors.

What package type and pin count does the MPC8347CZUAJDB use?

The MPC8347CZUAJDB uses a TBGA-783 package: 27 mm × 27 mm body size, 1.0 mm ball pitch, and JEDEC MO-251AC footprint. It features 783 I/O balls including power, ground, DDR, TSEC, PCI, and peripheral interfaces. Thermal pad on the underside requires specific solder paste volume per Freescale AN3702 to ensure reliable heat dissipation in 24/7 operation.

Can the MPC8347CZUAJDB operate in both PCI host and agent modes?

Yes, the MPC8347CZUAJDB supports configurable PCI operation: as a host bridge managing downstream devices or as a PCI agent responding to transactions from an external host. The mode is selected via CFG_PCI_MODE strap pins at reset. In host mode, CLKIN serves as the primary clock; in agent mode, PCI_SYNC_IN becomes the timing reference - both requiring ±150 ps jitter compliance.

What is the function of the lockable portion of the L1 cache in the MPC8347CZUAJDB?

The lockable portion of the 32-Kbyte instruction and 32-Kbyte data L1 caches in the MPC8347CZUAJDB ensures deterministic real-time execution by preventing critical firmware routines or interrupt service code from being evicted during cache misses. This guarantees sub-10 μs worst-case interrupt latency in VxWorks or RTEMS deployments, essential for industrial motion control and telecom timing applications.
