For engineers reviewing the MPC8347CZQAGDB datasheet, MPC8347CZQAGDB pinout, MPC8347CZQAGDB application, or MPC8347CZQAGDB equivalent, this page delivers verified silicon revision 1.1 specifications, confirmed TBGA-783 package mapping, validated DDR/PCI/TSEC timing compliance, and direct alternative part comparisons for migration planning in legacy Power Architecture-based networking platforms.

Technical Context

The MPC8347CZQAGDB implements a superscalar e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management - software-compatible with other Power Architecture processors. Its DDR SDRAM controller supports programmable timing for DDR-1, four memory banks (up to 1 Gbyte each), ECC, page mode (16 open pages), and registered DIMM compatibility with 2.5-V SSTL2 I/O.

Two TSEC modules provide IEEE 802.3/802.3u/802.3z-compliant 10/100/1000 Mbps operation via GMII/RGMII/TBI/RTBI/MII interfaces, each with 2 KB TX/RX FIFOs, 9.6 KB jumbo frame support, RMON statistics, and MII management. The PCI interface operates at 32-bit/66 MHz, supports host bridge and agent modes, parity, and hardware-enforced coherency.

FAQ

What is the maximum DDR data rate supported by the MPC8347CZQAGDB?

The MPC8347CZQAGDB supports DDR-1 SDRAM at up to 333 MHz (667 MT/s) in the TBGA-783 package, as specified in Table 4 of the MPC8347EEC Rev. 11 datasheet. This corresponds to a 32-bit or 64-bit interface with full ECC support, programmable timing, and registered DIMM compatibility - enabling up to 4 GB of error-corrected main memory in carrier-class router designs using MPC8347CZQAGDB.

Does the MPC8347CZQAGDB include hardware encryption acceleration?

Yes, the MPC8347CZQAGDB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256 (ECB/CBC/CCM/CTR), DES/3DES, SHA-1/256, MD5, HMAC, RSA-2048, and a true random number generator. This hardware offload enables line-rate IPSec and SSL/TLS processing without consuming e300 core cycles - a key capability confirmed in Section 1, "Overview", of the MPC8347EEC Rev. 11 specification for MPC8347CZQAGDB.

What package type and pin count does the MPC8347CZQAGDB use?

The MPC8347CZQAGDB uses a TBGA-783 package: 35 mm × 35 mm body size, 1.0 mm ball pitch, with thermal pad. Pinout is fully documented in Section 18, "Package and Pin Listings", of the MPC8347EEC Rev. 11 datasheet, including dedicated DDR, PCI, TSEC, USB, and JTAG signal groups - verified for MPC8347CZQAGDB revision 1.1 silicon.

Is the MPC8347CZQAGDB compatible with PCI Specification Revision 2.2?

Yes, the MPC8347CZQAGDB implements a full PCI 2.2-compliant interface operating at 32-bit/66 MHz, supporting both host bridge and agent modes, parity checking, delayed read transactions, write posting, and five-master arbitration - as detailed in Section 13, "PCI", of the MPC8347EEC Rev. 11 datasheet. This enables direct connection to standard PCI peripherals without external glue logic in MPC8347CZQAGDB-based systems.

What is the maximum operating frequency of the e300 core in the MPC8347CZQAGDB?

The e300 core in the MPC8347CZQAGDB operates at up to 667 MHz, as confirmed in the "Overview" section (page 2) of the MPC8347EEC Rev. 11 datasheet. This frequency is achievable with proper thermal management and 1.2 V ± 60 mV core supply, delivering approximately 1,400 DMIPS of Dhrystone 2.1 performance - a key specification validated for MPC8347CZQAGDB revision 1.1 silicon.
