For engineers reviewing the MPC8347CVVAJFB datasheet, MPC8347CVVAJFB pinout, MPC8347CVVAJFB application, or MPC8347CVVAJFB equivalent, this page delivers verified silicon revision (1.1), confirmed TBGA-783 package mapping, validated DDR/PCI/Ethernet timing constraints, exact e300 core cache configuration (32 KB I-Cache + 32 KB D-Cache), and real-world power dissipation data (2.4 W typical at 533 MHz/133 MHz CSB) - all extracted from Freescale's official MPC8347EEC Rev. 11 hardware specifications.

Technical Context

The MPC8347CVVAJFB implements a superscalar PowerPC e300 core with floating-point, integer, load/store, and branch execution units, lockable L1 cache, and dynamic power management. It integrates dedicated hardware accelerators including four crypto-channels with PKEU (RSA up to 2048-bit), AESU (ECB/CBC/CTR/CCM), DEU (DES/3DES), MDEU (SHA-1/256, MD5), and RNG.

Its memory subsystem includes a DDR SDRAM controller with ECC support, page-mode operation (up to 16 open pages), and registered DIMM compatibility; dual TSECs compliant with IEEE 802.3z/802.3ac for GMII/RGMII/TBI/RTBI; and a PCI 2.2 host/agent interface with parity, prefetching, and coherency enforcement - all synchronized via on-chip clock generation.

FAQ

What is the silicon revision level supported by MPC8347CVVAJFB?

MPC8347CVVAJFB corresponds to revision 1.1 silicon, as documented in Freescale's MPC8347EEC Rev. 11 specification. This revision does not include enhancements introduced in revision 3.0 silicon (covered under MPC8347EA part numbers), such as updated DDR2 timing and revised PLL behavior. Designers must use the MPC8347EEC Rev. 11 document for accurate electrical and timing validation of MPC8347CVVAJFB.

Does MPC8347CVVAJFB support DDR2 memory?

No, MPC8347CVVAJFB supports DDR1 SDRAM only, with programmable timing for DDR-1 devices operating at up to 333 MHz in TBGA packages. DDR2 support was introduced in later variants like MPC8349E. The MPC8347CVVAJFB DDR controller lacks DDR2-specific features such as ODT control, DLL-off mode, and 2.5 V SSTL_2 I/O drive strength tuning - all required for DDR2 compliance.

What are the key power supply sequencing requirements for MPC8347CVVAJFB?

MPC8347CVVAJFB requires all supply rails - VDD (1.2 V), AVDD (1.2 V), GVDD (2.5 V), LVDD (2.5/3.3 V), and OVDD (3.3 V) - to track within ±60 mV (VDD/AVDD) or ±125–330 mV (I/O rails) and vary in the same direction during ramp-up/ramp-down. Core voltage should be applied before I/O voltages, and PORESET must be asserted before supplies stabilize to prevent unintended I/O driving during power transition.

Can MPC8347CVVAJFB operate in PCI host mode with 66 MHz bus speed?

Yes, MPC8347CVVAJFB supports PCI host mode at 66 MHz with full PCI Specification Revision 2.2 compliance, including parity, delayed read transactions, and memory prefetching. Its PCI interface operates at 3.3 V and supports both host bridge and agent functionality - enabling direct connection to peripheral cards or use as a PCI master in backplane-based systems.

How many independent crypto channels does the security engine in MPC8347CVVAJFB provide?

The security engine in MPC8347CVVAJFB provides four independent crypto channels, each capable of executing multi-command descriptor chains. These channels dynamically allocate execution units (AESU, DEU, MDEU, PKEU, AFEU) under controller arbitration - enabling concurrent AES encryption, SHA-256 hashing, and RSA signature verification without CPU intervention.
