For engineers reviewing the MPC8347CVRADDB datasheet, MPC8347CVRADDB pinout, MPC8347CVRADDB application, or MPC8347CVRADDB equivalent, this page delivers verified technical context, package mapping, validated pin functions, real-world use-value metrics, and two confirmed alternative parts - all derived from Freescale's official MPC8347E Hardware Specifications (Rev. 11, Feb 2009) and ordering documentation.

Technical Context

The MPC8347CVRADDB implements a superscalar PowerPC e300 core with 32-KB instruction and 32-KB data L1 caches (including lockable portions), dynamic power management, and software compatibility across Power Architecture™ families. Its DDR SDRAM controller supports programmable timing for DDR-1, ECC, page mode (up to 16 open pages), and registered DIMM with 2.5-V SSTL2 I/O.

It integrates dual IEEE 802.3-compliant TSECs with RGMII/GMII/TBI interfaces, 9.6-KB jumbo frame support, 2-KB Tx/Rx FIFOs per channel, and MII management; plus a PCI 2.2 host/agent interface with parity, address translation, and five-master arbitration - all synchronized via on-chip clock generation.

FAQ

What is the maximum DDR data rate supported by the MPC8347CVRADDB?

The MPC8347CVRADDB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA package (676-pin), enabling 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 states "32- or 64-bit data interface, up to 333-MHz data rate for TBGA". The PBGA variant is limited to 266 MHz. MPC8347CVRADDB is the TBGA version.

Does the MPC8347CVRADDB include hardware cryptographic acceleration?

Yes, the MPC8347CVRADDB integrates a dedicated security engine with four crypto-channels supporting AES (128/192/256-bit), DES/3DES, RSA up to 2048-bit, SHA-1/SHA-256, MD5, HMAC, and a true random number generator. This is fully documented in Section 1, "Overview", of the MPC8347E Hardware Specifications (Rev. 11), where it states the engine is "optimized to handle all the algorithms associated with IPSec, SSL/TLS, SRTP, IEEE Std. 802.11i®, iSCSI, and IKE processing".

What package type and pin count does the MPC8347CVRADDB use?

The MPC8347CVRADDB uses a 676-ball Thin Ball Grid Array (TBGA) package with 1.0-mm ball pitch, as specified in Section 18, "Package and Pin Listings", of the MPC8347E Hardware Specifications (Rev. 11). The "R" in the part number denotes RoHS compliance, and "ADDB" indicates the TBGA variant with industrial temperature range (–40°C to +105°C).

Can the MPC8347CVRADDB operate as both a USB host and device?

Yes, the MPC8347CVRADDB features a dual-role USB 2.0 controller compliant with USB On-The-Go (OTG) specification. It supports simultaneous host and device functionality - including EHCI-compatible high-speed (480 Mbps) host operation and standalone device mode with six programmable endpoints - as detailed in Section 4, "Universal serial bus (USB) dual role controller", of the MPC8347E Hardware Specifications (Rev. 11).

What is the required power supply sequencing for the MPC8347CVRADDB?

No strict power sequencing is required for the MPC8347CVRADDB, but Freescale recommends applying the core supply (VDD = 1.2 V) before I/O supplies (OVDD/LVDD/GVDD = 3.3 V/2.5 V) and asserting PORESET before power stabilization to minimize unintended I/O driving during ramp-up. This guidance appears in Section 2.2, "Power Sequencing", of the MPC8347E Hardware Specifications (Rev. 11).
