NXP Semiconductors MPC8347CVVAGDB

Overview

MPC8347CVVAGDB from Freescale Semiconductor is a PowerQUICC™ II Pro integrated host processor featuring an embedded PowerPC e300 core operating up to 667 MHz, dual 10/100/1000 Mbps Ethernet controllers (TSEC), DDR SDRAM controller supporting 32-/64-bit interfaces at up to 333 MHz (TBGA), PCI 2.2-compliant 32-bit/66 MHz interface, and hardware security engine with AES-128/192/256, DES/3DES, SHA-1/256, and RSA acceleration - deployed in carrier-grade edge routers and industrial gateways requiring deterministic real-time packet processing.

For engineers reviewing the MPC8347CVVAGDB datasheet, MPC8347CVVAGDB pinout, MPC8347CVVAGDB application, or MPC8347CVVAGDB equivalent, this page delivers verified electrical specs (1.2 V core, 2.5 V DDR I/O, 3.3 V I/O), thermal power data (2.4 W max @ 533 MHz TBGA), PCIe-adjacent timing constraints, DDR-1 SDRAM controller register mapping, and validated alternative processors for migration paths in networking infrastructure designs.

Technical Context

The MPC8347CVVAGDB implements a superscalar PowerPC e300 core with 32 KB instruction and 32 KB data L1 caches, lockable cache segments, and dynamic power management - software-compatible with Power Architecture™ families. Its DDR SDRAM controller supports four banks, ECC, page mode (up to 16 open pages), and registered DIMM with 2.5-V SSTL2 I/O.

Dual TSECs comply with IEEE 802.3z/802.3ab/802.3ac, offering GMII/RGMII/TBI/RTBI physical layer support, 9.6-Kbyte jumbo frames, RMON statistics, and 2-Kbyte TX/RX FIFOs per channel. The security engine integrates four crypto-channels with dedicated AESU, DEU, PKEU, MDEU, and RNG units for IPSec/SSL/TLS offload.

FAQ

What is the maximum DDR-1 data rate supported by the MPC8347CVVAGDB?

The MPC8347CVVAGDB supports DDR-1 SDRAM at up to 333 MHz data rate in the TBGA package variant, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This specification applies only to revision 1.1 silicon and earlier; later revisions (A/B suffix) require consulting the MPC8347EA Hardware Specifications document for updated timing parameters and DDR-2 compatibility notes.

Does the MPC8347CVVAGDB include hardware cryptographic acceleration?

Yes, the MPC8347CVVAGDB integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, SHA-1/256, MD5, HMAC, RSA-2048, and true random number generation. This enables full IPSec and SSL/TLS offload without consuming e300 core cycles - critical for maintaining throughput in encrypted VPN gateway applications using the MPC8347CVVAGDB.

What package type and pin count does the MPC8347CVVAGDB use?

The MPC8347CVVAGDB uses a 689-ball Thin Ball Grid Array (TBGA) package measuring 27 mm × 27 mm with 1.0 mm ball pitch. It is RoHS-compliant and features an exposed thermal pad on the underside for heatsink attachment - consistent with Freescale's AN3531 thermal design guidelines for sustained 3.6 W operation at 105°C junction temperature.

Can the MPC8347CVVAGDB operate in both PCI host and agent modes?

Yes, the MPC8347CVVAGDB supports configurable PCI operation in both host bridge and agent modes. In host mode, it drives the PCI bus using CLKIN as the primary clock source; in agent mode, it synchronizes to PCI_SYNC_IN. The mode is selected via configuration pins at reset, and the interface complies fully with PCI Specification Revision 2.2 including parity, address translation, and five-master arbitration - essential for flexible system architecture using the MPC8347CVVAGDB.

What is the recommended core supply voltage tolerance for the MPC8347CVVAGDB?

The MPC8347CVVAGDB requires a core supply voltage (VDD) of 1.2 V ±60 mV, as specified in Table 2 of the Hardware Specifications document. This tight tolerance must be maintained across all 16 VDD pins simultaneously, and VDD must track AVDD, GVDD, LVDD, and OVDD during power-up sequences to prevent latch-up or initialization failure - a critical constraint in power delivery design for any system deploying the MPC8347CVVAGDB.
