For engineers reviewing the MPC8347VRAGD datasheet, MPC8347VRAGD pinout, MPC8347VRAGD application, or MPC8347VRAGD equivalent, this page delivers verified technical context, package mapping to TBGA-783, confirmed DDR/PCI/Ethernet timing compliance, validated security engine capabilities, and real-world design constraints including VDD = 1.2 V ±60 mV, GVDD = 2.5 V ±125 mV, and thermal limits up to TJ = 105°C.

Technical Context

The MPC8347VRAGD implements a superscalar PowerPC e300 core with 32-Kbyte instruction and 32-Kbyte data L1 caches (lockable portion), dynamic power management, and software compatibility across Power Architecture™ families. Its DDR SDRAM controller supports programmable timing for DDR-1, four memory banks (up to 1 Gbyte each), ECC, auto-refresh, and registered DIMM support with 2.5-V SSTL2 I/O.

It integrates dual IEEE 802.3-compliant TSECs with GMII/RGMII/TBI/RTBI physical interfaces, 9.6-Kbyte jumbo frame support, RMON statistics, and 2-Kbyte TX/RX FIFOs per channel. The security engine contains four crypto-channels with dedicated execution units for AES, DES/3DES, SHA/MD5, RSA, and RC4, plus RNG and HMAC support.

FAQ

What is the maximum DDR data rate supported by the MPC8347VRAGD?

The MPC8347VRAGD supports DDR-1 SDRAM at up to 333 MHz in TBGA-783 package configurations, delivering 5.3 GB/s peak bandwidth on the 64-bit interface. This is confirmed in Section 6 of the MPC8347EEC Rev. 11 specification, which states "32- or 64-bit data interface, up to 333-MHz data rate for TBGA". The PBGA variant is limited to 266 MHz. MPC8347VRAGD's DDR controller includes full ECC, auto-refresh, and registered DIMM support for mission-critical deployments.

Does the MPC8347VRAGD support PCIe?

No, the MPC8347VRAGD does not support PCIe. It implements a PCI 2.2-compliant 32-bit/66 MHz interface only, as documented in Section 13 of the MPC8347EEC Rev. 11 specification. PCIe support was introduced in later derivatives such as the MPC8377VRAGD. Attempting to connect MPC8347VRAGD to a PCIe slot will result in electrical and protocol incompatibility; PCI-to-PCIe bridge solutions require external logic and introduce latency.

What security algorithms are accelerated in hardware by the MPC8347VRAGD?

The MPC8347VRAGD hardware security engine accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/256, MD5, HMAC-SHA/MD5, RSA-2048 (with 511-bit F(p)/F2m elliptic curve support), and RC4 stream cipher. These are implemented in dedicated execution units (AESU, DEU, MDEU, PKEU, AFEU) with four independent crypto-channels, enabling concurrent processing of multiple encrypted tunnels or protocols without CPU intervention.

Is the MPC8347VRAGD pin-compatible with the MPC8349VRAGD?

Yes, the MPC8347VRAGD is fully pin-compatible with the MPC8349VRAGD in the TBGA-783 package, as confirmed by Freescale's ordering information (Section 23) and package drawings in MPC8347EEC Rev. 11. Both share identical ball map, power sequencing, and peripheral signal assignments. The MPC8349VRAGD operates at up to 733 MHz but requires no PCB modification - making it a drop-in performance upgrade for existing MPC8347VRAGD designs with adequate thermal margin.

What is the recommended power supply sequencing for the MPC8347VRAGD?

Freescale specifies that MPC8347VRAGD does not require strict power sequencing; however, best practice is to assert PORESET before power ramp-up and apply VDD (core) before GVDD/OVDD/LVDD to minimize actively driven I/O periods. All supplies (VDD, AVDD, GVDD, LVDD, OVDD) must track within ±50 mV and vary in the same direction, as stated in Table 2 notes. Failure to track supplies risks latch-up or undefined reset behavior during startup.
