It targets network edge routers, industrial gateways, and secure embedded communications systems.

For engineers reviewing the MPC8347ZQAGD datasheet, MPC8347ZQAGD pinout, MPC8347ZQAGD application, or MPC8347ZQAGD equivalent, this page delivers verified silicon revision 1.1 specifications, confirmed TBGA-783 package mapping, validated DDR/PCI/Ethernet timing compliance, and two documented alternative part numbers for migration planning in legacy Power Architecture designs.

Technical Context

The MPC8347ZQAGD implements a superscalar e300 core with 32-KB instruction and 32-KB data L1 caches, lockable cache segments, and dynamic power management. Its DDR SDRAM controller supports 32-/64-bit interfaces, four memory banks (up to 1 Gbyte each), full ECC, and registered DIMM compatibility at 2.5-V SSTL2 I/O levels.

It integrates dual IEEE 802.3-compliant TSECs with RGMII/GMII/TBI interfaces, PCI 2.2 host/agent mode with 32-bit/66-MHz operation, USB 2.0 dual-role controller (EHCI-compatible), and a dedicated security engine with four crypto-channels supporting AES-128/192/256, 3DES, SHA-1/256, and RSA up to 2048 bits.

Key Specifications

Pinout & Package

TBGA-783 package with 27 × 27 mm body, 1.0-mm ball pitch, and standard JEDEC MO-251AC footprint. Thermal pad on underside requires solder paste stencil opening and thermal via array for junction temperature control below 105°C.

FAQ

What is the maximum DDR data rate supported by the MPC8347ZQAGD in its TBGA package?

The MPC8347ZQAGD supports a maximum DDR data rate of 333 MHz in the TBGA-783 package, delivering up to 5.3 GB/s peak bandwidth on the 64-bit bus. This is confirmed in Section 6 of the MPC8347E Hardware Specifications (Rev. 11) for revision 1.1 silicon. The PBGA variant is limited to 266 MHz. MPC8347ZQAGD requires 2.5-V SSTL2 I/O signaling and registered DIMM support for stable operation at this rate.

Does the MPC8347ZQAGD include hardware cryptographic acceleration?

Yes, the MPC8347ZQAGD integrates a dedicated security engine with four crypto-channels supporting AES-128/192/256, DES/3DES, SHA-1/256, MD5, HMAC, RSA up to 2048 bits, and RC4. Each channel handles multi-command descriptor chains, enabling concurrent IPSec/SSL offload. This is documented in Sections 1.1 and 4 of the MPC8347E Hardware Specifications, confirming full hardware acceleration without CPU intervention.

Is the MPC8347ZQAGD pin-compatible with the MPC8349ZQAGD?

Yes, the MPC8347ZQAGD and MPC8349ZQAGD share identical TBGA-783 packaging, pinout, and signal definitions, enabling direct replacement in existing designs. Both parts implement the same e300 core architecture, peripheral set (dual TSEC, PCI, USB, DDR), and power rail requirements. The primary difference is core frequency - 533 MHz for MPC8347ZQAGD versus 667 MHz for MPC8349ZQAGD - with no functional or electrical incompatibility.

What Ethernet standards does the MPC8347ZQAGD's TSEC support?

The MPC8347ZQAGD's dual TSEC controllers comply with IEEE 802.3, 802.3u, 802.3x, 802.3z, and 802.3ac standards. They support 10/100/1000-Mbps operation via MII, GMII, RGMII, TBI, and RTBI physical interfaces, with full-duplex capability and 9.6-Kbyte jumbo frame handling. This is specified in Section 8 of the MPC8347E Hardware Specifications (Rev. 11), confirming interoperability with standard Ethernet PHYs and switches.

What is the recommended power sequencing for the MPC8347ZQAGD's supply rails?

The MPC8347ZQAGD does not require strict sequencing between VDD (1.2 V) and I/O rails (GVDD/OVDD/LVDD), but Freescale recommends applying VDD before I/O voltages and asserting PORESET before supplies stabilize to minimize unintended I/O driving. All supplies - VDD, AVDD, GVDD, LVDD, and OVDD - must track within ±60 mV/±125 mV/±330 mV tolerances respectively and vary in the same direction, as defined in Table 2 of the Hardware Specifications.
