What is a PowerQUICC II Pro? PowerQUICC II Pro is a family of communications processors from NXP (originally Freescale) designed for wired and wireless networking equipment, combining a Power Architecture CPU core with communications peripherals on a single die. The architecture hierarchy is: e300 core -> PowerQUICC II Pro -> MPC83xx series -> communications processor -> microprocessor -> semiconductor IC.
Key features include 400 MHz e300 core frequency, hardware MMU and double-precision FPU, dual 10/100/1000 Mbps Ethernet with GMII/RGMII/TBI support, dual PCI 2.3 controllers (one 64-bit/66 MHz, one 32-bit/66 MHz), Hi-Speed USB 2.0 host/device/OTG, DDR1/DDR2 SDRAM controller up to 333 MHz, four DMA channels, and an operating temperature range of -40C to +105C. The -FR suffix indicates a lead-free (Pb-free) TEPBGA II package per the Freescale/NXP package designation system.
The e300 core is a single-issue, seven-stage pipeline with hardware multiply/divide and 32 KB instruction + 32 KB data L1 caches. The integrated communications engine (QUICC Engine) offloads protocol processing for HDLC, ATM, Ethernet, and other telecom protocols. The 620-ball TEPBGA II package exposes the full peripheral set including two RGMII/GMII Ethernet interfaces, two PCI buses, dedicated DDR data/address/control balls, USB differential pairs, JTAG, and the QUICC Engine serial interfaces.
Typical applications include industrial routers, secure VPN gateways, enterprise class Ethernet switches, DSLAM line cards, wireless base station controllers, networked industrial automation, and Power-over-Ethernet (PoE) access points. The combination of dual GbE and dual PCI is particularly suited for SMB router/UTM platforms, where the CPU handles control-plane routing and the QUICC Engine handles wire-speed protocol encapsulation.
When designing with this device, allocate at least 6 PCB layers to maintain signal integrity on the DDR2 and RGMII interfaces. Provide bulk decoupling of 100 uF near the core supply and 10 uF/0.1 uF pairs adjacent to each supply ball. Ensure JTAG is accessible for production boundary-scan. The lead-free TEPBGA package has a peak reflow temperature of 260C per JEDEC J-STD-020.

설계 노트
Use a minimum 6-layer PCB stackup for the MPC8347CZQAGDB-FR. Route the DDR2 interface on inner layers with 50 ohm single-ended and 100 ohm differential impedance; length-match the DDR2 data byte lanes within +/- 25 mils and match the address/command traces within +/- 100 mils of the clock. Place the 1.2 V core bulk capacitors (100 uF polymer or ceramic) within 25 mm of the BGA, with 0.1 uF / 1 nF / 10 nF ceramic decouplers adjacent to each supply ball cluster. Provide a continuous ground plane on layer 2 directly beneath the BGA for thermal dissipation and signal return.
Estimated: At 400 MHz with both Ethernet ports active and DDR2 at 333 MHz, the MPC8347CZQAGDB-FR dissipates approximately 1.8 W to 2.5 W from the 1.2 V core rail. Using an estimated theta_JA of 18 C/W (620-TEPBGA II on a 6-layer board with bottom-side thermal pad), junction temperature rise above ambient is roughly 32C to 45C, keeping Tj well below the 105C limit at 70C ambient. For sealed enclosures with no airflow, add a copper heat spreader on the bottom side of the PCB or thermal vias under the BGA thermal balls. Always verify with a thermal probe of an actual production unit.
The RGMII and GMII Ethernet interfaces require source-series termination on the transmit clock and data lines to suppress reflections on the 1.2 ns rise-time edges. Place the GMII PHY within 50 mm of the BGA, with via count minimized on the clock pair. For the dual PCI 2.3 buses running at 66 MHz, route the 64-bit PCI on inner layers with controlled impedance and length-match the clock to within +/- 50 mils of the longest data line. Use IBIS-AMI simulation (available from NXP) to validate PCI signal integrity before committing to PCB layout.
Do not confuse the MPC8347 (dual GbE + dual PCI) with the MPC8343 (single GbE + single PCI) - although both share the 620-TEPBGA II footprint on some speed grades, the unused peripheral balls are not guaranteed to be No-Connect on all SKUs. Always cross-check the exact ball map for the substitute part before PCB reuse. Note that the -FR (lead-free), -VR (lead-free RoHS), and standard (leaded) suffixes differ in ball plating chemistry, which affects solder profile and rework. Finally, the JTAG TCK pin requires a 10 kohm pull-up to VCC; missing this causes boundary-scan failures in production.
Power sequencing for the MPC8347CZQAGDB-FR requires 1.2 V core to come up before or simultaneously with the 3.3 V I/O supply, but the core must stabilize within 100 ms of the I/O rail reaching its nominal value. Use a common power-good signal or a sequenced PGOOD chain from the PMIC. The 1.2 V core supply must deliver at least 3 A peak (inrush during DDR2 initialization) with less than 50 mVpp ripple. A buck regulator with at least 6 A rating and 1% output accuracy is recommended; NXP's MMPF0100 PMIC is a validated choice for the full MPC83xx family.
