MPC82xx Family Application Development System

PQ2FADS_VR

The PQ2FADS-VR boards are designed to aid hardware and software developers of the PowerQUICC® II family by providing an evaluation platform for MPC82xx derivatives in the 516-pin PBGA (VR or ZQ) packages. The PQ2FADS-VR board supports the MPC8250, MPC8270 and MPC8275.

The PQ2FADS-VR board has 32MB of SDRAM attached to the 60x bus (soldered on board), 8MB of SDRAM for the local bus (soldered on board) and an 8MB Program Flash SIMM (supports up to 32MB). The on-board interfaces include JTAG/COP, Dual UART, USB 1.1, two 100/10-Base-T Fast Ethernets, and a 155 Mbps ATM UNI with optical interface.

Using the ADS on-board resources and an associated debugger, developers are able to download and run code, set breakpoints, display memory and registers, and connect proprietary hardware via the expansion connectors. That code can then be incorporated into the desired system with the MPC82xx processor. The PQ2FADS-VR includes on-board resources and a debugger that allows developers to download and run code, set breakpoints, display memory registers, and display configuration registers.

Who should order this product:

Developers using any PQ2 derivative in the 516-pin PBGA (VR or ZQ) packages. For PCI applications, NXP® also offers the MPC8266ADS-PCIAI as a PCI target board.

Connectivity

  • On-board COP/JTAG connector
  • On-board logic to support direct connection to standard Parallel Port (EPP/SPP modes) in desktop PC for debugging purposes using Code Warrior tools
  • PCI Local Bus is PCI Standard 2.2 compliant
  • 3 PCI slots are available to host up to three leaders/targets cards at 3.3 V only--arbitration is supported by the on-chip arbiter
  • PCI bus supports 25-66 MHz at 3.3 V devices (determined by the user)
  • Simple generic Interrupt Controller to handle the PCI interrupts (four in each PCI slot)
  • Module Enable Indications for all on-board modules
  • High density (MICTOR) Logic Analyzer connectors, carrying all 60x, local bus and CPM signals, for fast logic analyzer connection
  • 155 Mbps ATM UNI on FCC1 with Optical I/F, connected to the PQ2 via UTOPIA Level 2 I/F supporting 8/16 bit in single/multi PHY, using the PMC-SIERA 5384
  • Two 100/10-Base-T Ports on FCC2 and FCC3 with T.P. I/F, MII/RMII controlled, using Davicom DM9161
