MPC82xx系列应用开发系统

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. PQ2FADS-VR板支持MPC8250、MPC8270和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). 板载接口包括JTAG/COP、双UART、USB 1.1、两个100/10-Base-T高速以太网接口和一个支持光纤的155 Mbps ATM UNI接口。

使用ADS板载资源和相关的调试器，开发人员可以下载和运行代码，设置断点，显示存储器与寄存器，以及通过扩展连接器连接专有硬件。That code can then be incorporated into the desired system with the MPC82xx processor. PQ2FADS-VR提供板载资源和调试器，让开发人员下载和运行代码，设置断点，以及显示存储寄存器和配置寄存器。

哪些人应该订购本产品：

使用采用516引脚PBGA (ZQ或VR)封装的任何PQ2衍生产品的开发人员。For PCI applications, NXP® also offers the MPC8266ADS-PCIAI as a PCI target board.
