Avnet MiniZed單核Zynq 7Z007S入門開發(fā)方案

Avnet公司的MiniZed是Xilinx公司的單核Zynq 7Z007S器件的開發(fā)板,目標在具有低成本原型平臺的入門級Zynq開發(fā)設計師,可使設計者開發(fā)或評估Zynq處理器子系統(tǒng)(PS)和可編邏輯(PL)架構.開發(fā)板具有通過USB, Wi-Fi和藍牙進行板上連接,外設能插入兩個Pmod兼容的連接器, Arduino兼容的屏蔽接口或USB 2.0主接口, JTAG電路使用一根電纜通過 USB口連接筆記本電腦,就可以使開發(fā)板運行起來.主要應用在入門級/低成本Zynq開發(fā)環(huán)境,采Wi-Fi和藍牙的無線設計和演示,采用麥克風輸入的音頻信號處理,板上和外設傳感器的IoT/云連接.本文介紹了MiniZed開發(fā)板主要特性和所支持特性,框圖和拓撲圖,電路圖,材料清單和PCB設計圖.

MiniZed? is a single-core Zynq 7Z007S development board.With the advent of the latest cost-optimized portfolio fromXilinx, this board targets entry-level Zynq developers witha low-cost prototyping platform.

This compact design features on-board connectivity through USB, Wi-Fi andBluetooth. Peripherals can be plugged into dual Pmod-compatible connectors,the Arduino-compatible shield interface or the USB 2.0 host interface. JTAGcircuitry is incorporated onto the MiniZed base board, so with a single micro-USB cable to your laptop you are already up and running. User LED’s, a buttonand a switch allow for a physical board interface.

Micron memory solutions are presented for QSPI flash, DDR3L memory andon-board eMMC instead of an external SD card. The Murata Type 1DX wirelesssolution incorporates 802.11b/g/n Wi-Fi as well as Bluetooth 4.1, whichprovides both Bluetooth Classic and Low Energy (BLE). The integrated powersupply from Dialog generates all on-board voltages, while an auxiliary supplyinput can be used to power designs that require additional current. From STMicro there is an on-board motion and temperature sensor, as well as a digitalmicrophone.

MiniZed provides for an efficient hardware reference design, while it is alsoan inexpensive board that can be used to run workshops and tutorials. Theboard aims to showcase the power of Zynq, where the Cortex A9 processorcore integrates seamlessly with the programmable fabric to provide signalprocessing and control solutions. The on-board digital microphone serves asan input for a variety of illustrations of how to implement FIR filters, FFT’s anddirect memory access.
