Avnet MiniZed单核Zynq 7Z007S入门开发方案

Avnet公司的MiniZed是Xilinx公司的单核Zynq 7Z007S器件的开发板,目标在具有低成本原型平台的入门级Zynq开发设计师,可使设计者开发或评估Zynq处理器子系统(PS)和可编逻辑(PL)架构.开发板具有通过USB, Wi-Fi和蓝牙进行板上连接,外设能插入两个Pmod兼容的连接器, Arduino兼容的屏蔽接口或USB 2.0主接口, JTAG电路使用一根电缆通过 USB口连接笔记本电脑,就可以使开发板运行起来.主要应用在入门级/低成本Zynq开发环境,采Wi-Fi和蓝牙的无线设计和演示,采用麦克风输入的音频信号处理,板上和外设传感器的IoT/云连接.本文介绍了MiniZed开发板主要特性和所支持特性,框图和拓扑图,电路图,材料清单和PCB设计图.

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.
