MicroZed is a low-cost development board from Avnet, the makers of the $475 ZedBoard and the entry level MiniZed development boards. Its unique design allows it to be used as both a stand-alone evaluation board for basic SoC experimentation or combined with a carrier card as an embeddable system-on-module (SOM).
The MicroZed processing system is based on the Xilinx Zynq®-7000 All Programmable SoC. The Zynq®-7000 All Programmable SoC (AP SoC) family integrates the software programmability of an ARM®-based processor with the hardware programmability of an FPGA, enabling key analytics and hardware acceleration while integrating CPU, DSP, ASSP, and mixed-signal functionality on a single device. The processing system offers the ability to run standard operating systems like Linux, real-time operating systems, or a combination of the two. The programmable logic provides a unique capability to create custom interfaces or custom accelerators. Together, they provide a versatile, performance optimized solution.
ZedBoard™ is a low-cost development board for the Xilinx Zynq®-7000 All Programmable SoC. This board contains everything necessary to create a Linux, Android, Windows® or other OS/RTOS-based design all at a cost of $495. The MicroZed sells for $199 with close performance and functionality with the ZedBoard. MicroZed contains two I/O headers that provide connection to two I/O banks on the programmable logic (PL) side of the Zynq – 7000 AP SoC device. In stand-alone mode, these 100 PL I/O are inactive. When plugged into a carrier card, the I/O are accessible in a manner defined by the carrier card design. The MicroZed board targets application in the areas of general FPGA evaluation and prototyping, embedded SOM applications, embedded vision, test & measurement, motor control, software-defined radio, industrial network and industrial IoT.
The Zedboard is based on Zynq-7020 with 85K logic cells while the MicroZed is based on the lower Zynq-7010 with a 28K logic cell. The MicroZed has 1GB RAM instead of 512 MB on the ZedBoard and has lesser interfaces as compared to the ZedBoard.
