2 Module Description
2.1 Block Diagram
Figure 1: Hardware Block Diagram
The main component of the Mars ZX3 SoC module is the Xilinx Zynq-7000 SoC device. Most of its I/O pins
are connected to the Mars module connector, making 108 user I/Os available to the user.
The SoC device can boot from the on-board QSPI flash, NAND flash or from an external SD card. For de-
velopment purposes, a JTAG interface is connected to Mars module connector.
The available standard configurations include 512 MB NAND flash, a 64 MB quad SPI flash and 512 MB or 1
GB DDR3 SDRAM.
Further, the module is equipped with a Gigabit Ethernet PHY and a USB 2.0 OTG PHY, making it ideal for
communication applications.
A real-time clock is available on the module and is connected to the global I2C bus.
On-board clock generation is based on a 33.33 MHz crystal oscillator.
The module can be operated using a single input supply of 3.3 V DC. All other necessary supply voltages are
generated on-board. Some of these voltages are available on the Mars module connector to supply circuits
on the base board.
Four LEDs are connected to the SoC pins for status signaling.
