Figure 1: Hardware Block Diagram
The main component of the Mercury SA1 SoC module is the Intel Cyclone V SoC device. Most of its I/O
pins are connected to the Mercury module connectors, making 150 regular user I/Os available to the user.
Further, six multi-gigabit transceivers with support for PCIe Gen1 4 are available on the module connectors.
The SoC device can boot from the on-board QSPI flash or from an external SD card. For development pur-
poses, a JTAG interface is connected to Mercury module connector.
The memory subsystem is built from a 64 MB QSPI flash and 1 GB DDR3L SDRAM in the standard config-
uration. Starting with revision 3 modules, a 16 GB eMMC flash is available on the module for booting the
SoC device or for storing user data.
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 50 MHz crystal oscillator.
