Functional Description

Power

System Controller provides control and status information for main power rails. By default all power rails are ON, the user can manipulate power using I²C interface, see  Memory map table.

Reset

System controller generates a reset pulse to supervisor chip U69 when front panel button S3 is pressed.

JTAG

JTAG interface from FTDI controller passes through System Controller to FPGA.

I²C Interface

To use SC I²C interface corresponding connection should be configured in the FPGA project. There are 2 standard I²C interface controllers, which can be used AXI_IIC or Zynq UltraScale+ MPSoC integrated I²C controller.

...

Zynq UltraScale+ MPSoC integrated I²C controller

Project XDC file should contain

Code Block
set_property PACKAGE_PIN G18 [get_ports {MAX_IO1}]
set_property PACKAGE_PIN G19 [get_ports {MAX_IO2}]
set_property PACKAGE_PIN K18 [get_ports {MAX_IO3}]
set_property PACKAGE_PIN H19 [get_ports {MAX_IO4}]
set_property IOSTANDARD LVCMOS33 [get_ports MAX_IO*]
set_property PULLUP true [get_ports {MAX_IO2}]
set_property PULLUP true [get_ports {MAX_IO4}]


With this configuration, I²C device with address 0x20 should be visible on I²C bus

...

This device is an emulation of TCA6416 I²C GPIO Chip. GPIO input and output pins are used to get status and control the system.
