Reset

A push-button reset switch with a Schmitt-triggered device (DS1818) is provided for the IGLOO nano
AGLN250 FPGA populated on the board. This Schmitt trigger device can be bypassed because an
AGLN250 FPGA supports additional I/O advanced features such as Schmitt trigger.

The DS1818 uses a precision temperature-compensated reference and comparator circuit to monitor the
status of the power supply (VCC). When an out-of-tolerance condition is detected, an internal power-fail
signal is generated which forces reset to the active state. When VCC returns to an in-tolerance condition,
the reset signal is kept in the active state for approximately 150 ms to allow the power supply and
processor to stabilize.

Reference

Additional information on this push-button reset switch is available at the IGLOO nano Starter Kit
website:

RESET Switch

Notes:
When Schmitt-triggered chip is used, keep the capacitor
NL (Default). When IGLOO's Schmitt trigger I/O is used,
keep DS1818 NL and populate the capacitor to implement
standard RC Reset Push-Button Switch.
