Pin descriptions
Power supply (V
This pin is used to provide power to the Smart Reset™ device. A 0.1 µF ceramic decoupling
capacitor is recommended to be connected between the V
STM6524 device as possible.
Ground (V
Ground pin for the device.
Smart Reset™ input (SR0)
Push-button Smart Reset™ input is active-low with optional pull-up resistor. Both SR
inputs need to be asserted simultaneously for at least t

Reset output (RST)
RST is active-low or active-high, push-pull or open-drain reset output with optional internal
pull-up resistor. Output reset pulse width is optional as follows:
