Pinout
1. VCC (Pin 8): This pin is connected to the supply voltage that needs to be monitored.
2. GND (Pin 4): Ground reference for the device.
3. RESET (Pin 1): Active-low reset output. It provides a reset signal to the microprocessor when VCC falls below the threshold.
4. RESET (Pin 2): Active-high reset output, used similarly to the RESET pin but with an active-high signal.
5. MR (Pin 3): Manual reset input. When pulled low, it forces a reset.
6. PBRST (Pin 5): Push-button reset input. Allows for manual reset via an external push button.
7. TD (Pin 6): Timeout delay. It sets the delay time for the reset signal.
8. NC (Pin 7): No connection or sometimes used for additional functions depending on the specific package version.
These pins help the UM805RE ensure reliable operation by initiating resets during power-up, power-down, and brownout conditions.
