EV6411-S-00A Evaluation Kit Windowed Watchdog Timer Evaluation Board
The EV6411-S-00A is an evaluation board for
MP\MPQ6411, a windowed watchdog timer. It used to reset and monitor the microcontroller. In normal operation, MCU sends trigger signal to MPQ6411 in a defined time window cyclically. A missing or fault trigger signal causes the watchdog to reset the MCU.
MPQ6411 provides a reset signal (low level voltage) to MCU during power-up or under voltage.
By setting the MODE pin to high or low, the watchdog can work as long window mode or short window mode. And the window is programmable.
The EV6411-S-00A is assembled and tested with SOIC8 package.
