Improve the anti-jamming performance of sensitive devices is considered from the side of sensitive devices to minimize interference with the pick-up noise, and from the abnormal state as soon as possible to restore the method. The following electrostatic discharge generator manufacturers on the Hailing world to improve the anti-jamming performance of sensitive devices commonly used measures:
1, the wiring loop to minimize the area of the loop to reduce the induced noise.
2, wiring, power lines and ground to try to rough. In addition to reducing the voltage drop, it is more important to reduce the coupling noise.
3, for the MCU idle I / O port, do not vacant, to ground or power. The idle terminals of other ICs are grounded or connected to the power supply without changing the system logic.
4, the use of single-chip power monitoring and watchdog circuits, such as: IMP809, IMP706, IMP813, X25043, X25045, etc., can greatly improve the anti-jamming performance of the entire circuit.
5, the speed can meet the requirements of the premise, try to reduce the single-chip crystal oscillator and the use of low-speed digital circuits.
6, IC devices as far as possible directly welded on the circuit board, less IC Block.
