摘要
A printing consumables chip comprises a base plate which is provided with a first electrical contact, a second electrical contact, and an electronic module which connects with two electrical contacts. The electronic module comprises a microcontroller, and a clock circuit which provides a clock signal to the microcontroller. The modulation circuit comprises a switch device. A control terminal of the switch device is connected with a first pin of the microcontroller and two output terminals of the switch device are connected with the first electrical contact and the ground, respectively. The clock circuit comprises a comparison unit. A first input terminal of the comparison unit is connected with an external clock signal and a second input terminal. The first pin receives the control signal from the output terminal of the comparison unit, and the control terminal of the switch device is connected with a second pin of the microcontroller.
