High anti-interference liquid crystal drive anti-static LCD driver chip VK2C21 anti-noise segment code driver IC [Copy link]

VK2C21 is a dot matrix storage mapped LCD driver that supports LCD screens with a maximum of 80 dots (20SEGx4COM) or a maximum of 128 dots (16SEGx8COM). The microcontroller can configure display parameters and read and write display data through the I2C interface, and can also enter power saving mode through instructions. Its high anti-interference and low power consumption characteristics are suitable for water, electricity, gas meters and industrial control instrument products. L63+05
