General Description
The HT16E07 is an electronic paper display (EPD)
driver IC. It consists of 120 segments and 4 background
or common selectable outputs. The output drivers
have a three level driving voltage to match the EPD
characteristic. The driving voltage is generated by a
charge pump circuit.
The HT16E07 device communicates with external
microcontrollers using its internal 3-wire SPI serial
interface.
