TM1652 SOP16 UART Interface Segment LED Display Driver Chip

TM1652 is a dedicated LED (light-emitting diode, digital tube, dot matrix screen) drive control chip, which integrates digital communication circuits, decoding circuits, data latches, oscillators, and LED drive circuits. The communication method adopts the asynchronous serial port communication (UART) protocol because the chip only receives the data sent by the single-chip microcomputer, and only one TX port of the single-chip microcomputer is required to send data to the chip to realize single-line communication: in terms of the display driver, the chip adopts a dynamic scanning method, Two display modes are optional, 8-level segment drive current is adjustable, and 16-level bit duty cycle is adjustable: TM1652 has a built-in blanking processing optimization circuit.
