AiP1637 – 2-Wire Serial Interface, Common Anode, 6-Digit 8-Segment LED Driver with 8×2 Key Scan

The AiP1637 is a high-integration LED driver IC designed to control 6-digit 8-segment common anode displays with an integrated 8×2 key scan matrix, making it ideal for applications requiring both visual display and input functionality. With a simple 2-wire serial interface (CLK, DIO), it allows seamless communication with microcontrollers while minimizing pin usage. Internally, it features display RAM, a display blanking function to avoid ghosting, a software-adjustable brightness controller, and an RC oscillator, significantly reducing the need for external components. Packaged in DIP20 or SOP20, the AiP1637 is widely used in home appliances, consumer electronics, and industrial control systems where compact and efficient LED display control is essential.
