TM1637 LED Display Driver IC – 6-Digit 7-Segment Controller – SOP-20 – Titan Micro

The TM1637 from Titan Micro Electronics is a compact and efficient LED display driver and key-scan controller IC, widely used in digital clocks, counters, appliances, dashboards, and display/keypad modules. Provided in a SOP-20 (300 mil) surface-mount package, it integrates display control and keypad scanning into a single device, reducing MCU pin usage and simplifying system design.

The TM1637 supports 6-digit, 7-segment common-anode LED displays (8 segments × 6 bits) and features an 8×2 key scan interface, enabling up to 16 keys to be read directly without additional components. With only two microcontroller pins (CLK and DIO) required for communication, it offers a streamlined solution for display control systems.

Operating from 4.5V to 5.5V, the IC includes 8-level adjustable brightness, a built-in RC oscillator, and power-on reset, ensuring stable operation in a wide range of embedded applications.
