| Description | The TM1638 is an integrated LED display driver and key scanning controller IC designed for multi-digit 7-segment display applications. It operates with a supply voltage of 3.3 V to 5.5 V and uses a 3-wire serial interface (STB, CLK, DIO), enabling simple communication with microcontrollers. The device supports up to 8 digits with 8 segments each and includes an integrated key scan function for up to 24 keys. It features 8-step brightness control via PWM, an internal oscillator, and automatic display refresh for stable and flicker-free operation.
Mechanically, the TM1638 is available in SOP-28 and DIP-28 packages, suitable for both SMD and through-hole designs. It integrates segment and grid drivers internally, reducing external component count and PCB complexity. The device is widely used in control panels, consumer electronics, audio equipment, and embedded systems requiring combined display and keypad functionality. |
