"TM1637" is used to identify a 7-segment Display and Keyboard scanning IC
"TM1637" is also used to identify display/keypad modules using this part
Features: 20-pin surface mount part 6 character - 7-segment display 8 brightness levels 16 button keypad (2x8 matrix) Built-in oscillator 2-wire I2C like control signals, CLK, DIO When purchasing a four character display, it will either support a ':' to be used as a clock OR, each character will have decimal point support. This is a function of the module, not the IC.
Notes:
Although the 2-wire interface appears to be "I2C like", it is NOT I2C. The module does not have or supports an I2C address.
