The HT16K33A is a memory mapping and multi-function LED controller driver. The maximum display segment numbers in the device is 128 patterns (16 segments and 8 commons) with a 13×3 (MAX.) matrix key scan circuit. The software configuration features of the HT16K33A makes it suitable for multiple LED applications including LED modules and display subsystems. The HT16K33A is compatible with most microcontrollers and communicates via a two-line bidirectional I2C bus.
