General Description

The HT16K33 is a memory mapping and multi-function LED controller driver. The max. 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 HT16K33 makes it suitable

for multiple LED applications including LED modules and display subsystems. The HT16K33 is

compatible with most microcontrollers and communicates via a two-line bidirectional I2C-bus.
