General Description
The HT16L23 device is a memory mapping and
multi-function LCD controller/driver. The display
segments of the device are 208 patterns (52 segments
and 4 commons) for 1/4 duty display or 384 patterns
(48 segments and 8 commons) for 1/8 duty display.
It can also support LED drive outputs on certain
segment pins. The software configuration feature of
the HT16L23 device makes it suitable for multiple
LCD applications including LCD modules and display
subsystems. The HT16L23 device communicates with
most microprocessors/microcontrollers via a two-wire
bidirectional I2C or a three-wire SPI interface.
