General Description
The VK2C23 device is a memory mapping and multi-function
LCD controller driver. The Display
segments of the device are 224 patterns (56 segments and 4commons) or 416 patterns (52 segments and
8commons). The software configuration feature of the VK2C23 device makes it suitable for multiple LCD
applications including LCD modules and display subsystems. The VK2C23 device communicates
with most microprocessors / microcontrollers via a two-line bidirectional I
2
C-bus.
