FD2000
Rev1.0
1. OVERVIEW
The FD2000 is 1/8 to 1/10 duty dot matrix LCD display controller/drivers that supports the display of characters,
numbers, and symbols. In addition to generating dot matrix LCD drive signals based on data transferred serially
from a microcontroller, the FD2000 also provide on-chip character display ROM and RAM to allow display
systems to be implemented easily.
