Multi-Font Displays Slide 5

The multi-font displays have a built-in serial interface memory IC with preloaded font tables. These font tables contain the dot-matrix (pixel) data that makes up each individual character in the supported languages. The multi-font IC communicates with the main host MPU by receiving the specified font address and then sending the dot-matrix data back to the main host MPU. When the data is received by the main host MPU, it can then be written to the display data RAM.
