By Newhaven Display Intl 22
Newhaven Display International's line of multi-font displays feature an additional serial interface IC that has 50+ languages and 37 font tables. This multi-font IC contains ASCII, Unicode, and ISO8859 tables for flexibility and compatibility. The fonts featured are either fixed width or proportional width and can be read at a clock rate of up to 30 MHz.
When using this display line, the user’s MPU can communicate directly with this multi-font IC to read the font data strings and output the desired character onto the display. Using just a 4-wire SPI interface, the selected font data is read in vertical, structured bytes from the multi-font IC and is sent out to the display’s controller.
