ABOV MC2204
The MC2204 is specifically designed for LED and LED DISPLAY driver. The MC2204 has max 13 segment output lines, max 7 grid output lines, one display memory, control circuit, 4 line serial data interface, and max 10 x 2 matrix key scan . The more detail spec is listed below as Table 1.1.DESCRIPTION
Those functions are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. It is very convenient to control for numeric display. MC2204’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.FEATURES
