TECHNICAL DATA
DESCRIPTION
The LD1207 is specifically designed for LED and LED DISPLAY derivers.
The LD1207 have 12/9 segment output lines, 7 to 4 grid output lines, one display memory, control circuit and 3 line serial data interface.
This function are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer.
It is very convenience to control for numeric display.
LD1207’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages.
