Anachip AD6311
The AD6311 is a VFD (Vacuum Fluorescent Display) controller/driver that is driven on a 1/8- to 1/16 duty factor (include key scan). It consists of 12 segment/key scan output lines, 8 grid output lines, 8 segment/grid output drive lines, a display memory, a control circuit, and a key scan circuit. Serial data is input to the AD6311 through a four-line serial interface.FEATURES
- 4-pin serial interface - Key scanning (12x4 matrices) - Programming display modes (16-digit & 12- segment to 8-digit & 20-segment) - Programming dimming step - High-voltage output (VDD-35V max) - 5 channels LED ports - 4-pin general-purpose input port - Built-in oscillator - No external resistor necessary for driver outputs Pin AssignmentsGENERAL DESCRIPTION
