MOS INTEGRATED CIRCUIT
µPD16315
1/4- to 1/12-DUTY FIP^TM(VFD) CONTROLLER/DRIVER
DESCRIPTION
The µPD16315 is a FIP (Fluorescent Indicator Panel, or Vacuum Fluorescent Display) controller/driver that is driven on a
1/4- to 1/12- duty factor. It consists of 16 segment output lines, 4 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 µPD16315 through a three-line serial
interface. This FIP controller/driver is ideal as a peripheral device for a single-chip microcomputer.
FEATURES
• Multiple display modes: 16-segment & 12-digit to 24-segment & 4-digit
• Key scanning: 16 x 2 matrix
• Dimming circuit: 8 steps
• High-withstanding-voltage output: VDD − 35 V MAX.
• LED ports: 4 chs., 20 mA MAX.
• No external resistors necessary for driver outputs: P-ch open-drain + pull-down resistor output
• Serial interface: CLK, STB, DIN, DOUT
