It can be used for frequency display in microprocessor-controlled receiver and in other display application. The FD1000A chooses numbers of common and general-purpose output ports by instructions. Therefor, It drives 156-segment at 1/3 duty in use of 3 commons or 204-segment at 1/4 duty in use of 4 commons. Also it provides 12 general-purpose output ports. Features Programmable Duty Ratio 1/3 Duty : Up to 156 Segment Outputs 1/4 Duty : Up to 204 Segment Outputs Programmable LCD Bias Ratio : 1/2 Bias or 1/3 Bias Programmable General-purpose Output Port Function (Only 1/4 Duty Mode) Internal LCD Driving Voltage Generator Circuit Normal & Diminish LCD Dividing resistors Selection (Only 1/4 Duty Mode) Power Saving Mode and all Segment OFF Function RC Oscillation Circuit Serial Interface ( SI, SCK, CE and INH/ ) for 3V or 5V Power supply Voltage : 2.7V ~ 5.5V Package Type 64-LQFP-1414, 64-LQFP-1010 2 / 20 FD1000A Pin Assignment 3/4COM LCD Driver Block Diagram 3 / 20 FD1000A Pin Descriptions Pin No. 1 ~ 12 3/4COM LCD Driver Pin Name SEG1/ P1 ~ SEG12/ P12 I/O O Pin Description LCD Segment output pins / General-purpose output pins(Only 1/4Duty Mode) Select Segment output pins or General-purpose output pins by the instruction. 13 ~ 51 52 SEG13~SEG51 SEG52/ COM0 O O LCD Segment output pins.

Duty Selection : Duty select address is which sets LCD driving duty ratio 1/3 or 1/4 duty. Address = 41 Hex, 1/3 Duty ( 3-Common 52-Segment LCD Driver ) Address = 80 Hex, 1/4 Duty ( 4-Common 51-Segment LCD Driver ) DR : 1/2 or 1/3 Bias Selection Bit DR data = “0” , 1/2 Bias Drive = “1” , 1/3 Bias Drive SC : Segment ON/OFF Control Bit SC data = “0” , Display ON = “1” , Display OFF BU : Power saving Control Bit BU data = “0” , Normal Mode = “1” , Power-saving Mode. In this mode the Oscillator is stopped and the segment pins output Vss levels. CU : LCD dividing resistors selection bit (Only 1/4 Duty Mode) CU data = “0” , Normal Mode (RLCD=R) = “1” , Low current Mode (RLCD=2*R) 5 / 20 FD1000A 3/4COM LCD Driver PC0 to PC1 : Segment /General-purpose output pin selection bits (Only 1/4 Duty Mode) Note : SEGn(n=1~12) : Segment output pin function, Pn (n=1~12) : General-purpose output pin function When selected, following data are assigned. For example, When the general-purpose output pin function is selected for SEGn/Pn output pins, that output pin will output a high level data Dn is “1”, and will output a low level when Dn is “0”. 6 / 20 FD1000A 1/3 Duty 3/4COM LCD Driver Display Data to Segment Output Pin Correspondence (1) Note : When Display Data is “1”, the Segment ON.

While the INH\ pin is held low, the micro-controller should send the serial data and set INH\ pin high after the transfer completes.
