• Manufacturer Part Number: lc75833e
• Description: 1/3 Duty General-purpose Lcd Display Drivers
• Manufacturer: Sanyo Semiconductor Corporation

Serial Data Transfer Examples
• At the LC75833E and LC75833W when 73 or more segments are used, at the LC75833JE when 64 or more segments
Note: At the LC75833JE, the display data D34 to D36, D67 to D72, D103 to D105 must be set to 0.
• At the LC75833E and LC75833W when used with less than 73 segments, at the LC75833JE when used with less than
Note: At the LC75833JE, the display data D34 to D36 must be set to 0.
Control Data Functions
1. P0 to P3: Segment output port/general-purpose output port switching control data.
Note: Sn (n = 1 to 8): Segment output ports
are used.
144 bits of serial data must be sent.
64 segments.
Transfer either 48 bits or 96 bits of serial data depending on the number of segments used. However, the serial data
shown in the figure below (the display data D1 to D36 and the control data) must be sent.
These control data bits switch the S1/P1 to S8/P8 output pins between their segment output port and general-purpose
output port functions.
