• Manufacturer Part Number: lc75821e
• Description: Lcd Display Drivers
• Manufacturer: Sanyo Semiconductor Corporation

Data Transfer Format
1. Static (1/1) duty
2. 1/2 duty (Only 56 bits need to be transferred if there are no more than 52 display segments. The transfer format is
Data Transfer Examples
1. Static duty
2. 1/2 duty with 52 or fewer segments
3. 1/2 duty with more than 52 segments
identical to the static duty case. It is not possible to change the D54 to D106 data without specifying the D1 to D53
data.)
D1 to D53:
D1 to D106: Display data (1/2 duty) Unlighted at 0
DP:
Note: The following transfer format is not allowed in 1/2 duty with 52 or fewer segments.
