LCD Display Drivers
Overview
The LC75821E and LC75821W are general-purpose LCD
display drivers that can be used for frequency display in
microprocessor-controlled radio receivers and in other
display applications.
Features
• 53 segment outputs (the maximum for static drive)
• Two drive types: static (1/1) duty (53 segments) and 1/2
duty (104 segments)
• Data input: 3 serial input pins
• INH pin for turning off all display output
• The difference form the LC7582: The LC75821E,
LC75821W are A/D converter, DSP function-removed
versions of the LC7582 of which the functions other
than the two can be used with pin compatibility with
the LC7582 kept.

Function
Segment output pins
Common output pins (Only COM1 is used in static (1/1) drive. COM2 must be left open in that mode.)
LCD bias voltage setting
Oscillator connection
Serial data transfer inputs
Power supply
Display off control input
INH = low (VSS) ..........Display off (S1 to S53, COM1, COM2 = low)
INH = high (VDD).........Display on
Note that serial data transfers can be performed when display output is forced off.
Make no connections to this pin.

Display Examples
1. Static drive (1/1 duty)
Example with 40 segments (Up to 53 segments can be driven.)
2. 1/2 duty drive
Note: Numbers in circles indicate the number of segments used.
Example with 80 segments (Up to 104 segments can be driven.)
