LCD driver output (1/3 duty, 1/2 bias, R/C type)
LCD driver output
The output number of the HT49R50 LCD driver
can be 33 2 or 33 3 or 32 4 by options (i.e., 1/2
duty or 1/3 duty or 1/4 duty). The bias type of
LCD driver can be "R" type or "C" type. If the "R"
bias type is selected, no external capacitor is re-
quired. If the "C" bias type is selected, a capacitor
mounted between C1 and C2 pins is needed. The
bias voltage of LCD driver can be 1/2 bias or 1/3
bias by options. If 1/2 bias is selected, a capacitor
mounted between V2 pin and ground is required.
If 1/3 bias is selected, two capacitors are needed
forV1andV2pins.Refertoapplicationdiagram.
Buzzer
HT49R50 provides a pair of buzzer output BZ
and BZ, which share pins with PA0 and PA1 re-
spectively, ad determined by options. Its output
frequency can be selected by options.
When the buzzer function is selected, setting
the PA.0 and PA.1 "0" simultaneously, will en-
ables the buzzer output and sets the PA.0 "1" to
disable the buzzer output.
