General application information
The required minimum value for the external capacitors in
an application with the PCF2113x are: C
Ext
for
V
LCD
/V
SS
= 100 nF min., for V
DD
/V
SS
= 470 nF. Higher
capacitor values are recommended for ripple reduction.
For COG applications the recommended ITO track
resistance is to be minimized for the I/O and supply
connections.
Optimized values for these tracks are below 50
for the
supply and below 100
for the I/O connections. Higher
track resistance reduce performance and increase current
consumption.
To avoid accidental triggering of Power-on reset
(especially in COG applications), the supplies must be
adequately decoupled. Depending on power supply
quality, V
DD1
may have to be risen above the specified
minimum.
