16 APPLICATION INFORMATION
16.1
The required minimum value for the external capacitors in
an application with the PCF2119x are as follows: C
V
V
recommended for ripple rejection.
For COG applications the recommended ITO track
resistance is to be minimized for the I/O and supply
connections. Optimized values for these are below 50
for the supply and below 100

Higher track resistance reduces performance and
increases current consumption.
To avoid accidental triggering of power-on reset
(especially in COG applications), the supplies must be
adequately decoupled. Depending on power supply
