16.2 General application information
16.3 4-bit operation, 1-line display using internal reset
16.4 8-bit operation, 1-line display using internal reset
The required minimum value for the external capacitors in an application with the
PCF2113x are: C
V
For COG applications the recommended Indium Tin Oxide (ITO) track resistance is to be
minimized for the I/O and supply connections. Optimized values for these tracks are below
50
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
have to be risen above the specified minimum.
The program must set functions prior to a 4-bit operation (see
turned on, 8-bit operation is automatically selected and the PCF2113x attempts to
perform the first write as an 8-bit operation. Since nothing is connected to DB0 to DB3, a
rewrite is then required. However, since one operation is completed in two accesses of
4-bit operation, a rewrite is required to set the functions (see
DB4 to DB7 of the ‘function set’ are written twice.

PCF2113x functions must be set by the ‘function set’ instruction prior to display. Since the
DDRAM can store data for 80 characters, the RAM can be used for advertising displays
