Icon mode is used to save current. When only icons
are displayed, a much lower operating voltage V

can be used and the switching frequency of the LCD
outputs is reduced. In most applications it is possible
to use V

GENERAL DESCRIPTION
The PCF2113x is a low power CMOS LCD controller and
driver, designed to drive a dot matrix LCD display of 2 line
by 12 and 1 line by 24 characters with 5
×
8 dot format.
All necessary functions for the display are provided in a
single chip, including on-chip generation of LCD bias
voltages, resulting in a minimum of external components
and lower system current consumption. The PCF2113x
interfaces to most microcontrollers via a 4 or 8-bit bus or
via the 2-wire I
2
C-bus. The chip contains a character
generator and displays alphanumeric and kana
(Japanese) characters. Three character sets (A, D and E)
are currently available (see Figs 7, 8 and 9). Various other
character sets can be manufactured on request.
