GENERAL DESCRIPTION
1.1
Note
Icon mode is used to save current. When only icons are
displayed, a much lower operating voltage V
LCD
can be
used and the switching frequency of the LCD outputs is
reduced. In most applications it is possible to use V
DD
as
V
LCD
.

APPLICATIONS
•
Telecom equipment
•
Portable instruments
•
Point-of-sale terminals.
The PCF2113x is a low power CMOS LCD controller and
driver, designed to drive a dot matrix LCD display of 2-line
by 12 or 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. The letter ‘x’ in PCF2113x
characterizes the built-in character set. Various character
sets can be manufactured on request.
