GENERAL DESCRIPTION
The PCF2105 integrated circuit is similar to the PCF2114x
(described in the “PCF2116 family”data sheet) but does
not contain the high voltage generator of that device.
Furthermore, a fast I
2
C-bus interface (400 kHz) is
provided.
The PCF2105 is optimized for chip-on-glass applications.
A specific letter code ‘M’ for a character set is programmed
in the Character Generator ROM (CGROM) (see Fig.5).
The PCF2105 is a low power CMOS LCD controller/driver,
designed to drive a split screen dot matrix LCD of
1 or 2 lines by 24 characters or 2 or 4 lines by
12 characters with a 5
×
8 dot format. All necessary
functions for the display are provided in a single chip,
including on-chip generation of LCD bias voltages which
results in a minimum of external components and lower
system power consumption. To allow partial V
DD
shutdown
the ESD protection system of the SCL and SDA pads does
not use a diode connected to V
DD
.
The chip contains a character generator and displays
alphanumeric and kana characters. The PCF2105
interfaces to most microcontrollers via a 4 or 8-bit parallel
bus, or via the 2-wire I
2
C-bus.
