GENERAL DESCRIPTION
The PCF2104x 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.
The PCF2104x is optimized for chip-on-glass applications.
The ‘x’ in ‘PCF2104x’ represents a specific letter code for
a character set in the character generator ROM (CGROM).
Two standard character sets are currently available,
specified by the letters ‘C’ and ‘L’ (see Figs 5 and 6).
Other character sets are available on request.
The PCF2104x is a low-power CMOS LCD controller and
driver, designed to drive a split screen dot matrix LCD
display 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 VDD shutdown
the ESD protection system of the SCL and SDA pins does
not use a diode connected to VDD.
The chip contains a character generator and displays
alphanumeric and kana characters. The PCF2104x
interfaces to most microcontrollers via a 4 or 8-bit bus, or
via the 2-wire I2C-bus.
