3 GENERAL DESCRIPTION
The PCF2116 family of LCD controller/drivers consists of
the PCF2116x, the PCF2114x and the PCF2116K.
The term ‘PCF2116’ is used to refer to all devices for
common information. Specific information is given in
separate paragraphs.
The ‘x’ in ‘PCF2116x’ and ‘PCF2114x’ represents a
specific letter code for a character set in the character
generator ROM (CGROM). The different character sets
currently available are specified by the letters A, C, and G
(see Figs 8 to 10). Other character sets are available on
request.
The PCF2116 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 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 power consumption. The chip contains a character
generator and displays alphanumeric and kana
(Japanese) characters. The PCF2116 interfaces to most
microcontrollers via a 4 or 8-bit bus or via the 2-wire
I2C-bus. To allow partial VDD shutdown the ESD protection
system of the SCL and SDA pins does not use a diode
connected to VDD.
The PCF2116K differs from the other members of the
family in that:
• VLCD/VOP generation is different (see Section 8.1)
• It is available with character set C only (see Fig.9).
