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. 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 x 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:
