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).

ORDERING INFORMATION

Note

1. The letter ‘x’ in the type number represents the letter of the required built-in character set: A, C or G.
