GENERAL DESCRIPTION The PCF2116 family of LCD controller/drivers consists of 2 similar members: PCF2116X and PCF2114X, later ORDERING INFORMATION PACKAGE TYPE NUMBER PINS PCF2114XH PCF2116XH PCF2114XU PCF2116XU 128 128 116 116 PIN POSITION SQFP128 SQFP128 FFC116 FFC116
PCF2116 family (PCF2114X; PCF2116X)
referred to as PCF2116. The specific differences are expressed in separate paragraphs for PCF2116X and PCF2114X respectively. The letter X in PCF2116X or PCF2114X specifies the character set in the character generator ROM (CGROM). The different character sets currently available are specified by the letters A, C, G and J (see Figs 7 to 10). Set `A' in PCF2116A characterises the built-in standard character set. 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 characters. The PCF2116 interfaces to most microcontrollers via a 4 or 8-bit bus or via the 2-wire I2C-bus.
