PCF2119RU/2/F2Z

The PCF2119x is a low power CMOS LCD controller and driver, designed to drive a dot matrix LCD display of 2-lines by 16 characters or 1-line by 32 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 current consumption. The PCF2119x interfaces to most microcontrollers via a 4-bit or 8-bit bus or via the 2-wire I²C-bus. The chip contains a character generator and displays alphanumeric and kana (Japanese) characters. The letter ‘x’ in PCF2119x characterizes the built-in character set. Various character sets can be manufactured on request. In addition 16 user defined symbols (5 × 8 dot format) are available.

• Single-chip LCD controller and driver
• 2-line display of up to 16 characters plus 160 icons or 1-line display of up to 32 characters plus 160 icons
