` Display Data RAM: 80 characters
` Character Generator ROM: 240, 5 ´ 8 characters
` Character Generator RAM: 16, 5 ´ 8 characters;
  4 characters used to drive 160 icons, 8 characters used
  if icon blink feature is used in application
` 4 or 8-bit parallel bus and 2-wire I2C-bus interface
` CMOS compatible
` 18 row and 80 column outputs
` Multiplex rates 1 : 18 (for normal operation), 1 : 9 (for
  single line operation) and 1 : 2 (for icon only mode)
` Uses common 11 code instruction set (extended)
` Logic supply voltage range, VDD1 - VSS = 1.5 to 5.5 V
  (chip may be driven with two battery cells)
` Display supply voltage range, VLCD - VSS = 2.2 to 6.5 V
` HVgen supply voltage range, VDD2 - VSS = 2.2 to 4 V
  and VDD3 - VSS = 2.2 to 4 V
` Direct mode to save current consumption for icon mode
  and Mux 1 : 9 (depending on VDD2 value and LCD liquid properties)
` Very low current consumption (20 to 200 mA):
Icon mode: <25 mA
Power-down mode: <2 mA.

Description

The PCF2119x is a low power CMOS LCD controller and driver, designed to drive a dot matrix LCD display of 2-line by 16 or 1-line by 32 characters with 5 ´ 8 dot format. All necessary functions of PCF2119X 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 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.
