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 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 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.

Features

• Single-chip LCD controller/driver
• 2-line display of up to 16 characters + 160 icons, or 1-line display of up to 32 characters + 160 icons
• 5 x 7 character format plus cursor; 5 x 8 for kana (Japanese) and user defined symbols
• Icon mode: reduced current consumption while displaying icons only
• Icon blink function
• On-chip:
  – Generation of LCD supply voltage, independent of V_DD, programmable by instruction (external supply also possible)
  – Temperature compensation of on-chip generated V_LCD: -8 to-12 mV/K at 5.0 V (programmable by instruction)
  – Generation of intermediate LCD bias voltages
  – Oscillator requires no external components (external clock also possible).
• Display Data RAM: 80 characters
• Character Generator ROM: 240, 5 x 8 characters
• Character Generator RAM: 16, 5 x 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, V_DD - V_SS = 2.2 to 4.0 V (up to 5.5 V if external V_LCD is used); chip may be driven with two battery cells
• Display supply voltage range, V_LCD - V_SS = 2.2 to 6.5 V
• Very low current consumption (20 to 200 µA):
  – Icon mode: <25 µA
  – Power-down mode: <2 µA.

Note
Icon mode is used to save current. When only icons are displayed, a much lower operating voltage V_LCD can be used and the switching frequency of the LCD outputs is reduced. In most applications it is possible to use V_DD as V_LCD.

Applications

• Telecom equipment
• Portable instruments
• Point-of-sale terminals.
