PCF21219DUGR/DAZ

PCF21219 LCD driver for character displays Rev. 1 — 14 January 2014 Product data sheet 1. General description The PCF21219 is a low power CMOS1 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 PCF21219 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 last letter in the type name, for example PCF21219DUGR, 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. For a selection of NXP LCD character drivers, see Table 50 on page 73. 2. Features and benefits  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  5  7 character format plus cursor; 5  8 for kana (Japanese) and user defined symbols  Reduced current consumption while displaying icons only  On-chip:  Configurable 4, 3, or 2 times voltage multiplier generating LCD supply voltage, independent of VDD, programmable by instruction (external supply also possible)  Temperature compensation of on-chip generated VLCDOUT: 0.16 %/K to 0.24 %/K (programmable by instruction)  Generation of intermediate LCD bias voltages  Oscillator requires no external components (external clock also possible)  Display Data RAM (DDRAM): 80 characters  Character Generator ROM (CGROM): 240 characters (5  8)  Character Generator RAM (CGRAM): 16 characters (5  8); 4 characters used to drive 160 icons  4-bit or 8-bit parallel bus and 2-wire I2C-bus interface  Pin compatible with PCF2119  Manufactured in silicon gate CMOS process  18 row and 80 column outputs 1. The definition of the abbreviations and acronyms used in this data sheet can be found in Section 21. PCF21219 NXP Semiconductors LCD driver for character displays  Multiplex rates 1:18 (2-line display or 1-line display), 1:9 (for 1-line display of up to 16 characters and 80 icons) and 1:2 (for icon only mode)  Uses common 11 code instruction set (extended)  Logic supply voltage: VDD1  VSS1 = 2.5 V to 5.5 V (chip may be driven with two battery cells)  LCD supply voltage: VLCDOUT  VSS2 = 2.5 V to 6.5 V  VLCD generator supply voltage: VDD2  VSS2 = 2.5 V to 4 V and VDD3  VSS2 = 2.5 V to 4 V  Direct mode to save current consumption for icon mode and multiplex drive mode 1:9 (depending on VDD2 value and LCD liquid properties)  Very low current consumption  Icon mode is used to save current. When only icons are displayed, a much lower LCD operating voltage can be used and the switching frequency of the LCD outputs is reduced; in most applications it is possible to use VDD as LCD supply voltage 3. Applications  Telecom equipment  Portable instruments  Point-of-sale terminals PCF21219 Product data sheet All information provided in this document is subject to legal disclaimers.
