3 / 72 page  2001 Dec 19 3 Philips Semiconductors Product specification LCD controllers/drivers PCF2113x 1 FEATURES • Single-chip LCD controller/driver • 2-line display of up to 12 characters + 120 icons, or 1-line display of up to 24 characters + 120 icons • 5 × 7 character format plus cursor; 5 × 8 for kana (Japanese) and user defined symbols • Icon mode: reduced current consumption while displaying • Icon blink function • On-chip: – Configurable 4, 3 or 2 voltage multiplier generating LCD supply voltage, independent of VDD, programmable by instruction (external supply also possible) – Temperature compensation of on-chip generated VLCD: −0.16 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: 80 characters • Character generator ROM: 240, 5 × 8 characters • Character generator RAM: 16, 5 × 8 characters; 3 characters used to drive 120 icons, 6 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 60 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 − VSS1 = 1.8 to 5.5 V (chip may be driven with two battery cells) • VLCD generator supply voltage range VDD2 − VSS2 = 2.2 to 4.0 V • Display supply voltage range VLCD − VSS2 = 2.2 to 6.5 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 µA): – Icon mode: <25 µA – Power-down mode: <2 µA. 1.1 Note Icon mode is used to save current. When only icons are displayed, a much lower operating voltage VLCD can be used and the switching frequency of the LCD outputs is reduced. In most applications it is possible to use VDD as VLCD. 2 APPLICATIONS • Telecom equipment • Portable instruments • Point-of-sale terminals. 3 GENERAL DESCRIPTION The PCF2113x is a low power CMOS LCD controller and driver, designed to drive a dot matrix LCD display of 2-line by 12 or 1-line by 24 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 PCF2113x 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 PCF2113x characterizes the built-in character set. Various character sets can be manufactured on request. |
