General description

The PCF2113x is a low-power CMOS LCD controller and driver, designed to drive a dot matrix LCD display of 2 lines of 12 characters or 1 line of 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-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.

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 for e.g. additional segment display section: reduced current consumption while displaying icons only

■ Icon blink function

■ Very low current consumption (20 μA to 200 μA):

◆ Icon mode: < 25 μA

◆ Power-down mode: < 2 μA

■ On-chip:

◆ Configurable 4, 3 or 2 voltage multiplier, generating LCD supply voltage VLCD, independent of VDD, programmable by instruction (external supply also possible)

◆ Temperature compensation of on-chip generated VLCD: ?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: 80 characters

■ Character generator ROM: 240 characters of 5 × 8 dots

■ Character generator RAM: 16 characters of 5 × 8 dots; 3 characters used to drive 120 icons, 6 characters used if icon blink feature is used in application

■ 4-bit or 8-bit parallel bus and 2-wire I2C-bus interface

■ 18 row and 60 column outputs
