PCF2113WU/2/F4,026

PCF2113WU/2/F4,026 2. Features

The PCF2113x is a low-power CMOS LCD controller and driver, designed to drive a dotmatrix LCD display of 2 lines of 12 characters or 1 line of 24 characters with 5 · 8 dotformat. All necessary functions for the display are provided in a single chip, includingon-chip generation of LCD bias voltages, resulting in a minimum of external componentsand lower system current consumption. The PCF2113x interfaces to mostmicrocontrollers via a 4-bit or 8-bit bus or via the 2-wire I2C-bus. The chip contains acharacter generator and displays alphanumeric and kana (Japanese) characters.The letter ‘x’ in PCF2113x characterizes the built-in character set. Various character setscan be manufactured on request.n Single-chip LCD controller/drivern 2-line display of up to 12 characters + 120 icons, or 1-line display of up to24 characters + 120 iconsn 5 · 7 character format plus cursor; 5 · 8 for kana (Japanese) and user-definedsymbolsn Icon mode for e.g. additional segment display section: reduced current consumptionwhile displaying icons onlyn Icon blink functionn Very low current consumption (20 m A to 200 m A):u Icon mode: < 25 m Au Power-down mode: < 2 m An On-chip:u Configurable 4, 3 or 2 voltage multiplier, generating LCD supply voltage VLCD,independent of VDD, programmable by instruction (external supply also possible)u Temperature compensation of on-chip generated VLCD: - 0.16 %/K to - 0.24 %/K(programmable by instruction)u Generation of intermediate LCD bias voltagesu Oscillator requires no external components (external clock also possible)n Display data RAM: 80 charactersn Character generator ROM: 240 characters of 5 · 8 dotsn Character generator RAM: 16 characters of 5 · 8 dots; 3 characters used to drive120 icons, 6 characters used if icon blink feature is used in applicationn 4-bit or 8-bit parallel bus and 2-wire I2C-bus interfacen 18 row and 60 column outputs
