NXP USA Inc. PCF2113DH/4,557

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 a 5 x 8 dot format. It provides all necessary functions for the display, 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
5x7 character format plus cursor; 5 x 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 VoD- 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 x 8 dots
Character generator RAM: 16 characters of 5 x 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
