概述
The PCA2117 is a low-power Liquid Crystal Display (LCD) controller and driver. It is specifically designed to drive LCD dot-matrix displays of 2‑lines by 20 characters or 1‑line by 40 characters with 5 x 8 dot format. In addition 200 icons can be displayed. The chip contains a character generator and displays alphanumeric characters. The PCA2117 features an internal charge pump with internal capacitors for on-chip generation of the LCD driving voltage. To ensure an optimal and stable contrast over the full temperature range, the PCA2117 offers a programmable temperature compensation of the LCD supply voltage. The PCA2117 can be easily connected to a microcontroller by either the two-line I²C-bus or a four-line bidirectional SPI-bus.

Various character sets can be manufactured on request. In addition up to 48 user-defined symbols (5 x 8 dot format) can be stored in three selectable RAM columns with 16 characters each.

2-line display of up to 20 characters plus 200 icons or 1-line display of up to 40 characters plus 200 icons
5 x 7 character format plus cursor and user-defined symbols
Icon blink function
On-chip:
Programmable 4, 3, or 2 times voltage multiplier generating LCD supply voltage (external supply also possible)
Integrated temperature sensor with temperature readout
Selectable linear temperature compensation of on-chip generated VLCD
Generation of intermediate LCD bias voltages
Oscillator requires no external components (external clock also possible)
Readout of RAM and all registers possible
Diagnostic features:
Checksum on I²C and SPI bus
Frame frequency: programmable from 45 Hz to 360 Hz
Display Data RAM (DDRAM): 80 characters
Character Generator ROM (CGROM): 240, 224, or 208 characters (5 x 8) depending on the selected RAM size
Character Generator RAM (CGRAM): 16, 32, or 48 characters (5 x 8); ICON-RAM: 400 bit
Two-line I²C-bus interface or four-line SPI bus selectable through input pin
Inversion modes
n-line (n = 1 to 7) inversion
Frame inversion
Large supply voltage range: VDD1: 2.5 V to 5.5 V (chip can be driven with battery cells)
Analog supply voltage VDD2: 2.5 V to 5.5 V
LCD supply voltage VLCD: 4 V to 16 V
Direct mode to save current consumption for icon mode and multiplex drive mode 1:9 (depending on VDD2 value and LCD properties)
Power-down mode pin
Very low current consumption (20 μA to 200 μA):
Power-down mode: < 2 μA
Icon mode: < 25 μA
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 driver outputs is reduced. In this case, for many applications it is possible to use VDD as LCD supply voltage
