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.
