Automotive LCD driver for character displays

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.
