PCA2117 Automotive LCD driver for character displays Rev. 4 8 April 2015 Product data sheet 1. General description 1 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 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 2 I C-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 8 dot format) can be stored in three selectable RAM columns with 16 characters each. For a selection of NXP LCD character drivers, see Table 58 on page 97. 2. Features and benefits AEC Q100 grade 2 compliant for automotive applications Single-chip LCD controller and driver Extended operating temperature range from 40 C to +105 C 2-line display of up to 20 characters plus 200 icons or 1-line display of up to 40 characters plus 200 icons 5 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 V LCD Generation of intermediate LCD bias voltages Oscillator requires no external components (external clock also possible) Readout of RAM, CGROM, and all registers possible Diagnostic features: 2 Checksum on I C and SPI bus Frame frequency: programmable from 45 Hz to 360 Hz Display Data RAM (DDRAM): 80 characters 1.

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 most applications it is possible to use V as LCD supply DD voltage 3.
