Product data sheet Rev. 4 — 8 April 2015 2 of 107 NXP Semiconductors PCA2117 Automotive LCD driver for character displays Character Generator ROM (CGROM): 240, 224, or 208 characters (5 8) depending on the selected RAM size Character Generator RAM (CGRAM): 16, 32, or 48 characters (5 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 A to 200 A): Power-down mode: < 2 A Icon mode: < 25 A 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 most applications it is possible to use VDD as LCD supply voltage 3.
