    • any graphics of up to 408 segments/elements
  • 408-bit RAM for display data storage
  • Two sets of backplane outputs providing higher flexibility for optimal COG layout configurations
  • Up to 4 chips can be cascaded to drive larger displays with an internally generated or externally supplied VLCD
  • Selectable backplane drive configuration: static, 2, or 4 backplane multiplexing
  • LCD supply voltage:
    • Programmable internal charge pump for on-chip LCD voltage generation up to 5 x VDD2
    • External LCD voltage supply possible as well
  • Selectable 400 kHz I²C-bus or 3 MHz SPI-bus interface
  • Selectable linear temperature compensation of VLCD
  • Selectable display bias configuration
  • Wide range for digital and analog power supply: from 2.5 V to 5.5 V
  • Wide LCD voltage range from 4.0 V for low threshold LCDs up to 12.0 V for high threshold twisted nematic and Vertical Alignment (VA) displays
  • Display memory bank switching in static and 1:2 multiplex drive modes
  • Programmable frame frequency in the range of 45 Hz to 300 Hz; factory calibrated with a tolerance of ±3 Hz (at 80 Hz)
  • Selectable inversion scheme for LCD driving waveforms: frame or n-line inversion
  • Diagnostic features for status monitoring
  • Integrated temperature sensor with temperature readout
  • On chip calibration of internal oscillator frequency and VLCD
  • Laser marking at the back-side of the die for traceability of the lot number, wafer number, and die position on the wafer
