Product Details


Key Features

  • AEC Q100 grade 2 compliant for automotive applications
  • Single-chip LCD controller and driver
  • Extended operating temperature range from -40 °C to +105 °C
  • 100 segments and 18 backplanes allowing to drive any graphic with up to 1800 elements
  • Readout of RAM and registers is possible
  • Diagnostic features: Checksum on I2C and SPI bus
  • Frame frequency: programmable from 45 Hz to 360 Hz
  • 2960-bit RAM for storage (1800 bit for display data)
  • Two-line I2C-bus interface or four-line SPI bus
  • Multiplex drive mode 1:18 and 1:12
  • 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
