• Display data RAM 80 × 128 bit
• 128 icons (row 80 can be used for icons in extended command set and when icon rows are enabled)
• Low power consumption; suitable for battery operated systems
• Interfaces: an 8-bit parallel interface, 3 or 4-line Serial Peripheral Interface (SPI) and High-speed I²C-bus
• On-chip:
  • Configurable voltage multiplier generating LCD supply voltage VLCD; an external VLCD is also possible
  • Linear temperature compensation of VLCD; 8 programmable temperature coefficients (extended command set); one fixed temperature coefficient which can be set as default by OTP programming (basic command set)
  • Generation of intermediate LCD bias voltage
  • Oscillator requires no external components
• OTP calibration for VLCD and accurate frame frequency
• External reset input pad
• External clock input possible
• Multiplex rate: 1:16 to 1:80 in steps of 8 when no icon row is used; with the icon row, steps of 16 can be used
