DESCRIPTION
The µPD16498 is a controller/driver which includes display RAM for full-dot LCDs that can provide a four-level gray scale display. This IC is able to drive full-dot LCDs that contain up to 128 x 128 dots.

FEATURES
• LCD controller/driver with on-chip display RAM
• Full dot outputs: 128 segment outputs and 128 common outputs
• Static icon outputs: 20 segment outputs and 2 common outputs (same signal is output)
• Can operate using single power supply (logic system) in range from 1.7 to 3.6 V.
• Selection of four levels of gray scales from among 33 possible levels (four-frame rate control + 8 pulse width modulation)
• Serial data input and 8-bit parallel data input (i80 series interface and M68 series interface)
• Dot display RAM: 128 x 128 x 2 bits
• On-chip booster: Switchable from x2 to x9 modes
• Selectable bias levels: 1/12 to 1/7 bias (normal display), 1/6 or 1/5 bias (partial display)
• Duty settings: 1/128 to 1/1 duty
• On-chip voltage divider resistor
• On-chip oscillator
