DESCRIPTION

The μPD16686 and 16687 are controller/drivers which include display RAM for full-dot LCDs that can provide a four-level gray scale display. These ICs are able to drive full-dot LCDs that contain up to 128 x 128 dots.

FEATURES

? μPD16686: COM outputs configured on both sides of chip

? μPD16687: COM outputs configured on one side of chip

? LCD controller/driver with on-chip display RAM

? Can operate using single power supply (logic system) in range from +1.7 to +3.6 V.

? On-chip booster: Switchable from x2 to x9 modes

? Dot display RAM: 128 x 128 x 2 bits

? Selection of four levels of gray scales from among 33 possible levels

(four-frame rate control + 8 pulse width modulation)

? Full dot outputs: 128 segment outputs and 128 common outputs

? Static icon outputs: 20 segment outputs and 2 common outputs (same signal is output)

? Serial data input and 8-bit parallel data input (i80 series interface and M68 series interface)

? On-chip voltage divider resistor

? 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 oscillator
