The PCF8535 is a low power CMOS LCD row/column
driver, designed to drive dot matrix graphic displays at
multiplex rates of 1 : 17, 1 : 26, 1 : 34, 1 : 49 and 1 : 65.
Furthermore, it can drive up to 133 icons. All necessary
functions for the display are provided in a single-chip,
including on-chip generation of LCD bias voltages,
resulting in a minimum of external components and low
power consumption. The PCF8535 is compatible with
most microcontrollers and communicates via an industry
standard two-line bidirectional I
All inputs are CMOS compatible.
