GENERAL DESCRIPTION
The PCF8820 is a low power CMOS LCD row/column
driver, designed to drive grey-scale/ ECB colour dot matrix
graphic displays at a multiplex rate of 1 : 67. In the partial
screen mode, only 8 rows are driven at a multiplex rate of
1 : 8.
This chip provides all the necessary display functions,
including on-chip generation of the LCD supply voltage
and LCD bias voltages. Consequently, fewer external
components are required and the power consumption is
low.
The PCF8820 interfaces with most microcontrollers and
communicates via a two-line bidirectional bus (I
2
C-bus).
All inputs are CMOS compatible.
Remark: the waveform generation for ECB colour is
identical to that used for grey-scale.
