PCF85162

Universal LCD driver for low multiplex rates

Functional description

The PCF85162 is a versatile peripheral device designed to interface between any

microcontroller to a wide variety of LCD segment or dot matrix displays (see Figure 3). It

can directly drive any static or multiplexed LCD containing up to four backplanes and up to

32 segments.

The possible display configurations of the PCF85162 depend on the number of active

backplane outputs required. A selection of display configurations is shown in Table 4. All

of these configurations can be implemented in the typical system shown in Figure 4.

[1]

7 segment display has 8 elements including the decimal point.

[2]

14 segment display has 16 elements including decimal point and accent dot.
