PCA8537
Automotive LCD driver for multiplex rates up to 1:8
8. Functional description
The PCA8537 is a versatile peripheral device designed to interface any microcontroller to
a wide variety of LCDs. It can directly drive any static or multiplexed LCD containing up to
352 elements.
8.1 Commands of PCA8537
The commands to control the PCA8537 are defined in Table 5. Any other combinations of
operation code bits that are not mentioned in this document can lead to undesired
operation modes of PCA8537.

8.1.1 Command: Initialize
This command generates a chip-wide reset which resets all command values to their
default values. After this command is sent, it is possible to send additional commands
without the need to re-initialize the interface. The reset takes 100 ns to complete.
