Abstract
This evaluation board can be used to demonstrate and evaluate the
PCA8538 segment driver. This is a chip-on-glass LCD driver which can
drive up to 918 segments in MUX 1:9. The board contains only the
display module, some decoupling capacitors and some jumpers. The
jumpers can be used for interface selection (I
been provided as well, which makes it easy to connect the board to any
microcontroller and power supply, and start developing an application.

UM10726 NXP Semiconductors User manual PCA8538 evaluation board can either be generated by the internal charge pump or it can be supplied with a second supply voltage (pin 13 of connector P1). In that case the internal charge pump must be disabled. Jumper JP6 should be removed when using an external V supply voltage. - Page 6 UM10726 NXP Semiconductors User manual PCA8538 evaluation board Table 2.
