Potentiometer and DIP Switches
There are 8-bit general purpose dip switches (S3) provided for the user. A general purpose potenti-
ometer (R47) is provided next to the dip switches. This potentiometer can be routed to the chip using
the GPIO pins. The second potentiometer (R46) is specifically meant to control the contrast for the
LCD daughter card in the LCD1 slot.

Headers and Jumpers
Component
V - Vdd pin: This pin can provide a maximum of 50 mA at 5V to an external
board only when the input to the board is 12V. For input voltages greater
than 12V do not use this pin to power another board. This pin is only to
source the current. DO NOT SUPPLY POWER TO THIS PIN FOR POWERING
THE CY8CPLC20 DEVICE. Note that the PWR jumper (JP1) needs to be con-
nected to enable this functionality.
G - Gnd Pin: This pin can provide the ground reference to an external board.
This pin connects to the ground pin of the external board.
D - I2C Data (SDA): This is the data line for the I2C communication. This pin
is directly connected to the CY8CPLC20 device
C - I2C Clock (SCL): This is the clock line for the I2C communication. This
pin is directly connected to the CY8CPLC20 device.
R – Reset: Connecting this pin to an external board enables the
CY8CPLC20 chip to be reset by an external board. Note that the RES
jumper needs to be connected for enabling this functionality.
These dip switches are general purpose and can be routed to any port of
the CY8CPLC20 chip.
This is a variable resistor that connects to the VR header. It can be used to
generate a voltage between +5V and GND.
Adjusting this potentiometer adjusts the contrast on the LCD Daughter
Card.
