Functional Description
The CY3210-PSoCEVAL1 Evaluation Kit demonstrates the function of PSoC 1 devices. Connect the
device to onboard peripherals such as potentiometer, LEDs, LCD, and RS-232. The board also has
additional features such as a general prototype area (bread board) and an ISSP programming
header. It provides different voltage domains; see

Power Supply System
The power supply system on this board is versatile. The kit can be powered in three ways: using a
MiniProg unit, DC wall adaptor, or a 9-V battery. The DC wall adaptor must be of 9 V to 12 V, 1-A
rating unit. The onboard voltage regulator converts input 9 V/12 V into 3.3 V/ 5 V. Selection between
3.3 V and 5 V is done using jumper JP3. When the jumper (shunt) is not connected, the regulator
gives the output voltage of 5 V; installing the jumper gives a 3.3-V output.
Note
Use only one power supply at a time. Do not use a power supply that is less than 7 V or
exceeds 12 V.
If the board needs to be powered via external 3.3-V or 5-V supply, the power input should be con-
nected to the VCC sockets of the J5 connector (
). The external voltage must be less than
5.5 V.
Warning
Any voltage input greater than 12 V connected on these headers will permanently dam-
age the board components.
