32-kHz and 24-MHz Crystal
PSoC 3 has an on-chip Real Time Clock (RTC), which can function in sleep. This requires an
external 32-kHz crystal, which is provided on board to facilitate RTC based designs. The PSoC 3
also has an option for an external MHz crystal in applications where the IMO tolerance is not
satisfactory. In these applications, the board has a 24-MHz crystal to provide an accurate main
oscillator.
PSoC 3 Development Kit Expansion Ports
The PSoC 3 Development Kit has two expansion ports, Port D and Port E, each with their own
unique features.
Port D
This is the miscellaneous port on the board. It is designed to handle CapSense based application
boards and digital application boards. The signal routing to this port adheres to the stringent
requirements posed to provide good performance CapSense. This port can also be used for other
functions and Expansion Board Kits (EBKs).
This port is not designed for precision analog performance. The pins on the port are functionally
compatible to port B of the PSoC Development Kit. So any project made to function on port B of the
PSoC Development Kit can be easily ported over to port D on this board. A caveat to this is that
there is no opamp available on this port; therefore, opamp based designs are not recommended for
use on this port.
