32-kHz and 24-MHz Crystal
PSoC 5LP has an on-chip real time clock (RTC), which can function in sleep. This requires an
external 32-kHz crystal, which is provided on the board to facilitate RTC-based designs. The PSoC
5LP also has an external MHz crystal option 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.
Protection Circuit
A reverse-voltage and over-voltage protection circuit is added at the expansion port on 5 V and 3.3 V
lines.
The protection circuit consists of two P-channel MOSFET on the power line allowing the power/cur-
rent to flow from input to output depending on the voltages applied at the external board connector.
Figure 2 and Figure 3 are protection circuits placed between EBK and the on board components on
the 5V and 3.3V line.
