The recommended operating voltage range for STK14C88-3NF35I is 2.7V to 3.6V.
The power-up sequence should be VCC first, then VIO, and then the clock signal. For power-down, the sequence should be reversed.
The maximum clock frequency supported by STK14C88-3NF35I is 133 MHz.
A simple reset circuit can be implemented using a resistor, capacitor, and a diode. The reset signal should be asserted for at least 10ms to ensure proper reset.
The maximum current rating for the I/O pins of STK14C88-3NF35I is 4mA.
