The recommended operating voltage range for STK14C88-3NF45I is 2.7V to 3.6V.
It is recommended to power up the VCC pin first, followed by the VIO pin. During power-down, the VIO pin should be powered down first, followed by the VCC pin.
The maximum clock frequency supported by STK14C88-3NF45I is 104 MHz.
A simple reset circuit can be implemented using a resistor, capacitor, and a voltage regulator. The reset pin should be connected to VCC through a resistor and a capacitor to ground.
The JTAG pins on STK14C88-3NF45I are used for debugging and programming the device. They can be used to connect to a JTAG interface for debugging and programming.
