The recommended operating voltage range for STK14C88-5C45M is 4.5V to 5.5V.
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 STK14C88-5C45M is 133 MHz.
A simple reset circuit can be implemented using a resistor, capacitor, and a voltage regulator. The reset pin should be tied to VCC through a resistor and a capacitor to ground.
The maximum current rating for the I/O pins of STK14C88-5C45M is 4 mA.
