11. Static characteristics
11.1 General operating conditions
[1] Typical ratings are not guaranteed. The values listed are for room temperature (25 C), nominal supply voltages.
[2] Including bonding pad capacitance. Based on simulation, not tested in production.
[3] The V
DD
supply voltage must be 1.9 V or above when connecting an external crystal oscillator to the system oscillator. If the V
DD
supply
voltage is below 1.9 V, an external clock source can be fed to the XTALIN by bypassing the system oscillator or the other clock sources
mentioned above can be used.
