PRODUCTION DATA.
デバイスごとのパッケージ図は、PDF版データシートをご参照ください。
The oscillator is enabled by connecting the appropriate fundamental 5–20 MHz resonator/crystal and load capacitors across the external OSCIN and OSCOUT pins as shown in section (a) of the figure below. The oscillator is a single stage inverter held in bias by an integrated bias resistor. This resistor is disabled during leakage test measurement and HALT mode.
NOTE
TI strongly encourages each customer to submit samples of the device to the resonator/crystal vendors for validation. The vendors are equipped to determine what load capacitors will best tune their resonator/crystal to the microcontroller device for optimum start-up and operation over temperature/voltage extremes.
An external oscillator source can be used by connecting a 1.5V clock signal to the OSCIN pin and leaving the OSCOUT pin unconnected (open) as shown in section (b) of the figure below.
NOTE
In figure (a), The values of C1 and C2 should be provided by the resonator/crystal vendor.
In figure (b), Kelvin_GND should not be connected to any other GND.
