7 Parameter Measurement Information

SM470R1B1M-HT param_meas_tdz046.gif
A. For these values, see the Section 6.4.
B. All timing parameters measured using an external load capacitance of 150 pF unless otherwise noted.
Figure 7-1 Test Load Circuit

7.1 External Reference Resonator/Crystal Oscillator Clock Option

The oscillator is enabled by connecting the appropriate fundamental 4–10 MHz resonator/crystal and load capacitors across the external OSCIN and OSCOUT pins as shown in Figure 7-2 (a). 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. 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. Please note that external crystal mode is specified to function only within the temperature ranges of –40°C to 150°C. Above this recommended temperature range it is strongly recommended to use an external clock signal as shown in Figure 7-2 (b).

An external oscillator source can be used by connecting a 1.8-V clock signal to the OSCIN pin and leaving the OSCOUT pin unconnected (open) as shown in Figure 7-2b.
