The maximum clock frequency for the MSP430F2001TN is 16 MHz, but it can be overclocked up to 20 MHz with reduced reliability and increased power consumption.
To use an external crystal oscillator, connect the crystal to the XIN and XOUT pins, and configure the UCSCTL6 register to select the external clock source. Also, ensure that the MCLK frequency is set to the desired frequency using the UCSCTL1 register.
The minimum voltage required for the MSP430F2001TN to operate is 1.8V, but it is recommended to operate at a minimum of 2.2V for reliable operation.
To reduce power consumption on the MSP430F2001TN, use the low-power modes (LPM3, LPM4, etc.) by configuring the SCG0 and SCG1 registers. Also, disable unused peripherals and reduce the clock frequency to minimize power consumption.
No, the MSP430F2001TN is not 5V tolerant and should not be used with a 5V power supply. The recommended operating voltage range is 1.8V to 3.6V.
