The maximum clock frequency of the MSP430F2013TN is 16 MHz, but it can be overclocked to 20 MHz with reduced voltage and temperature range.
To use an external crystal oscillator, set the XT2OFF bit in the FLLUNLOCK register to 0, and configure the XT2 pins as input pins. Then, connect the crystal oscillator to the XT2 pins and ensure the correct load capacitors are used.
The minimum voltage required for the MSP430F2013TN to operate is 1.8V, but it is recommended to operate at 2.2V or higher for optimal performance and to ensure all peripherals function correctly.
To reduce power consumption on the MSP430F2013TN, use the low-power modes (LPM0-LPM4), reduce the clock frequency, turn off unused peripherals, and use the built-in brown-out reset (BOR) to detect and respond to voltage drops.
No, the MSP430F2013TN is not 5V tolerant and should not be used with a 5V power supply. The maximum recommended voltage is 3.6V, and exceeding this voltage can damage the device.
