The maximum operating temperature range for the TMS320F280220DAT is -40°C to 125°C.
The clock source for the TMS320F280220DAT can be configured using the Clock PLL Control Register (CLKPLLCTL) and the Clock Source Select Register (CLKSRCSEL). The default clock source is the internal oscillator, but it can be changed to an external clock source or the PLL clock.
The Boot Mode Select pins (BOOTMODE[1:0]) on the TMS320F280220DAT determine the boot mode of the device. The pins can be configured to select between different boot modes, such as booting from flash memory, booting from the serial peripheral interface (SPI), or booting from the quadrature encoder pulse interface (QEP).
The TMS320F280220DAT has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WDTCR). The watchdog timer can be used to reset the device in case of a software fault or hang.
The maximum current rating for the GPIO pins on the TMS320F280220DAT is 4mA per pin. However, the total current drawn from all GPIO pins should not exceed 100mA.
