Competitor’s BOR protection is in the 10-50µA range and usually deactivated in low-power modes to save power – this is not practical as a BOR condition can easily occur even in a low-power mode. Therefore, the BOR must always be on for maximum reliability. All F2xx devices, all F4xx devices, the F16x, F15x, F1xx2 and all future MSP430 devices have or will have zero-power BOR.
