(1)

Operation above TJ = 105°C for extended duration will reduce the lifetime of the device.

See CalculatingUsefulLifetimesofEmbeddedProcessors for more information.

(2)

The VDDIO BOR voltage (VBOR-VDDIO[MAX]) in Electrical Characteristics determines the lower voltage bound for device operation. TI

recommends that system designers budget an additional guard band (VBOR-GB) as shown in Figure 7-1.

(3)

Internal BOR is enabled by default.

(4)

Supply ramp rate faster than this can trigger the on-chip ESD protection.

(5)

TI recommends VBOR-GB to avoid BOR resets due to normal supply noise or load-transient events on the 3.3-V VDDIO system

regulator. Good system regulator design and decoupling capacitance (following the system regulator specifications) are important to

prevent activation of the BOR during normal device operation. The value of VBOR-GB is a system-level design consideration; the voltage

listed here is typical for many applications.
