• Power on the board per the power-up sequencing. No voltage should be applied on the VPP_CORE and

VPP_MCU terminals during power up and normal operation.

• Load the OTP write software required to program the eFuse (contact your local TI representative for the OTP

software package).

• Apply the voltage on the VPP_CORE and VPP_MCU terminals according to the specification in Section

7.7.1.

• Run the software that programs the OTP registers.

• After validating the content of the OTP registers, remove the voltage from the VPP_CORE and VPP_MCU

terminals.

7.7.4 Impact to Your Hardware Warranty

You recognize and accept at your own risk that your use of eFuse permanently alters the TI device. You

acknowledge that eFuse can fail due to incorrect operating conditions or programming sequence. Such a failure

may render the TI device inoperable and TI will be unable to confirm the TI device conformed to TI device

specifications prior to the attempted eFuse. CONSEQUENTLY, TI WILL HAVE NO LIABILITY FOR ANY TI

DEVICES THAT HAVE BEEN eFUSED.
