I plan on using MSP430F5636IPZ from Texas Instruments as my microcontroller in a project which I am currently working on. The MCU comes with a RTC_B (Real Time Clock) with Battery Backup capability. According to this article : "" https://www.ti.com/lit/an/slaa665b/slaa665b.pdf "" which I found for hardware implementation considers the usage of MSPTS430PZ100USB target board and MSP-EXP430F5529LP LaunchPad kit interface, which I believe is a beginners kit which I don't need since MSP430F5636IPZ is a single chip MCU which I am trying to design on a PCB board.
Can somebody help me to understand the hardware design listed in the article and how I can implement it in my design?
From reading the datasheet, I figured out that pin 87(Vbat) and pin 88(Vbak) are used to implement the battery backup along with RTC_B module (including a 32.768 KHz crystal oscillator).
Please Help!!
