        Hi,

        We are planning to use RTC clock with external oscillator (LSE) and a backup battery. I looked in Octavo Excel file with Octavo OSD32MP1 pins, and find out that PC15-OSC32_OUT pin is RSVD in Octavo package. Is the LSE integrated in OSD32MP1? Do we need external oscillator LSE when using RTC in VBAT mode?

        Thanks in advance,
        Nenad

          Nenad,

          32KHZ oscillator is not integrated inside the SiP. Please take a look at Table 5-6 in OSD32MP1 datasheet: https://octavosystems.com/docs/osd32mp15x-datasheet/. We will update the pin mapping table to be less confusing. You will need an external 32KHZ oscillator on LSE.

          Best,

            Thanks Neeraj,
            We will put external 32KHz oscillator.
            Best wishes,
            Nenad
