LP-AM243: 1.8V SPI

Part Number: LP-AM243
Other Parts Discussed in Thread: AM2434,

Hello,

Is there a way to make the SPI bus on the AM2434 Launchpad a 1.8V signal instead of 3.3V?

  • Hi, 

    On the AM243x MCU this is possible by selecting the appropriate IO group and corresponding VDDSHVx power net. However, on the LP-AM243 for simplicity, the VDDSHVx are not routed separately, but instead joined to a single 3.3V IO power net. So you cannot change voltage to just one group. The power is also provided by a single regulator. 

    Let me know if that answers your question. 

    Thank you,

    -Randy
