MSP430F5437A: Need the reason why during flash write current consumption is reduced?

Part Number: MSP430F5437A

Hi,

We are doing segment erase  in flash and after it is completed by checking busy bit, we are doing Byte-Word write, in data section .infoB.

We repeat the above 6 times and then giving a delay of 4 secs. During this delay of 4 secs it is consuming 10 mA and while erasing and writing it is consuming around 7 mA.

Is there any internal modules of MSP430 are switched off to execute Flash operation ? Please clarify what may be the reason for reduce in current consumption?

Thanks,

Ayyappan M

  • Ayyappan,

    do me this sounds like the flash charge pump delivering the voltage for erase and program is still enabled. Maybe you can share the code for a more detailed check.

    Also question is at which frequency you're operating when you consume 10mA.

    Best regards,
