Quiesent current for MCU S912ZVML64F1MKHR

[vijay_anandk]

Hi,

I am vijay. I am using S912ZVML64F1MKHR microcontroller for one of my project application.

I need to now the quiesent current for S912ZVML64F1MKHR.

Can anybody send me the quiesent current of this MCU.

I was not able to find in datasheet.

Hi,

Check the A.1.11 Supply Currents section of the S12ZVM reference manual, starting page 762.

Regarding the stop mode here is some code for CAN wake-up. I hope it helps you.

In your MSCAN initialization routine, you need to add the following:

       CAN0CTL0_WUPE = 1;   /* Enable WAKEUP */      

    CAN0RIER_WUPIE = 1;  /* Enable wake-up interrupt */      

    CAN0CTL1_WUPM = 0;   /* Wake up mode: any dominant level */

Before the MCU is commanded to go to sleep, you need to request the module to enter sleep:

       CAN0CTL0_SLPRQ = 1;              /* MSCAN enter sleep mode */

       while (!(CAN0CTL1_SLPAK));       /* Wait for sleep mode acknowledge */

Then, you can drive the MCU into STOP mode with:

       asm(andcc #0x7F);    /* Enable STOP mode */

       EnableInterrupts;    /* Enable interrupts */
    asm{STOP};           /* Enter STOP mode */

At the MSCAN wakeup interrupt service request, you need to clear the wakeup flag

       CAN0RFLG_WUPIF = 1;  /* Clear wakeup flag */

Hi,

you mean quiescent current = sleep mode?

Hi Martin,

Yes i wants to know the Quiesent current in sleep mode and in Normal mode for S912ZVML64F1MKHR.

Hi Martin,

Thanks for your guidance.

I understood now from the datasheet.

sleep mode is rather stop mode described.

You can download the example code posted on our community space:

It was tested on S12ZVM EVB board. After you program the micro, disconnect the BDM and push the reset button. After reset, the micro will enter Stop mode. It can be waken-up with push button SW3  (aka "UP) which is connected to IRQ pin. After the push, MCU will exit Stop mode, go to ISR which will be indicated by few LED blinks and after that the MCU goes into Stop mode again.
