MSP430F1232: DVCC rise time specification

Sh.Sasaki

Part Number: MSP430F1232


Hi experts,

Is there a specification for DVCC rise time of MSP430F1232?

I checked the data sheet of MSP430F1232, but there was no specification of "dVCC/dt".

I want to know the minimum and maximum DVCC rise time of this device.

Best regards,
Sasaki

    Hi Sasaki

    We recommend to power the device as soon as possible that make the time at critical voltage like 1.8v as short as possible. But normally we will add some capacitors or some  parasitic capacitor on the PCB to make the VCC to be stable that will decrease the rise time of the DVCC. So the DVCC rise time is mainly related with outside capacitor conditions and that is a tradeoff with noise immunity.

    Hi Gao-san,

    Thank you for your reply. This device does not have a defined power supply voltage rise time specification, but it means that the power supply will be turned on as soon as possible. I understand it.

    Best regards,
    Sasaki
