Part Number: MSP430F6433
Hi Team,
Posting on behalf of our customer.
I'll share this E2E post with our customer so he can reply when needed.
We assemble MSPF430F6433 to our product.
I would like to make sure whether our design is correct or not.
Where does the power for Xin come from? Vasys is correct?
In other words, since the MSP430F6433 treats the oscillator circuit as an analog circuit, I’d like to know if it’s correct to connect it to the analog power supply and analog GND.
The following is an excerpt from Section 2.1 on page 99 of the link below, which states as follows:
"The PMM uses an integrated low-dropout voltage regulator (LDO) to produce a secondary core voltage (VCORE) from the primary one applied to the device (DVCC). In general, VCORE supplies the CPU, memories (flash and RAM), and the digital modules, while DVCC supplies the I/Os and all analog modules (including the oscillators). "
The following is an excerpt from Section 4.2 on page 134 of the link below, which states as follows:
"The analog modules of the device are supplied by the internal analog system voltage VASYS. The AUX module switches VASYS among the AVCC, AUXVCC1, and AUXVCC2 inputs. VASYS is also output on the VASYS pin, which must be connected to an external capacitor as specified in the device-specific data sheet."
