Part Number: MSP430FR5869 Hi
Do you have answer to the following question?
1.
What is input impedance of ADC?
2.
Do you have information when input current sink leads to more or less impact for ADC?
Or is it no matter as long as input current is kept…

Hi all, I would like to read and write data into MSP430FR5869 over SPI with slave mode. But the read process always return 0 or 255.
My source code on MSP430 as below:
//select spi gpio
P2SEL0 |= BIT4 | BIT5 | BIT6;
UCA1CTLW0…
Part Number: MSP430FR5869 Hi:
I'm using ADC12 in Repeat-signal-channel mode,the ADC12SHSx is 0, the clock source is SMCLK which is 8Mhz and adc clock divider is 1MHz.
And I'm using DMA to transfer adc result, the low power mode is LPM3.
For most…
Part Number: MSP430FR5869 hi,
i promote MSP430FR5869 to my customer cause they need ULP MCU with performance.
once they know the memory type is FRAM, they wondering will it affected by magnatic field easily(bit status inverse)?
as we know, FRAM has the…
Part Number: MSP430FR5869 Hi
We have following questions. Could you answer them?
1.
According to Table 6-1 in the datasheet, wake-up events of LPM3 are described as LF, I/O and Comp.
Does "I/O" mean digital IO and "Comp" mean Comparator_E?…
Part Number: MSP430FR5869 Hi Champs,
We are using VCC:1.9V and set AVCC=1.9V for ADC input.Also, VREF=AVCC setting.
but, output ADC full scalle value didn't up to 1.9V. This value show 1.2V. We also changed VREF=2.0V with internal REFVSEL to 2.0V…
Part Number: MSP430FR5869 Hi,
what is the minimum supply voltage of ADC of MSP430FR5869? I saw FR2111 requires at least 2V to operate ADC but I did not see this number in FR5869 datasheet. Also, if DVcc is 1.8V, which peripheral cannot run in this condition…
Part Number: MSP430FR5869 Hi Champ,
I would like to confirm possibility of PIN function change. C0 ->A0 after Active mode.
I have describe this step.
1: Pin1 : (P1.0/TA0.1/DMAE0/RTCCLK/A0/C0/VREF-/VeREF-) function assigned "C0" comparator mode and waiting…

Hi Champs,
I would like to make sure.
Even If we input supply voltage(=2.0V) with no F/W statement, the GPIO statement is "Lo" even this sytem add external pull up statement ?
I think this should be "Hi" when…
Part Number: MSP430FR5869 Other Parts Discussed in Thread: MSP-FET , MSP-FLASHER Hi Champs,
We would like to flash F/W with VCC=2.0V for FR5x.
Because, their connected module have to keep VCC=2.0V. Do you have any minimum voltage and current for FRAM device…
