Hello All, request to please help me out with the below issues-
1.For the part MSP430FR2032IPMR does the active mode current into Vcc also include current consumed by all the internal modules like references/ADC etc?
2.As per section 6.9.1 of datasheet on which pins are the internal 1.5v & 1.2v references appearing?
Hi Siddharth,
For Question 1, active mode means that all clocks are active, and according to Section 5.5 in the datasheet, all peripheral modules are turned on in the default settings. If you'd like current consumption per module (uA/MHz), please refer to Section 5.10.
For Question 2, Section 6.9.1 clearly states that the on-chip references are 1.5V (internal usage) and 1.2V (external usage). Looking at Figure 2-1 in the User's Guide, you can see EXTREFEN allows the 1.2V reference voltage to be buffered and output to VREF+ (P1.4 on MSP430FR2032 when ADC channel 4 is selected as the function). Internally, the 1.5V reference voltage goes to an ADC channel (ADC channel 13) and to VR+ on the ADC core.
Regards,
James
