MSPM0L1105: Technical discussion on the design of industrial electronic detonators using MSPM0L1105TRTRR

Part Number: MSPM0L1105

Hi TI Team

The following are some technical issues that the customer encountered when applying the MSPM0L1105TRTRR design. Please assist. Thank you.

Attached Figure 1 is the schematic diagram of the MCU part of the industrial electronic detonator product. Please answer the technical questions.

Does the PA0 of the MCU have a timer function in low-power mode? In low-power mode, it can automatically time. After the timing ends, it can trigger the IO port and output a high level.

Can the filter capacitors of the Vcre and VDD of the MCU be combined?

Is the NRST capacitor of the MCU necessary? Can it be omitted?

Attached Figure 2 is the functional description of the low-power timer of the MCU that our company has adopted. Please check whether the MSPM0L1105TRTRR meets the requirements.
