4.3 Schematic and PCB Attentions

The minimum requirements (power, reset, and Vcore) with suggested values for MSPM0 hardware setup are shown in Figure 4-9.

  • Power pin: TI recommends adding 10uF and 0.1uF capacitors, which are used to remove AC noise on the power rail.
  • Reset pin: TI recommends adding a 47kR pullup resistor and a 10nF pulldown capacitor. This makes sure that the MSPM0 releases from reset, after the power rail is stabilized.
  • Vcore pin: This pin is used to stabilize the CPU voltage. For some MSPM0 devices, this pin is not included. If the pin is included, connect the pin to a 0.47uF capacitor.

Other considerations when drawing a schematic file are listed in Figure 4-10.

  • ROSC Pin: If users want to reach accurate high frequency clock with internal SYSOSC, then 0.1% resistor is suggested. Some low-cost devices cannot have this function.
  • VREF+/VREF- Pin:
    • If using an internal reference,then the G series require a 1uF capacitor between VREF+ and VREF- to support 4Msps ADC. For L or C series, then the capacitor is not required as the ADC speed is only support 200Ksps with internal Vref.
    • If using an external reference, then all the MSPM0 devices require a 1uF capacitor between VREF+ and VREF-.
  • Open-Drain IO: Open-Drain IO cannot output high voltage from the MCU side, so external pullup resistors are required, such as a 4.7kR capacitor.
  • Reset Pin: If reusing the reset pin as GPIO, I2C or UART, then the pullup resistor and the pulldown capacitor are still required. This makes sure that the MCU is released from reset state after the power is stable. TI recommends reducing the resistor and capacitor, such as using a 2.2kR pullup resistor and 10pF pulldown capacitor.
  • PA18: PA18 is the invoke pin to enter bootloader. Make sure this pin is not in pullup or affected by noise or analog signals with this pin floating. Otherwise, the device enters the bootloader instead of the application code. More details and a software option to change and disable the invoke pin in sysconfig are shown in Section 7.4.
