2.2 Supported Platforms

The smart fuse driver and configuration package contains example implementations for a variety of different microcontrollers or processors. Additional implementations are routinely added, however a list of current architectures and the relevant development kits are shown in Table 2-1:

Table 2-1 Supported Platforms
Architecture Development Board Ecosystem Notes
Texas Instruments MSPM0G3507-Q1 LP-MSPM0G3507 Code Composer Studio Theia
STMicroelectronics STM32H723ZGT6 NUCLEO-H723ZG STM32CubeIDE

Additional device support can be added by implementing the relevant device level functions described in Section 2.3.

The HSS-HCMOTHERBRDEVM has generic SPI headers that can be used to plug in external SPI signals to the attached high-side switch daughter card. During development of the code examples and HCS platform drivers, the development boards listed below were used in tandem with the HSS-HCMOTHERBRDEVM for validation. An example of the LP-MSPM0G3507 evaluation module used in this configuration can be found below in Figure 2-2:
