Microcontrollers Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official STMicroelectronics documentation prior to integration. Ensure the ordering code matches the exact pin count and package type required for the PCB layout design.

Microcontrollers Selection Notes

Select this model for applications demanding high security alongside low power usage. The Cortex-M33 core supports DSP instructions suitable for signal processing tasks. Verify that the 100-pin LQFP package fits the mechanical constraints. Consider the 96 MHz maximum frequency against real-time processing requirements.

Microcontrollers Part Context

This component belongs to the STM32U3 family, which utilizes near-threshold voltage technology. It shares architectural similarities with other STM32U3 variants but offers specific memory sizes and peripheral sets. The VGI6 suffix denotes the 100-pin LQFP package configuration within the STM32U385xx product line.

Microcontrollers Replacement Considerations

Compatible substitutes within the same family include STM32U385VGT6 and STM32U385KGU6. These alternatives share identical core specifications but differ in package types such as UFBGA or UFQFPN. Verify pin compatibility before substitution.
