Microcontrollers Procurement Notes

Verify the complete part number against official STMicroelectronics documentation to ensure correct package type, temperature range, and tape-and-reel configuration. Confirm that the specific suffix matches the required manufacturing lot and quality standards. Cross-reference with the latest datasheet revision to validate peripheral availability and electrical characteristics before finalizing procurement specifications.

Microcontrollers Selection Notes

Select this component when application requirements demand high computational throughput with deterministic real-time performance. The inclusion of dedicated Data TCM RAM ensures critical routines execute without bus contention. Consider the extensive connectivity suite if system integration requires simultaneous Ethernet, USB, and industrial bus protocols. Ensure design compatibility with the 1.7 V to 3.6 V supply range and thermal constraints of the UFBGA package.

Microcontrollers Part Context

This device belongs to the STM32F745xx series, which shares architectural similarities with the STM32F746xx family. Both series utilize the Cortex-M7 core but differ in memory capacity and pin count configurations. The STM32F745xx series provides a balanced combination of processing power and peripheral richness, targeting cost-sensitive high-performance applications compared to the larger STM32F767xx or STM32F777xx variants.

Microcontrollers Replacement Considerations

Official substitutes within the same family include STM32F745VG and STM32F745VI, which offer identical core functionality but differ in package size and pin count. Verify pin compatibility and memory mapping before substitution. Other series like STM32F407 lack the Cortex-M7 architecture and associated performance enhancements.
