STM32H745 in STM32 Family
The STM32H745 sub-family by STMicroelectronics features a high-performance dual-core architecture combining an ARM Cortex-M7 core running up to 480 MHz with an ARM Cortex-M4 core running up to 240 MHz. This asymmetrical multiprocessing approach allows for efficient task separation, where real-time control and communication protocols can be isolated from complex application logic. These microcontrollers are engineered for demanding industrial, consumer, and medical applications requiring significant computational throughput and extensive integrated peripherals.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| STM32H745I-DISCO (STMicroelectronics) | I-DISCO | 282 |
| STM32H745XIH6 (STMicroelectronics) | XIH6 | 2,233 |
| STM32H745IIT6 (STMicroelectronics) | IIT6 | 9,142 |
Variants within the STM32H745 sub-family primarily differ based on their physical packaging and pin counts, ranging from LQFP100 to TFBGA240 options. These physical differences dictate the number of available I/Os and peripheral interfaces such as additional serial ports or memory buses. While core performance remains consistent, certain variants are packaged as Discovery kits, like the STM32H745I-DISCO, which include integrated sensors, external memory, and debugging hardware for rapid prototyping.
