STMICROELECTRONICS STM32H7S3I8T6 ARM MCU, STM32 Family STM32H7 Series Microcontrollers, ARM Cortex-M7F, 32 bit, 600 MHz, 64 KB

STM32H7S3I8T6 is a high-performance Arm® Cortex®-M7 32bit, 600MHz MCU. The Cortex-M7 core features a floating point unit (FPU) that supports Arm double-precision (IEEE 754 compliant) and single-precision data processing instructions and data types. The Cortex-M7 core includes 32Kbytes of instruction cache and 32Kbytes of data cache. It supports a full set of DSP instructions and a memory protection unit (MPU) to enhance application security. To improve application robustness, all memories feature error code correction. The device embeds peripherals allowing mathematical/arithmetic function acceleration. Typical applications are motor drive and application control, medical equipment, industrial applications: PLC, inverters, circuit breakers, printers, and scanners, alarm systems, video intercom, and HVAC, home audio appliances, mobile applications, Internet of Things, wearable devices: smart watches.
