The STMicroelectronics devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core features a floating point unit (FPU) which supports Arm® double-precision and single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances the application security. The STM32 devices incorporate high-speed embedded memories with a Flash memory up to 2 Mbytes, 512 Kbytes of SRAM (including 128 Kbytes of Data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM (for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest power modes, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memories access.

Up to 4 I2C interfaces (SMBus/PMBus)
Up to 4 USARTs/4 UARTs (12.5 Mbit/s, ISO7816 interface, LIN, IrDA, modem control)
Up to 6 SPIs (up to 54 Mbit/s), 3 with mixed simplex I2S for audio
2 x SAIs (serial audio interface)
3 x CANs (2.0B Active) and 2x SDMMCs
SPDIFRX interface
