STMicroelectronics, 32bit ARM Cortex M7, STM32 Microcontroller, 280MHz, 128 kbyte Flash, 64-Pin LQFP

The STMicroelectronics devices are based on the high-performance Arm Cortex M7 32-bit RISC core operating at up to 280 MHz The Cortex M7 core features a floating point unit (FPU) which supports Arm double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H7B0xB devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security. STM32H7B0xB devices incorporate high-speed embedded memories with a flash memory of 128 Kbytes, around 1.4 Mbyte of RAM (including 192 Kbytes of TCM RAM, 1.18 Mbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced I/Os and peripherals connected to four APB buses, three AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memory access.
