STM32H7B3QI - 280MHz MCU

Download the STM32H7B3QI datasheet PDF. This datasheet also covers the STM32H7B3RI variant, as both devices belong to the same 280mhz mcu family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Includes ST state-of-the-art patented technology Core.
  • 32-bit Arm® Cortex®-M7 core with double-precision FPU and L1 cache: 16 Kbytes of data and 16 Kbytes of instruction cache allowing to fill one cache line in a single access from the 128-bit embedded flash memory; frequency up to 280 MHz, MPU, 599 DMIPS/ 2.14 DMIPS/MHz (Dhrystone 2.1), and DSP instructions Memories.
  • 2 Mbytes of flash memory with read while write support, plus 1 Kbyte of OTP memory.
  • ~1.4 Mbytes of RAM.
