STM32H750VBT6 - 480MHz Cortex-M7 MCU, 128KB Flash | STMicroelectronics

The STMicroelectronics STM32H750VBT6 is a high-performance 32-bit Arm Cortex-M7 microcontroller with double-precision FPU operating at up to 480 MHz, featuring 128 KB of flash and 1 MB of SRAM in a 100-pin LQFP (14x14 mm) package. A microcontroller (MCU) is a compact integrated circuit that combines a processor core, memory, and programmable I/O peripherals on a single die to govern a specific embedded operation. The STM32H750VBT6 sits at the top of the STM32H7 Value-Line hierarchy, which itself belongs to the broader STMicroelectronics STM32 family of 32-bit Arm Cortex-M microcontrollers, placing it well above mainstream families such as the STM32F4 in both clock speed and peripheral richness. Key features include the 480 MHz Cortex-M7 core with DP-FPU and L1 cache, 1 MB of SRAM paired with only 128 KB of internal flash (a deliberate value-line trade-off that encourages executing code from external memory or XSPI RAM), a hardware cryptographic accelerator for AES/DES/3DES/HASH/SHA, and a rich connectivity set with 46 communication interfaces including USART, SPI, I2C, FDCAN, USB OTG, Ethernet MAC, an SDMMC, a TFT-LCD controller, a DCMI camera interface, and the Chrom-ART graphics accelerator. The device operates from a 1.62 V to 3.6 V supply across -40 C to +85 C. Architecturally, the device integrates an MPU, an NVIC with hardware tail chaining, and four flexible power modes (Run, Sleep, Stop, Standby) managed through an internal SMPS-capable voltage regulator that can be configured to balance performance versus consumption. The Cortex-M7 superscalar pipeline with branch prediction delivers 2.14 DMIPS/MHz and a CoreMark score in the hundreds per MHz. Typical applications include industrial motor drives and power conversion, medical instrumentation, smart-home and audio hubs, and HMI/graphics systems where 480 MHz throughput, 1 MB on-chip RAM, and LCD/camera interfaces remove the need for external memory in many designs. Design consideration: with only 128 KB of internal flash, large applications must run from XSPI external memory or internal RAM, so budget code placement and boot configuration early in the project lifecycle.
