STMicroelectronics STM32F7x0 and STM32H7x0 Value Line microcontrollers

The STM32F7x0 and H7x0 Value Line microcontrollers (MCU) feature extra flexibility to create performance-oriented systems including real-time IoT devices.

The lines trim embedded Flash to the essential, still allowing secure boot, sensitive code and real-time routines to run safely on-chip, leveraging access times over 25 times faster than for external Flash (for cache miss). If needed, applications can scale-up either by adding off-chip serial or parallel (up to 32-bit) memories and leveraging the MCUs’ broad external interfaces and eXecute in Place (XiP) capability, or by porting to other pin-to-pin compatible STM32F7 or STM32H7 MCU lines.

The Value Lines retain powerful STM32F7 and H7 features, such as peripherals, hardware accelerators and the real-time architecture with ultrafast internal buses, short interrupt latency and fast (~1 ms) boot-up. They are also energy efficient, with on-chip power management, flexible power modes and gated power domains that simplify design.

With execution performance up to 2020 CoreMark at the heart of a secure and power-efficient architecture, the devices are the entry point to IoT innovation in medical, industrial and consumer applications. With up to 125°C as the maximum junction temperature, developers can leverage the full core and peripherals performance even when ambient temperature increases.

The entry-level STM32F730 delivers 1082 CoreMark performance running at 216 MHz aided by ST’s ART Accelerator for zero-wait-state execution from Flash. Features include cryptographic hardware acceleration, a USB 2.0 High Speed port with PHY and a CAN interface. There is a 64 KB Flash, 8 KB instruction and data caches for high-performance execution from internal or external memories, 256 KB of system RAM and 16 + 64 KB of tightly coupled memory (TCM) for critical routines and data.

The STM32F750 adds a TFT-LCD controller with ST’s Chrom-ART Graphics Accelerator. It has hardware acceleration for hash algorithms, two CAN interfaces, an Ethernet MAC, camera interface and two USB 2.0 interfaces with Full Speed PHY. There are 64 KB of Flash, 4 KB instruction and 4 KB data caches, 320 KB of system RAM and 16 + 64 KB TCM.

The high-end STM32H750 delivers 2020 CoreMark performance at 400 MHz and adds a hardware JPEG coder/decoder to the TFT controller and Chrom-ART Accelerator for fast GUI performance. There is also a CANFD port and additional CANFD with time-trigger capability, operational amplifiers and 16-bit ADCs running at up to 3.6 MS/s. The 128 KB Flash, 16 KB instruction and data caches, 864 KB system RAM and the 64 + 128 KB of TCM all feature ECC (error correction code) for safe execution from internal or external memory.
