STMicroelectronics' new addition “STM32F7x0 and H7x0”provides cyber protection and affordable performance-oriented systems for IoT devices. Features like secure boot, sensitive code, flash size upto 2 Mbyte, upto 1Mbyte of RAM, flexible power modes, ultra-fast internal buses, short interrupt and on board safety management system makes STM32F7 and H7 to deliver high performance for IoT applications. For making it accessible for many other applications, interface or add off-chip serial or parallel (up to 32-bit) or with MCUs board and execute in place (Xip) capability.
STM32F7 & H7 is also an energy efficient as it have flexible power modes, gated power domains and on-chip power management, which also make its design simple and cheaper.
With execution performance up to 2020 CoreMark®[1] at the heart of a secure and power-efficient architecture, the new Value Line 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 216MHz aided by ST’s unique 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 64Kbyte Flash, 8KByte Instruction and data caches for high-performance execution from internal or external memories, 256KB of system RAM and 16kB+64KB of Tightly Coupled Memory (TCM) for the most critical routines and data.
The STM32F750 adds a TFT-LCD controller with ST’s proprietary 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 64Kbytes of Flash, 4Kbyte instruction and 4Kbyte data caches, 320KB of system RAM, and 16kB+64KB TCM.
The high-end STM32H750 delivers 2020 CoreMark performance at 400MHz and adds a hardware JPEG coder/decoder to the TFT controller and Chrom-ART Accelerator for even faster GUI performance. There is also a CANFD port and additional CANFD with time-trigger capability and best-in-class operational amplifiers and 16-bit ADCs running at up to 3.6Msample/s. The 128KByte Flash, 16KByte instruction and data caches, 864KByte system RAM and the 64kB+128KB of TCM all feature ECC (Error Correction Code) for safe execution from internal or external memory.
Mass production for all the three is started in different package types such as LQFP and BGA.
