The latest additions to the STM32 family, the STM32F7x0 and H7x0 Value Line microcontrollers (MCU) from STMicroelectronics, give extra flexibility to create affordable performance-oriented systems including real-time IoT devices, without compromising features or cyber protection.
These new 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, with up to 2Mbyte Flash and up to 1Mbyte RAM, supported by the same ecosystem with the same easy-to-use tools.
The Value Lines retain powerful STM32F7 and H7 features, such as the state-of-the-art peripherals, hardware accelerators, and the real-time architecture with ultra-fast internal buses, short interrupt latency, and fast (~1ms) boot-up. The MCUs are also energy efficient, with flexible power modes, gated power domains, and on-chip power management that simplify design and reduce BOM cost.
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 STM32F730, STM32F750, and STM32H750 Value Line MCUs are in production, in various LQFP and BGA package options from 64-pin to 240-pin. Prices start from $1.64 for the STM32F730, $2.39 for the STM32F750 and $2.69 for the STM32H750 for orders of 1000 pieces.
