China, July 2018 - a STM32 * product family, STM32 * product family, the STM32F7X0 and H7X0 Value Series (MCU) will provide developers with higher flexibility. This series is applicable to the development of prices, with performance-oriented real-time Internet of-connected equipment applications, without affecting the functionality or network security of the target application. The new high-performance and ultra-high performance STM32 value-for-money product lines are promoted in real-time Internet of Things equipment.
These new product lines streamline the embedded flash feature, only reserved the most basic important configuration, but can still run security startup code, sensitive code, and real-time routines on the on-chip, playing embedded flash memory time than external flash memory 25 There is a balance advantage (in the case of a cache failure). When necessary, the designer can extend the application system through the following two ways, the first method is to increase the external serial or parallel (up to 32-bit) memory, export various external interfaces and local execution (XIP) The advantage of functionality. The second method is to transplant application code to pin-compatible STM32F7 or STM32H7 series, which has built-in built-in 2 MByte flash memory and 1 MByte RAM, supports the same ecosystem, and a well-used development tool.
The new value-for-money product line retains powerful features of STM32F7 and STM32H7, such as the most advanced peripherals, hardware accelerator, and real-time architectures such as ultra-high-speed internal bus, short interrupt delay, fast start (~ 1 ms). Flexible power mode, gantry power domain, and on-chip power management technology simplifies design, reduce material listing, so that the new microcontroller maintains high energy.
In a safe high energy structure, the new value microcontroller Coremark® performance test has obtained the entry point for the innovation of Internet innovations in medical, industrial, consumption, etc. Since the highest working knot temperature reaches 125 ° C, even if the ambient temperature rises, the performance of the processor core and peripherals can still be used.
Getting Started STM32F730 Integrated Semiconductor's unique Executive Flash Code Zero Waiting Cycle ART AcceleratorTM memory acceleration technology, at 216 MHz running frequency, Coremark Bench is 1082 points. The peripheral interface includes an encrypted hardware accelerator, a USB 2.0 high-speed port with PHY, a CAN interface. The on-chip memory includes 64KB flash memory; 8kByte instructions for high performance access to internal or external memory; 256KB system RAM; 16KB + 64KB TCM (tight coupling memory) for performing the most critical routines and data.
The STM32F750 adds a TFT-LCD display controller for an integrated STMG's unique Chrom-ArtTM graphics accelerator. The on-chip function includes a hash algorithm hardware accelerator; two CAN interfaces; Ethernet MAC controllers; camera interfaces; two USB 2.0 interfaces with full speed PHY; 64K bytes flash; 4KByte data cache; 320KB system RAM; 6KB + 64KB TCM.
The high-end STM32H750 is 2020 points at 400MHz, and the hardware JPEG encoder / decoder is added to the TFT controller and the Chrom-ART accelerator to achieve faster GUI graphics processing performance. The peripheral interface includes a CANFD port; a built-in time trigger function and an additional CANFD port of the best op amp; a 16-bit ADC with a running rate of 3.6 msample / s. On-chip memory includes 128KB flash memory, 16KB instruction cache, 16KB data cache, 864KB system RAM, and 64KB + 128KB TCM, all have an ECC (Error Correction Code) feature, which is used to secure internal or external memory.
STM32F730, STM32F750 and STM32H750 value series microcontrollers have been officially put into production, using 64 pins to 240 pins, various LQFPs and BGA packages.
