製品概要
概要
STM32H7Pxxx devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 520 MHz. The Cortex®-M7 core features a floating-point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H7Pxxx devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.
In addition to the CPU, all devices include a high-performance signal processing (HSP) unit capable of accelerating and off loading mathematical and signal processing tasks. Specific part numbers incorporate STMicroelectronics Neural‑ART Accelerator.
STM32H7Pxxx devices incorporate high-speed embedded memories with a dual-bank flash memory of 2 Mbytes, 736 Kbytes of RAM (including 320 Kbytes of TCM RAM, 416 Kbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced I/Os and peripherals connected to three APB buses, five AHB buses, a 32-bit multilayer AHB bus matrix, and a 64-bit AXI interconnect for internal and external memory access.
All the devices offer four ADCs, eight DACs, of which six dedicated to internal voltage comparators, eight fast voltage comparators, a filter for a digital microphone, a low-power RTC, four 32-bit timers, nine general-purpose 16-bit timers, three PWM 16-bit timers for motor control, two basic timers, five low-power timers, a true random number generator (RNG) and a HASH accelerator.
All devices also feature the following communication interfaces:
- Standard interfaces
- Three I2Cs and one I3C
- Five USARTs, five UARTs, and one LPUART
- Six SPIs, three with I2S in full-duplex mode. To achieve audio class accuracy, the I2S peripherals can be clocked via an external clock to allow synchronization.
- One SDMMC interface
- A USB OTG full-speed
- Three FDCAN interfaces
- Advanced interfaces including
- A flexible memory control (FMC) interface
- An octo-SPI memory interface
Refer to Table 1 for the list of peripherals available on each part number.
STM32H7Pxxx devices operate in the -40 to +125°C ambient temperature range from a 1.71 to 3.6 V power supply. The supply voltage must stay above 1.71 V which is the embedded power voltage detector threshold. The device embeds an integrated voltage regulator to supply the core, or a high efficiency SMPS depending on the part number.
A comprehensive set of power-saving modes allows the design of low-power applications.
The CPU and domain states can be directly monitored on some GPIOs configured as alternate functions. STM32H7Pxxx devices are offered in several packages ranging from 100 to 176 pins/balls.
These features make the STM32H7Pxxx microcontrollers suitable for a wide range of applications:
- Industrial applications: PLC, inverters, circuit breakers
