STM32F723ZC数据手册ST中文资料规格书

描述 Description

The STM32F722xx and STM32F723xx devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 216 MHz frequency. The Cortex®-M7 core features a single floating point unit (SFPU) precision which supports Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances the application security.
The STM32F722xx and STM32F723xx devices incorporate high-speed embedded memories with a Flash memory up to 512 Kbytes, 256 Kbytes of SRAM (including 64 Kbytes of data TCM RAM for critical real-time data), 16 Kbytes of instruction TCM RAM (for critical real-time routines), 4 Kbytes of backup SRAM available in the lowest power modes, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, a 32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memories access.
All the devices offer three 12-bit ADCs, two DACs, a low-power RTC, thirteen general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers, a true random number generator (RNG). They also feature standard and advanced communication interfaces.
Advanced peripherals include two SDMMC interfaces, a flexible memory control (FMC) interface, a Quad-SPI Flash memory interface.
The STM32F722xx and STM32F723xx devices operate in the –40 to +105 °C temperature range from a 1.7 to 3.6 V power supply. Dedicated supply inputs for the USB (OTG_FS and OTG_HS) and the SDMMC2 (clock, command and 4-bit data) are available on all the packages except LQFP100 and LQFP64 for a greater power supply choice.
The supply voltage can drop to 1.7 V with the use of an external power supply supervisor. A comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F722xx and STM32F723xx devices offer devices in 7 packages ranging from 64 pins to 176 pins. The set of included peripherals changes with the device chosen.
These features make the STM32F722xx and STM32F723xx microcontrollers suitable for a wide range of applications.
