ST STM32F722RCT6

ARM® Cortex®-M7216MHz256KB（256K x 8）

Overview

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: up to three I2Cs, five SPIs, three I2Ss in half duplex mode, four USARTs plus four UARTs, an USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ULPI only for the LQFP64 and LQFP100 packages and with the integrated HS PHY for the LQFP144 and UFBGA176 packages), one CAN, two SAI serial audio interfaces and two SDMMC host 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.
