製品概要

概要

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.

特徴
Core: Arm^® 32-bit Cortex^®-M7 CPU with FPU, adaptive real-time accelerator (ART Accelerator) and L1-cache: 8 Kbytes of data cache and 8 Kbytes of instruction cache, allowing 0-wait state execution from embedded Flash memory and external memories, frequency up to 216 MHz, MPU, 462 DMIPS/2.14 DMIPS/MHz (Dhrystone 2.1) and DSP instructions.
