STM32F723ZET7 일반적인 설명

The STM32F723ZET7 is a high-performance microcontroller based on the Arm Cortex-M7 32-bit RISC core, operating at up to 216 MHz frequency. With its single floating point unit precision, this device supports single-precision data-processing instructions and data types. It also features a full set of DSP instructions and a memory protection unit, enhancing application security. The STM32F723ZET7 incorporates high-speed embedded memories, including up to 512 Kbytes of Flash memory, 256 Kbytes of SRAM, 16 Kbytes of instruction TCM RAM, and 4 Kbytes of backup SRAM. Additionally, it offers a range of enhanced I/Os and peripherals, connected to multiple buses and interconnects for efficient memory access. This device also includes three 12-bit ADCs, two DACs, a low-power RTC, general-purpose timers, PWM timers for motor control, and various communication interfaces. Evaluation and discovery kits, as well as a debugger/programmer, are available for development and testing purposes
