The ARM microcontroller STM32F205RET6 series is based on a high-performance ARM® Cortex®-M3 32-bit RISC core with an operating frequency of up to 120 MHz. This series integrates high-speed embedded memory (Flash memory up to 1mbyte, up to 128kbytes of system SRAM), backup SRAM up to 4kbytes, and is connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix A wide range of enhanced I/Os and peripherals. These devices also feature an Adaptive Real-Time Memory Accelerator (ART accelerator?), an ARM microcontroller STM32F205RET6 that allows performance from flash to 0-wait-state program execution at CPU frequencies up to 120 MHz. This performance has been verified with the CoreMark™ benchmark. ARM microcontroller STM32F205RET6 all devices provide 3 12-bit adc, 2 dac, a low-power RTC, 12 general-purpose 16-bit timers, including 2 motor control PWM timers, 2 general-purpose 32-bit timers. A true digital random generator (RNG). They also have standard and advanced communication interfaces. ARM microcontroller STM32F205RET6 New advanced peripherals include an SDIO, an enhanced Flexible Static Memory Control (FSMC) interface (for devices provided in packages of 100 or more pins), and a camera interface for CMOS sensors . These devices also come with standard peripherals. ? Up to three I2Cs? Three SPIs, two I2Ss. For audio-like accuracy, the I2S peripheral can be clocked via a dedicated internal audio PLL, or synchronized via an external PLL. ? Four USARTs and two UARTs ? One USB OTG high-speed full-speed capability (with ULPI)? Second USB OTG (full-speed)? Two cans? Note: The STM32F205xx and STM32F207xx devices have an operating temperature range of -40 to +105°C and a supply voltage range of 1.8 to 3.6 V. On devices in the WLCSP64+2 package, if IRROFF is set to VDD, the supply voltage can be reduced to 1.7 V when the device is operated in the 0 to 70°C temperature range using an external power manager (see Section 3.16). A comprehensive set of power-saving modes allows the design of low-power applications. The STM32F205xx and STM32F207xx devices are available in various packages from 64 pins to 176 pins. The set of included peripherals varies with the selected device. These features make the STM32F205xx and STM32F207xx microcontroller series suitable for a wide range of applications:? Motor drives and application control? Medical equipment? Industrial applications: PLCs, inverters, circuit breakers? Printers, scanners? Alarm systems, video walkie-talkies, HVAC?
