Good Quality Stereo Audio Amplifier Ic - STM32F411RET6 ARM Microcontrollers MCU STM32 Dyn Eff MCU 512 K 100 MHz CPU – Shinzo

♠ Product Description

♠ Arm® Cortex®-M4 32b MCU+FPU, 125 DMIPS, 512KB Flash, 128KB RAM, USB OTG FS, 11 TIMs, 1 ADC, 13 comm. interfaces

The STM32F411XC/XE devices are based on the high-performance Arm® Cortex® -M4 32- bit RISC core operating at a frequency of up to 100 MHz. The Cortex®-M4 core features a Floating point unit (FPU) single precision which supports all Arm single-precision dataprocessing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

The STM32F411xC/xE belongs to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing to save even more power consumption during data batching.

The STM32F411xC/xE incorporate high-speed embedded memories (up to 512 Kbytes of Flash memory, 128 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.

All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.

• Up to three I2Cs

• Five SPIs

• Five I2Ss out of which two are full duplex. To achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization.

• Three USARTs

• SDIO interface

• USB 2.0 OTG full speed interface The STM32F411xC/xE operate in the – 40 to + 125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.

These features make the STM32F411xC/xE microcontrollers suitable for a wide range of applications:

• Motor drive and application control

• Medical equipment

• Industrial applications: PLC, inverters, circuit breakers

• Printers, and scanners

• Alarm systems, video intercom, and HVAC

• Home audio appliances

• Mobile phone sensor hub
