STM32F411xC STM32F411xE

Description

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 data-

processing 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

Refer to Table 2: STM32F411xC/xE features and peripheral counts for the peripherals

available for each part number.

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

Figure 3 shows the general block diagram of the devices.
