Description

STM32F412XE/G devices are based on the high-performance Arm? Cortex? -M4 32-bit RISC core operating at a frequency of up to 100 MHz. Their 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.

STM32F412XE/G devices belong 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 even more power consumption saving during data batching.

STM32F412XE/G devices incorporate high-speed embedded memories (up to 1 Mbyte of Flash memory, 256 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix.

All devices offer one 12-bit ADC, a low-power RTC, twelve general-purpose 16-bit timers, two PWM timers for motor control and two general-purpose 32-bit timers.

They also feature standard and advanced communication interfaces:

? Up to four I2Cs, including one I2C supporting Fast-Mode Plus

? Five SPIs

? Five I2Ss 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.

? Four USARTs

? An SDIO/MMC interface

? A USB 2.0 OTG full-speed interface

? Two CANs. In addition, STM32F412xE/G devices embed advanced peripherals:

? A flexible static memory controller interface (FSMC)

? A Quad-SPI memory interface

? A digital filter for sigma modulator (DFSDM), two filters, up to four inputs, and support of microphone MEMs.

STM32F412xE/G devices are offered in 7 packages ranging from 48 to 144 pins. The set of available peripherals depends on the selected package.

The STM32F412xE/G operates 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 modes allows the design of low-power applications.

These features make the STM32F412xE/G 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

? Wearable devices

? Connected objects

? Wifi modules
