2 Description
The 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 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 STM32F412
XE/G 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 to save even more power
consumption during data batching.
The STM32F412
XE/G incorporate high-speed embedded memories (up to 1 Mbyte of Flash
memory, 256 Kbyte 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 timer for motor control and two general-purpose 32-bit timers.
They also feature standard and advanced communication interfaces.
• Up to four I
2
Cs, including one I
2
C supporting Fast-Mode Plus
• Five SPIs
• Five I
2
Ss out of which two are full duplex. To achieve audio class accuracy, the I
2
S
peripherals can be clocked via a dedicate internal audio PLL or via an external clock to
allow synchronization.
• Four USARTs
• An SDIO/MMC interface
• An USB 2.0 OTG full-speed interface
• Two CANs.
In addition, the STM32F412xE/G embed advanced peripherals:
• A flexible static memory control 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.
The STM32F412xE/G are offered in 7 packages ranging from 48 to 144 pins. The set of
available peripherals depends on the selected package. Refer to Table 2: STM32F412xE/G
features and peripheral counts for the peripherals available for each part number.
The STM32F412xE/G operates in the – 40 to + 105 °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.
