Price advantage of STM32F412VGT6 LQFP-100 single chip microcomputer

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 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.

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.
