Shenzhen Meiyuxin Technology Co., Ltd.【Electronic BOM distribution list】STM32L431RCT6 ARM microcontroller - MCU Ultra-low-power FPU Arm Cortex-M4 MCU 80 MHz 256 Kbytes Quality assurance New original! ! !

Product Description:

The STM32L431RCT6 device is an ultra-low-power microcontroller based on a high-performance Arm® Cortex®-M4 32-bit RISC core operating at up to 80 MHz. The Cortex-M4 core features floating point unit (FPU) single precision and supports all Arm® single precision data processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU) for enhanced application security.

The STM32L431RCT6 device embeds high-speed memory (up to 256 KB Flash, 64 KB SRAM), a Quad SPI Flash interface (for all packages) and extensive enhanced I/O and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.

The STM32L431RCT6 devices embed several protection mechanisms for embedded Flash memory and SRAM: read protection, write protection, proprietary code read protection and firewall.

STM32L431RCT6 These devices provide a fast 12-bit ADC (5 Msps), two comparators, an operational amplifier, two DAC channels, an internal voltage reference buffer, a low-power RTC, a general-purpose 32-bit timer, a dedicated 16-bit PWM timers for motor control, four general-purpose 16-bit timers and two 16-bit low-power timers. Additionally, up to 21 capacitive sensing channels are available. They also have standard and advanced communication interfaces.

• Three I2C

• Three SPIs

• Three USARTs and one low-power UART.

• One SAI (Serial Audio Interface)

• An SDMMC

• a can

• One SWPMI (Single Wire Protocol Master Interface)

The STM32L431RCT6 operates in the temperature ranges of -40 to +85 °C (+105 °C junction), -40 to +105 °C (+125 °C junction) and -40 to +125 °C (+130 °C junction) ) temperature range from 1.71 to 3.6 volt supply. A comprehensive set of power saving modes allows the design of low power applications. Partial independent power support: analog independent power input ADC, DAC, OPAMP and comparator. VBAT input allows backup of RTC and backup registers.
