4.1    STM32L476

4.1.1  General Description

The STM32L476xx are the ultra-low-power microcontrollers based on the high performance

ARM Cortex-M4, 32-bit RISC core operating at a frequency of up to 80 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 STM32L476 embed high-speed memories (Flash memory up to 1 Mbyte, up to 128

Kbyte of SRAM), an extensive range of enhanced I/Os and peripherals connected to two

APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. The STM32L476 embed

several protection mechanisms for embedded Flash memory and SRAM: readout protection,

write protection, proprietary code readout protection and Firewall.

The devices offer fast 12-bit ADCs (5 Msps), an internal voltage reference buffer, a low-

power RTC, two general-purpose 32-bit timer, two 16-bit PWM timers dedicated to motor

control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The Micro

Controller support digital filter for external sigma delta modulators (DFSDM).

In addition, 1 capacitive sensing button is available.

They also feature standard and advanced communication interfaces.

▪      Two I2Cs (I2C1 connected internally to Sensors).

▪      Three SPIs (SPI1 connected internally to BLE and Serial Flash).

▪      Two USARTs, two UARTs.

▪      One SDMMC

▪      One CAN

▪      One USB OTG full-speed

The STM32L476xx operates in the -40 to +85 C (+105 C junction), -40 to +105 C

(+125 C junction) and -40 to +125 C (+130 C junction) temperature ranges from a 1.71 to

3.6 V power supply. A comprehensive set of power-saving modes allows the design of low

power applications.
