                      Product Overview

                      STM32L431RBY6TR is an ultra-low-power Arm® Cortex®-M4 32bit MCU+FPU. 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 STM32L431xx devices embed high-speed memories (flash memory up to 256Kbyte, 64Kbyte of SRAM), a quad SPI flash memories interface (available on all packages) and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32bit multi-AHB bus matrix.

                      • Ultra-low-power product type, 128KB of flash memory size
                      • 1.71V to 3.6V power supply range
                      • 28nA shutdown mode (5 wakeup pins)
                      • Batch acquisition mode (BAM), 4µs wakeup from stop mode
                      • Brown out reset (BOR), interconnect matrix
                      • 4 to 48MHz crystal oscillator, 32KHz crystal oscillator for RTC (LSE)
                      • RTC with HW calendar, alarms and calibration
                      • Up to 21 capacitive sensing channels support touch key, linear and rotary touch sensors
                      • 64 pins CSP ECOPACK®2 package
                      • Industrial temperature range from -40 to 85°C (105°C junction)
