                      Product Overview

                      STM32L432KCU6 is an ARM® based 32bit microcontroller. This ultra-low-power microcontroller is based on the high-performance Arm® Cortex®-M4 32bit RISC core operating at a frequency of up to 80MHz. 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. It embeds several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, proprietary code readout protection and firewall.

                      • 256Kb of flash memory, 80MHz maximum CPU frequency
                      • 1.71 to 3.6V operating voltage, batch acquisition mode (BAM)
                      • 32KHz crystal oscillator for RTC (LSE), internal 16MHz factory-trimmed RC (±1%)
                      • Internal 48MHz with clock recovery, 2 PLLs for system clock, USB, audio, ADC
                      • Up to 256Kb single bank flash, proprietary code readout protection
                      • USB 2.0 full-speed crystal less solution with LPM and BCD
                      • SWPMI single wire protocol host I/F, IRTIM (infrared interface)
                      • 14-channel DMA controller, true random number generator
                      • Industrial temperature range from -40 to 85°C
                      • 32-pin QFN package
