The STM32L443xx devices 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 STM32L443xx devices embed high-speed memories (256 Kbyte of Flash memory, 64 Kbyte 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 32-bit multi-AHB bus matrix. The STM32L443xx devices embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall. The devices offer a fast 12-bit ADC (5 Msps), two comparators, one operational amplifier, two DAC channels, an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, four general-purpose 16-bit timers, and two 16-bit low-power timers. In addition, up to 21 capacitive sensing channels are available. The devices also embed an integrated LCD driver 8x40 or 4x44, with internal step-up converter. They also feature standard and advanced communication interfaces. https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2020-07-23 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2021-04-04 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2021-05-21 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2021-12-05 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2022-04-17 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2022-06-13 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2022-06-22 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2023-03-24 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2023-08-01 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2023-10-03 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2023-12-12 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2024-06-05 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2024-09-01 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2025-07-30 https://elecena.pl/product/17079384/stm32l443rci6-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-256-kbytes-of-flash-memory-lcd-usb-aes-256-dfsdm 2025-09-15
