The STM32L422xx devices are 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 that 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 STM32L422xx devices embed high-speed memories (flash memory up to 128 Kbyte, 40 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 STM32L422xx devices embed several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, proprietary code readout protection and Firewall. The devices offer two fast 12-bit ADC (5 Msps), two comparators, one operational amplifier, 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 12 capacitive sensing channels are available. They also feature standard and advanced communication interfaces, namely three I2Cs, two SPIs, three USARTs and one Low-Power UART, one USB full-speed device crystal less. The STM32L422xx devices embed an AES hardware accelerator. The STM32L422xx operates in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V VDD power supply. A comprehensive set of power-saving modes makes possible the design of low-power applications. Some independent power supplies are supported: analog independent supply input for ADC, OPAMP and comparator. A VBAT input makes it possible to backup the RTC and backup registers. The STM32L422xx family offers six packages from 32 to 64-pin packages. https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2020-06-18 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2021-04-04 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2021-05-21 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2021-07-13 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2021-12-05 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2022-04-17 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2022-06-13 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2022-06-22 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2023-03-24 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2023-08-01 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2023-09-15 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2023-12-12 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-04-05 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-05-01 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-06-14 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-09-19 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-09-27 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-10-05 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-10-23 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-11-19 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-12-16 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2024-12-25 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2025-06-05 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2025-07-31 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2025-11-07 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2025-12-05 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2026-05-23 https://elecena.pl/product/16977617/stm32l422tby6tr-ultra-low-power-with-fpu-arm-cortex-m4-mcu-80-mhz-with-128-kbytes-of-flash-memory-usb 2026-07-09
