Description
General part information
STM32L422 Series
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.
