STM32L412KBT6 Description
The STM32L412KBT6 device is an ultra-low-power microcontroller built around the powerful 32-bit RISC Arm? Cortex?-M4 core that can operate at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all Arm? single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions.
The STM32L412KBT6 device integrates high-speed memories, including Flash memory up to 128 KBytes and 40 KBytes of SRAM, a Quad SPI flash memories interface (available on all packages), and a wide array of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
The STM32L412KBT6 device includes a number of readout protection, write protection, proprietary code readout protection, and firewall protection techniques for embedded Flash memory and SRAM.
Two fast 12-bit ADCs (5 Msps), two comparators, one operational amplifier, a low-power RTC, a general-purpose 32-bit timer, and a motor control-specific 16-bit PWM timer, four general-purpose 16-bit timers, and two 16-bit low-power timers are all included in the devices.
Furthermore, there are up to 12 capacitive sensing channels available.
They also have both conventional and cutting-edge communication interfaces.
