STM32L4 series of ultra-low-power and performance MCUs

STM32L412/422, STM32L432/442 & STM32L452/462 devices extend the ultra-low-power portfolio and performance with an Arm^® Cortex^®-M4 core with DSP and floating-point unit (FPU) at 80 MHz.

The STM32L422 portfolio offers from 64 to 128 Kbytes of Flash and from 32-to 64-pin packages.
The STM32L432 portfolio offers from 128 to 256 Kbytes of Flash in very small plastic package QFN-32 (5 x 5 mm).
The STM32L452 portfolio offers from 256 to 512 Kbytes of Flash and from 48-to 100-pin packages.
