●

STM32L1: Designed for ultra-low-power applications that are energy-aware and seek

to achieve the absolute lowest power consumption. The L1 series maintains

compatibility with the F1 series.

–

Medium density devices are STM32L151xx and STM32L152xx microcontrollers

where the Flash memory density ranges between 64 and 128 Kbytes.

–

Medium+ density devices are STM32L151xx, STM32L152xx and STM32L162xx

microcontrollers where the Flash memory density is 256 Kbytes.

–

High density devices are STM32L151xx, STM32L152xx and STM32L162xx

microcontrollers where the Flash memory density is 384 Kbytes.
