The STM32L151/152 devices extend the ultra-low-power concept with no compromise on performance, using the Cortex-M3 core and a flexible CPU clock from 32 kHz up to 32 MHz. As well as the dynamic run and low-power run modes, two additional ultra-low-power modes bring you very low power consumption while keeping an RTC, backup register content and low-voltage detector.
The STM32L151/152 devices are designed for medical, industrial and consumer applications and feature an onboard fast
12-bit 1 MSPS ADC, USB 2.0 FS and capacitive touch sensing. You may extend the memory range using the SDIO and FSMC interfaces.
To reduce application cost and design, the STM32L151/152 offer an integrated LCD driver with up to 8 x 40 segments.
The STM32L151/152 portfolio offers from 32 to 512 Kbytes of Flash and from 48- to 144-pin packages.
