The STM32L0x3 USB and LCD line of Cortex M0+ based MCUs offers crystal-less USB 2.0 FS (supporting charger detection and link power management), LCD driver (4x52 or 8x48), 16 capacitive touch keys and a true random number generator (TRNG).

Autonomous peripherals, real-time clock and an ultra-low-power 12-bit ADC with 48 µA budget consumption at 100 Ksps offload the CPU and make the devices more efficient. Specific low power timers guarantee lowest power consumption with cyclic wakeup.

The STM32L0x3 line offers up to 192 Kbytes of Flash memory, up to 20 Kbytes of RAM and up to 6 Kbytes of embedded EEPROM and comes in 32- to 100-pin packages in UQFN, LQFP, BGA and WLCSP.

AES 128-bit hardware encryption is available on STM32L063 and STM32L083. AES 256-bit, DES, 3DES, RSA and ECCC are supported by a specific software library.
