The STM32L0x3 USB and LCD line of Cortex M+ based MCUs offers crystal-less USB 2.0 FS (supporting charger detection and link power management), LCD driver (8x28), 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 64 Kbytes of Flash, up to 8 Kbytes of RAM and up to 2 Kbytes of embedded EEPROM and comes in 48- to 64-pin packages in LQFP and BGA.
AES 128-bit hardware encryption is available on the STM32L063. AES 256-bit, DES, 3DES, RSA and ECCC are supported by a specific software library.
