The STM32L0x2 USB line is a complement to the Access line offering in addition crystal-less USB 2.0 FS (BCD, LPM compliant), 16 capacitive touch keys and a true random number generator (TRNG).
As well as the STM32L0x1 line features, the STM32L0x2 offers autonomous peripherals, real-time clock, low-power time clock, hardware encryption and ultra-low-power 12-bit ADC with 48 µA budget consumption at 100 Ksps.
The STM32L0x2 series offers up to 64 Kbytes of flash, up to 8 Kbytes of RAM and up to 2 Kbytes of embedded EEPROM, and comes in 32- to 64-pin packages in UQFN, LQFP and WLCSP.
STM32L062 devices complete the STM32L0x2 line by proposing AES 128-bit hardware encryption on chip. To complete its cryptography capability, crypto libraries covering AES 256-bit, DES, 3DES, RSA and ECCC are available for all STM32 MCUs.
