The Cortex-M0+ core runs at 32 MHz. It handles sensor polling, control loops, and USB packets without a dedicated controller.
192 KB Flash fits a FreeRTOS kernel, a USB stack, and application code. The 20K x 8 SRAM (20 KB) is the tighter resource: a full-frame USB buffer plus sensor queues can eat half of it.
Not rated for extended automotive under-hood or downhole environments.
The core runs at 32 MHz, which is the maximum clock for this STM32L0 series Cortex-M0+ device.
Within the STM32L0 family, the STM32L073VZT6 offers the same 100-LQFP footprint and peripheral set but doubles the SRAM to 48 KB. For a drop-in replacement with identical memory, the STM32L071VZT6 is pin-compatible but lacks USB and the DAC.
STMicroelectronics publishes RoHS and REACH compliance declarations for the STM32L0 series. The 100-LQFP package is listed as RoHS-compliant and halogen-free per ST's standard material declarations. UL and IEC certifications are not typically issued for individual MCU packages — those apply at the end-equipment level.
