The 49-ball WLCSP package (3.29 x 3.26 mm) is the smallest footprint in the STM32L0 series, intended for space-constrained designs like wearables, sensor nodes, and medical patches where board area is tight and reflow profile must handle a wafer-level chip-scale package. ## Supply and temperature — the operating envelope Brown-out detect and POR are integrated, so external reset supervision is optional. ## Peripherals and I/O — what connects where The 13-channel 12-bit ADC captures analog sensor signals directly. DMA handles peripheral-to-memory transfers without CPU intervention, which matters for low-power polling loops. ROHS3 compliant, no exemptions sunset risk. This is a current-production MCU available through independent distribution.","metaTitle":"STM32L071CZY6TR ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STM32L071CZY6TR 32-bit MCU with ARM Cortex-M0+ core, 32 MHz speed, 192 KB Flash, 20 KB RAM, 6 KB EEPROM.
