The 3.6 V upper limit is safe for Li-ion without an external LDO, though a clean rail is still recommended for the internal oscillator stability. ## Package and footprint — 32-LQFP with 7x7 mm body The 32-LQFP package with a 7x7 mm body and 0.8 mm pitch is a common footprint shared across the STM32L0 value-line density options. The 26 I/O are all accessible on the outer leads; no exposed pad underneath, so standard QFP soldering profiles apply. ## Lifecycle status — active, no near-term EOL concern For new designs, this means no forced redesign cycle from obsolescence in the next several years. The STM32L0 series has broad second-source availability through the STM32 ecosystem, though no pin-compatible second manufacturer exists — qualification of an alternate within the same family (e.g., a higher-density STM32L021) is the usual risk-mitigation path. For volume production or kitting, we can provide pricing tiers and lead-time estimates on request. The active lifecycle means no premium for last-time-buy inventory — standard market pricing applies.","metaTitle":"STM32L011K4T6TR ARM Cortex-M0+ MCU, 32 MHz, 16 KB Flash","metaDescription":"STM32L011K4T6TR 32-bit MCU from STMicroelectronics STM32L0 series.
