Active production part for low-power embedded designs
It carries 16 KB of Flash program memory, 2 KB of SRAM, and 512 bytes of embedded EEPROM — enough for sensor-node firmware, configuration storage, and a modest data buffer without external memory.
Memory and peripheral budget for sensor and control applications
The 512 bytes of EEPROM are useful for calibration constants, node IDs, or fail-state logs that survive a power cycle without wear-leveling overhead. The 26 I/O lines in the 32-LQFP package provide enough GPIO for a keypad, a small character LCD, and sensor interrupts, while the integrated brown-out detect, POR, and watchdog reduce external supervision circuitry.
Supply rail and temperature range — battery and industrial fit
The 1.65 V minimum supply is the key enabler for single-cell battery designs: a near-depleted alkaline cell still holds the core operational. 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
STMicroelectronics lists the STM32L011K4T6TR with an active product status. 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.
