STM32L071 in STM32 Family
The STM32L071 sub-family by STMicroelectronics belongs to the STM32L0 series, designed around the ultra-efficient 32-bit Arm Cortex-M0+ core. Operating at 32 MHz, these microcontrollers focus on power-sensitive applications where energy consumption is critical. They integrate up to 192 Kbytes of Flash and 20 Kbytes of RAM, providing a balanced performance-to-power ratio for battery-operated devices requiring a small footprint and high reliability across the industrial and consumer electronics sectors.

Comparing specs that differ across variants.
| Part Number | I/O Pins | Package | ADC/DAC | Flash | Stock |
|---|---|---|---|---|---|
| STM32L071RBT6 (STMicroelectronics) | 51 | LQFP-64 | A/D 16x12b | 128KB | 16,375 |
| STM32L071CBT6 (STMicroelectronics) | 37 | LQFP-48 | A/D 13x12b | 128KB | 784 |
| STM32L071KZT6 (STMicroelectronics) | 25 | LQFP-32 | A/D 10x12b | 192KB | 1,802 |
| STM32L071KZU6 (STMicroelectronics) | 25 | UFQFN-32 | A/D 10x12b | 192KB | 11,465 |
Variants in the STM32L071 sub-family primarily differ based on Flash memory density, ranging from 64 KB to 192 KB, and package pin counts from 32-pin LQFP/UFQFPN to 100-pin TFBGA configurations. Certain models, like the STM32L071K series, offer smaller footprints for space-constrained PCB designs, while 'Z' suffix versions provide higher GPIO counts. Part numbers also specify temperature ratings and packaging types such as tray or tape-and-reel.
