It handles sensor polling, PID loops, and communication protocol stacks without breaking a sweat, but it is not meant for heavy DSP or video. The Cortex-M0+ is a single-cycle I/O and interrupt-friendly core, so the 32 MHz clock translates to responsive GPIO toggling and low-latency ADC reads. For a battery-powered datalogger or a wireless sensor node, this speed tier keeps the active duty cycle short and the sleep current dominant. ## 128 KB Flash and 6 KB EEPROM — firmware and calibration storage The separate 6 KB EEPROM is a real advantage: calibration constants, device serial numbers, and configuration parameters live in true EEPROM cells rated for 100k erase/write cycles, independent of the Flash sector-erase granularity. That means no wear-leveling code needed for frequently updated data. The 1.65 V minimum supply is the key spec for single-cell alkaline or Li-ion designs. A CR2032 coin cell discharges to about 2.0 V; the STM32L071CBT6 keeps running down to 1.65 V, extracting nearly all the cell's energy. At the high end, 3.6 V covers a Li-ion cell fully charged (4.2 V is outside the range, so a small LDO is still needed for Li-ion — but the wide window simplifies rail design for primary cells). ## Active lifecycle — no EOL worry for new designs The base product number is STM32L071, and the series is STM32L0 — a mature, well-supported family with no imminent EOL signals. ## 48-LQFP package — hand-solderable, 37 I/O The 48-LQFP package with a 7x7 mm body is a standard gull-wing leaded package. It is easy to hand-solder for prototypes and rework-friendly in production. The 37 I/O lines are enough for a keypad, a small TFT display, or a handful of sensors and actuators.","metaTitle":"STM32L071CBT6 STMicroelectronics MCU, 32MHz, 128KB Flash","metaDescription":"STM32L071CBT6 ARM Cortex-M0+ 32-bit MCU, 32MHz, 128KB Flash, 20KB RAM, 6KB EEPROM, 1.65V-3.6V, -40°C to 85°C.
