Applications
The STM32L071VZT7 is designed for battery-powered IoT sensor nodes, smart meters, wearable devices, and wireless communication modules requiring long operational life from a small battery at supply voltages from 1.65 V to 3.6 V. Its 192 KB Flash, 6 KB EEPROM, and ultra-low-power Stop mode enable data-logging applications such as environmental monitors, industrial asset trackers, and medical diagnostic wearables that wake periodically from sleep, sample sensors via ADC, and transmit data over UART or USB. The 100-pin LQFP100 package with up to 87 GPIOs also suits control panels, building automation terminals, and portable test instruments where a rich I/O set is required alongside low-power operation.

Frequently Asked Questions
What is the maximum clock frequency and power consumption in Stop mode for the STM32L071VZT7?
The STM32L071VZT7 runs the ARM Cortex-M0+ core at up to 32 MHz and achieves ultra-low power consumption of approximately 0.29 µA in Stop mode with RAM retention. This combination of a 32 MHz maximum clock and sub-microampere standby current makes it suitable for battery-operated IoT nodes that wake periodically from sleep, process sensor data, and return to Stop mode to maximize runtime on a CR2032 or AA cell.
How much non-volatile memory does the STM32L071VZT7 provide, and why is the integrated EEPROM significant for data-logging designs?
The STM32L071VZT7 integrates 192 KB of Flash program memory, 20 KB of SRAM, and 6 KB of true EEPROM. The 6 KB EEPROM allows up to 100,000 write-erase cycles for storing configuration parameters, calibration coefficients, and sensor logs without requiring an external I2C EEPROM chip, reducing BOM cost and PCB complexity in smart meter, environmental monitor, and industrial sensor designs.
Which communication interfaces are available on the STM32L071VZT7 in its 100-pin LQFP package?
In the 100-pin LQFP100 package, the STM32L071VZT7 provides up to 3 USARTs, 3 SPIs, 3 I2C buses, USB 2.0 full-speed (12 Mbps), and LPUART for low-power serial communication. These interfaces support concurrent connection to wireless modules (UART), external sensors (I2C/SPI), and USB host/device communication, covering the majority of IoT node connectivity requirements at a supply voltage of 1.65 V to 3.6 V.
When should a designer choose the STM32L071VZT7 over the smaller STM32L071CBT6 in a new IoT product?
A designer selects the STM32L071VZT7 (100-pin LQFP100) over the STM32L071CBT6 (48-pin LQFP48) when the application requires more than 36 GPIO pins or multiple simultaneous peripherals such as USB plus 2 SPI buses plus 2 I2C buses. The VZT7 variant provides up to 87 GPIOs versus the CBT6's 38, and its larger 100-pin package supports complex human-machine interfaces, multi-sensor fusion nodes, or building automation controllers needing dense I/O connectivity at 3.3 V.
