STM32L071VZT6 - 32MHz Cortex-M0+ 192KB MCU | STMicroelectronics
MPN： STM32L071VZT6 ✓ 啟用中STM32L071VZT6 概覽
An ultra-low-power microcontroller is a semiconductor designed to minimize energy consumption during active operation, sleep, and standby states. The STM32L071 series sits within STMicroelectronics' STM32L0 product hierarchy: low-power microcontroller, 32-bit embedded MCU, Arm Cortex-M0+ processor, and general-purpose semiconductor. This positioning makes it suitable for battery-powered sensors, portable measurement equipment, industrial controllers, and connected products that must balance processing capability with energy efficiency.
The three headline attributes of the STM32L071VZT6 are its 32 MHz operating frequency, 192 KB of Flash memory, and 100-lead LQFP construction. According to the STMicroelectronics STM32L071VZ product page and distributor listings, the device uses an Arm Cortex-M0+ core operating at 32 MHz and provides 192 KB of Flash organized as 192K x 8. The listed 100-LQFP package offers a large pin count for designs that need more external connectivity than smaller 48- or 64-lead packages provide.
The STM32L0 family architecture supports efficient embedded control while retaining a conventional peripheral and GPIO-oriented design. STMicroelectronics identifies the STM32L071VZ as part of its ultra-low-power access line, indicating a balance between performance, memory, and energy-conscious operation. The Cortex-M0+ instruction set is appropriate for control loops, protocol handling, data acquisition, and supervisory tasks that do not require the compute performance of an Arm Cortex-M4 or M7 core.
Typical uses include compact environmental monitors, low-power sensor nodes, industrial sensing modules, building-access controls, wearable-adjacent accessories, and battery-operated instruments. A network interface such as the LAN8720A-CP Ethernet PHY can be paired with the MCU when wired connectivity is required, while PCA9536DR-style digital expanders can add general-purpose I/O. Firmware and software configuration determine the final application, so all peripheral availability and operating limits must be confirmed in the manufacturer datasheet before design release.
For PCB implementation, the 100-lead LQFP package requires a fine-pitch land pattern, careful decoupling near each supply pin, and adequate via-in-pad or fan-out routing beneath the device. Designers should confirm the exact pin multiplexing, debug-pad requirements, and decoupling recommendations against the STMicroelectronics datasheet rather than relying on a generic LQFP footprint library.
This page consolidates the verified distributor specifications, manufacturer product information, family-level alternatives, and practical design considerations for STM32L071VZT6 evaluation. It also distinguishes verified parameters from unresolved details so procurement and engineering teams can assess supply, footprint, and firmware implications before committing to the design.

典型應用
STM32L071VZT6 適用於 6 應用s: Industrial Environmental Sensor Nodes, Low-Power IoT Data Loggers, Connected Measurement and Control Panels, Building Access and Security Peripherals, Battery-Powered Portable Instruments, Compact Gateway and Protocol Converter.
Industrial Environmental Sensor Nodes
The STM32L071VZT6 fits battery-powered environmental monitoring when a design needs more Flash and pin access than the smaller STM32L071 packages provide. Its 32 MHz Arm Cortex-M0+ core can execute sampling, filtering, calibration, and local data-reduction algorithms, while 192 KB of Flash accommodates firmware, tables, and protocol code. The 100-lead LQFP exposes more GPIO for sensors, indicators, and local actuators. Because the verified data does not state sleep-mode current or wake-up timing, engineers should evaluate those figures from the manufacturer datasheet before setting the duty cycle and sizing the battery.
推薦
Low-Power IoT Data Loggers
The STM32L071VZT6 is suitable for IoT data loggers that periodically wake to collect information, store it locally, and transmit it through a separate radio module. The 192 KB of Flash provides room for application code, event buffers, and communication firmware, while the Cortex-M0+ core supports protocol state machines and sensor conditioning. Its 3 V operating classification aligns with many low-energy sensor and radio ecosystems. Designers should use the official low-power current tables, wake-up timing, and supply-voltage limits to calculate average energy use; those values were not present in the supplied search extracts.
推薦
Connected Measurement and Control Panels
The STM32L071VZT6 fits compact measurement panels where local controls, displays, and analog sensing must coexist with network or serial communication. Its 32 MHz Cortex-M0+ core provides enough performance for UI-state handling and acquisition tasks, and the 100-lead LQFP offers more I/O than 48- or 64-lead alternatives. The 192 KB of Flash supports firmware for multiple interfaces and configuration storage. For designs requiring Ethernet, the LAN8720A-CP can serve as a companion PHY, but its host interface requirements, reference clock, and pin multiplexing must be checked against the final STM32L071VZ package configuration.
推薦
Building Access and Security Peripherals
The STM32L071VZT6 can serve as the control device in access-control panels, credential readers, and compact security peripherals where multiple I/O points and low standby consumption are important. The 100-lead LQFP provides more interface options than smaller packages, and 192 KB of Flash is useful for protocol stacks, event logic, and secure-update code. Its 3 V classification fits many low-voltage security designs. Security-sensitive projects must still add the appropriate authentication, key storage, tamper detection, and update mechanisms; the supplied evidence confirms the MCU family but does not provide detailed security-feature certifications for this exact order code.
推薦
Battery-Powered Portable Instruments
The STM32L071VZT6 is appropriate for portable instruments that combine local display control, sensor acquisition, and intermittent communications. Its 32 MHz Cortex-M0+ processor can execute measurement control loops and user-interface state logic, while the 192 KB of Flash reduces the need for external memory. The 100-lead LQFP allows implementation in a compact handheld board with several sensors, serial ports, and control outputs. Actual battery-life performance depends on the selected STM32L0 low-power mode and peripheral activity, so designers should compare the manufacturer's sleep, stop, and standby measurements and evaluate regulator quiescent current separately.
推薦
Compact Gateway and Protocol Converter
The STM32L071VZT6 supports compact gateways or protocol converters that translate between a local sensor bus and an external communication link. The 192 KB of Flash can hold several lightweight protocol stacks and configuration tables, while the Cortex-M0+ core manages framing, checksums, and state transitions. The 100-lead package provides enough external signals for multiple serial interfaces, status LEDs, and a reset or security-control input. If an Ethernet interface is required, LAN8720A-CP is a possible companion, but the final design must confirm the STM32L071VZ peripheral allocation, PHY reference clock, and signal-level compatibility.

設計說明
Confirm the official STM32L071VZ operating-voltage range before selecting a regulator, and place the required bypass capacitors directly at the device supply pins. The verified distributor listing confirms a 3 V device but does not provide minimum, maximum, or current-consumption ratings. For battery designs, calculate average current from the duty cycles of active acquisition, sleep or stop, and standby operation, then add regulator quiescent current and external-load leakage.
Treat the 100-lead LQFP as a fine-pitch, high-pin-count land pattern with 0.5 mm pitch and a 14 x 14 mm body. Verify pin-1 orientation, courtyard, paste volume, and solder-mask clearance against the official package drawing rather than a generic LQFP library. Route sensitive analog and communication nets away from switching nodes, maintain short return paths, and provide a solid ground plane under and around the device.
Keep oscillator, debug-programming, and high-speed communication routing short, with continuous ground references and no splits beneath the MCU. Place decoupling capacitors close to their associated supply pins, with the smallest capacitors nearest the package pins to suppress high-frequency transients. Because the supplied data does not enumerate analog pins or alternate functions, use the manufacturer pin table to determine which signals require guarded traces or dedicated analog-layout treatment.
Do not treat an STM32L0 family member with the same VZ package indication as automatically firmware-identical. STM32L072VZT6, STM32L083VZT6, STM32L072V8T6, and STM32L071VZT7 require comparison of flash density, SRAM, peripherals, order-code temperature grade, pin multiplexing, and boot options. Approve a substitution only after compiling existing firmware for the candidate and verifying every peripheral and interrupt used by the product.
合規資訊
The supplied verified web data confirms the manufacturer, family, core, clock, Flash configuration, voltage, and package, but it contains no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for this exact order code. Values therefore remain unknown rather than being inferred. AEC-Q100 is marked not_applicable because this listing does not identify the target as an automotive-qualified variant.
