STM8L152C6U3 - 16MHz 32KB Ultra-Low-Power MCU | STMicroelectronics
部品番号: STM8L152C6U3 ✓ 生産中STM8L152C6U3 概要
What is an ultra-low-power microcontroller? An ultra-low-power MCU is a semiconductor controller designed to maintain useful processing, sensing and communication functions while minimizing energy consumption. The STM8L152C6U3 is positioned within the STM8L product hierarchy: STM8L152 series, STM8L EnergyLite family, 8-bit microcontroller, embedded processor and power-conscious system controller. This makes it suitable for products that spend substantial time in low-activity operating states, such as portable instruments, sensor nodes and battery-operated equipment.
The STM8L152C6U3 provides a useful combination of general-purpose peripherals and dedicated analog and display functions. Its LCD interface can reduce the need for external display-control hardware, while the ADC, DAC and comparators support measurement, signal conditioning and threshold-based control. USART, I2C and SPI interfaces allow connection to sensors, memories, displays and other digital peripherals. The 32 KB Flash capacity provides room for application firmware, while the 1 KB EEPROM supports nonvolatile parameter storage.
The 16 MHz operating speed and 2 KB RAM are appropriate for embedded control tasks that require responsive peripheral handling without a high-performance processor core. The 48-pin UFQFPN package exposes a substantial set of I/O and peripheral connections while remaining designed for surface-mount assembly. Applications include low-power sensor nodes, industrial instrumentation, medical monitoring equipment, smart meters, access-control systems and LCD-based user interfaces.
Designers should verify the exact peripheral pin assignments, clock configuration, low-power modes, operating voltage limits and exposed-pad requirements in the manufacturer datasheet. The UFQFPN thermal pad and PCB copper layout are important for reliable assembly and heat spreading. Firmware should also account for wake-up sources, RTC behavior, analog reference requirements and the distinction between run, standby and shutdown current budgets.

主な用途
STM8L152C6U3 の用途: 6 件s: Battery-Powered Sensor Nodes, Industrial Measurement Instruments, Smart Meters and Utility Displays, Medical Monitoring Equipment, Access-Control and Keypad Readers, Portable Environmental Monitors.
Battery-Powered Sensor Nodes
The STM8L152C6U3 fits battery-powered sensor nodes because its STM8L platform combines 16 MHz processing, 32 KB Flash, 2 KB RAM and low-power operation with an integrated ADC. A node can sample a sensor through the ADC, store configuration in the 1 KB EEPROM and communicate over SPI or I2C before returning to a low-power state. The RTC supports scheduled measurements and time-stamped events, while USART provides a simple diagnostic or configuration path. Battery-life calculations should use the device-specific active, standby and shutdown currents together with the sensor duty cycle.
おすすめ
Industrial Measurement Instruments
For industrial measurement instruments, the STM8L152C6U3 combines analog conversion and digital control in one 48-pin device. The 12-bit ADC can acquire process or sensor signals, the comparators can support threshold detection, and the DAC can provide a controlled analog reference or test signal. USART, I2C and SPI permit connection to transducers, memory and calibration equipment, while timers support accurate sampling and control intervals. Firmware should calibrate the analog channels and verify the operating-voltage limits required by the connected sensor network.
おすすめ
Smart Meters and Utility Displays
The STM8L152C6U3 is appropriate for smart meters and compact utility displays because it combines an LCD controller, RTC and low-power 8-bit processing in a single package. The LCD interface can display consumption, status and service information, while the RTC provides timekeeping for time-of-use records and scheduled events. USART can support an optical or communications module, and I2C or SPI can connect to metering sensors or external nonvolatile storage. Power-loss behavior, LCD contrast, metering accuracy and communication protocol handling must be validated for the final meter architecture.
おすすめ
Medical Monitoring Equipment
The STM8L152C6U3 can serve as the control MCU in compact medical monitoring equipment where low power, local display and mixed-signal control are useful. Its 16 MHz core, 32 KB Flash and 2 KB RAM are sufficient for supervisory logic, while the ADC, DAC and comparators support signal acquisition, stimulus generation and threshold checks. The LCD controller can provide local status information, and USART or I2C can connect to a sensor front end or communications module. For safety-critical functions, verify the device qualification status, isolation requirements and applicable medical-system design controls.
おすすめ
Access-Control and Keypad Readers
The STM8L152C6U3 suits access-control readers and keypad terminals because the LCD controller can drive a local display while timers and serial interfaces support credential peripherals and external readers. The 48-pin UFQFPN provides access to the relevant GPIO and communication resources, while low-power operation supports battery or selectively powered installations. USART can connect to a reader module, I2C or SPI can connect to secure storage, and the GPIO can drive indicators and controls. Firmware should include debouncing, tamper-response logic and careful backlight-power management.
おすすめ
Portable Environmental Monitors
The STM8L152C6U3 works well in portable environmental monitors that combine periodic sensing with local human-readable output. The ADC can read environmental sensors, the comparators can establish threshold events, and the RTC can schedule measurements at selected intervals. Its LCD controller reduces the need for a separate display driver, while I2C and SPI cover common sensor interfaces and USART supports configuration or logging. Low-power mode selection and sensor duty cycling are central to extending battery life, and the package's exposed pad should be connected to the PCB thermal plane according to the package guidance.

設計ノート
Use the manufacturer package drawing to define the 48-UFQFPN land pattern, including the exposed thermal pad. Place input and decoupling capacitors close to their assigned pins, keep the exposed-pad connection consistent with the recommended PCB copper arrangement, and route sensitive analog inputs away from switching nodes and high-current traces. Because pin-level details are not reproduced on this page, use the pin-description table in the datasheet for every PCB net assignment.
Design the power tree around the MCU's specified operating-voltage range and low-power current limits. Confirm the core, analog and I/O voltage domains, then ensure each external sensor and peripheral receives a rail compatible with both its requirements and the STM8L152C6U3 pin limits. Apply the datasheet's recommended decoupling network and account for analog-reference requirements when using the ADC or DAC.
Do not treat a shared 48-UFQFPN package as sufficient proof of drop-in equivalence. Compare the STM8L151 and STM8L152 peripheral tables, especially the LCD controller, and verify that every assigned pin supports the intended signal direction, voltage level and peripheral function. Also review the ordering suffix and temperature grade before production release, because package, memory size and CPU speed alone do not establish full functional compatibility.
Keep analog sensor traces short and connect them to a quiet ground reference. Place analog filtering or protection components near the MCU pins, use a continuous ground plane where practical, and avoid routing ADC inputs beneath digital clocks, LCD edges or high-speed switching nodes. For designs using SPI or other fast peripherals, follow the datasheet's GPIO speed, capacitance and signal-routing guidance.
コンプライアンス情報
The manufacturer product page identifies the STM8L152x6 family as ultra-low-power 8-bit microcontrollers, but the verified product material does not explicitly state RoHS, REACH, lead-free, halogen-free or conflict-minerals status. AEC-Q100 is not applicable to this general-purpose microcontroller ordering code unless a separate automotive-grade variant is selected.
