STM8L152R8T6 概要
An 8-bit microcontroller is a single-chip computer with an 8-bit data bus, typically used in embedded systems where cost, power efficiency, and simplicity are prioritized over raw processing power. The STM8L152R8T6 belongs to the STM8L series, which is specifically designed for ultra-low-power operation, featuring multiple low-power modes (Wait, Low-power Run, Low-power Wait, Active-halt, and Halt) to minimize energy consumption. In the broader hierarchy, it sits as a microcontroller -> 8-bit MCU -> ultra-low-power MCU -> STM8L EnergyLite family, and is a key component in battery-powered and energy-harvesting applications.
Key features include an ultra-low-power STM8 core with up to 16 MHz operation, 64 KB Flash with read-while-write capability, 4 KB RAM, 2 KB true data EEPROM with error correction code (ECC), and a 12-bit ADC with up to 28 channels. The device also integrates a 12-bit DAC, two comparators, an LCD driver supporting up to 8x40 segments, and a real-time clock with calendar and alarm functions. Its low-power design achieves typical current consumption of 3.4 µA in Halt mode with RTC on, and 0.35 µA in Halt mode without RTC, making it ideal for battery-powered devices.
From a technical depth perspective, the STM8L152R8T6 uses a Harvard architecture with a 3-stage pipeline, allowing most instructions to execute in a single clock cycle. The Flash memory supports read-while-write, enabling firmware updates without halting the CPU. The device includes a flexible clock system with internal and external oscillators, a phase-locked loop (PLL) for frequency multiplication, and a clock security system for fail-safe operation. The ultra-low-power design is achieved through advanced process technology and multiple power domains, allowing independent power management of the core, peripherals, and I/O.
Typical applications include portable medical devices (e.g., glucose meters, pulse oximeters), smart meters, wireless sensor nodes, and industrial control systems. The STM8L152R8T6's low power consumption and rich analog peripherals make it particularly well-suited for battery-powered applications where long battery life is critical. Its LCD driver and RTC also make it ideal for consumer electronics like digital thermometers and smart watches.
When designing with this device, pay careful attention to the power supply decoupling: place a 100 nF capacitor close to each VDD pin and a 1 µF capacitor at the main power input. Additionally, configure the unused I/O pins to analog mode or low-power mode to minimize leakage current, and use the low-power modes effectively to extend battery life.

主な用途
STM8L152R8T6 の用途: 6 件s: Portable Medical Devices, Smart Meters, Wireless Sensor Nodes, Industrial Control Systems, Consumer Electronics with LCD, Test and Measurement Instruments.
Portable Medical Devices
The STM8L152R8T6 is ideal for portable medical devices such as glucose meters, pulse oximeters, and blood pressure monitors. Its ultra-low-power consumption (0.35 µA in Halt mode) extends battery life, while the integrated 12-bit ADC and comparators enable precise sensor measurements. The LCD driver supports small displays for patient data, and the wide supply voltage range (1.8V to 3.6V) allows operation from two AA batteries. In a typical glucose meter, the MCU reads the sensor via the ADC, processes the data, and displays results on the LCD, all while maintaining low power consumption to ensure months of operation on a single battery set.
おすすめ
Smart Meters
The STM8L152R8T6 is well-suited for smart meters (electricity, water, gas) due to its low power consumption and rich peripheral set. The 12-bit ADC can measure voltage and current from sensors, while the RTC provides accurate time-stamping for usage data. The LCD driver displays consumption information, and the USART/I2C interfaces enable communication with external modems or PLC transceivers. In a smart electricity meter, the MCU samples the mains voltage and current, calculates energy consumption, and periodically transmits data via a communication module, all while operating from a battery or energy harvesting source. Its low-power modes ensure minimal energy draw during idle periods.
おすすめ
Wireless Sensor Nodes
The STM8L152R8T6 is an excellent choice for wireless sensor nodes in IoT applications. Its ultra-low-power modes (0.35 µA in Halt) allow long battery life, and the integrated ADC and comparators interface with various sensors (temperature, humidity, pressure). The SPI/I2C interfaces connect to RF transceivers like the SX1276 for LoRa communication. In a typical node, the MCU wakes periodically, reads sensors, processes data, and transmits via the RF module, then returns to sleep. The wide supply voltage range and low-power operation make it suitable for battery-powered or energy-harvesting deployments in industrial and agricultural monitoring.
おすすめ
Industrial Control Systems
The STM8L152R8T6 can be used in industrial control systems for monitoring and control tasks. Its 16 MHz core provides sufficient processing power for real-time control loops, while the timers and PWM outputs drive actuators and motors. The USART and I2C interfaces enable communication with PLCs, sensors, and displays. The device's wide operating temperature range (-40°C to 125°C) ensures reliability in harsh environments. In a typical industrial controller, the MCU reads analog sensors via the ADC, executes control algorithms, and outputs PWM signals to adjust motor speed or valve position. Its low-power modes are useful for battery-backed systems or energy-saving applications.
おすすめ
Consumer Electronics with LCD
The STM8L152R8T6 is perfect for consumer electronics that require an LCD display, such as digital thermometers, smart watches, and kitchen appliances. The integrated LCD driver supports up to 8x40 segments, eliminating the need for an external display driver. The low-power modes extend battery life in portable devices. In a digital thermometer, the MCU reads the temperature sensor, processes the data, and displays it on the LCD, all while consuming minimal power. The RTC can also be used for time-stamping and alarms. The device's small footprint (64-LQFP) fits compact designs.
おすすめ
Test and Measurement Instruments
The STM8L152R8T6 is suitable for portable test and measurement instruments like multimeters, data loggers, and signal generators. Its 12-bit ADC and DAC provide accurate analog measurement and generation, while the timers enable precise frequency and pulse generation. The USART interface allows data logging to a PC or external memory. In a portable multimeter, the MCU measures voltage, current, and resistance via the ADC, displays readings on the LCD, and can store measurements in the data EEPROM. The low-power modes are essential for battery-operated instruments, ensuring long field operation.

設計ノート
The STM8L152R8T6 operates from 1.8V to 3.6V. Use a low-dropout regulator (LDO) to provide a stable supply if the input voltage varies. Place a 100 nF ceramic capacitor close to each VDD pin and a 1 µF capacitor at the main power input. For battery-powered designs, consider using the low-power modes to reduce current consumption to as low as 0.35 µA in Halt mode.
For the 64-pin LQFP package, ensure proper soldering with a 0.5 mm pitch. Use a 4-layer PCB with a solid ground plane to minimize noise. Place decoupling capacitors as close as possible to the power pins. For the LCD driver, route the segment and common lines carefully to avoid crosstalk, especially in high-impedance modes.
Unused I/O pins should be configured to analog mode or low-power mode to minimize leakage current. Ensure the NRST pin is properly pulled up with a 100 nF capacitor to ground to avoid spurious resets. When using the RTC, ensure the correct clock source is selected (LSI or LSE) to maintain accurate timekeeping. Also, verify that the supply voltage does not exceed the absolute maximum rating of 4.0V.
