Typical Applications
STM8L162M8T6 is suitable for 6 applications: Portable Medical Devices, Smart Meters, Wireless Sensor Nodes, Industrial Process Control, Consumer Electronics, Automotive Body Electronics.
Portable Medical Devices
The STM8L162M8T6 is ideal for portable medical devices like glucose meters and pulse oximeters due to its ultra-low-power modes (0.3 Β΅A Halt) and 12-bit ADC for precise sensor readings. Its 1.8V minimum supply allows operation from a single Li-ion cell, and the integrated LCD driver can display results directly. The 16 MHz core provides enough processing power for real-time signal processing, while the low-power modes extend battery life between charges. Designers can use the RTC for time-stamping measurements and the USART for data logging to an external memory.
Recommended
Smart Meters
In smart meters, the STM8L162M8T6 excels with its integrated LCD driver (8x40 segments) for displaying consumption data, and its 12-bit ADC for accurate current/voltage sensing. The ultra-low-power modes enable battery-backed operation for decades, while the USART supports communication with PLC or RF modules. The DMA controller offloads data transfer, reducing CPU load. The wide operating voltage (1.8V-3.6V) accommodates various power supply designs, and the robust STM8 core ensures reliable operation in harsh grid environments.
Recommended
Wireless Sensor Nodes
The STM8L162M8T6 is perfect for wireless sensor nodes in IoT applications. Its 0.3 Β΅A Halt mode and fast wake-up (4 Β΅s) allow duty-cycled operation, maximizing battery life. The 12-bit ADC and comparators interface with various sensors, while the SPI/I2C/USART connect to wireless modules like LoRa or Zigbee. The 64KB Flash provides ample space for communication protocols and data buffering. The small 80-LQFP package fits compact node designs, and the wide voltage range supports energy harvesting sources.
Recommended
Industrial Process Control
For industrial process control, the STM8L162M8T6 offers robust performance with its 16 MHz core and rich analog peripherals. The 12-bit ADC and DAC enable precise control loops, while the USART supports Modbus communication. The extended temperature range (-40Β°C to +85Β°C) ensures reliability in factory environments. The multiple timers and PWM outputs can drive actuators, and the low-power modes reduce energy consumption during idle periods. The 68 I/O pins provide ample connectivity for sensors, switches, and indicators.
Recommended
Consumer Electronics
In consumer electronics like remote controls, wearables, and smart home devices, the STM8L162M8T6 provides a cost-effective, low-power solution. Its integrated LCD driver can display time or status, and the 12-bit ADC reads battery voltage or touch sensors. The ultra-low-power modes allow devices to run for years on a coin cell. The 16 MHz core handles user interface logic and communication protocols like IR or Bluetooth (via external module). The small package and wide voltage range simplify PCB design.
Recommended
Automotive Body Electronics
The STM8L162M8T6 is suitable for automotive body electronics like window lifters, seat control, and lighting modules. Its wide operating voltage (1.8V-3.6V) and robust I/O handle automotive supply variations. The LIN interface (via USART) enables communication with the vehicle network. The 12-bit ADC monitors switch positions and sensor inputs, while the PWM outputs drive motors or LEDs. The extended temperature variant (STM8L162M8T7) is recommended for under-hood applications. The low-power modes reduce battery drain when the vehicle is off.

Key Differentiators
- Integrated LCD driver (8x40 segments) (vs STM8L151M8T6)
- 12-bit DAC and DMA controller (vs STM8L152M8T6)
- Ultra-low-power Halt mode (0.3 Β΅A) (vs PIC18F67K40)
Design Notes
Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the pin. Additionally, place a 1 Β΅F capacitor at the main power input. For analog circuits, use a separate VDDA/VSSA supply with a ferrite bead and 10 Β΅F capacitor to reduce noise. The wide operating voltage (1.8V-3.6V) allows direct battery connection, but ensure the supply is stable during peak current draws.
For the 80-pin LQFP package, use a 4-layer PCB with a solid ground plane. Route the crystal oscillator (OSC_IN/OSC_OUT) with short traces and a ground guard ring to minimize parasitic capacitance. Keep high-speed communication lines (SPI, I2C) away from the crystal and analog pins. Use via stitching around the ground pad to improve thermal performance.
Ensure the NRST pin is pulled high with a 10 kΞ© resistor and a 100 nF capacitor to ground to prevent spurious resets. When using the ADC, set the sampling time appropriately for the source impedance. Do not leave unused I/O pins floating; configure them as outputs or enable internal pull-ups. For low-power operation, disable unused peripherals and use the Halt mode with wake-up sources like the RTC or external interrupts.
Compliance Information
RoHS compliant per STMicroelectronics product page. Not AEC-Q100 qualified; use STM8L162M8T7 for automotive applications requiring extended temperature.
