STM8L162M8T6 - 8-Bit Ultra-Low-Power MCU, 64KB Flash | STMicroelectronics
MPN: STM8L162M8T6 ✓ Hoạt độngSTM8L162M8T6 Tóm tắt
An 8-bit microcontroller (MCU) is a single-chip computer with an 8-bit data bus, executing instructions sequentially. It integrates a processor core, memory (Flash, RAM), and peripherals (timers, UART, SPI, I2C, ADC) on one IC. In the hierarchy of embedded systems, an MCU is a type of integrated circuit, specifically a microcontroller, which falls under the broader category of semiconductors. The STM8L EnergyLite series is optimized for ultra-low-power operation, making it a key component in battery-powered and energy-harvesting designs.
Key features include multiple low-power modes (Wait, Low-power Run, Low-power Wait, Active-halt, Halt) with current consumption as low as 0.3 µA in Halt mode, a 12-bit ADC, two comparators, a real-time clock (RTC), and a wide range of communication interfaces (USART, SPI, I2C). The device also includes an LCD driver (up to 8x40 segments), a 12-bit DAC, and a DMA controller, enhancing its versatility for sensor and display applications.
The STM8L162M8T6 is built on a low-leakage CMOS process, achieving industry-leading energy efficiency. Its architecture supports fast wake-up times (as low as 4 µs) and dynamic voltage scaling, allowing designers to balance performance and power consumption. The integrated bootloader and in-application programming (IAP) capabilities simplify firmware updates in the field.
Typical applications include portable medical devices (glucose meters, pulse oximeters), smart meters, wireless sensor nodes, and industrial process control. Its ultra-low-power modes and rich analog peripherals make it ideal for battery-powered systems where every microamp matters.
When designing with this MCU, pay attention to the power supply decoupling: place a 100 nF capacitor close to each VDD pin and a 1 µF capacitor at the main supply. Use the low-power modes strategically to extend battery life, and ensure the crystal oscillator layout is clean to maintain accurate timing.

Ghi chú thiết kế
Decouple each VDD pin with a 100 nF ceramic capacitor placed as close as possible to the pin. Additionally, place a 1 µF capacitor at the main power input. For analog circuits, use a separate VDDA/VSSA supply with a ferrite bead and 10 µF 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 kΩ 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.
