  • Ultra-low power consumption with 0.3 µA Halt mode (vs STM8L051F3P6)

  • Same package and pinout as STM8L101F3P6TR (vs STM8L101F3P6TR)

設計ノート

The STM8L101F3P6 operates from 1.8V to 3.6V. Use a low-dropout regulator (LDO) to provide a stable supply voltage if the input source varies. Place a 100nF decoupling capacitor close to the VDD pin and a 1µF capacitor on the VDD rail to filter high-frequency noise. In battery-powered designs, leverage the Halt and Active-halt modes to minimize current consumption; ensure the device is properly configured to wake up from these modes via interrupts or reset.

For the 20-pin TSSOP package, ensure adequate copper pour for the ground plane to reduce noise and improve thermal performance. Keep the crystal oscillator (if used) close to the MCU and route the clock traces with controlled impedance. Use short, wide traces for power and ground connections. Place the decoupling capacitors as close as possible to the VDD and VSS pins to minimize parasitic inductance. Follow ST's layout guidelines for the STM8L family to ensure reliable operation.

A common pitfall is forgetting to configure the unused I/O pins to a defined state (e.g., input with pull-up or output low) to avoid floating inputs and excessive current consumption. Also, ensure the NRST pin is properly pulled up with a 100nF capacitor to ground to prevent spurious resets. When using the USART, SPI, or I2C interfaces, verify the alternate function mapping in the datasheet to avoid pin conflicts. Finally, do not exceed the absolute maximum ratings for supply voltage and I/O pins to prevent damage.
