- Lower standby current (vs LPC812M101JDH20)
Design Notes
Ensure proper decoupling of the VDD pins with 100nF capacitors placed as close to the pins as possible. Additionally, add a 4.7Β΅F bulk capacitor on the main power rail. For battery-powered designs, utilize the low-power modes (Sleep, Stop, Standby) to minimize current consumption. The standby current is only 0.3 Β΅A, but ensure all GPIOs are configured correctly to avoid leakage currents.
For the TSSOP-20 package, ensure the PCB footprint matches the recommended land pattern from the datasheet. Use a 0.65mm pitch with appropriate pad sizes. Place the crystal oscillator (if used) close to the OSC pins and keep traces short to minimize parasitic capacitance. For the SWD debug interface, route the SWDIO and SWCLK signals with controlled impedance if possible.
Do not exceed the absolute maximum ratings, especially the supply voltage of 3.6V. When using the internal HSI oscillator, calibrate it to achieve Β±1% accuracy if precise timing is required. For applications using the ADC, ensure the reference voltage is stable and bypassed with a capacitor. Also, be aware that the STM32G041F8P6 does not have a dedicated VREF pin; the ADC reference is tied to VDD.
