46 / 84 page ![]() Electrical parameters STM8TL52x4 STM8TL53x4 46/84 DocID022344 Rev 7 9.3.2 Power supply Figure 10. Power supply scheme 1. Each power supply pair must be decoupled with filtering ceramic capacitors as shown above. These capacitors must be placed as close as possible to, or below, the appropriate pins to ensure the correct functionality of the device. 2. The 1µF capacitor must be connected to the VDD pin. 3. The 1µF ceramic capacitor connected to PXS_VREG must be low ESR ( ). 9.3.3 Power-up / power-down operating conditions ESR 1 Table 17. Operating conditions at power-up / power-down Symbol Parameter Conditions Min. Typ. Max.
