Application Notes
Power On/Off Sequence
Eastsoft MCUs are designed with separate power pins. If a MCU is applied in a system which has multiple power supplies, the MCU should be powered on first or at the same time together with other devices involved in the system. Conversely, the MCU should be powered off after all other devices are powered off. Reversed steps may cause excessive voltage or current on the MCU internal components, which is very likely to cause malfunction and weaken components performances.
