SC16C554DBIA68-T Overview
The PLCC package is the most cost-effective.Transmission uses 4 channels.UART is important that the operating temperature does not exceed -40°C in order for the machine to perform normally for a long time.It is important to keep the operating temperature below 85°C to ensure a long working period.When the supply voltage is kept below 5.5V, reliability can be assured.Keeping the supply voltage above 2.25V ensures reliability.5V is the supply voltage provided for high-efficiency operation.
