SC16C554 - IC 4 CHANNEL(S), 5M bps, SERIAL COMM CONTROLLER, PQFP64, 10 X 10 MM, 1.40 MM HEIGHT, PLASTIC, MS-026, SOT-314-2, LQFP-64, Serial IO/Communication Controller
The maximum clock frequency for the SC16C554BIB64,157 is 16 MHz.
To configure the UART for 9-bit data transmission, set the MCR register to enable 9-bit mode, and then set the LCR register to select the 9-bit data length.
The maximum baud rate supported by the SC16C554BIB64,157 is 1.5 Mbps.
To handle FIFO interrupts, enable the FIFO interrupt in the IER register, and then use the ISR register to determine the cause of the interrupt. Clear the interrupt by reading the FIFO data or resetting the FIFO.
Yes, the SC16C554BIB64,157 is compatible with 3.3V systems. However, ensure that the input voltage (VCC) is within the recommended operating range of 2.97V to 3.63V.
