SC16C554B/554DB
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 16-byte FIFOs
A single baud rate generator is provided for the transmitter and receiver, allowing
independent TX/RX channel control. The programmable Baud Rate Generator is capable
of accepting an input clock up to 80 MHz (for 3.3 V and 5 V operation), as required for
supporting a 5 Mbit/s data rate. The SC16C554B/554DB can be configured for internal or
external clock operation. For internal clock oscillator operation, an industry standard
microprocessor crystal (parallel resonant/22 pF to 33 pF load) is connected externally
between the XTAL1 and XTAL2 pins (see
Figure 11
). Alternatively, an external clock can
be connected to the XTAL1 pin to clock the internal baud rate generator for standard or
custom rates (see
Table 8
).
Programming the Baud Rate Generator registers DLM (MSB) and DLL (LSB) provides a
user capability for selecting the desired final baud rate.
