Quard Uart with 256-Byte FIFO
1. Functional Description
IN16C1054 is a quad UART(Universal Asynchronous Receiver/Transmitter) with 256-byte FIFO supporting maximum
communication speed of 5.3Mbps. It offers flow control function by hardware or software and signal lines which can open
or close the Tx/Rx input/output when communicating by RS-422 or RS-485. It can handle four interrupt signals (INT0,
INT1, INT2 and INT3) with one global interrupt signal line (GINT) and offers a new ‘Xoff re-transmit’ function in addition to
Xon any character.
UART can convert 8-bit parallel data to asynchronous serial data and vice versa. It can transmit 5 to 8-bit letters, program
I/O interrupt trigger level and has 256-byte I/O data FIFO.
www.DaUtAaRShTeceat4nUg.ceonmerate any baud rate using clock and programmable divisor, transmit data with even, odd or no parity and 1,
1.5, 2 stop bit, and detect break, idle, framing error, FIFO overflow and parity error in input data.
UART has a software interface for modem controlling.
IN16C1054 offers TQFP80 and PLCC68 packages.
