1. Description
IN16C1058
OCTAL UART WITH 256-BYTE FIFO
JUNE 2009 REV 1.0
IN16C1058 is a octal 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 eight internal
interrupt signals (INT0, INT1, INT2, INT3, INT4, INT5, INT6 and INT7) with one global
interrupt signal line (INT) 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.
UART can generate 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.
IN16C1058 offers TQFP128 (20x20 body) packages.

Description
70 I Clear to Send (active low). These pins indicate the modem is ready to
82 I accept transmitted data from the UART, and affect transmit and receive
92 I operations only when Auto-CTS function is enabled.

69 O Data Terminal Ready (active low). These pins indicate UART is ready to
81 O transmit or receive data.

71 I Data Set Ready (active low). These pins indicate modem is powered-on
81 I and is ready for data exchange with UART.

76 I Carrier Detect (active low). These pins indicate that a carrier has been
86 I detected by modem.

112 I
124 I
6I
18 I
28 I
77 I Ring Indicator (active low). These pins indicate the modem has received a
87 I ringing signal from telephone line. A low to high transition on these input
103 I pins generates a modem status interrupt, if enabled.
