• Manufacturer: IK Semicon Co., Ltd

1. Description
2. Features
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.
