The TL16C554A from Texas Instruments is an enhanced quadruple asynchronous communications element (ACE). It consists of four improved TL16C550C ACEs with steering logic. In FIFO mode, each transmitter and receiver is buffered with a 16-byte FIFO, reducing CPU interrupts. The device supports operation at clock rates up to 16 MHz, enabling up to 1-Mbaud serial communication.
This UART offers fully programmable serial interface characteristics, including 5- to 8-bit characters, even/odd/no parity, and 1, 1.5, or 2 stop bits. It features programmable baud-rate generators and supports both 3.3V and 5V power supplies. The TL16C554A includes independent transmit, receive, line status, and data set interrupts, along with modem control functions like CTS, RTS, DSR, DTR, RI, and DCD.
Available in PLCC and LQFP packages, the TL16C554A is designed for surface mount applications. It provides false start bit detection, line break generation and detection, and internal diagnostic capabilities for fault isolation. Its 3-state outputs offer TTL drive capabilities for bidirectional data and control buses.
The TL16C554A supports a clock rate of up to 16 MHz.
The TL16C554A supports baud rates up to 1 Mbit/s.
The TL16C554A operates at 3.3V or 5V.
