- 2 channel UART
- 5 V, 3.3 V and 2.5 V operation
- Industrial temperature range
- Pin and functionally compatible to 16C2450 and software compatible with SC16C650
- Up to 5 Mbits/s data rate at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V
- 32-byte transmit FIFO to reduce the bandwidth requirement of the external CPU

- Software selectable Baud Rate Generator
- Sleep mode
- Standard asynchronous error and framing bits (Start, Stop, and Parity Overrun Break)
- Transmit, Receive, Line Status, and Data Set interrupts independently controlled
- Fully programmable character formatting:
- 5-, 6-, 7-, or 8-bit characters
- Even-, Odd-, or No-Parity formats
- 1-, 1 1/2-, or 2-stop bit
