Technical Description

Each serial port utilizes a 16C950 UART featuring programmable baud rates, data format, interrupt control
and industry-leading 128-byte transmit and receive FIFOs. This high-performance UART includes 9-bit
framing support and is fully software compatible with legacy 16550 applications. In addition, the 14.7456
oscillator and UART’s flexible clock prescaler supports the widest range of standard and non-standard baud
rates to 921.6K bps. Refer to Appendix C for cable length limitations.

Connector Pin Assignments

Board Connector (DB25 Male)

The 7202e board includes a DB25 male connector for attaching the included cable (Item# CA203). The pin
