COM81C17 General Description
The COM81C17 TPUART is an asynchronous only receiver/transmitter with a built in programmable baud rate generator housed in a twenty pin package. The TPUART receives serial data streams and converts them into parallel data characters for the processor. While receiving serial data, the TPUART will also accept data characters from the processor in parallel format and convert them into serial format along with start, stop and optional parity bus. The TPUART will signal the processor via interrupt when it has completely transmitted or received a character and requires service. Complete status information is available to the processor through the status register. The TPUART features two general purpose control pins that can be individually programmed to perform as terminal or modem control handshake signals.
COM81C17 Maximum Ratings

*Stresses above those listed above could cause permanent damage to the device. This is a stress rating only and functional operation of the device at any other condition above those indicated in the operation sections of this specification is not implied.
Note: When powering this device from laboratory or system power supplies, it is important that the Absolute Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp circuit be used.
