Description
This is a schematic component for a Philips/NXP SC28L92 dual-channel universal asynchronous receiver/transmitter (DUART) in a PLCC44 package. This DUART is capable of running at standard speeds up to 230.4 kilobits per second (Kbps) simultaneously on both channels, with non-standard speeds possible to 921 Kbps. It also has programmable general-purpose inputs and outputs, and a precision counter/timer that may be used for a wide variety of timing tasks, or as an alternate bit rate generator.
Mate this device to a Maxim MAX238 to set up two high speed TIA-232 channels with CTS/RTS handshaking. Mate the DUART to a MAX248 to set up a full modem interface for both channels.
