Description
This is a schematic component for a Philips/NXP SC28L91 universal asynchronous receiver/transmitter (UART) in a PLCC44 package. This UART is capable of running at standard speeds up to 230.4 kilobits per second (Kbps), 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 MAX232 to set up a high speed TIA-232 channel with CTS/RTS handshaking. Mate the UART with a MAX238 to set up a full modem interface.
Note that although the PLCC44 version of this device is currently out of production it can be purchased through a number of wholesale sources, such as USBid (http://www.usbid.com).
