SC28L194A1A - Brand New PHI UARTs (Universal Asynchronous Receiver Transmitter)
-
DESCRIPTION
The Philips 28L194 Quad UART is a single chip CMOS-LSI communications device that provides 4 full-duplex asynchronous channels with significantly deeper 16 byte FIFOs, Automatic in-band flow control using Xon/Xoff characters defined by the user and address recognition in the Wake-up mode. Synchronous bus interface is used for all communication between host and QUART. It is fabricated in Philips state of the art CMOS technology that combines the benefits of low cost, high density and low power consumption.
FEATURES
• Single 3.3V and 5.0V power supply
• Four Philips industry standard full duplex UART channels
• Sixteen byte receiver FIFOs for each UART
• Sixteen byte transmit FIFOs for each UART
• In band flow control using programmable Xon/Xoff characters
• Flow control using CTSN RTSN hardware handshaking
• Automatic address detection in multi-drop mode
• Three byte general purpose character recognition
• Fast data bus, 15 ns data bus release time, 125 ns bus cycle time
• Programmable interrupt priorities
• Automatic identification of highest priority interrupt pending
• Global interrupt and control registers ease setup and interrupt handling
• Vectored interrupts with programmable interrupt vector formats
– Interrupt vector modified with channel number
