SC28L92A1A A - Brand New PHILIPS UARTs (Universal Asynchronous Receiver Transmitter)
-
DESCRIPTION
The SC28L92 is a pin and function replacement for the SCC2692 and SC26C92 operating at 3.3 or 5 volts supply with added features and deeper FIFOs. Its configuration on power up is that of the SC26C92. Its differences from the 2692 are: 16 character receiver, 16 character transmit FIFOs, watch dog timer for each receiver, mode register 0 is added, extended baud rate and overall faster speeds, programmable receiver and transmitter interrupts. (Neither the SC26C92 nor the SCC2692 is being discontinued.)
FEATURES
• Member of IMPACT family: 3.3 to 5.0 volt , –40°C to +85°C and 68K for 80xxx bus interface for all devices.
• Dual full-duplex independent asynchronous receiver/transmitters
• 16 character FIFOs for each receiver and transmitter
• Pin programming selects 68K or 80xxx bus interface
• Programmable data format
– 5 to 8 data bits plus parity
– Odd, even, no parity or force parity
– - 1, 1.5 or 2 stop bits programmable in 1/16-bit increments
• 16-bit programmable Counter/Timer
• Programmable baud rate for each receiver and transmitter selectable from:
– 28 fixed rates: 50 to 230.4k baud
– Other baud rates to MHz at 16X
– Programmable user-defined rates derived from a programmable counter/timer
– External 1X or 16X clock
• Parity, framing, and overrun error detection
• False start bit detection
• Line break detection and generation
• Programmable channel mode
– Normal (full-duplex)
– Automatic echo
– Local loop back
– Remote loop back
– Multi-drop mode (also called ‘wake-up’ or ‘9-bit’)
• Multi-function 7-bit input port (includes IACKN)
– Can serve as clock or control inputs
– Change of state detection on four inputs
– Inputs have typically >100k pull-up resistors
– Change of state detectors for modem control
• Multi-function 8-bit output port
– Individual bit set/reset capability
– Outputs can be programmed to be status/interrupt signals
– FIFO status for DMA interface
• Versatile interrupt system
– Single interrupt output with eight maskable interrupting conditions
– Output port can be configured to provide a total of up to six separate interrupt outputs that may be wire ORed.
– Each FIFO can be programmed for four different interrupt levels
– Watch dog timer for each receiver
• Maximum data transfer rates: 1X – 1Mb/sec, 16X – 1Mb/sec
• Automatic wake-up mode for multi-drop applications
• Start-end break interrupt/status
• Detects break which originates in the middle of a character
• On-chip crystal oscillator
• Power down mode
• Receiver time-out mode
• Single +3.3V or +5V power supply
• Powers up to emulate SC26C92 -
