Description
The SC26C92A1B is a UART (Universal Asynchronous Receiver Transmitter) electronic component model. It is a pin and function replacement for the SCC2692 and SCN2681 with added features and deeper FIFOs. Its configuration on power up is that of the 2692. Its differences from the 2692 are: 8 character receiver, 8 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. (The SCC2692 is not being discontinued.)
Specifications and features
- Dual full-duplex independent asynchronous receiver/transmitters
- 8 character FIFOs for each receiver and transmitter
- 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:
- 27 fixed rates: 50 to 230.4k baud
- Other baud rates to 230.4k baud 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 loopback
- Remote loopback
- Multidrop mode (also called 'wake-up' or '9-bit')
- Multi-function 7-bit input port:
- Can serve as clock, modem, or control inputs
- Change of state detection on four inputs
- Inputs have typically >100k pull-up resistors
- Multi-function 8-bit output port:
- Individual bit set/reset capability
- Outputs can be programmed to be status/interrupt signals
- FIFO states for DMA and modem 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 wire-ORable interrupt outputs
- 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 multidrop applications
- Start-end break interrupt/status
- Detects break which originates in the middle of a character
- On-chip crystal oscillator
- Power down mode
- Receiver timeout mode
- Single +5V power supply
- Powers up to emulate SCC2692
Application Scenarios
The SC26C92A1B can be used in various applications that require UART functionality. Some example scenarios include:
- Communication devices such as modems and routers
- Industrial control systems
- Embedded systems
- Internet of Things (IoT) devices
