²ÝÁñÉçÇø

Key Benefits:

• SW re-programmable, feature rich ²ÝÁñÉçÇø UART
• Low-level device driver included
• Industry standard interfaces (AMBA? APB)
• Area efficient solution
• All available configurations in a single bundle

The UART supports the following functions:

• Conforms to AMBA APB interface specification
• Request/ response data flow DMA controller interface
• Two independent clock domains for APB bus and UART logic
• Auto-baud functionality for automatically detecting and setting the baud-rate
• Break character transmission and reception
• (Automatic) Hardware CTS/ RTS flow control
• Full modem interface control signals (CTS, RTS, DSR, DTR, RI, DCD)
• IrDA encoder/ decoder
• 16-bit integer divider and fractional divider to support non-standard baud-rates
• Non-standard baud rates at low clock frequencies using variable over sampling
• Asynchronous wake-up interrupt when system clock is shut down
• Standard asynchronous error and framing bits (start, stop, parity, overrun and break)
• 5, 6, 7, or 8-bit characters
• Even, odd, no-parity
• 1, 1.5, or 2 stop bits
• Multiprocessor/ Multidrop communication
• Extensive transmit, receive, line-status and data set interrupts independently controlled
• Programmable FIFO trigger levels
• Loop-back controls for communication link fault isolation

Example Applications:

• RS-232: Standard for point-to-point serial binary data communication, mostly used for computer serial ports
• RS-422/ RS-423/ RS-485: Widely used as an interface for telecommunications, industrial, medical, security and networking applications. RS-422/ RS-423/ RS-485 are extended with multi-drop(RS-422/ RS-423) or multi-point (RS-485) communication to allow multi
• LIN: The Local Interconnect Network (LIN) is a networking protocol commonly used for automotive network architectures.
• IrDA: Infrared Data Association, a standard used for communication between devices
• Bluetooth: Open standard for wireless communication over small distances over a Ultra High Frequency band
• GPS: Global Positioning System, providing reliable positioning navigation and timing services to worldwide users on a continuous basis
