The UARTmodule is part of Inicore's IPmodule family. Universal asynchronous receiver and transmitter, using the RS232 protocol, are often used to connect peripheral devices to a central controller.
The UARTmodule has one receive and one transmit channel, receive and transmit buffers, an interrupt controller as well as a local bus interface. The built-in receive buffer is configurable in depth, therefore, enabling a gate count and application optimized implementation.
The baudrate generator uses a innovative digital controlled oscillator (DCO) to generate baudrates over a wide frequency range. With a system clock of 8MHz, all baudrates from 1200 baud to 115.2 kbaud have an accuracy of better than 0.1%!
To improve glitch rejection, the receiver uses a 3-point input sampling. Format and parity errors are detected and reported.
Implementation Features
- Supports register and SRAM based FIFO implementations.
- The Rx-FIFO size is selectable enabling the optimal device utilization
- Fully synchronous design: one clock, one global asynchronous reset.
- Technology independent implementation. This design can be used for any technology as long as timing constraints are met.
