Universal Asynchronous Receiver Transmitter

Overview

The iniUART is an innovative, flexible implementa-tion of an Universal Asynchronous Receiver Trans-mitter (UART) device. iniUART, which uses the RS-232 serial protocol, provides the interface between a microprocessor and a serial port or between the system and a standard serial port. The core contains a highly accurate programmable baud rate generator, serial receiver and transmitter communications channels, and interrupt control signals.

Key Features

Configurable transfer rate: 1200bps - 115.2kbps with accuracy better than 0.15% from 8Mhz clock!
Data format: 7, 8 bits
Parity enable, odd/even, parity error detection
Stopbit: 1 or 2 bits
Format check, glitch rejection
3 point input sampling
Parallel interface with event control
Customizable data format and protocols for non standard applications

Benefits

The iniUART core may be used as a data link layer
with parallel interfaces and event communication.
Application-specific blocks (e.g., interrupt controller, special interfaces, status reporting circuits) can then be built around the iniUART and will not affect the main functionality.
Structured, synchronous VHDL Design
