Overview

The USART (Universal Synchronous Asynchronous Receiver Transmitter) offers a flexible means of full-duplex data exchange with external equipment requiring an industry standard NRZ asynchronous serial data format. It also offers more accuracy of baud rates using a fractional baud rate generator. The USART supports both synchronous one-way and Half-duplex Single-wire communications, as well as Smartcard protocol and modem operations (CTS/RTS) are also supported. High speed data communication is possible by using the DMA Channel with DMA Controller.

Key features

  • Full duplex, asynchronous communications
  • Two internal FIFOs for transmit and receive data:
    • The width of FIFOs is <9> bit,
    • The depth of FIFOs is <16>
  • A common programmable transmit and receive baud rate
    • intergral baud rate generator systems,
    • fractional baud rate generator systems
  • Auto baud rate detection
  • Programmable data word length (5/6/7/8/9 bits)
  • Configurable stop bits (0.5/1/1.5/2 stop bits) in TX and RX
  • Parity control:
    • Transmits parity bit,
    • Checks parity of received data byte
  • Single wire half duplex communication
  • Synchronous master/slave mode and clock output/input for synchronous communications
  • Support DMA access with DMA controller for high speed data communication
  • Separate enable bits for Transmitter and Receiver:
    • The TX and RX can worked in DMA or CPU mode separately
  • Support Hardware flow control for modem
  • Programmable data order with MSB-first or LSB-first shifting
  • Separate signal polarity control for transmission and reception
  • Swappable Tx/Rx pin configuration
  • Support RS-485 transceiver
  • Smartcard mode:

Capturing a UART Design in MyHDL & Testing It in an FPGA

The universal asynchronous receiver/transmitter (UART) is an old friend to embedded systems engineers. It's probably the first communications protocol that we learn in college. In this article, we will design our very own UART using MyHDL.

Integrating Post-Quantum Cryptography (PQC) on Arty-Z7

Post-quantum cryptography (PQC) is moving from theory to engineering reality. With NIST-standardized algorithms ML-KEM (FIPS 203) and ML-DSA (FIPS 204) now finalized, FPGA developers face a practical challenge: How to integrate these algorithms efficiently on resource-constrained hardware?

How to design secure SoCs, Part V: Data Protection and Encryption

In today’s connected world, where data is a crucial asset in SoCs, Part V of our series explores how to protect and encrypt data, whether at rest, in transit, or in use building on our earlier blog posts of the series: Essential security features for digital designers, key management, secure boot, and runtime integrity.

Not all overvoltage tolerant GPIOs are the same

Most foundries provide GPIO libraries to their fabless customers. These libraries contain different elements like supply/ground pads, analog I/Os, digital I/Os, corner cells, filler cells, power-on-reset circuits. Frequently the foundry includes cells for different voltage domains. In 40nm CMOS the IC designer can use cells for 1.8V, 2.5V and 3.3V for instance.
