Overview
The D26C92 is a Dual UART Core software compatible with the SC26C92, SCC2692 and SCN2681 with added features and deeper FIFOs.
It contains: 8 character receiver, 8 character transmit FIFOs, watch dog timer for each receiver, mode register 0, extended baud rate, programmable receiver and transmitter interrupts.
The D26C92 Dual Universal Asynchronous Receiver/Transmitter (DUART) is a communication device that provides two full-duplex asynchronous receiver/transmitter channels in a single package. It interfaces directly with microprocessors and may be used in a polled or interrupt driven system, furthermore provides modem and DMA interface. The operating mode and data format of each channel can be programmed independently. Additionally, each receiver and transmitter can select its operating speed as one of 27 fixed baud rates, a 16X clock derived from a programmable counter/timer, or an external 1X or 16X clock. The baud rate generator and counter/timer can operate directly from a crystal or from external clock inputs. The ability to independently program the operating speed of the receiver and transmitter make the UART particularly attractive for dual-speed channel applications such as clustered terminal systems.

This article focuses on the most important details of the modern SPI interfaces, which are improved by many useful features. But to start, let us discover the history of the modern SPI interface, because even the old, most basic SPI interfaces are still in use.
D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
With the increasing number of high-profile data and privacy breaches in the Internet of Things (IoT) systems, businesses and consumers have a greater awareness of the need for security when buying connected products.
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.
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?
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.
