Vendor: eSi-RISC Category: UART

APB UART with optional ISO7816-3

The eSi-UART core can be used to implement asynchronous serial communications.

Overview

The eSi-UART core can be used to implement asynchronous serial communications. It is ideally suited for implementing RS232 or ISO7816-3 for smartcard based connectivity. The UART is supplied with an AMBA APB slave interface and so can be driven by software or via DMA.

Key features

  • 7 or 8 data bits.
  • 1 or 2 stop bits.
  • Parity bit (None / Even / Odd / Mark / Space).
  • Optional RTS/CTS flow control.
  • Programmable bit rate.
  • Optional ISO 7816-3 T=0 and T=1 support, with NACK and retry.
  • Configurable TX and RX FIFO.
  • Programmable receive timeout and transmit guard time.
  • AMBA 3 APB slave interface.
  • DMA flow-control interface.

eSi-RISC
HQ: UK
eSi-RISC designs and licenses the eSi-RISC range of configurable, low-power, RISC CPU IP cores, as well as associated peripheral IP cores and software development tools. The eSi-RISC processors are unique in being configurable from a base 16-bit core (eSi-1600) to a 32-bit, multi-core CPU with optional caches (eSi-3250), to a high-performance DSP core with 64-bit fixed-point SIMD and floating point support (eSi-3264). As well as supplying individual cores, eSi-RISC can develop complete SoC sub-systems combining CPUs, memory and peripherals (DMA, memory-controllers, I2C, UART, SPI, etc.), using an AMBA AXI/AHB/APB based interconnect, generated automatically using our eSi-SoC EDA tool.

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.
