Overview

The 1.2V Thin Gate GPIO is an IP macro for on-chip integration. It is a 1.2V general purpose I/O that does not rely on thick-gate devices. Only thin-gate, 0.9V capable core MOS devices are used in the design.

Supported features include core isolation, programmable slew rate compensation, programmable drive strength, input/output enable, pull select and pull enable. Extra features such as programmable hysteresis can be supported upon request.

The 1.2V Thin Gate GPIO targets radiation hard applications or other applications prohibiting the use of thick gate I/O devices. By default, a 2kV HBM ESD protection is included. This is however easily scaled to any desired level. This specific IP macro is designed in TSMC 28nm RF HPC+, and can be ported to other technologies upon request using Sofics inhouse design tool flow.

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?

From I2C to I3C: Evolution of Two-Wire Communication in Embedded Systems

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a simple two-wire interface for synchronous, multi-master/multi-slave, single ended serial communication. Fast forward 45 years to today and it is still widely used for attaching low speed peripheral Integrated Circuits (ICs), processors and microcontrollers. But silicon today has changed...
