Maxim's Santa Cruz (MAXREFDES23#) reference design is the world's smallest IO-Link® light sensor compliant with IEC 61131-9. The Santa Cruz has six different types of sensors: ambient light (clear), red, green, blue, infrared, and is also a temperature sensor. The entire design fits onto a 6.5mm x 25mm printed circuit board (PCB).
The MAXREFDES44# subsystem provides a 1-Wire-based reference design for securing a Xilinx system-on-chip (SoC) to protect IP and prevent attached peripheral counterfeiting. The system implements a Public/Private Key 1-Wire ECDSA challenge-response between the SoC and a DS28E35 secure authenticator with on board memory. Boards for purchase, hardware, and firmware design files provide complete system information for rapid prototyping and development.
Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the poor performance that gave early video filters a bad reputation.

This document describes a microcontroller-based 1-Wire® master interface for reliable operation of small, medium, and large 1-Wire networks. This is accomplished using careful impedance matching, intelligent (software-controlled) active pullup, and slew-rate control. Software flow charts are included to assist the user in generating the correct 1-Wire timing for reset pulse, presence detect, write one, write zero, and read time slots using any suitable microcontroller. Scope traces illustrate the timing performance of the driver as well as transmission line effects as they appear with long cables.
