Maxim Integrated Releases Secure IoT Microcontroller with ChipDNA PUF Key Protection Technology

Posted on by mixos

MAX32520 provides the most secure boot for root-of-trust to protect connected healthcare, industrial and computing systems

Maxim has released the MAX32520 ChipDNA™ secure Arm® Cortex®-M4 microcontroller, the first secure microcontroller with built-in physically unclonable function (PUF) technology for financial- and government-grade security. Maxim Integrated’s PUF technology allows for multiple layers of protection to provide the most advanced key-protection technology in a cost-effective format for use in IoT, healthcare, industrial and computing systems.

As IoT applications continue to proliferate, large numbers of devices are being deployed in uncontrolled and hostile areas that make them more vulnerable to physical attacks. These are more sophisticated than software threats like poor crypto implementations or default password attacks. Designers want enhanced system defenses for their mission-critical applications where exposing secret encryption keys can bring down networks, ruin reputations, end companies and even negatively affect people’s lives.

IoT developers are eager to add security to their designs but they are hard-pressed to find the expertise needed to get them to market with advanced protection, said Tanner Johnson, senior analyst, IoT Cybersecurity at Omdia. Enabling developers to incorporate PUF-encrypted flash and secure boot loading without system redesign or in-house code development will help them reduce time-to-market dramatically.

The MAX32520 with ChipDNA offers multiple layers of protection through its PUF technology, the industry’s most advanced key-protection technology for safeguarding secrets used in cryptographic operations. It uses a tamper-proof PUF key for flash encryption, secure boot for root-of-trust and serial flash emulation. Additionally, the physical security inherent in the PUF key eliminates the need for a battery to actively destroy secret-key materials when under attack. Until now, the most-sensitive applications have always required a battery to provide this highest level of secret-key protection.

The threats to IoT systems are getting more advanced all the time, and tools to attack systems move from the realm of academia to the realm of open source every day, said Kris Ardis, executive director, Micros, Security and Software Business Unit at Maxim Integrated. MAX32520 with ChipDNA is a step forward. Built around the most advanced key security technology and targeting IoT applications, it will protect your data and IP, and has the technology to future-proof designs against tomorrow’s system threats.

LadyBug: The High-Quality Motorized Microscope and 3D Scanner

Posted on by Emmanuel Odunlade

Imagine that you wanted to take a picture of a very small object and you still need to zoom in as much as possible to get the smallest detail of the picture. If you have been at this stop before, then you obviously did not try taking the whole picture at once. You must have tried using a number of motors to move the object or the camera while you take a couple of pictures and then join the parts together or probably even tried doing 2D scanning a lot of times where each time you pause to take a picture, you take as many as you need to cover the object at the right resolution. All these options are good, but are not the best options that can be — they are time-consuming and can introduce subtle distortions in your image.

“Ladybug is a picture-based 3D scanner, meaning that it’s primary function is to take photographs of an object from all sides, which can then be turned into a 3D model. What’s special about it is what it takes the picture with, how it takes the pictures, and what it’s made of. First, it uses a high-powered USB microscope, which is both cheap and effective — as long as you’re just looking at a tiny part of the object! LadyBug solves this by using motors to do 3D scanning on top of 2D scanning”, writes Noselace about the miniature microscope and 3D scanner.

Made almost entirely out of Blu-Ray players and 3D printed parts, the Ladybug is a 4-axis motorized microscope and a 3D scanner for extremely small objects. The camera system is made up of a low-cost USB microscope powered by a Raspberry Pi that makes it easy to capture details less than 10 microns. The LadyBug can also be set up to perform 2D scanning as long as it fits into the platform you are working with.

Because :

“it’s very common in academia to spend years building or discovering something and then have absolutely no one to try replicate your work”,

Noselace has decided to publish a full guide in Instructables format so that those interested in building their own LadyBug microscope and 3D scanner can simply slide into the project’s official Instructables page for further instructions. Hopefully, the LadyBug would be a “serious tool for photographers, teachers, and scientists” in the nearest future.

More information on the LadyBug can be found on its GitHub repository. Also, there is a Kickstarter campaign running and has 27 days to go.

ESP32 Burninator is a tiny laser engraver

Posted on by Emmanuel Odunlade

As the name implies, a linear stepper is linear a variation of the rotary stepper motor design, radially cut and laid out flat. It is similar to the rotary version in operation and performance, and it typically runs as an open-loop system with the ability to provide high resolution at high speeds and accelerations.

As a way of experimenting with a few linear stepper motors from Aliexpress, Mike-Rankin recently decided to build a laser engraver which he called the ESP32 Burninator. The device, whose name was inspired by Mike’s long time fandom of the homestarrunnerdotcom videos, at its core comprises of an ESP32,  two linear stepper motors, and a DVD burning laser diode.

Mike developed a custom board for the project, designing his own ESP32 board with the components arranged in a way that suits all the other elements of the project.  While the stepper motors lacked the level of strength that could make them useful for cutting or drawing, they have just enough strength to serve as the arm that is used to move the DVD burning laser diode, and also serve as the base on top of which the paper to be engraved on was placed.

For focussing the laser, a tiny adjustable lens from the popular laser diodes used in several Arduino projects was savaged by pulling out the visible diode component and replacing it with the DVD diode.

While Mike seems to think the project is not of any useful importance, I believe designers will find a lot of useful information, reusable codes, schematics, etc., from the amazing work done by him.

The project is fully open-source and all documents including schematics, PCB, firmware, and assembly video, are available on the project’s Github page.

TinyRemote Control implements NEC protocol with Attiny13

Posted on by Emmanuel Odunlade

The ATtiny series of microcontrollers are becoming popular as more people begin to learn about the huge capabilities packed into their tiny form factors and the possibility of easy programming through several modern tools like the Arduino IDE and PlatformIO. As a result of this popularity, several new devices, DIY or not, are now springing up with one version of the Attiny series or the other at the heart of it.

One of such recent devices is the Attiny13 based TinyRemote by Stefan Wagner. TinyRemote is an IR remote control based on an ATtiny13A powered by a CR2032 or LIR2032 coin cell battery. It comes with 5 pushbuttons which can be designated to serve different purposes on the receiver.

The ATtiny13 on which the device is based is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture, capable of executing powerful instructions in a single clock cycle, achieving a throughput of around 1 MIPS per MHz. This allows system designers to optimize power consumption versus processing speed and makes it a good fit for a remote control device like the tinyRemote where low power consumption is a top priority.

The project is completely open-source and all files including Schematics, PCB, BOM, and even the firmware is provided by Stefan on the project’s page. The device was professionally designed with attention to detail and the capabilities of the components used. For instance, the firmware features a full implementation of the NEC protocol using only 370 bytes (36%) of program memory. More information on the project along with the design files can be found on the project page on EasyEDA.

Skytraq Launches Tiny PX1122R Multi-Band RTK GNSS Module, Enabling Centimeter Accuracy

Posted on by Tope Oluyemi

A couple of years ago Skytraq launched the NavSpark mini, a tiny (17x17mm) GPS module, that sold for $6. However, the company has now launched an even smaller module called Skytraq PX1122R, which  measures at just 16x12mm, and offers support for GPS, Galileo, GLONASS, and Beidou signals, as well as Real-time Kinematic (RTK) relative positioning technique that enables 1-3cm positioning accuracy.

The Skytraq PX1122R RTK GNSS module key features a SkyTraq PX100 Phoenix GNSS chipset. It Supports GNSS standards & bands – GPS L1/L2C, Galileo E1/E5b, Beidou  B1I/B2I, GLONASS L1/L2, QZSS L1/L2C. Its Integrated RTK offers 1cm + 1ppm RTK accuracy in seconds (under 10 seconds),  enhancing the precision of position data derived from satellite-based positioning systems. The module enables Up to 10Hz quad-GNSS RTK update rate. The module also enables Base or rover, which have a mode configurable. The module offers 3V LVTTL level for serial interface, 24x castellated holes with UART, RF input, 1PPS, Reset, 3.3V, GND (most pins not in use). Input Voltage clocks at 3.3V DC +/‐10%, while consuming 50mA of current. It is 16 x 12.2 mm in dimension, and weighs 1.7 grams, with a temperature Range of ‐40°C ~ +85°C.

Application to the module’s centimeter-level precision includes: agriculture, machine control guidance (UAV), survey and GIS data collection, structure, and deformation monitoring. RTK applications need a base and a rover. The base can be a third-party RTK base station service, or a configured PX1122R module. The PX1122R module is also suitable for PPP services like OPUS, AUSPOS, CSR-PPP. This functions by presenting a dual-frequency RINEX log file converted from carrier phase raw measurement log file of a single PX1122R.

Skytraq PX1122R Breakout board

The company provides a breakout board to help get started with the module, and also PX1122R-EVB “PX1122R Multi-Band Quad-GNSS RTK Evaluation Board” with USB, UART, and Bluetooth SPP (Serial Port Profile) interface. The Bluetooth SPP interface enables rover NTRIP client connection to remote non-line-of-sight RTK base through a smartphone connected to the Internet and running a mobile app like ArcPad or Esri Collector.

PX1122R-EVB

Skytraq PX1122R mass-production started last month. Even though the RTK positioning looks promising, the RTK module and boards will be available at a much higher price, with PX1122R priced at $99, while the breakout board is priced at $125, and the evaluation board is priced at $150. You can find all three on Navpark Store. More details including a getting started guide, a datasheet, GNSS viewer program, and firmware can be found on the various product pages on the store.
