Microchip’s Radiation Hardened (Rad-Hard) Space-Grade DC-DC Converters

The Microchip SA50-28 family is the space industry’s only standard, non-hybrid space-grade power converters – it now includes 28 Volt (V)-input, 50-watt (W) radiation-tolerant options.


Traditional hybrid-style power converters may have a limit on non-standard voltages and functions, creating complex challenge for space system designers; however, these have been eliminated by Microchip’s discrete-component-based, space-grade DC-DC power converter family – which are much more flexible and customisable – greatly simplifying and accelerating system development compared to alternative space-grade power converters. It’s the industry’s only off-the-shelf 28V-input, radiation-tolerant power converter with surface-mount construction and non-hybrid assembly processes.

Microchip’s comprehensive SA50-28 line is a 20V- to 40V-input, 50W family with nine standard outputs of 3.3V, 5V, 12V, 15V and 28V in single- and triple-output configurations. The devices can be tailored to a system’s exact power needs quickly with minimal additional costs as compared to hybrid-style power converter products. Other features include high efficiency, low output noise, output inhibit control, overcurrent protection, external synchronisation, and full-rated power operation through −55°C to +85°C with linear derating to +125°C.

These space-grade products that have join the rad-hard SA50-120 power converter family (introduced in February 2021) now reduce risk and development time for qualified space systems by allowing designers to start with proven commercially available off-the-shelf technology in ceramic or plastic packages and quickly scaling up development using lower screening levels than traditional Qualified Manufacturers List (QML) requirements.

    Power Access Control Systems Using Microchip mPoE

    Access control systems are used to monitor and manage access to premises. They provide quick access to authorised personnel and deny access to those otherwise. This is its conventional purpose. Due to the current COVID-19 pandemic, access control systems features have advanced to enhance the health and safety of a premise. This is done by:

    • Ensuring a strict number of occupants in a premise at a certain time, such as an office, retail space, etc.
    • Granting contactless entry/exit and eliminating the physical touch points
    • Trigger ‘no mask’ alarms using camera-based systems
    • Restrict access to infected people or those who have not completed their quarantine period

    What Powers These Systems?

    Power over Ethernet (PoE) is a technology that enables the delivery of safe and intelligent power along with data over standard Ethernet infrastructure to install IP-based systems quick and easily.  Many access control systems have the option to be powered by PoE.

    A few advantages of using PoE to power access control systems are:

    • PoE technology is an international power standard that delivers safe, low-voltage DC power and eliminates dependency on the AC infrastructure, as well as specific regional plugs
    • Cost savings from eliminating the need for separate data and power infrastructures, searching for AC outlets or certified technicians
    • Able to connect quickly and seamlessly in any location
    • No need to physically plug/unplug the power; the control is centralised, and the power can be reset remotely
    • Power delivered over the standard Ethernet network is technically safe however it will not power up until a valid PD is detected, thus, protecting non-PoE devices

    Microchip multi-Power over Ethernet (mPoE) is the key to efficient, cost-effective and reliable power in network access control systems:

    • Quick, seamless installation: plug-and-play solutions for zero time to market in the most demanding environments
    • High power: deliver up to 90W of power, enabling most comprehensive access to control devices to be powered by PoE
    • Diver applications: supports a wide variety of applications using single-ports to 24-ports, indoor, outdoor and industrial rated solutions
    • Backward compatibility: leveraging a uniquely designed algorithm, the solutions are compatible with pre-standard devices while supporting all IEEE® PoE standards
    • Regulatory compliance: Microchip mPoE midspans and switches go through the necessary worldwide certification and safety approvals
    • Vendor agnostic: supports a variety of access control terminals already in the market

    Microchip mPoE offers a comprehensive end-to-end portfolio of PoE solutions comprised of PoE ICs and PoE systems (midspans/injectors and switches).

    Microchip Capacitive Touchscreen Controller

    World’s First Safety-Certified Capacitive Touchscreen Controller Family from Microchip

    As standard, emergency stop and unlock buttons are safety mechanisms in home appliances (e.g. ovens, hobs, washing machines, tumbler driers, etc.) are necessary help reduce the risk of fires and floods in homes.

    Microchip’s maXTouch MXT336UD-MAUHA1 new family offers IEC/UL 60730 Class B pre-certified solutions that meet functional safety requirements whilst eliminating the need for a separate emergency stop or unlock buttons on touchscreen appliances. They are the only touchscreen controllers to offer pre-certified, Class B firmware on the market.

    The touch controllers offer a unique safety feature that enables the system to shut off through an intuitive soft button on a touchscreen. This removes the requirement for an external stop/cancel button, and associated microcontroller (MCU). The maXTouch MXT336UD-MAUHA1 also allows an appliance to detect a touchscreen/appliance failure and shuts down automatically through self-testing capabilities. For example, if the glass on an electric hob breaks, the touchscreen will darken and shut off the machine – minimising any accidental damage in the home.

    The number of touch-enabled home appliance is growing; the MXT336UD-MAUHA1 family is progressing in this direction, offering OEMS reduced costs and improving time-to-market with this simplified, single touchscreen interface.

    The family consists of three controllers: the MXT112UD-MAUHA1, the MXT228UD-MAUHA1 and the MXT336UD-MAUHA1; each of one these fulfil various screen size requirements, ranging from 2 to 8 inches.

    “Due to the risk of house fires caused by home appliances, appliance manufacturers must add functional safety to their machines, and Microchip’s MXT336UD-MAUHA1 touchscreen controller family is already certified for these required safety standards,” said Fanie Duvenhage, Vice President of Microchip’s Human Machine Interface business unit. “Integrating Class B certification into our touch controllers eases the design and qualification process for touch enabled appliances, ultimately putting safety first, while reducing costs and enabling modern user interface solutions.”

    Introducing Microchip’s NOR Flash Memory Devices with Embedded MAC Address



    Introducing Microchip’s new family of low-power, high-performance memory devices: Microchip NOR Flash Memory devices that are pre-programmed with MAC addresses to reduce production costs and time to market, available to businesses of all sizes.


    In the growing world of Internet of Things (IoT), embedded system designers must currently source, program and serialise Media Access Control (MAC) addresses from the IEEE-Registration Authority (RA) for all connected products. Small to medium-sized businesses have to pay higher costs for low-volume services, sold from the IEEE-RA in blocks ranging from 4000 to 16 million; the new Microchip NOR Flash Memory devices do not have a minimum order requirement. By eliminating the need to self-procure and manage unique identifiers from the IEEE-Registration Authority (RA), Microchip will help designers save time and costs, whilst accelerating time to market. This makes it ideal for low to mid-sized volume production.


    These devices are suitable for cloud-connected applications, such as smart hubs for homes, smart home appliances, building control equipment, factory automation, security and surveillance equipment, and many more.


    The Microchip SST26VF Serial Quad I/O™ (SQI™) 3V Flash family is the industry’s first NOR Flash device that offers integrated MAC address options; Microchip’s latest NOR Flash devices can be pre-programmed with EUI-48™ and EUI-64™ addresses, making it a cost-effective, plug-and-play solution for connect applications that use Ethernet, Bluetooth®, Wi-Fi®, IEEE 802.15.4 and FireWire®.


    The SST26VF064BEUI, SST26VF032BEUI and SST26VF016BEUI are low-power, high-performance devices in a low pin-count package, featuring a six-wire, 4-bit I/O interface.



    These are available in 8-pin SOIC and 8-contact WSON packages, occupying less board space and lowering overall system costs. Microchip’s pre-programmed SST26VF family of devices are flexible MAC address chips that come with uniquely pre-programmed EUI- 48 addresses and compatible EUI-64 addresses. MAC address options are available at Flash densities of 16 megabit (Mb), 32Mb and 64Mb. They feature rich SQI flash, with flexible write-protected functionality to eliminate accidental over-writing or erasure. Both the EUI-48 and EUI-64 node addresses consist of an Organizational Unique Identifier (OUI) and an Extension Identifier (EI). While the OUI is purchased from the IEEE by individual companies, the EI is assigned and managed through each company by building a unique EI into every product, thereby ensuring a globally unique Extended Unique Identifier (EUI) node address for every device used or shipped.


    Overall, with the Microchip SST26VF Serial Quad I/O™ (SQI™) 3V Flash family:

    • You don’t need to buy MAC addresses
    • You don’t have to manage MAC addresses
    • You don’t need to program MAC addresses
