Microchip Expands its Radiation-Tolerant Microcontroller Portfolio with the 32-bit SAMD21RT Arm Cortex-M0+ Based mostly MCU for the Aerospace and Protection Market

The SAMD21RT MCU is obtainable in 64-pin ceramic and plastic packages with a ten mm × 10 mm footprint

Area exploration is experiencing a resurgence with thrilling new missions just like the extremely anticipated Artemis II mission, the latest profitable lunar touchdown missions corresponding to JAXA SLIM and Chandaaryan-3, and New Area deployments in Low Earth Orbit (LEO). Designers require digital parts that meet stringent radiation and reliability requirements to function within the harsh environments present in area. Microchip Expertise  right this moment publicizes the SAMD21RT, a radiation-tolerant (RT) Arm Cortex-M0+ primarily based 32-bit microcontroller (MCU) in a 64-pin ceramic and plastic package deal with 128 KB Flash and 16 KB SRAM.

Designed for space-constrained purposes the place measurement and weight are of crucial significance, the SAMD21RT is obtainable in a small footprint of 10 mm × 10 mm. Operating at as much as 48 MHz, the SAMD21RT delivers high-performance processing for harsh environments. The gadget integrates analog capabilities together with an Analog-to-Digital Converter (ADC) with as much as 20 channels, a Digital-to-Analog Converter (DAC) and analog comparators.

The SAMD21RT gadget builds on Microchip’s current household of SAMD21 MCUs, which is broadly utilized in industrial and automotive markets. It’s also primarily based on Industrial-Off-The-Shelf (COTS) gadgets, which considerably simplifies the design course of when transitioning to a radiation-tolerant gadget because the design stays pinout suitable. Microchip affords a complete system answer for area purposes with many gadgets that may be designed across the SAMD21RT MCU together with FPGAs, energy and discrete gadgets, reminiscence merchandise, communication interfaces and oscillators offering a broad vary of choices throughout qualification ranges.

To resist harsh environments together with radiation and excessive temperatures, the SAMD21RT can function in temperatures starting from −40°C to 125°C and gives a excessive degree of radiation tolerance with a Whole Ionizing Dose (TID) functionality as much as 50 krad and Single Occasion Latch-up (SEL) immunity as much as 78 MeV.cm²/mg.

“The benefit of working with Microchip is that we now have the historical past, data and functionality to do the design and testing in home for our radiation-tolerant and radiation-hardened gadgets,” stated Bob Vampola, vice chairman of Microchip’s aerospace and protection enterprise unit. “We proceed to carry newer applied sciences like Ethernet, AI and ML, which have developed within the business and industrial markets, and enhance them with radiation efficiency to fulfill the wants of area missions. We additionally proceed to supply greater computing efficiency and integration of newer applied sciences into smaller packages, lowering weight and measurement.”

The low-power SAMD21RT options idle and standby sleep modes and sleepwalking peripherals. Different peripherals embody a 12-channel Direct Reminiscence Entry Controller (DMAC), a 12-channel occasion system, varied Timer/Counters for Management (TCC), a 32-bit Actual Time Counter (RTC), a Watchdog Timer (WDT) and a USB 2.0 interface. Communication choices embody Serial Communication (SERCOM), I²C, SPI and LIN.

With tens of 1000’s of components in orbit, Microchip has been a major a part of area exploration historical past and is crucial to the missions of right this moment and tomorrow. Its merchandise are on the way in which to the moon as a part of the Artemis program and are contributing to the success of the Area Launch System, Orion Spacecraft, Lunar Gateway, Lunar Lander and next-generation spacesuits.
