Microchip Expands its Radiation-Tolerant Microcontroller Portfolio with the 32-bit SAMD21RT Arm® Cortex®-M0+ Based MCU for the Aerospace and Defense Market
May 16 2024 - 7:00AM
Space exploration is experiencing a resurgence with exciting new
missions like the highly anticipated Artemis II mission, the recent
successful lunar landing missions such as JAXA SLIM and
Chandaaryan-3, and New Space deployments in Low Earth Orbit (LEO).
Designers require electronic components that meet stringent
radiation and reliability standards to operate in the harsh
environments found in space. Microchip Technology
(Nasdaq:
MCHP) today announces the
SAMD21RT, a
radiation-tolerant (RT) Arm® Cortex®-M0+ based 32-bit
microcontroller (MCU) in a 64-pin ceramic and plastic package with
128 KB Flash and 16 KB SRAM.
Designed for space-constrained applications where size and
weight are of critical importance, the SAMD21RT is available in a
small footprint of 10 mm × 10 mm. Running at up to 48 MHz, the
SAMD21RT delivers high-performance processing for harsh
environments. The device integrates analog functions including an
Analog-to-Digital Converter (ADC) with up to 20 channels, a
Digital-to-Analog Converter (DAC) and analog comparators.
The SAMD21RT device builds on Microchip’s existing family of
SAMD21 MCUs, which is widely used in industrial and automotive
markets. It is also based on Commercial-Off-The-Shelf (COTS)
devices, which significantly simplifies the design process when
transitioning to a radiation-tolerant device as the design remains
pinout compatible. Microchip offers a comprehensive system solution
for space applications with many devices that can be designed
around the SAMD21RT MCU including FPGAs, power and discrete
devices, memory products, communication interfaces and oscillators
providing a broad range of options across qualification levels.
To withstand harsh environments including radiation and extreme
temperatures, the SAMD21RT can operate in temperatures ranging from
−40°C to 125°C and provides a high level of radiation tolerance
with a Total Ionizing Dose (TID) capability up to 50 krad and
Single Event Latch-up (SEL) immunity up to 78 MeV.cm²/mg.
“The advantage of working with Microchip is that we have the
history, knowledge and capability to do the design and testing in
house for our radiation-tolerant and radiation-hardened devices,”
said Bob Vampola, vice president of Microchip’s aerospace and
defense business unit. “We continue to bring newer technologies
like Ethernet, AI and ML, which have evolved in the commercial and
industrial markets, and improve them with radiation performance to
meet the needs of space missions. We also continue to provide
higher computing performance and integration of newer technologies
into smaller packages, reducing weight and size.”
The low-power SAMD21RT features idle and standby sleep modes and
sleepwalking peripherals. Other peripherals include a 12-channel
Direct Memory Access Controller (DMAC), a 12-channel event system,
various Timer/Counters for Control (TCC), a 32-bit Real Time
Counter (RTC), a Watchdog Timer (WDT) and a USB 2.0 interface.
Communication options include Serial Communication (SERCOM), I2C,
SPI and LIN.
With tens of thousands of parts in orbit, Microchip has been a
significant part of space exploration history and is critical to
the missions of today and tomorrow. Its products are on the way to
the moon as part of the Artemis program and are contributing to the
success of the Space Launch System, Orion Spacecraft, Lunar
Gateway, Lunar Lander and next-generation spacesuits. To learn more
