Microchip SAMD21RT
SAMD21RT - Radiation Tolerant, Low-Power, 32-bit Cortex-M0+ MCU with Advanced Analog and PWM
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.
