Rad-Tolerant MCUs Target Aerospace and Defense Markets
To address New Space deployments in Low Earth Orbit (LEO), Microchip Technology released the SAMD21RT, a radiation-tolerant Arm Cortex-M0+-based 32-bit microcontroller in a 64-pin ceramic and plastic package with 128-kB Flash and 16-kB SRAM. Presenting a footprint of 10 × 10 mm, the SAMD21RT operates at up to 48 MHz, providing high-performance processing in harsh environments. Integrating analog functions including an ADC with up to 20 channels, a DAC, and analog comparators.
Building on Microchip’s existing family of SAMD21 MCUs, the SAMD21RT can operate in temperatures ranging from −40 to 125°C and a total ionizing dose (TID) capability up to 50 krad and single-event latch-up (SEL) immunity up to 78 MeV.cm²/mg. Features include idle and standby sleep modes and peripherals that include a 12-channel direct-memory-access controller, a 12-channel event system, various timer/counters for control, a 32-bit RTC, a watchdog timer, and a USB 2.0 interface.
Communication options include Serial Communication (SERCOM), I2C, SPI, and LIN, and support includes the SAM D21 Curiosity Nano Evaluation Kit, MPLAB X Integrated Development Environment, and MPLAB PICkit 5 in-circuit debugger/programmer.
