Microchip grows rad-tolerant MCU portfolio
Offering high radiation tolerance, the SAMD21RT MCU from Microchip is capable of operating in the harsh environments found in space. The device, which is based on a 32-bit Arm Cortex-M0+ core running at up to 48 MHz, also meets the stringent size and weight constraints critical for space applications.
The SAMD21RT operates over a temperature range of -40°C to +125°C and tolerates up to 50 krads of total ionizing dose (TID) radiation. It also provides single event latch-up (SEL) immunity of up to 78 MeV.cm2/mg. Operating voltage is 3 V to 3.6 V.
Occupying a footprint of just 10×10 mm, the SAMD21RT MCU packs 128 kbytes of flash memory and 16 kbytes of SRAM in its 64-pin plastic or ceramic QFP package. It furnishes multiple peripherals, including a 12-bit ADC with up to 20 channels, a 10-bit DAC, 12-channel DMA controller, two analog comparators, and various timer/counters. To conserve power, the SAMD21RT offers idle and standby sleep modes.
Limited samples of the SAMD21RT microcontroller are available by contacting a Microchip sales representative.
