Device Overview

Summary

The SAM3X8ERT is the radiation tolerant version of the popular Microchip SAM3X8E high-performance 32-bit ARM Cortex-M3 processor. The SAM3X8ERT runs at 84MHz and features 512KB of flash memory in 2 x 256KB banks and 100KB of SRAM in 64KB +32KB banks, with an additional 4KB as NFC (NAND Flash controller) SRAM.

Its highly-integrated peripheral set for connectivity and communication includes Ethernet, dual CAN, High Speed USB MiniHost and device with on-chip PHY, high-speed SD/SDIO/MMC, and multiple USARTs, SPIs, TWIs (I2C), and one I2S. The SAM3X8ERT also features a 12-bit ADC/DAC, temperature sensor, 32-bit timers, PWM timer and RTC. The 16-bit external bus interface supports SRAM, PSRAM, NOR and NAND Flash with error code correction.

This space-qualified version of the product adds:  Ceramic & Hermetic packages, extended temperature range -40°C to 105°C, extended qualification flow equivalent to QML-V or QML-Q space grade.  Radiation performance for the SAM3X8ERT:  SEL LET > 62 MeV.cm2/mg (at 105°C), and TID up to 30 Krad (Si).
