Microchip adds SuperFlash Memory to COTS-based devices for space systems

Microchip Technology has launched a radiation-tolerant, 64Mbit parallel-interface SuperFlash memory device that's capable of operating in the harsh radiation environment of space missions.

Radiation-tolerant up to 50 kilorad (krad) TID, even while the Flash is still biased and operating, the SST38LF6401RT device enables systems to operate in a broad range of space applications where they cannot afford any loss of code execution that could lead to severe defects and system loss.

It has been designed as a companion to Microchip’s SAMRH71 Arm Cortex -M7-based radiation hardened SoC processor and can also be used with the company’s RT PolarFire FPGAs to support in-flight system reconfiguration.

The device has pinout distribution compatibility with its industrial version for easy transition to the space-qualified plastic or ceramic versions at the Printed Circuit Board (PCB) level. Voltage operation of the SST38LF6401RT ranges from 3.0 to 3.6 volts (V).

The SST38LF6401RT SuperFlash device is sampling now in a ceramic version and supported by an evaluation board and demonstration software, available upon request. Also available upon request is an FPGA flight programming reference case for combining the SuperFlash device with an FPGA and a SAMRH71 processor with supporting software.
