Radiation-tolerant to 50 kilorads total ionizing dose,the SST38LF6401RT device enables systems to operate in a broad range of space applications.

CHANDLER, Ariz. – Microchip Technology Inc. in Chandler, Ariz., is introducing the SST38LF6401RT radiation-tolerant, 64-megabit parallel-interface SuperFlash memory device for maximum reliability and robustness in the harsh radiation environment of space missions.

The chip is a companion to Microchip's space-ready microcontrollers, microprocessors, and field-programmable gate arrays (FPGAs) that provide the building blocks for this scalable development model.

Radiation-tolerant to 50 kilorads total ionizing dose -- 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 also is a companion to the Microchip SAMRH71 Arm Cortex-M7-based radiation-hardened system-on-chip 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 transition to the space-qualified plastic or ceramic versions at the printed circuit board level. Voltage operation of the SST38LF6401RT ranges from 3 to 3.6 volts.

The SST38LF6401RT SuperFlash device is sampling 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.
