Microchip unveils second SuperFlash offering to be space-qualified

Microchip has extended its family of COTS-based, RT SuperFlash options and is bringing its 50 kilorad (krad) Total Ionizing Dose (TID) tolerance to a 64-Mbit serial quad I/O NOR flash memory device for use in harsh aerospace and defence system environments.

The SST26LF064RT SuperFlash device is intended for systems used in Low Earth Orbit (LEO) space constellations and other harsh radiation environments where companion flash memory is required for storing the critical software code or bitstream that drives the complete system.

Microchip SuperFlash NOR flash memory products use a proprietary split-gate cell architecture to improve performance, data retention and reliability as compared to conventional stacked gate flash. They eliminate the complexity of power management switching to achieve their industry high TID even while the flash is still biased and operating in systems such as satellite on-board computers and different types of controllers for motors, sensors, solar panels and power distribution.

Microchip’s RT SuperFlash technology has been offered as a parallel-interface solution with its 64-Mbit SST38LF6401RT device that is now space-qualified and available in-flight models. With the SST26LF064RT product, designers now also have a serial quad I/O 64Mbit memory option.

Like Microchip’s parallel SuperFlash memory, the serial SuperFlash option can also be used as configuration memory with an FPGA and other Microchip solutions such as the Arm Cortex-M7- based SAMRH707 radiation-hardened microcontroller (MCU). It can also be used with the RT PolarFire FPGA to support in-flight system reconfiguration.
