The SST26LF064RT memory device is the second SuperFlash offering® from Microchip qualified for space,
Spaceflight-qualified system designers have a tremendous need to reduce development time, cost, and risk in their systems. Microchip Technology Inc. proposed the concept of starting with off-the-shelf devices and later replacing them with their space-qualified, radiation-tolerant (RT) equivalents. Microchip announces today that it has expanded its family of SuperFlash® radiation-tolerant, commercial-based products for these applications and brings its unmatched tolerance to a 50 kilorad (krad) Total Ionizing Dose (TID) to a 64 Mbit serial NOR flash with four I/Os for use in harsh environments of aerospace and defense systems.
“The SST26LF064RT SuperFlash device provides the best TID on the market for a 64-I/O XNUMX Mbit serial memory solution that works with any SRAM-based FPGA in a variety of space applications,” said Bob Vampola, associate vice president of Aerospace and Defense at Microchipped. “It is ideal for systems used in LEO (Low Earth Orbit) constellations and other environments subjected to intense radiation that require flash memory to store critical software code or the bit stream that drives the entire system.”
Microchip's NOR SuperFlash memory products use a proprietary split gate cell architecture to improve performance, data retention and reliability compared to conventional stacked gate flash. They take the complexity out of switching power management to achieve the highest TID on the market even with flash polarized and running in systems like satellite on-board computers and different types of controllers for motors, sensors, solar panels and distributed power.
Microchip's SuperFlash RT technology, which has been proven in industrial applications, is delivered in a parallel interface solution on its 38 Mbit SST6401LF64RT device, now space-qualified and available for flight models. Thanks to the SST26LF064RT product, designers now have a 64 Mbit serial memory with four I/Os.
An application note explains how to use the 64 Mbit serial SuperFlash device with Microchip's SST26LF064RT RT flash reference evaluation board and space-qualified SRAM-based FPGAs. Like Microchip's Parallel SuperFlash memory, Serial SuperFlash can also be used as configuration memory with an FPGA and other Microchip solutions such as the Arm-based SAMRH707 microcontroller.® Cortex®-M7 and radiation resistant. Can also be used with the PolarFire RT FPGA® to reconfigure the system in flight.
