Serial 64-Mbit SuperFlash Reminiscence Extends Choices

Designers of spaceflight-qualified programs have an ideal want to cut back improvement time, value and danger of their programs. Microchip Expertise Inc. proposed the idea of beginning with Industrial-Off-The-Shelf (COTS) units after which changing them with space-qualified, Radiation-Tolerant (RT) equal components. Microchip at the moment declares it has prolonged its household of COTS-based, RT SuperFlash choices for these functions and is bringing the Microchip reminiscence expertise’s unmatched 50 kilorad (krad) Complete Ionizing Dose (TID) tolerance to a 64-Mbit serial quad I/O NOR flash reminiscence machine to be used in harsh aerospace and protection system environments.

“The SST26LF064RT SuperFlash machine brings the most effective TID efficiency in the marketplace to a 64-Mbit serial quad I/O reminiscence resolution that works alongside any SRAM-based FPGA in various house functions,” mentioned Bob Vampola, affiliate vp of Aerospace and Protection at Microchip. “It’s perfect for programs utilized in Low Earth Orbit (LEO) house constellations and different harsh radiation environments the place companion flash reminiscence is required for storing the vital software program code or bitstream that drives the whole system.”

Microchip SuperFlash NOR flash reminiscence merchandise use a proprietary split-gate cell structure to enhance efficiency, information retention and reliability as in comparison with standard stacked gate flash. They eradicate the complexity of energy administration switching to attain their business excessive TID even whereas the flash remains to be biased and working in programs equivalent to satellite tv for pc on-board computer systems and various kinds of controllers for motors, sensors, photo voltaic panels and energy distribution. Confirmed in industrial functions, Microchip’s RT SuperFlash expertise has been provided as a parallel-interface resolution with its 64-Mbit SST38LF6401RT machine that’s now space-qualified and accessible in-flight fashions. With the SST26LF064RT product, designers now even have a serial quad I/O 64Mbit reminiscence choice. 

An utility notice explains methods to use the serial 64-Mbit SuperFlash machine with Microchip’s SST26LF064RT RT flash reference analysis board and space-qualified SRAM-based FPGAs. Like Microchip’s parallel SuperFlash reminiscence, the serial SuperFlash choice can be used as configuration reminiscence with an FPGA and different Microchip options such because the Arm® Cortex®-M7- based mostly SAMRH707 radiation-hardened microcontroller (MCU). It can be used with the RT PolarFire FPGA to assist in-flight system reconfiguration.
