The new product enriches the processor and communication interface based on cots, and simplifies the development of aerospace level and scalable overall system solutions

In order to reduce the time, cost and risk of developing spacecraft system, designers can use commercial off the shelf (COTS) at the initial stage, and then replace it with aerospace equivalent radiation resistant devices with the same pin distribution and plastic or ceramic package. Microchip Technology Inc. today announced the launch of a radiation resistant 64 megabit (Mbit) parallel interface superflash flash device, which has excellent total ionizing dose (TID) tolerance and can achieve maximum reliability and durability in harsh space radiation environment. The new product is an ideal accessory of MCU, MPU and FPGA used in aerospace system by microchip. It provides a building module for this extensible development model.

Bob vampola, vice president of aerospace and defense business department of microchip, said: “in the process of using our radiation resistant or radiation resistant microprocessor and FPGA to develop the overall solution of aerospace system, sst38lf6401 rtsuperflash product has further enhanced its scalability. The aerospace system needs supporting flash memory to store the key software code or bit stream driving the whole system, which is very important for digital processing The reliability requirements of the new product are very high, and the new product provides the key protection for this process. “

The radiation tolerance of sst38lf6401rt is as high as 50 kilorads (krad) TID even when flash memory is still in power supply and running state. The product can make the system run in various space applications. In these applications, the system can not bear any code execution errors, otherwise it may lead to serious defects and system crash. The new product is an ideal accessory for microchip’s radiation resistant SOC processor based on samrh71arm? Cortex? – M7. It can also be used with rtpolarfire? FPGA to support the reconfiguration of spacecraft onboard system. The new product has compatible pin distribution with its industrial version, so that it can be easily replaced with aerospace grade plastic or ceramic package version on printed circuit board (PCB). The operating voltage range of sst38lf6401rt is 3.0 to 3.6 v.

Development tools and supplies

Sst38lf6401 rtsuperflash devices are now available with ceramic packaging samples. Evaluation boards and demonstration software can be provided on request. In addition, FPGA flight programming reference cases can be provided to demonstrate how to integrate superflash devices with FPGA and samrh71 processors through supporting software.

Microchip technology from cots to radiation resistant products

By improving the silicon process of related devices in its mature and reliable automotive or industry standard product line, microchip can provide enhanced protection for these devices from single event latch up in heavy ion environment. By providing a special radiation report for each functional block, the radiation performance of these devices with a small amount of modification is fully characterized. These devices are widely used in launch vehicles, satellite networks and space stations. Designers can start system deployment with easily accessible cots devices, and then replace them with pin compatible Aerospace class devices in highly reliable plastic or ceramic packages.
