Microchip Adds 64 Mbit Parallel SuperFlash Memory
Microchip Technology has added a radiation-tolerant, 64 Megabit (Mbit) parallel-interface SuperFlash memory device with un-rivaled Total Ionizing Dose (TID) tolerance for maximum reliability and robustness in the harsh radiation environment of space missions.
It is an ideal companion to Microchip’s space-ready microcontrollers (MCUs), microprocessors (MPUs) and Field Programmable Gate Arrays (FPGAs) that provide the building blocks for this scalable development model.
“The SST38LF6401RT SuperFlash memory device further strengthens our scalable approach to developing total space system solutions using our radiation-tolerant or radiation-hardened microprocessors and FPGAs,” said Bob Vampola, associate vice president of Microchip’s aerospace and defence business unit. “It offers the vital protection these space systems need for the most reliable digital processing where companion Flash memory is required to store the critical software code or bit stream that drives the complete system.”
Radiation-tolerant up to 50 kilorad (krad) TID, 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 is an ideal companion to Microchip’s SAMRH71 Arm Cortex-M7-based radiation-hardened SoC 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 an easy transition to the space-qualified plastic or ceramic versions at the Printed Circuit Board (PCB) level. Voltage operation of the SST38LF6401RT ranges from 3.0 to 3.6 volts (V).
