Infineon extends line of radiation-hardened asynchronous static RAMs

Edge computing and inference in satellites enables near real-time data analysis and decision making and is becoming increasingly important as the number of connected devices and the amount of data they generate continue to grow.

To address these high-performance computing requirements in space applications, Infineon Technologies LLC Memory Solutions is making available its latest radiation-hardened (rad hard) asynchronous static RAMs designed with Infineon’s patented RADSTOP technology. These new products are designed for use in space and other harsh environment applications where high reliability and performance are critical.

Data buffering in high performance space computing requires more memory than the on-chip memory of an MCU or FPGA can provide. The memory must also provide a higher level of performance for real-time processing applications and have superior radiation performance to meet mission requirements in harsh environments.

Infineon’s new rad hard SRAMs are available in 8-, 16- and 32-bit wide configurations and offer embedded error correction code (ECC) for single-bit error correction. This advanced technology enables the ECC logic to detect and correct single-bit errors in any read data word during the read cycles.

Infineon’s RADSTOP technology is rad hard through proprietary design and process hardening techniques, meeting all radiation requirements for extreme environments.

The new rad hard memories are QML-V certified, ensuring the reliability and lifecycle requirements of extreme environments. The devices feature access times down to 10 ns, making them the fastest option available. According to Infineon, they also offer the smallest footprint for the highest density and lowest quiescent current.

RADSTOP memory solutions extend the computing limits of the overall system, while offering size, weight and power advantages for greater design flexibility.
