Radiation Resistance (TID, SEE)
Radiation Type | Description |
Total Dose (TID) Radiation | Resistance to permanent device damage caused by exposure to radiation (ions) over the life of the device. A trapped positive charge can result in field device turn-on. Infineon radiation-hardened SRAMs can operate up to a total dose of 300 Krad. |
Single Event Effects (SEE) | Loss of data and possible physical device damage caused by the impact of radiation particle (heavy ions, protons, or neutrons) which may result in device latch-up where a high current state is observed. |
QML-V & QML-Q Screening
QML certification is the highest standard of reliability for microcircuit devices issue by the United States government. This certification indicates that the device can be relied upon to function properly while being subjected to the harshest of conditions. Infineon’s radiation-hardened SRAMs feature both the QML-V and QML-Q certifications. |
Datapack
Infineon offers the option of purchasing a datapack with all QML-certified products. This datapack tabulates data gathered during the part certification process including radiation data, read and record electrical data, and tri-temperature test data. The datapack is offered in both hard and soft copy formats and is matched to individual part serial numbers.
Memory Controller
Memory controllers are available free of charge for Xilinx Virtex V5, Kintex US as well as for Microchip RTG4 FPGA’s for the RadHard 72M and 144M QDRII+ SRAM devices. The QDR-II+ SRAM controllers manage the intricate timing details of a DDR-based source synchronous timing architecture and ensure reliable data traffic between the FPGA and the QDRII+ SRAM memory. Controller embedded ECC (SECDEC) is also available as an RTL option if a higher level of radiation immunity is required to mitigate single event effects. Please contact hirel-memory@infineon.com for a copy of the RTL code and test bench.
