RT Kintex UltraScale Radiation Characteristics

The space-grade XQR UltraScale™ architecture-based devices extend the benefit of commercial silicon with unique ceramic column grid array package, tested to stringent qualification flows like AMD B, Y test flows (QML compliant), full military operating temperature range support, and radiation tested for single-event effects. RT Kintex UltraScale device uses more than 40 proprietary, patented circuit design and layout techniques to reduce the SEU cross-section. The table below lists radiation characteristics for RT Kintex UltraScale.

Symbol Description Min Typ Max Units
TID Total Ionized Dose (GEO) - 100 120 Krad (Si)
SEL Single-Event-Latch-Up Immunity - 80 - MeV-cm2/mg
SEUCRAM Single-Event Upset in Configuration RAM (GEO) - 1.0e-8 - Upset/bit/day
SEUBRAM Single-Event Upset in Block RAM (GEO) - 8.5e-9 - Upset/bit/day
SEFICRAM Single Event Functional Interrupt Orbital Upset Frequency – Configuration RAM (GEO) - 4.5e-4 - Upset/device/day

The following table describes the types of Single Event Effects. For detailed reports visit the Space Lounge.

Radiation Type Radiation Signature Target/Comments
Single Event Upset (SEU) Corruption of the information stored in a memory element Memories, latches in logic devices. Composed of single bit upsets (SBU) or multiple bit upset (MBU).
Single Event Transient (SET) Impulse response of certain amplitude and duration Analog and mixed-signal circuits. Can lead to SEU if latched in memory cell.
Single Event Latchup (SEL) High-current conditions CMOS devices. Might lead to hard failure.
Single Event Functional Interrupt (SEFI) Corruption of a datapath leading to loss of normal operation Complex devices with built-in state machine/control sections or systems.
