SBOK061 October 2022 SN54SLC8T245-SEP
SETs are defined as heavy-ion-induced transients upsets on VOUT of the TPS7H1210-SEP. SET testing was performed at around 25°C. The species used for the SET testing was a Silver (109Ag) ion with an angle-of incidence of 0° for an LETEFF = 43 MeV·cm2 /mg. Flux of approximately 9.6× 103 to 1.1 × 104 ions/cm2 ·s and a fluence of approximately 1 × 106 ions/cm2 were used for the twelve SET runs.
Figure 3-2 shows the three main scenarios that were tested. The device was configured with clock signals ranging from 100 kHz to 5 MHz as inputs for channels A2 and A7.
