Hi, Is it possible to have any mathematical dependencies, even approximate, between EEPROM FIT values and supply voltage? Thank you.

This might be a very basic question: EEPROM FIT values are based on standard single value of Ea = 0.7 eV. Is it irrelevant to supply voltage? I mean using lower supply for wide range device might reduce FIT values. Are any mathematical dependencies, ...

Hi, Does FIT of 2.4@90% 55°C/ ea=0.7 applies to higher reliability EEPROMs M24512-DRD3TP and M93C56-RDW3TP or they have has different FIT? Thank you!

Hi, I just got an answer for reliability of general parts EEPROMs M24512-DRD and M93C56-RDW. Thank you! Does 2.4@90% 55°C/ ea=0.7 applies to both _3TP and _6TP of M24512-DRD and M93C56-RDW, or M24512-DRD3TP and M93C56-RDW3TP has different FIT?

STM704 battery switchover vs UL60950

Hello,We are using two components with unique coin cell backup. The first one is a RTC M41T93SMY6. For this one, I could find AN1011 that states that we don't need external diode and resistor to meet UL60950, it is built in the chip. The second one i...

Dear, we have a problem whith some ST485BDR. When the 120 ohm load resistor is applied, the pin 1 goes to low state, lighting the green RX LED

This board perform 4 channels UART to RS485/422 conversion, using a FT4232 device and four ST485BDR devices. The issue is present in some channels in aleatory way. When I replace the failed ST485BDR device by the MAX485ESA the issued chanel start to ...
