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...
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 ...
Hi,Because of my PCB design, the NC pins of M24C08 eeprom are connected to GND. Would this cause any problem ? Any advise ?
Testing some old transistors for a customer and parts are marked with a FB ending. These are 1997 parts . Anyone know what that calls out? Is it factory burn in? also can't find a ST datasheet for these if anyone has one LMK.
We are making ultra low power device, which has function to read change of state on pin. For better understanding please refer the attached photo. Well, in Case 1 we get pulse on the pin as wheel is rotating and it's fine to read. But the problem is ...
Hi,I have a weird issue !I am developing an application where i Use the M24C64-WDW6TP EEPROM.First I need to be sure, this eeprom have 8KB of memory, every page is 32B so it has 256 pages.is the page address = (page number - 1 )*page_size ?? for exam...
Hi allwe are using a custom PCB with the STHV800 IC on it, in the past we've used it primarily as a pulser IC, not yet to take the reading signal into account. Now that we want to take a look at the echo, we don't see the expected echo when comparing...
