how to establish a communication with M24c32-R?
I am trying to communicate M24C32-R with master but for some reason i could not able to !! It appears to me it might be hardware issue. I have connected E0,E1,E2 to ground , Vcc to 3.3V, WC to ground, I have pulled up SCL and SDA to 3.3V with 10K oh...
Hello, I would like some extra info relative to STG719 to add it to my design. The datasheet says Icc,max of 1uA for industrial temperature range. Could you give m a graph with the variation for Icc,max with temperature and Vcc? Thank you in advanced.
Find attached an example of a similar product. Figure 8 of page 9 of TS3A4742 chip.
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 ...
M24C08 NC pins
Hi,Because of my PCB design, the NC pins of M24C08 eeprom are connected to GND. Would this cause any problem ? Any advise ?
Part marking 2N6796FB
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.
