We are looking to replace our use of M24M02-DR with M24M02E-F as it is available as TSSOP (the smaller CSP would also be useful but it seems no distributor is touching that at the moment) and cheaper (as I guess ST are promoting the replacement of th...

Is there any technical data regarding when the FIFO becomes functional after power up? I have noticed I2C comms and registers can be accessed quite quickly but if the FIFO is initialised too early (e.g. going into FIFO mode), it never starts storing ...

LIS2DE12 (or those similar in range). Reading FIFO I2C. Questions:1) I2C multiple byte read auto-increment. In order to continually read the FIFO with reg address auto incrementing from 0x28 to 0x2D then automatically wrapping around back to 0x28 aga...

Thank you.

Thank you for pointing out the settling time. Using the SPI bus in my application is impossible; I do not have the pins. I wish to know if the data in and out pins can be tied together.

Thank you, Eleon. Sorry, it looks like this was due to a brief but large spike on the supply, resetting the accelerometer. No problem with the accelerometer at all. Thank you for your help.

Niccolo, thanks ever so much for thinking hard about this for me. (Another limitation is, though, that I have a very poorly specified system clock (not crystal) so I cannot do any accurate timing of when to poll/read data.) Clearing the BDU bit is in...

M24M02E-F vs M24M02-DR

Can m95p32 serial data in and out be tied together to work with I2C bus? Is there a power up settling time?
