Eeprom m95080 Software driver

Kindly provide me with the software driver files of m95080 eeprom ic.

Using a m24c01-r EEPROM, I have had an event where an address that I have written to with a known value once, has had its contents modified to x"00".

Macros of EEPROM emulation return wrong answer

Hello,I currently work with an STM32L496ZG chip and the EEPROM emulation driver (download on https://www.st.com/en/embedded-software/x-cube-eeprom.html).In the "eeprom_emul.h" file, we have the next macro :#define PAGE_ADDRESS(__PAGE__) (uint32_t)(...

Resolved! M24M02 - read time longer than write time?

I am working with M24M02 and I measured that it takes 50% longer to read a page than to write a page. Is this normal that read time exceeds write time? NOTE: This question and answer originated from a customer support case which was handled by us. W...

Trouble with ST CHN P 24C32WP EEPROM

We have a programming problem for this ST CHN P 24C32WP K2A823 component that was provided to us. The reference component we use and know how to program is the ST CHN P 24C32WP K2A237. The only difference in marking on the IC is 823 instead of 237. W...

I can not read / write NFC tag (NfcV)

I am developing a mobile application for Android for reading and writing data on NFC. While working with the M24SR04 chip from ST, then everything worked. After the transition to the chip M24LR64ER (also from ST) - ceased.This can be done using other...

Want to know the memory roll over scenario in case of byte write in EEPROM M95M02-A125..

The EEPROM range for M95M02-A125 is from 0x00 to 0x3ffff. When a byte write is initiated at 0x40000, it overwrites the contents of the location 0x00. Is this the expected behavior? In data sheet the roll over for page write is mentioned, like the in...
