Overview
The M95160-DRDW3TP/K is an automotive-grade 16-Kbit serial EEPROM device produced by STMicroelectronics. It operates up to 145 °C and is compliant with the AEC-Q100 grade 0 standard, ensuring a very high level of reliability. The device is accessed through a simple serial SPI compatible interface that can run up to 20 MHz. The memory array is based on advanced true EEPROM technology, organized as 64 pages of 32 bytes each, with an embedded Error Correction Code logic to enhance data integrity. Additionally, it features an Identification Page for storing sensitive application parameters that can be permanently locked in read-only mode.
