Overview
The M24C16-DRMF3TG/K is an automotive-grade 16-Kbit serial EEPROM device produced by STMicroelectronics. This device operates up to 125 °C and is compliant with the high reliability standards defined by the automotive standard AEC-Q100 grade 1. It features a simple serial I²C compatible interface that runs up to 1 MHz. The memory array is based on advanced true EEPROM technology, organized as 128 pages of 16 bytes each, with an embedded error correction code logic to improve data integrity. Additionally, it includes an identification page for storing device identification and application-specific parameters, which can be permanently locked in read-only mode.
