Overview
The M24256-DRMF3TG/K is a 256-Kbit serial EEPROM device manufactured by STMicroelectronics, designed for automotive applications. 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 can run up to 1 MHz. The memory array is based on advanced true EEPROM technology, organized as 512 pages of 64 bytes each, with an embedded Error Correction Code logic to enhance data integrity. Additionally, it includes an Identification Page for storing device identification and sensitive application parameters, which can be permanently locked in read-only mode.
