M24512-DRDW8TP/K

M24512-DRDW8TP/K is a 512-Kbit serial I²C bus EEPROM (electrically erasable programmable memory) up to 105°C. It is compliant with the level of reliability defined by the AEC-Q100 grade 2. The device is accessed by a simple serial I2C compatible interface running up to 1MHz. The memory array is based on advanced true EEPROM technology. It is a byte-alterable memory (64K × 8 bits) organized as 512 pages of 128 bytes in which the data integrity is significantly improved with an embedded Error Correction Code logic. It offers an additional Identification Page (128bytes) in which the ST device identification can be read. This page can also be used to store sensitive application parameters which can be later permanently locked in read-only mode.
