Description
M24512-DRE
The M24512-DRE is a 512-Kbit serial EEPROM device operating up to 105 °C. The
M24512-DRE 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 1 MHz.
The memory array is based on advanced true EEPROM technology (electrically erasable
programmable memory). The M24512-DRE is a byte-alterable memory (64 K × 8 bits)
organized as 512 pages of 128 bytes in which the data integrity is significantly improved
with an embedded Error Correction Code logic.
The M24512-DRE offers an additional Identification Page (128 bytes) 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.
