Description
Description
The M24C32-A125 is a 32-Kbit serial EEPROM automotive grade device operating up to 125 °C. The M24C32A125 is pliant with the very high level of reliability defined by the automotive standard AEC-Q100 grade 1. The device is accessed by a simple serial I2C patible interface running up to 1 MHz. The memory array is based on advanced true EEPROM technology (electrically erasable programmable memory). The M24C32-A125 is byte-alterable memories (4096 K × 8 bits) organized as 128 pages of 32 byte in which the data integrity is significantly improved with an embedded error correction code logic. The M24C32-A125 offers an additional identification page (32 byte) 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.
