Description
General part information
M95640-A145 Series
The M95640-A125 and M95640-A145 are 64-Kbit serial EEPROM Automotive grade devices operating up to 145°C. They are compliant with the very high level of reliability defined by the Automotive standard AEC-Q100 grade 0.
The devices are accessed by a simple serial SPI compatible interface running up to 20 MHz.
The memory array is based on advanced true EEPROM technology (Electrically Erasable PROgrammable Memory). The M95640-A125 and M95640-A145 are byte-alterable memories (8192 × 8 bits) organized as 256 pages of 32 byte in which the data integrity is significantly improved with an embedded Error Correction Code logic.
