ST M95040 M95020 M95010 4Kbit 2Kbit 1Kbit Serial SPI Bus EEPROM With High Speed Clock handbook
The M95040, M95020, and M95010 are electrically erasable programmable memory (EEPROM) devices accessed via a high-speed SPI-compatible bus. The family includes 4 Kbit, 2 Kbit, and 1 Kbit variants, respectively, compatible with positive clock SPI modes. They feature a single supply voltage ranging from 1.8V to 5.5V depending on the specific model suffix, a 10MHz clock rate, and a 5ms write time. The devices support BYTE and PAGE WRITE operations (up to 16 Bytes) using a self-timed programming cycle.
