M950x0 M950x0-W M950x0-R 4 Kbit, 2 Kbit and 1 Kbit serial SPI bus EEPROM with high-speed clock
The M950x0 family includes the M95040 (4 Kbit), M95020 (2 Kbit), and M95010 (1 Kbit) electrically erasable programmable memory devices. These devices are accessed via a high-speed SPI-compatible bus interface and support single supply voltages ranging from 1.8 V to 5.5 V depending on the specific model suffix.
Key features include a maximum clock rate of 10 MHz, a write time of 5 ms, and more than 1 million write cycles with over 40 years of data retention. The devices offer enhanced ESD protection and support for byte and page write operations up to 16 bytes. They are available in RoHS-compliant and Halogen-free packages, including SO8, TSSOP8, and UFDFPN8.
