It operates from 1.7 V to 5.5 V, supports a 1 MHz clock rate, and delivers a 650 ns access time. The part comes in a 4-ball WLCSP measuring 0.85 x 0.85 mm, rated for -40°C to 85°C industrial temperature range. This is a non-volatile memory intended for parameter storage, calibration data, or small firmware patches in space-constrained embedded designs.
At 1 MHz I²C, the 650 ns access time is the time from the address match to the first data bit being available on the bus. The 5 ms write cycle time per word or page is typical for EEPROM — firmware must poll the acknowledge polling or insert a delay after each write.
