Microchip Technology AT24CSWx Serial EEPROMs are designed to be I2C compatible (two-wire) with a security register and software write protection. These EEPROMs feature bidirectional data transfer protocol and filtered inputs for noise suppression. The AT24CSWx EEPROMs operate at a 1.7V to 3.6V voltage range, 1mA ultra-low active current, 0.8µA standby current, and -40°C to 85°C temperature range. The AT24CSW01X / AT24CSW02X EEPROMs provide 8-Byte page write mode and AT24CSW04X / AT24CSW08X EEPROMs offer 16-Byte page write mode with partial page writing. These EEPROMs are available in 5-lead SOT23 and 4-ball ultra-thin WLCSP packages.
