The CAT24C32 is a 32-kb I2C serial EEPROM device internally organized as 4096 words of 8 bits each. It has a 32-byte page write cache and supports standard (100 kHz), fast (400 kHz), and ultra-fast (1 MHz) I2C protocols. External address pins make it possible to place up to eight CAT24C512 devices on the same bus.
Ultra-low power consumption design, standby power consumption is less than 1uA Provide 8192-bit serial EEP memory, composed of 1024 bytes, 16 bytes per page, 64 pages in total
