SparkFun Qwiic EEPROM Breakout Board (512Kbit) is designed to evaluate CAT24C512 IC and is a simple board with an option to add extra storage space. This simple breakout board comes with 512Kbit of storage and is compatible with any microcontroller that does not have EEPROM storage space, like the SAMD21. The Qwiic EEPROM offers three address jumpers allowing for up to eight EEPROMs on one bus. The on-board CAT24C512 IC is a 512Kb EEPROM flash memory, organized as 65,536 words of 8-bits each with a 128byte page write buffer. The IC features a 128byte page write buffer and supports the Standard (100kHz), Fast (400kHz), and Fast-Plus (1MHz) I2C protocol. The Qwiic EEPROM breakout board operates at 3.3V supply voltage, 1mA of reading current, and 1.8mA to 2.5mA of write current range. This breakout board features Qwicc connectors, write protection, and an I2C Address of (7-bit).
