- Maybe your project needs to store data, like a public-key, in non-volatile memory? Maybe you want to use multiple boards as configuration keys with different default settings for your project? The SparkFun Qwiic EEPROM Breakout is a simple and cost effective option to add some extra storage space to any project. With 512 kilo-bits (or 64 kilo-bytes) of storage, this product is great for any microcontroller that doesn't have any EEPROM storage space, like the SAMD21. You can use the Qwiic EEPROM for storing data like GPS waypoints and other user settings that need to be maintained between sketch uploads. The SparkFun Qwiic EEPROM has three address jumpers, allowing for up to eight EEPROMs on one bus. All communication is enacted exclusively via I2C, utilizing our handy Qwiic system (as the name implies). The on-board CAT24C512 IC is a 512Kb EEPROM flash memory, organized as 65,536 words of 8 bits each with a 128-byte page write buffer. An on board ECC (Error Correction Code) makes this EEPROM suitable for high reliability applications. Features: Power: 3.3V; CAT24C512 EEPROM: Supply Current: Read Current: 1mA, Write Current: 1.8mA - 2.5mA, Memory: 512-Kb (kilobit), Page Write Buffer: 128 bytes, Reliability: Endurance: 1,000,000 Program/Erase Cycles, Data Retention: 100 Years, Write Protection, I2C Address (7-bit):, 0x50 (Default), 0x51, 0x52, 0x53, 0x54, 0x55, 0x56, 0x57, 2x Qwiic Connectors Note: EEPROM board only. No cables or microcontroller included.
