Overview

Description

Introduction to 24LC1026-E/SN
- A high-density I2C serial EEPROM from Microchip: 1 Mbit total storage, organized as 128 Kbytes (128K x 8).
- Interface: 2-wire I2C bus (SCL, SDA) with standard/fast modes up to 400 kHz.
- Memory organization: uses a two-byte word address for memory access; A0–A2 address pins allow multiple devices on the same bus; WP pin provides write protection.
- Operation: supports random and sequential reads; page write up to large page size (typical 128 bytes); write cycle about a few milliseconds.
- Endurance and retention: ~1,000,000 write cycles; data retention ~100 years.
- Package/grade: 8-pin package; -E denotes extended temperature (industrial) grade; -SN indicates RoHS-compliant packaging option.
- Typical uses: configuration data, calibration tables, data logging, or any nonvolatile data storage for embedded systems.
Note: Always check the latest datasheet for exact electrical characteristics, timing, and packaging details.
