AT24C08N SMD IC EEPROM SOP8 ATMEL 24C08 AT24C08N

Product Overview:

A surface-mount and through-hole, low-power non-volatile serial EEPROM memory integrated circuit family designed for reliable data retention in compact digital systems. Utilizing an industry-standard two-wire serial interface, it allows microcontrollers to store and retrieve system configurations, calibration parameters, and operational logs with minimal I/O pins. The chip incorporates onboard noise suppression features to safeguard data transfers in busy electrical environments.

Core Specifications:

Manufacturer: HGSEMI (HuaGuan Semiconductor / 华冠半导体)

Package Type: Available in standard 8-pin DIP8, SOP8, TSSOP8, and SOT23-5 configurations

Function: Two-Wire Serial EEPROM (Electrically Erasable Programmable Read-Only Memory)

Input Channels: 1 Bidirectional Serial Data pin (SDA)

Control Interface: I2C-compatible Two-Wire Serial Interface consisting of Serial Clock (SCL), Write Protect (WP), and hardware device address inputs (A0, A1, A2)

Features

• Flexible Memory Densities: The family scales from 2K bits up to 16K bits of structured storage, organized as AT24C02 (256 x 8), AT24C04 (512 x 8), AT24C08 (1024 x 8), and AT24C16 (2048 x 8).

• Wide Operating Voltage Window: Operates reliably across low-power and standard power rails spanning from 1.7V up to 5.5V.

• High-Speed Bus Compatibility: Supports bidirectional data transfer protocol speeds up to 1 MHz when running at 5V, and 400 kHz under lower voltage conditions (1.8V to 2.7V).

• Integrated Hardware Data Protection: Features a dedicated Write Protect (WP) pin that disables write operations when connected to VCC, preventing accidental data overwrites.

• Efficient Page-Write Capabilities: Supports partial page writes and full page writing modes, handling 8-byte blocks for the 2K variant and 16-byte blocks for the 4K, 8K, and 16K variants.

• Built-in Noise Suppression: Inputs feature an internal Schmitt Trigger and filtering networks to filter out high-frequency switching noise on the communication lines.

• High Structural Reliability: Engineered for heavy-duty operational lifespans, supporting 1 million write cycles with a data retention rating of up to 100 years.

Applications

• Smart Home Appliances: Stores user preference settings, timer configurations, and operational fault logs in smart refrigerators, washing machines, and air conditioners.

• Microcontroller Development Boards: Serves as the localized non-volatile storage companion for microcontrollers to keep boot setups and calibration data.

• Networking Equipment: Keeps MAC addresses, security credentials, and localized port mapping configurations inside routers and modems.

• Industrial Telemetry Modules: Logs calibration matrices, baseline sensor profiles, and runtime parameters for automated instrumentation machinery.

• Consumer Electronics: Manages channel memory tables, display brightness profiles, and regional settings inside televisions and monitor control boards.
