Applications

1. Consumer Electronics

Smart Home Appliances: Stores user settings, configuration parameters (e.g., temperature, mode), and operation records.

TVs/Monitors: Stores EDID data such as resolution, color parameters, and user-defined modes.

Audio Devices: Stores equalizer settings, preset radio stations, volume levels, etc.

IoT Devices: Stores device-unique IDs, network configuration parameters, and sensor calibration data.

2. Communication andamp; Networking Equipment

Routers, Switches, Modems: Stores critical data such as MAC addresses, default configurations, and production debugging information.

Baseband Modules: Stores module configuration parameters and identification information.

3. Industrial andamp; Automotive Electronics

Industrial Control: Stores device calibration data, production dates, serial numbers, and maintenance logs.

Automotive Electronics: Used in infotainment systems, dashboards, and body control modules (BCMs) to store non-critical configuration data. Its industrial temperature range (-40anddeg;C to +85anddeg;C) meets most automotive and industrial requirements.

4. Computer andamp; Peripheral Devices

Printer Cartridges/Toners: A classic applicationandmdash;stores ink levels, serial numbers, and usage dates to prevent counterfeiting.

Motherboards (BIOS): Stores hardware configuration information.

RAID Cards: Stores configuration data.

Memory Modules: Stores SPD (Serial Presence Detect) information such as timings, voltage, and manufacturer details.

5. Medical Equipment

Portable Medical Devices: Stores device calibration data, user preferences, and usage records (note: medical certification requires system-level consideration).

Description

The AT24C32D provides 32,768 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 4,096 words of 8 bits each. The deviceandrsquo;s cascading feature allows up to eight devices to share a common 2‑wire bus. The device is optimized for use in many industrial and commercial applications where low‑power and low‑voltage operation are essential. The devices are available in space‑saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-pad XDFN, 5-lead SOT23 and 8 ball VFBGA packages. All packages operate from 1.7V to 5.5V.
