Description

The Microchip Technology Inc. 24XX32A(1) is a 32-Kbit Electrically Erasable PROM (EEPROM). The device is organized as a single block of 4Kx8-bit memory with a two-wire serial interface. Its low-voltage design permits operation down to 1.7V, with standby and active currents of only 1µA and 1mA, respectively. The 24XX32A also has a page write capability for up to 32bytes of data. Functional address lines allow up to eight devices on the same bus for up to 256Kbits address space.

Applications

Data Storage & Configuration
  Microcontroller (McU) External Memory: Stores system parameters, calibration data, and
  user settings (e.g. Arduino, STM32).
  loT Devices: Saves Wi-Fi configurations, sensor data, and device lDs.
Consumer Electronics: Retains user preferences in TVs, set-top boxes, and printers.
  Industrial & Automotive Electronics
  Industrial Control Systems: Logs operational data and fault codes (industrial-grade -40'C to+85°C support).
  Automotive Electronics: Stores mileage and diagnostic info (wide 2.5V-5.5V voltage range).

Smart Hardware & Sensors
  Wearable Devices: Tracks user activity data (low power extends battery life)

  Sensor Modules: Buffers data to prevent loss during power outages (1 million write cycles).

Networking & Communication Devices

  Routers/Switches: Saves MAC addresses and firmware backups (l2C simplifies circuit design).
Other General Uses
  Replaces On-Chip Flash: Expands limited MCU storage (compact SOlC-8 package savesspace).
