Description
- What it is: CAT24C03YI-G is a 3-kilobit I2C serial EEPROM (nonvolatile memory) used for small data storage in embedded systems.
- Capacity and organization: about 384 bytes of storage, accessible in bytes; addressable via the I2C protocol.
- Interface: 2-wire I2C bus (standard-mode up to 100 kHz; fast-mode up to 400 kHz in many designs).
- Addressing: device address includes fixed code plus hardware address pins (A0–A2) to allow multiple devices on the bus.
- Page writes and timing: supports page write (a defined page size) to improve write efficiency; typical write cycle time is a few milliseconds.
- Power and environment: designed for low-power operation with a broad supply range (commonly ~2.7–5.5 V; variants exist for wider ranges); RoHS-compliant packaging.
- Endurance and retention: nonvolatile storage with high write-cycle endurance and long data retention.
- Applications: parameter storage, calibration data, small data logging, and microcontroller backup data.
- For exact electrical specs (voltage, timing, page size, temperature range) consult the CAT24C03YI-G datasheet.
