Descripción general

Description

CAT24C03YI-G is a 4-kbit (512 × 8) I2C serial EEPROM from Catalyst (CAT) in an 8-pin package. It provides non-volatile storage for microcontroller data, with A0–A2 address pins to select on-bus devices and a WP (write-protect) pin to guard against writes. The device supports standard-mode and fast-mode I2C (up to 400 kHz). Memory addressing uses a 9-bit address: the high bit(s) come from A0–A2 in the device address, while the low bits are sent as a memory address byte. Typical write cycles are a few milliseconds, and the device supports page writes. Applications include small configuration data, calibration tables, and logs in embedded systems. The YI-G suffix denotes a RoHS-compliant, lead-free package. Operating voltage is typically 1.8–5.5 V.

Features

Concise features of CAT24C03YI-G:
- 3 Kbit (384-byte) I2C Serial EEPROM
- I2C two-wire interface (standard/fast mode up to 400 kHz)
- 8-pin package, RoHS-compliant (G)
- Supply voltage: 1.8 V to 5.5 V
- Page size: 8 bytes; supports page write (up to 8 bytes per operation)
- Random and sequential read operations
- Write cycle time (tWR) typically up to 5 ms
- Endurance: ~1,000,000 write cycles
- Data retention: long-term (typical many years)
- Hardware write-protect (WP) pin
- Operating temperature: industrial range (-40°C to +125°C)
- Suitable for general purpose EEPROM needs with low power consumption

Package

8-pin Small Outline Integrated Circuit package (SOIC-8), i.e., an 8-pin SOP plastic package. RoHS-compliant (lead-free).

Pinout

- Pin count: 8 pins (DIP-8/SOIC-8).
- Function: CAT24C03YI-G is an I2C serial EEPROM (non-volatile memory) with 8 pins: VCC, GND, SDA, SCL, A0, A1, A2 (address pins), and WP (write protect). Uses I2C bus for read/write operations and allows device addressing via A0–A2 and WP controls.

Manufacturer

- Manufacturer: Catalyst Semiconductor, Inc. (the CAT prefix is their brand). The CAT24C03YI-G is now part of ON Semiconductor’s portfolio after the Catalyst acquisition.
- Company type: A semiconductor company that designs and manufactures memory and other integrated circuits (EEPROMs, etc.). It is now part of ON Semiconductor.

Application

- 256-byte I2C EEPROM (2 Kb)
- Non-volatile storage for microcontrollers/SoCs
- Store configuration, calibration data, device IDs and serial numbers
- Small data logs, status flags, and event counters
- I2C memory expansion for embedded systems
- Boot/config data and parameter storage in consumer electronics, automotive and industrial equipment

Equivalent

Equivalent 2Kbit I2C serial EEPROMs (drop-in replacements) include:
- AT24C02/AT24C02C/D (Atmel/Microchip)
- 24LC02B / 24AA02E48 (Microchip)
- M24C02-W (STMicroelectronics)
These have the same I2C interface and similar memory size; verify page size, addressing, and package/pinout for exact compatibility.
