Overview

Description

CAT24C04YI-G is a 4-kilobit I2C serial EEPROM from Onsemi (Catalyst). It stores 512 bytes of data (512 x 8) organized as 32 pages of 16 bytes each. Access is via I2C two-wire, with A0–A2 pins selecting the memory block; the device address follows 1010 A2 A1 A0. It supports byte and 16-byte page writes, with typical 5 ms write cycles. Features include up to ~1,000,000 write cycles endurance and about 40-year data retention. Operating voltage is in the common I2C EEPROM range (roughly 1.8–5.5 V), and it typically covers a commercial temperature range (e.g., -40 to 85 °C). The “G” suffix denotes RoHS-compliant packaging. Suitable for small, nonvolatile storage for microcontrollers and embedded systems.

Features

Key features of CAT24C04YI-G (4‑Kbit I2C EEPROM):
- 4 Kbit serial EEPROM (512 × 8)
- I2C two-wire interface; standard 100 kHz and fast 400 kHz modes
- 7-bit device address: 1010 with A2–A0 pins (up to 8 devices on a bus)
- Random read and write; page write up to 8 bytes
- Write cycle time (tWC) max ≈ 5 ms
- Endurance ≈ 1,000,000 write cycles; data retention ≈ 40 years
- Operating voltage: 1.8–5.5 V
- WP pin for hardware write protection
- Low power operation; RoHS-compliant; available in 8-pin packages (e.g., SOIC, MSOP)

Package

8-pin plastic SOIC (Surface Mount Small-Outline) package; RoHS-compliant Pb-free variant.

Pinout

- Pin count: 8 pins.
- Function: 4-kilobit I2C serial EEPROM (non-volatile memory) with I2C interface (SDA, SCL). Has address pins A0–A2 to set the I2C address, a WP pin for write protection, plus Vcc and GND. Stores up to 512 bytes.

Manufacturer

CAT24C04YI-G is manufactured by Catalyst Semiconductor (brand CAT). Catalyst Semiconductor is a semiconductor company that designs and markets memory (EEPROM) and analog ICs. The company was acquired by ON Semiconductor in 2010, so today the product line is under ON Semiconductor, a large global semiconductor manufacturer.

Application

- Non-volatile parameter storage for microcontrollers (config, calibration, lookup tables)
- Device identification (serial numbers/IDs) and security keys
- Small data logging and event counters
- External EEPROM for firmware/config data in IoT, consumer electronics, automotive and industrial systems

Equivalent

CAT24C04YI-G is a 4-kbit I2C serial EEPROM. Equivalents include:
- AT24C04 (Atmel; now Microchip) and its variants (AT24C04A/B/C)
- Microchip 24AA04/24LC04B
- ST M24C04-W
- Xicor/Xicor X24C04 (Intersil)
These are generally 8-pin I2C EEPROMs with similar capacity and voltage ranges; verify exact addressing, package, and timing in datasheets.
