Overview
Description
- Memory: 512 × 8 (non-volatile storage for configuration, parameters, calibration, etc.).
- Interface: I2C two‑wire bus (slave device). Uses the 1010 device code with A0–A2 pins for up to 8 devices on the same bus.
- Features: random and sequential reads; page write (typically 8 bytes per page); WP pin for write protection.
- Durability: high write endurance (≈1,000,000 write cycles) and long data retention.
- Package: 8‑pin device; RoHS-compliant (suffix “G”/related variant).
- Typical use: microcontroller parameter storage, small data logging, and non-volatile configuration memory.
- Operating notes: standard I2C speed (and fast/normal modes per device capability); suitable for low- to mid-speed I2C applications.
If you need exact electrical specs, timing, voltage range, or temperature range for your particular variant, check the datasheet for CAT24C04YI-G.
Equivalent
- STMicroelectronics: M24C04-W
- Microchip: 24LC04B and 24AA04E (also MCP24AA04)
- Rohm: BR24C04F
Note: any other vendor’s 4Kbit I2C EEPROM with identical pinout, voltage range, and timing can be a direct substitute.
Features
- 4-kbit serial I2C EEPROM (512 × 8)
- I2C two-wire interface with standard-mode and fast-mode operation
- Hardware addressing via A0–A2 pins (up to 8 devices on a bus; address range 0x50–0x57 typical)
- Write-protect (WP) input for memory protection
- Page write capability with auto-increment of the internal address (typical page size ~16 bytes)
- Random read and sequential read support
- Endurance: ~1,000,000 write cycles; Data retention typically around decades
- Low-power operation with standby/power-down modes
- Operating temperature: industrial range (typical -40°C to +85°C)
- Voltage supply: commonly 2.7–5.5 V (I/O compatible within that range)
- RoHS-compliant, lead-free package (G suffix) in 8-pin package variants
Note: Always verify exact electrical specs (voltage range, page size, timing) from the specific datasheet revision for CAT24C04YI-G.
Pinout
- Function: 4-kbit I2C serial EEPROM (512 bytes of nonvolatile memory) with I2C interface. Uses A0–A2 pins for device address and a WP pin for write protection. Typical pinout: 1 A0, 2 A1, 3 A2, 4 GND, 5 SDA, 6 SCL, 7 WP, 8 VCC.
Manufacturer
- What kind of company: A semiconductor company that designs and manufactures integrated circuits, including memory devices like serial EEPROMs; it has since been acquired and is now part of ON Semiconductor.
Application
- Microcontroller configuration and calibration data
- Device IDs, serial numbers, lot codes, and manufacturing data
- Settings and user preferences for consumer electronics
- Security keys and access control data
- Automotive and industrial control parameters and fault codes
- Sensor/meter calibration constants and offsets
- Instrumentation and medical devices for non‑volatile parameters
It’s ideal where a tiny, low‑power memory preserves critical data between power cycles.
