- Memory organization: 512 words x 8 bits (32 pages of 16 bytes)
- Interface: 2-wire serial I2C bus
- Clock frequency: 400 kHz maximum bus speed
- Operating voltage range: 1.8V to 5.5V
- Hardware write protection via dedicated WP pin
- Package: 8-lead JEDEC SOIC (150 mil body width)
- Surface-mount termination with intact gull-wing leads
Applications
- Storing board calibration constants, serial numbers, and configuration settings in microcontroller builds
- Replacing failed serial memory chips during industrial control board and PCB repair
- Retaining user preferences, runtime counters, or sensor calibration in Arduino and maker prototyping projects
Frequently Asked Questions
What is the memory capacity of the 24C04?
The 24C04 provides 4 Kbits (4,096 bits) of non-volatile storage organized as 512 bytes, arranged into 32 pages of 16 bytes each.
What communication protocol does this IC use?
It uses a standard 2-wire I2C-compatible serial interface requiring only serial data (SDA) and serial clock (SCL) lines, along with power and ground connections.
What condition is this pulled chip in?
This chip was pulled from decommissioned equipment and passed visual inspection with clean, intact leads. Function testing has not been performed, and it is covered by our satisfaction guarantee.
Four kilobits of solid-state recall ready to hold the calibration table or system profile your controller needs. Solder it down and give your firmware its memory back.
