Product details

2 Kbit I2C EEPROM with industrial temperature range

The Microchip 24LC024-E/SN is a 2 Kbit serial EEPROM with an I2C interface, organized as 256 x 8 bits. The 125°C ceiling covers most engine-compartment and exhaust-adjacent applications that a standard 85°C EEPROM cannot handle.

If you are sourcing it for a long-life program, the active status means the supply channel remains open through normal distribution.

Package and mounting — 8-SOIC, Tube delivery

The listed shipping medium is Tube, which is typical for engineering samples or small-batch production. If you need Tape & Reel for automated assembly, check the 24LC024T-I/SN variant or the 24LC025T-I/ST peer — both are reel-delivered.

Frequently asked questions

What is the I2C clock frequency of 24LC024-E/SN?

The 24LC024-E/SN supports a 400 kHz I2C clock frequency, which is standard I2C Fast Mode. The bus master and pull-up resistors must be sized for this speed to avoid timing violations.

What is a direct replacement for 24LC024-E/SN?

The closest functional peer is the 24LC025T-I/ST, which also offers 2 Kbit density, 900 ns access, 400 kHz I2C, and a 256 x 8 organization. The key difference is the package: the 24LC025T-I/ST comes in an 8-TSSOP package (Tape & Reel) versus the 8-SOIC (Tube) of the 24LC024-E/SN. If you need the full 125°C rating, the 24LC024-E/SN is the correct choice.
