Product details

NRND — plan your replacement now

The M24C01-WMN6P: This means STMicroelectronics is not actively promoting it for new projects. For existing BOM lines, this part remains available through independent distribution, but any new design should target a current-production I²C EEPROM from the same family or a direct cross.

The STMicroelectronics M24C01-WMN6P is a 1 Kbit serial EEPROM organized as 128 x 8 bits, accessed through an I²C interface at clock frequencies up to 400 kHz (Fast Mode). It is a non-volatile memory for storing small amounts of configuration data, calibration constants, device IDs, or fault logs in embedded systems. The 900 ns access time and 5 ms write cycle (word/page) are standard for this density class.

Package and footprint — 8-SOIC narrow

Surface-mount assembly with typical reflow profiles for MSL 1 parts applies. The tube shipping medium is fine for low-volume prototyping.

Frequently asked questions

Is M24C01-WMN6P obsolete?

This means STMicroelectronics may issue an EOL notice in the future. For existing production, the part is still available through independent distributors. For new designs, select a current-production I²C EEPROM from the M24C family or a compatible alternative.

What is the replacement for M24C01-WMN6P?

Within the same M24C family, a current-production part with the same I²C interface, 1 Kbit density, and 8-SOIC package would be the natural cross. Check the STMicroelectronics M24C01 series for active suffix variants (e.g., M24C01-WMN6T for tape-and-reel, or the newer M24C01-F series if available). For a pin-compatible second source from another manufacturer, the Microchip 24AA01/24LC01 series in 8-SOIC is a common alternative.

What is the memory size of M24C01-WMN6P?

The memory size is 1 Kbit, organized as 128 bytes x 8 bits. This is suitable for storing small configuration data, calibration values, or device parameters — not for firmware or large data logs.
