Product details

16 Kbit I²C EEPROM — what this part is

The STMicroelectronics M24C16-WMN6TP is a 16 Kbit serial EEPROM organized as 2K x 8 bits, accessed over an I²C bus at up to 400 kHz. It is a non-volatile memory device for storing configuration parameters, calibration data, or small firmware tables in embedded systems. The 900 ns access time is typical for this density and bus speed, and the wide supply range of 2.5V to 5.5V lets it work across 3.3V and 5V logic domains without a level shifter.

NRND status — plan the replacement now

It is not yet discontinued, so existing production lines can still source it, but STMicroelectronics has flagged it for phase-out. For a new BOM or a long-running product, qualifying a pin-compatible replacement — such as the M24C16-WMN6T or a sibling in the same family — is the prudent move to avoid a future last-time-buy scramble. The 8-SOIC footprint is widely used, so alternate vendors (Microchip, Onsemi) offer drop-in equivalents with the same 2K x 8 I²C interface.

The write cycle time of 5 ms per word or page is typical for this class — budget it into the firmware's non-volatile write routine.

Frequently asked questions

What is the M24C16-WMN6TP memory size and interface?

It is a 16 Kbit EEPROM organized as 2K x 8 bits, accessed via an I²C serial interface running at up to 400 kHz.

Is M24C16-WMN6TP obsolete or discontinued?

Existing builds can still source it, but new designs should select a pin-compatible replacement.

Does M24C16-WMN6TP have a different package variant like TSSOP?

This specific variant is in an 8-SOIC package. The M24C16 family includes TSSOP-8 options (e.g., M24C16-WDW6TP), but the WMN6TP suffix denotes the SOIC footprint. Check the base product number M24C16 for alternate package codes.
