Product details

4Kbit I2C EEPROM in 8-TSSOP — industrial temp, wide supply

The STMicroelectronics M24C04-WDW6TP is a 4Kbit serial EEPROM with an I2C interface, organized as 512 x 8 bits. The 900 ns access time and 400 kHz clock rate suit typical microcontroller I2C peripherals for parameter storage, calibration data, and device configuration in outdoor telecom, factory automation, and engine-bay applications.

That means STMicroelectronics is not actively promoting it for new projects, and the production window is finite. For existing BOM lines, secure your last-time-buy quantities or qualify a pin-compatible successor. The base product number M24C04 family includes multiple variants; verify the exact replacement with ST's current product selector or your distributor's cross-reference tool.

Supply range and I2C bus compatibility

The 2.5V to 5.5V supply means this EEPROM works directly on 3.3V and 5V buses without a level shifter, as long as the I2C pull-up resistors are sized for the rail voltage. The 400 kHz clock is standard fast-mode I2C; most MCU I2C peripherals support it natively.

Housed in an 8-TSSOP (4.40 mm width) package, surface-mount.

Frequently asked questions

Is M24C04-WDW6TP obsolete or NRND?

It is not yet fully discontinued, but STMicroelectronics is phasing it out. Plan a last-time-buy or qualify a replacement now.

Does M24C04-WDW6TP work with 5V logic?

Yes. The supply voltage range is 2.5V to 5.5V, so it operates directly on a 5V rail. The I2C interface is 5V-tolerant at the bus pins when pull-ups are referenced to 5V.

Can I use M24C04-WDW6TP with 3.3V?

Yes. The 2.5V minimum supply covers 3.3V operation. The I2C bus runs at 400 kHz with 3.3V pull-ups; the device is specified across the full 2.5V-5.5V range.

What is the difference between M24C04-WDW6TP and M24C04-WDW6T?

The difference is in the packaging and shipping medium: the 'P' suffix typically indicates Tape & Reel packaging, while the non-P variant may ship in a different format. The silicon and electrical specs (4Kbit, I2C, 400 kHz, 2.5V-5.5V, -40°C to 85°C) are identical. Verify the exact orderable part number against your BOM.
