M24C08-WMN6P

STMicroelectronics · EEPROM · SO-8

M24C08-WMN6P from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected Not connected. In the SO8/TSSOP8/PDIP8/UFDFPN8 8-lead M24C08, pin 1 is unused (reserved / no internal bond). May be left floating or tied to VSS.
2 NC unconnected Not connected. In the SO8/TSSOP8/PDIP8/UFDFPN8 8-lead M24C08, pin 2 is unused. May be left floating or tied to VSS.
3 E2 input Chip Enable address input. Sets the value of bit b3 of the I2C device select code (1010 E2 A9 A8 R/W), allowing up to two M24C08 devices to share the same I2C bus. Must be tied to VCC or VSS; if left floating it is read as 0.
4 VSS power_in Ground reference for VCC and all logic signals. 0 V.
5 SDA bidirectional I2C Serial Data input/output. Open-drain output - an external pull-up resistor from SDA to VCC is required (typical 1 kΩ-10 kΩ depending on bus capacitance and speed; see Figure 13 for Rbus vs. Cbus at 400 kHz).
6 SCL input I2C Serial Clock input. Strobes data available on SDA(in) and clocks out data on SDA(out). Supports 100 kHz standard-mode and 400 kHz fast-mode I2C.
7 WC input Write Control (write protect). When driven high, the entire memory array is protected: device select and address bytes are acknowledged but data bytes are NoAck'd and no write occurs. Write operations are enabled when WC is driven low or left floating (internal pull-down / read as 0).
8 VCC power_in Positive supply voltage. For the -W variant: 2.5 V to 5.5 V operating range. Decouple to VSS with a 10 nF-100 nF capacitor close to the package.
