Microchip Tech · EEPROM · SOIC-8

AT24CM02-SSHD-T from Microchip Tech, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No Connect pin, not internally connected to the device; Table 2-1 lists it as A3 on the 8-ball WLCSP.
2	NC	unconnected	No Connect pin, not internally connected to the device; Table 2-1 lists it as B4 on the 8-ball WLCSP.
3	A2	input	Device address input hard-wired to GND or VCC for multi-device selection (up to two devices on one bus); if left floating it is internally pulled down to GND, and Microchip recommends a known state with any pull-up of 10 kΩ or less.
4	GND	power_in	Ground reference for the power supply, which should be connected to the system ground.
5	SDA	bidirectional	Open-drain serial data input/output that must be pulled high with an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices.
6	SCL	input	Serial clock input: commands and input data on SDA are latched on the rising edge of SCL and output data is clocked out on the falling edge; it must be held high when the bus is idle or pulled high with a pull-up resistor.
7	WP	input	Write-protect input: connecting it to GND allows normal write operations, while connecting it to VCC inhibits all writes to the protected memory (full array); if left floating it is internally pulled down to GND and Microchip recommends a known state with any pull-up of 10 kΩ or less.
8	VCC	power_in	Device power supply pin; operation at invalid VCC voltages may produce spurious results and should not be attempted (part is rated 2.5V to 5.5V for this -SSHD ordering option).
