24AA024-I

Microchip Tech · Pre-ordered MCUs · SOIC-8

24AA024-I 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	A0	input	Address input A0 used for multiple-device operation; must be tied to VCC or VSS.
2	A1	input	Address input A1 used for multiple-device operation; must be tied to VCC or VSS.
3	A2	input	Address input A2 used for multiple-device operation; must be tied to VCC or VSS.
4	VSS	power_in	Ground.
5	SDA	bidirectional	Serial address/data I/O; open-drain, requires a pull-up resistor to VCC (typical 10 kΩ for 100 kHz and 2 kΩ for 400 kHz).
6	SCL	input	Serial clock input that synchronizes data transfer to and from the device.
7	WP	input	Hardware write-protect input on 24XX024; must be tied to VCC (protection enabled) or VSS (disabled), and is not internally connected on the 24XX025.
8	VCC	power_in	Power supply, 1.7V to 5.5V for 24AA024/24AA025 and 2.5V to 5.5V for 24LC024/24LC025.
