24AA64FT-I

Microchip Tech · Global Sourcing Parts · SOT-23-5

24AA64FT-I from Microchip Tech, in a SOT-23-5. 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	SCL	input	The SCL input synchronizes data transfer to and from the device on the 2-wire serial bus.
2	VSS	power_in	Ground reference for the device.
3	SDA	bidirectional	Open-drain serial address/data I/O that requires a pull-up resistor to VCC (typically 10 kΩ for 100 kHz, 2 kΩ for 400 kHz); SDA may change only while SCL is low except for Start/Stop conditions.
4	VCC	power_in	Power supply, +1.7V to 5.5V for the 24AA64F.
5	WP	input	Must be tied to VSS or VCC: tied to VSS enables write operations, while tied to VCC inhibits writes to the upper 1/4 of the array (1800h-1FFFh) with reads unaffected.
