24AA01T-I

Microchip Tech · EEPROM · SOT-23-5

24AA01T-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 is used to synchronize the data transfer to and from the device.
2	VSS	power_in	Ground reference for the device; WP must be tied to VSS for normal read/write access to the full memory.
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), changing only while SCL is low for data transfer.
4	VCC	power_in	Power supply, +1.7V to 5.5V for the 24AA01.
5	WP	input	Write-protect input that must be tied to VSS (memory read/write enabled, 00-7F) or VCC (all write operations inhibited, read operations unaffected).
