24AA64T-E

Microchip Tech · EEPROM · SOT-23-5

24AA64T-E 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 Serial clock input that synchronizes data transfer to and from the device.
2 VSS power_in Ground.
3 SDA bidirectional Open-drain serial address/data I/O that needs a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz and 1 MHz).
4 VCC power_in Power supply; the 24AA64 operates from 1.7V to 5.5V.
5 WP input Write-protect input that must be tied to VSS (writes enabled) or VCC (writes inhibited, reads unaffected).
