24LC64FT-I

Microchip Tech · EEPROM · SOT-23-5

24LC64FT-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 Serial Clock input that synchronizes data transfer to and from the device.
2 VSS power_in Ground.
3 SDA bidirectional Serial Address/Data I/O, an open-drain bidirectional pin that needs a pull-up resistor to VCC (typical 10 kΩ for 100 kHz, 2 kΩ for 400 kHz).
4 VCC power_in Power supply, +1.7V to 5.5V per the pin table (2.5V to 5.5V for the 24LC64F per the device selection table).
5 WP input Write-Protect input that must be tied to VSS or VCC; at VSS writes are enabled, at VCC writes are inhibited for the upper 1/4 of the array (1800h-1FFFh).
