24FC04HT-I

Microchip Tech · EEPROM · SOT-23-5

24FC04HT-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, with Schmitt trigger input and up to 1 MHz clock compatibility for the 24FC04H.
2 VSS power_in Ground reference pin 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 and 1 MHz); SDA may change only while SCL is low except for Start and Stop conditions.
4 VCC power_in Power supply pin; the 24FC04H operates from 1.7V to 5.5V.
5 WP input Write-protect input that must be tied to VSS for normal read/write of the full array (000h-1FFh) or to VCC to inhibit writes to the upper half of the array (100h-1FFh) while reads are unaffected.
