24AA04HT-I

Microchip Tech · EEPROM · SOT-23-5

24AA04HT-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, with Schmitt trigger inputs for noise suppression and 100 kHz, 400 kHz and 1 MHz clock compatibility.
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 and 1 MHz), and may change only while SCL is low except for Start/Stop conditions.
4 VCC power_in Power supply pin; the 24AA04H operates from 1.7V to 5.5V according to the device selection table.
5 WP input Write-protect input that must be tied to VSS (normal read/write of 000h-1FFh) or VCC (write operations inhibited for the upper half, 100h-1FFh; reads unaffected).
