24AA16HT-I

Microchip Tech · Pre-ordered Chips · SOT-23-5

24AA16HT-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 used to synchronize data transfer to and from the device.
2 VSS power_in Ground.
3 SDA bidirectional Serial Address/Data I/O; open-drain bidirectional pin that requires 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; 1.7V-5.5V for 24AA16H and 24FC16H, 2.5V-5.5V for 24LC16BH.
5 WP input Write-Protect input that must be tied to VSS (full memory read/write) or VCC (write operations inhibited for 400h-7FFh, reads unaffected).
