24LC16BT-E

Microchip Tech · EEPROM · SOT-23-5

24LC16BT-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 used to synchronize data transfer to and from the device.
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).
4 VCC power_in Power supply input; the 24LC16B operates from 2.5V to 5.5V.
5 WP input Write-protect input: tied to VSS enables normal read/write of the full memory, tied to VCC inhibits write operations while reads are unaffected.
