24AA16T-I

Microchip · EEPROM · SOT-23-5

24AA16T-I from Microchip, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 unconnected Not connected internally on the 24XX16. May be left floating or tied to VSS or VCC. Legacy address pin retained for pin compatibility with smaller 24XX family devices.
2 A1 unconnected Not connected internally on the 24XX16. May be left floating or tied to VSS or VCC. Legacy address pin retained for pin compatibility with smaller 24XX family devices.
3 A2 unconnected Not connected internally on the 24XX16. May be left floating or tied to VSS or VCC. Legacy address pin retained for pin compatibility with smaller 24XX family devices.
4 VSS power_in Device ground reference (0 V).
5 SDA bidirectional Bidirectional Serial Address/Data I/O. Open-drain output requires an external pull-up resistor to VCC (typical 10 kOhm at 100 kHz, 2 kOhm at 400 kHz). Schmitt-triggered input with 50 ns spike suppression.
6 SCL input Serial Clock input used to synchronize data transfer to and from the device. Schmitt-triggered input; supports 100 kHz and 400 kHz clock (400 kHz requires VCC >= 2.5V on 24AA16).
7 WP input Write-Protect input. Must be connected to either VSS or VCC. Tie to VSS to enable normal read/write operation over the entire array (000-7FF). Tie to VCC to inhibit all write operations (array is write-protected); reads are unaffected.
8 VCC power_in Positive supply voltage. Operating range +1.7V to +5.5V for 24AA16 (2.5V to 5.5V for 24LC16B). Absolute maximum 6.5V.
