24C02S

XBLW 24C02S XBLW · EEPROM · SOT23-5

24C02S from XBLW 24C02S XBLW, in a SOT23-5. 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 SCL input Serial clock input for the 2-wire (I2C-compatible) bus. Data on SDA is latched into the EEPROM on the rising edge and clocked out on the falling edge. Requires an external pull-up resistor to VCC; supports 400 kHz at 1.8 V and up to 1 MHz at 2.5-5 V.
2 GND power_in Ground reference (0 V) for supply and signals.
3 SDA bidirectional Serial data line for the 2-wire (I2C-compatible) bus. Bidirectional, open-drain output that can be wire-OR'd with other open-drain devices; requires an external pull-up resistor to VCC.
4 VCC power_in Positive power supply, 1.8 V to 5.5 V. Absolute maximum is 8 V; decouple locally with a bypass capacitor to GND.
5 WP input Write Protect. When tied to VIH/VCC, all programming (write) operations are disabled; read operations are unaffected. When left unconnected or tied to VIL/GND, writes are enabled. If not driven, internally recognized as VIL; the datasheet recommends tying it to a known state through a 10 kΩ or smaller resistor to avoid capacitive-coupling glitches.
