CAV24C256WE-GT3

onsemi · EEPROM · SOIC-8

CAV24C256WE-GT3 from onsemi, in a SOIC-8. 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 A0 input Device address input that selects one of up to eight devices on the bus, with an on-chip pull-down resistor.
2 A1 input Device address input that selects one of up to eight devices on the bus, with an on-chip pull-down resistor.
3 A2 input Device address input that selects one of up to eight devices on the bus, with an on-chip pull-down resistor.
4 VSS power_in Ground.
5 SDA bidirectional Serial data I/O that receives input data and transmits stored data, open drain in transmit mode.
6 SCL input Serial clock input that accepts the clock signal generated by the master.
7 WP input Write protect input that inhibits all write operations when pulled HIGH, with an on-chip pull-down resistor.
8 VCC power_in Power supply, 2.5 V to 5.5 V.
