CAT24C16WI-GT3-TUDI from Tudi, in a SOP-8. 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 | input | Device address input. On the 16K device this pin is not used for device addressing (the three address bits are consumed as memory page-address bits) and is marked 'no connect' per the Device Addressing section, but it is a Schmitt-trigger address input on the smaller 2K/4K/8K family variants. Tie to GND if unused. |
| 2 | A1 | input | Device address input. On the 16K device this pin is not used for device addressing (bits are used for internal memory page addressing) and is marked 'no connect', but the pin is present on the package. Tie to GND if unused. |
| 3 | A2 | input | Device address input. On the 16K device this pin is not used for device addressing (bits are used for internal memory page addressing) and is marked 'no connect', but the pin is present on the package. Tie to GND if unused. |
| 4 | GND | power_in | Ground reference for the device. Connect to system ground (0 V). |
| 5 | SDA | bidirectional | I2C serial data line. Bi-directional, open-drain output; requires an external pull-up resistor to VCC (datasheet AC test uses RL = 1.3 kΩ). May be wire-ORed with other open-drain / open-collector devices. Schmitt-trigger, filtered input for noise suppression. |
| 6 | SCL | input | I2C serial clock input. Data is clocked into the EEPROM on the positive edge and out of the EEPROM on the negative edge. Supports up to 400 kHz at VCC 1.7-2.5 V and up to 1 MHz at VCC 2.5-5.5 V. Requires an external pull-up resistor to VCC. |
| 7 | WP | input | Write Protect input. Tie to GND for normal read/write operation. Tie to VCC to enable hardware write protection of the full memory array. Should not be left floating. |
| 8 | VCC | power_in | Positive supply input. Operating range 1.7 V to 5.5 V (VCC1); recommended decoupling with a 0.1 µF ceramic capacitor to GND close to the pin. ICC typical: 0.14 mA read / 0.28 mA write @ 5.0 V, 400 kHz. |
