# AT24C16C-SSHM-T-TUDI

**Tudi** · EEPROM · SOP-8

AT24C16C-SSHM-T-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/page address input A0. Hard-wired address bit on 2K devices; on the 16K variant this pin is a NO CONNECT internally since all three A-bits are used for memory page addressing. Tie to VCC or GND (per datasheet Device Addressing section). |
| 2 | A1 | input | Device/page address input A1. See A0 notes - on the 16K device this pin is a no-connect internally. |
| 3 | A2 | input | Device/page address input A2. See A0 notes - on the 16K device this pin is a no-connect internally. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | SDA | bidirectional | I2C serial data. Bi-directional, open-drain output; requires an external pull-up resistor to VCC and can be wire-OR'd with other open-drain devices on the bus. |
| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. |
| 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. |
| 8 | VCC | power_in | Positive supply voltage, 1.7 V to 5.5 V operating range (AT24C16C variant rated to 3.6 V compatible). Bypass with a 0.1 uF ceramic capacitor close to the pin. |
