AT24C04D-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 address input. On the 4K device (AT24C04) the A0 pin is a no-connect - it is not used for device addressing; the third address bit is used internally as a memory page-address bit. Kept as an input pin on the package for pin-compatibility with the 2K/8K/16K family. |
| 2 | A1 | input | Device address input. On the 4K device, A1 (together with A2) is a hard-wired device-select input that must match the corresponding bit of the I2C device address transmitted by the master. Tie to VCC or GND to set the chip's slave address. |
| 3 | A2 | input | Device address input. On the 4K device, A2 (together with A1) is a hard-wired device-select input that must match the corresponding bit of the I2C device address transmitted by the master. Tie to VCC or GND to set the chip's slave address. |
| 4 | GND | power_in | Ground reference (0 V) for the device supply and all logic-level I/O. |
| 5 | SDA | bidirectional | I2C serial data line. Bidirectional, open-drain output that must be pulled high with an external resistor to VCC; may be wire-ORed with other open-drain/open-collector devices on the bus. Carries device address, word address, and data during read and write transactions. |
| 6 | SCL | input | I2C serial clock input. Positive edges clock data into the EEPROM; negative edges clock data out. Schmitt-triggered and filtered for noise suppression. Supports up to 1 MHz at VCC ≥ 2.5V and up to 400 kHz at 1.7V. |
| 7 | WP | input | Write Protect input for hardware data protection. When tied to GND (or left in the normal-write state) allows normal read/write operations to the full array; when tied to VCC the entire array is write-protected (writes are ignored). Reads are unaffected in either state. |
| 8 | VCC | power_in | Positive supply input. Operating range 1.7 V to 5.5 V. Typical read current 0.14 mA and write current 0.28 mA at 5 V / 400 kHz; standby current ~0.03 µA. Decouple locally with a 0.1 µF ceramic capacitor to GND. |
