# AT24C04D-STUM-T

**Microchip Tech** · EEPROM · SOT-23-5

AT24C04D-STUM-T from Microchip Tech, in a SOT-23-5. 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: open-drain I2C clock input for timing and data flow control; latches command and input data on rising edge, clocks output data on falling edge. |
| 2 | GND | power_in | Ground: the ground reference for the power supply. |
| 3 | SDA | bidirectional | Serial Data: open-drain bidirectional I2C data input/output requiring external pull-up resistor not exceeding 10kΩ; must be wire-ORed capable for multi-master operation. |
| 4 | WP | input | Write Protect: control input for hardware data protection; connect to GND for normal write operations or to VCC to inhibit all write operations to the memory array. |
| 5 | VCC | power_in | Device Power Supply: positive supply voltage input; operating range 1.7V to 3.6V; requires monotonic rise from GND with slew rate not exceeding 0.1V/μs. |
