# TP24C02S5

**TECH PUBLIC** · EEPROM · SOT-23-5

TP24C02S5 from TECH PUBLIC, 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 input. Positive-edge clocks data in, negative-edge clocks data out. Schmitt-trigger filtered. Must be pulled high externally per I2C spec. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | SDA | bidirectional | Bidirectional serial data line. Open-drain output; requires an external pull-up resistor to Vcc (typ. 1.3k for 2.5-5.5V, 10k at 1.7V). Wire-OR capable with other open-drain devices. |
| 4 | Vcc | power_in | Supply voltage input, 1.7V to 5.5V. Read current 400 uA max, write current 1.6 mA max. |
| 5 | WCB | input | Write control input, active-low. Tie to GND to allow normal writes; tie to Vcc to inhibit all writes (hardware write-protect). Internally pulled down to GND when left floating. |

## CAD (KiCad official)

- Symbol: `TP24C02S5`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tp24c02s5-etched.step` / `tp24c02s5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tp24c02s5.step` / `tp24c02s5.glb` are the bare package body.
