AT24CS32-STUM-T from Microchip, in a SOT-23-5. Symbol and footprint are the ones used on Adom board designs (KiCad official libraries); the 3D model is KiCad's TSOT-23-5 library model, checked against Microchip's NMB package drawing. Pin functions are extracted from the manufacturer datasheet with page references.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SCL | input | Serial Clock: clocks data into and out of the device; data on SDA is latched on the rising edge of SCL and clocked out on the falling edge. Force SCL high when the bus is idle or pull it high with an external resistor. [datasheet p.5] |
| 2 | GND | power_in | Ground: the ground reference for the power supply; connect to the system ground. [datasheet p.5] |
| 3 | SDA | bidirectional | Serial Data: open-drain bidirectional input/output for data transfer; pull high with an external resistor not exceeding 10 kΩ; may be wire-ORed with other open-drain or open-collector pins on the bus. [datasheet p.5] |
| 4 | VCC | power_in | Device Power Supply [datasheet p.6]; VCC = 1.7 V to 5.5 V. [datasheet p.1] |
| 5 | WP | input | Write-Protect: connected to GND allows normal write operations; connected directly to VCC inhibits all write operations to the protected memory. Internally pulled down to GND if left floating; tie it to a known state (pull-up of 10 kΩ or less). [datasheet p.5] |
