AT24C32D-SSHM-T Pin Configuration
AT24C32D-SSHM-T Pinout
Package: 8-Lead SOIC
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | A0 | I | Device Address Input |
| 2 | A1 | I | Device Address Input |
| 3 | A2 | I | Device Address Input |
| 4 | GND | P | Ground |
| 5 | SDA | I/O | Serial Data |
| 6 | SCL | I | Serial Clock |
| 7 | WP | I | Write-Protect |
| 8 | VCC | P | Device Power Supply |
Notes
- A0, A1, A2, WP pins: Internally pulled down to GND when not driven. Microchip recommends connecting these pins to a known state whenever possible. Pull-down disengages once pin voltage exceeds ~0.5 × VCC.
- SDA/SCL: I²C interface pins (open-drain outputs typical for I²C applications).
