AT24C32D-SSHM-T Pinout

Package: 8-Lead SOIC

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.
• SDA/SCL: Standard I²C interface pins.
• WP: Write-protect pin; when high, write operations are disabled.
