AT24C64N

HGSEMI · EEPROM · DIP-8

AT24C64N from HGSEMI, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input that is hard wired and must match the A0 bit of the device address word; up to eight devices can share one bus.
2 A1 input Device address input that is hard wired and must match the A1 bit of the device address word; up to eight devices can share one bus.
3 A2 input Device address input that is hard wired and must match the A2 bit of the device address word; up to eight devices can share one bus.
4 GND power_in Ground.
5 SDA bidirectional Bidirectional serial data pin with open-drain output that may be wire-ORed with other open-drain or open-collector devices and needs an external pull-up.
6 SCL input Serial clock input that clocks data into the EEPROM on the positive edge and out on the negative edge.
7 WP input Write protect input that allows normal read/write when connected to GND and protects the full array when connected to VCC.
8 VCC power_in Power supply, 1.8V to 5.5V operating range.
