AT24C08C-PUM

Microchip Tech · EEPROM · DIP-8

AT24C08C-PUM from Microchip Tech, 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 NC unconnected No connect pin; the datasheet states pin 1 is a no connect and can be connected to ground.
2 A1/NC input Address input A1 on the 4K device, but on the AT24C08C it is a no connect and must be tied to ground, as the A0 and A1 pins are no connects on the 8K device.
3 A2 input Hard-wired address input A2 that must match its device address bit; on the 8K device it is the only hardware address input and two 8K devices may share one bus.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Bidirectional serial data pin that is open-drain driven and may be wire-ORed with other open-drain or open-collector devices.
6 SCL input Serial clock input: data is clocked into the device on the SCL positive edge and clocked out on the negative edge.
7 WP input Write Protect: connecting it to GND allows normal read/write operations, while connecting it to VCC enables write protection of the full array.
8 VCC power_in Power supply, specified from 1.7 V to 5.5 V over the recommended operating range.
