AT24LC08M

HGSEMI · EEPROM · SOP-8

AT24LC08M from HGSEMI, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device/page address input. On the AT24LC08 the A0 pin is a no-connect (only A2 is used for hardware device addressing) and should be tied to GND.
2 A1 input Device/page address input. On the AT24LC08 the A1 pin is a no-connect (only A2 is used for hardware device addressing) and should be tied to GND.
3 A2 input Hard-wired device address input. On the AT24LC08 only A2 is used for device addressing, allowing up to two 8K devices to share one I2C bus. Compared against bit A2 of the I2C control byte (1010 A2 P1 P0 R/W).
4 GND power_in Ground reference (0 V) for the device.
5 SDA bidirectional I2C serial data line. Bi-directional, open-drain output that requires an external pull-up resistor (typ. 1.3 kΩ at 2.5 V/5 V, 10 kΩ at 1.8 V per AC test conditions). Wire-ORable with other open-drain devices on the same bus.
6 SCL input I2C serial clock input. Data is clocked in on the positive edge and out on the negative edge. Supports up to 1 MHz at 5 V and 400 kHz at 1.8 V/2.5 V/2.7 V.
7 WP input Write Protect input. Tie to GND for normal read/write operations. When tied to VCC the entire 8K array is write-protected in hardware.
8 VCC power_in Power supply input, 1.7 V to 5.5 V. Typ. supply current 0.4 mA read / 2.0 mA write at 5 V, 100 kHz; standby current 2 µA max.
