AT24Cxxx group of I2C EEPROM with possibility to set address and write protect mode.

Digital Pin: 2, 3
Bus: TWI
Power Pin: GND, +5V

Analogue Pin: 4,5
Bus: TWI
Power Pin: GND, +5V

Configuration has one switch group (A0, A1, A2) and one switch WP with two state 0 (short cut between middle pin and pin signed 0) and 1 (short cut between middle pin and pin signed 1).

• A0 - address bit 0 (default set to 0)
• A1 - address bit 1 (default set to 0)
• A2 - address bit 2 (default set to 0)
• WP - write protect where 1 mean protected, and 0 mean unprotected (default set to 0)
