Atmel AT24C64 I2C Serial EEPROM - 8 pin DIP
£2.39
Description
The AT24C64 provides 8192 bytes of EEPROM that can be connected easily to most microcontrollers using I2C.
Multiple AT24C64 can be used by assigning a different address via Pins A0, A1 and A2 pins - you may address a single device by the unique address number of the device using the I2C bus.
The pinout is as follows:
- A0: Address bit 0
- A1: Address bit 1
- A2: Address bit 2
- GND: Ground
- SDA: Serial Data
- SCL: Serial Clock Input
- WP: Write Protect
- VCC: Positive Voltage (between 2.7V and 5.5V)
The Write Protect pin allows you to protect the memory from changes - if this pin is low (0V) then all writes are allowed. If the pin is high (5V) the write is ignored.
