Bidirectional pin for serial knowledge transmission

The SCL enter is accustomed to positiveedge clock data into each and every EEPROM device and negativeedge clock data out of every single machine.SERIAL Facts (SDA): The SDA pin is bi-directional forserial knowledge transfer.

This pin is open-drain pushed and perhaps wire-ORed with any number of other open-drain oropen-collector products.DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1and A0 pins are gadget address inputs that are tricky wiredfor the AT24C01A and also the AT24C02.

As numerous as eight1K/2K gadgets may be tackled with a solitary bus system(unit addressing is mentioned intimately under the DeviceAddressing portion).The AT24C04 makes use of the A2 and A1 inputs for difficult wireaddressing and also a overall of four 4K gadgets may well beaddressed with a one bus procedure.

The A0 pin is ano link.The AT24C08 only utilizes the A2 enter for hardwire address-ing as well as a complete of two 8K equipment may well be resolved on asingle bus procedure. The A0 and A1 pins are no connects.The AT24C16 does not make use of the unit deal with pins, whichlimits the amount of products on the solitary bus to one.

TheA0, A1 and A2 pins aren't any connects.Create Secure (WP): The AT24C01A/02/04/16 has aWrite Defend pin that gives hardware knowledge protection.The Generate Secure pin will allow typical read/write operationswhen related to ground (GND).

Once the Generate Protectpin is related to VCC, the publish safety feature isenabled and operates as shown from the pursuing table.
