The SCL enter is used to positiveedge clock knowledge into each solitary EEPROM gadget and negativeedge clock details from just about every solitary device.SERIAL Information (SDA): The SDA pin is bi-directional forserial information transfer.
This pin is open-drain driven and perhaps wire-ORed with any quantity of other open-drain oropen-collector units.DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1and A0 pins are product deal with inputs that occur being tricky wiredfor the AT24C01A together together with the AT24C02.
As a number of as eight1K/2K goods may possibly be tackled that has a one bus method(equipment addressing is discussed intimately underneath the DeviceAddressing part).The AT24C04 utilizes the A2 and A1 inputs for tricky wireaddressing as well as a stuffed with 4 4K gizmos could beaddressed over the one bus method.
The A0 pin is ano hook up.The AT24C08 only performs by making use of the A2 enter for hardwire address-ing additionally to your in general of two 8K products may possibly be solved on asingle bus system. The A0 and A1 pins aren't any connects.The AT24C16 would not benefit from the machine handle pins, whichlimits the amount of equipment more than just one bus to 1.
TheA0, A1 and A2 pins are not any connects.Compose Guard (WP): The AT24C01A/02/04/16 has aWrite Guard pin that gives components understanding protection.The Generate Safeguard pin enables normal read/write operationswhen related to floor (GND).
During the event the Compose Protectpin is related to VCC, the crank out protection purpose isenabled and operates as exposed in the course of the adhering to desk.
