Unit operation clock and data conversion

Unit Procedure CLOCK and Info TRANSITIONS: The SDA pin is normally pulled high having an exter-nal gadget. Info about the SDA pin may well transform only through SCL minimal time periods (refer toData Validity timing diagram).

Details improvements in the course of SCL higher periods will indicate a startor halt problem as described below.Get started Condition: A high-to-low changeover of SDA with SCL large is usually a get started conditionwhich need to precede any other command (confer with Begin and Prevent Definition timingdiagram).

Cease Condition: A low-to-high changeover of SDA with SCL superior can be a prevent condition.Immediately after a go through sequence, the quit command will position the EEPROM inside of a standby powermode (make reference to Start out and End Definition timing diagram).

Acknowledge: All addresses and data phrases are serially transmitted to and from theEEPROM in 8-bit text.

The EEPROM sends a zero to acknowledge that it hasreceived each individual word. This takes place throughout the ninth clock cycle.STANDBY Mode: The AT24C01A/02/04/08/16 features a low-power standby modewhich is enabled: (a) on power-up and (b) right after the receipt on the Cease little bit and thecompletion of any inner operations.

MEMORY RESET: Right after an interruption in protocol, electricity decline or program reset, any 2-wire element might be reset by following these techniques:one. Clock around nine cycles.2. Look for SDA substantial in every single cycle although SCL is superior.3. Make a start off ailment.
