PRINCIPLES OF OPERATION Power-on Reset Application of power to the X4323, X4325 activates a Power-on Reset Circuit that pulls the RESET/RESET pin active. This signal provides several benefits. – It prevents the system microprocessor from starting to operate with insufficient ...

The state of the Control Register can be read at any time by performing a random read at address FFFFh. Only one byte is read by each register read operation. The X4323, X4325 resets itself after the first byte is ...

Writing to the Control Register Changing any of the nonvolatile bits of the control reg- ister requires the following steps: – Write a 02H to the Control Register to set the Write Enable Latch (WEL). This is a volatile operation, ...

Serial Start Condition All commands are preceded by the start condition, which is a HIGH to LOW transition of SDA when SCL is HIGH. The device continuously monitors the SDA and SCL lines for the start condition and will not ...

Serial Write Operations B W YTE RITE For a write operation, the device requires the Slave Address Byte and a Word Address Byte. This gives the master access to any one of the words in the array. After receipt of ...

Serial Read Operations Read operations are initiated in the same manner as write operations with the exception that the R/W bit of the Slave Address Byte is set to one. There are three basic read operations: Current Address Reads, Ran- ...

There is a similar operation, called “Set Current Address” where the device does no operation, but enters a new address into the address counter if a stop is issued instead of the second start shown in Fig- ure 13. The ...
