HN58X24512I Acknowledge All addresses and data words are serially transmitted to and from in 8-bit words. The receiver sends a zero to acknowledge that it has received each word. This happens during ninth clock cycle. The transmitter keeps bus open ...
Page 11
Device Addressing The EEPROM device requires an 8-bit device address word following a start condition to enable the chip for a read or a write operation. The device address word consists of 4-bit device code, 3-bit device address code and ...

HN58X24512I Write Operations Byte Write: A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends acknowledgment "0" at the ninth clock cycle. After these, the EEPROM receives 2 sequence 8-bit memory address words. ...

Page Write: The EEPROM is capable of the page write operation which allows any number of bytes up to 128 bytes to be written in a single write cycle. The page write is the same sequence as the byte write ...

HN58X24512I Acknowledge Polling: Acknowledge polling feature is used to show if the EEPROM internally-timed write cycle or not. This features is initiated by the stop condition after inputting write data. This requires the 8-bit device address word ...
Page 15
Read Operation There are three read operations: current address read, random read, and sequential read. Read operations are initiated the same way as write operations with the exception of R/W = “1”. Current Address Read: The internal address counter maintains ...
Page 16
HN58X24512I Random Read: This is a read operation with defined read address. A random read requires a dummy write to set read address. The EEPROM receives a start condition, device address word (R/W=0) and memory address 2 8-bit sequentially. The ...
Page 17
Sequential Read: Sequential reads are initiated by either a current address read or a random read. If the EEPROM receives acknowledgment “0” after 8-bit read data, the read address is incremented and the next 8-bit read data are coming out. ...
