Description
HN58X24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They also
have a 64-byte page programming function to make their write operation faster.
Note: Hitachi’s serial EEPROM are authorized for using consumer applications such as cellular phone,

HN58X24128I/HN58X24256I 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 ...

Page 12

HN58X24128I/HN58X24256I 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 128kbit and 256kbit EEPROMs receive 2 sequence 8-bit ...

HN58X24128I/HN58X24256I 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

HN58X24128I/HN58X24256I 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. ...
