... HN58X2402SI/HN58X2404SI 2k EEPROM (256-word 8-bit) 4k EEPROM (512-word 8-bit) Description HN58X24xxSI 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 8-byte page programming function to make their write operation faster. Note: Hitachi’ ...

... HN58X2402SI/HN58X2404SI 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 to receive acknowledgment from the receiver at the ninth clock. In the write operation, EEPROM sends a zero to acknowledge after receiving every 8-bit words ...

... HN58X2402SI/HN58X2404SI 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, EEPROMs receive 8-bit memory address word. Upon receipt of this memory address, the EEPROM outputs acknowledgment "0" and receives a following 8-bit write data. After receipt of write data, the EEPROM outputs acknowledgment " ...

... HN58X2402SI/HN58X2404SI 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 the last address accessed during the last read or write operation, with incremented by one. Current address read accesses the address kept by the internal address counter. After receiving a start condition and the device address word(R/W is “ ...

HN58X2402SI/HN58X2404SI Notes Data protection at V On/Off CC When V is turned on or off, noise on the SCL and SDA inputs generated by external circuits (CPU, etc) CC may act as a trigger and turn the EEPROM to unintentional program mode. To prevent this unintentional programming, this EEPROM have a power on reset function. Be careful of the notices described below in order for the power on reset function to operate correctly ...
