The SCL input is used to positive edge clock data into EEPROM device and negative edge clock data out of each device. Maximum clock rate is 400 kHz. Serial Input/Output Data (SDA) The SDA pin is bidirectional for serial data transfer. The SDA pin needs to be pulled up by resistor as that pin is open-drain driven structure. Use proper resistor value for your system by considering VOL, IOL and the SDA pin capacitance. Except for a start condition and a stop condition which will be discussed later, the SDA transition needs to be completed during the SCL low period. Data Validity (SDA data change timing waveform) SCL SDA Data change Data change Note: High-to-low and low-to-high change of SDA should be done during SCL low period.

Device address pins are used to distinguish each device and device address pins should be connected to VCC or VSS. When device address code provided from SDA pin matches corresponding hard-wired device address pins A0 to A2, that one device can be activated. These pins are internally pulled-down to VSS. The device read these pins as Low if unconnected.

Write Protect (WP) When the Write Protect pin (WP) is high, the write protection feature is enabled and operates as shown in the following table. When the WP is low, write operation for all memory arrays are allowed. WP pin should be fixed high or low status from start condition input to stop condition input. When left unconnected, write operation for all memory arrays are allowed because the WP pin is internally pulled down to VSS. The read operation is always activated irrespective of the WP pin status.

Stop Condition A low-to-high transition of the SDA with the SCL high is a stop condition. The stand-by operation starts after a read sequence by a stop condition. In the case of write operation, a stop condition terminates the write data inputs and place the device in a internally-timed write cycle to the memories. After the internally-timed write cycle which is specified as tWC, the device enters a standby mode (See write cycle timing).

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. In the read operation, EEPROM sends a zero to acknowledge after receiving the device address word. After sending read data, the EEPROM waits acknowledgment by keeping bus open. If the EEPROM receives zero as an acknowledge, it sends read data of next address. If the EEPROM receives acknowledgment "1" (no acknowledgment) and a following stop condition, it stops the read operation and enters a stand-by mode. If the EEPROM receives neither acknowledgment "0" nor a stop condition, the EEPROM keeps bus open without sending read data.

The device address word consists of 4-bit device code, 3-bit device address code and 1-bit read/write(R/W) code. The most significant 4-bit of the device address word are used to distinguish device type and this EEPROM uses “1010” fixed code. The device address word is followed by the 3-bit device address code in the order of A2, A1, A0. The device address code selects one device out of all devices which are connected to the bus. This means that the device is selected if the inputted 3bit device address code is equal to the corresponding hard-wired A2-A0 pin status. The eighth bit of the device address word is the read/write(R/W) bit. A write operation is initiated if this bit is low and a read operation is initiated if this bit is high. Upon a compare of the device address word, the EEPROM enters the read or write operation after outputting the zero as an acknowledge. The EEPROM turns to a stand-by state if the device code is not “1010” or device address code doesn’t coincide with status of the correspond hard-wired device address pins A0 to A2.

A2 to A0 are device address and a10 to a8 are memory address. 2. R/W=“1” is read and R/W = “0” is write. Rev.2.00, Jan.11.2005, page 11 of 20 HN58X2432SI/HN58X2464SI 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 32kbit and 64kbit EEPROMs receive 2 sequence 8-bit memory address words. 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 "0". If the EEPROM receives a stop condition, the EEPROM enters an internally-timed write cycle and terminates receipt of SCL, SDA inputs until completion of the write cycle. The EEPROM returns to a standby mode after completion of the write cycle.

Rev.2.00, Jan.11.2005, page 12 of 20 HN58X2432SI/HN58X2464SI Page Write: The EEPROM is capable of the page write operation which allows any number of bytes up to 32 bytes to be written in a single write cycle. The page write is the same sequence as the byte write except for inputting the more write data. The page write is initiated by a start condition, device address word, memory address(n) and write data(Dn) with every ninth bit acknowledgment. The EEPROM enters the page write operation if the EEPROM receives more write data(Dn+1) instead of receiving a stop condition. The a0 to a4 address bits are automatically incremented upon receiving write data(Dn+1). The EEPROM can continue to receive write data up to 32 bytes. If the a0 to a4 address bits reaches the last address of the page, the a0 to a4 address bits will roll over to the first address of the same page and previous write data will be overwritten. Upon receiving a stop condition, the EEPROM stops receiving write data and enters internally-timed write cycle.

This feature is initiated by the stop condition after inputting write data. This requires the 8-bit device address word following the start condition during a internally-timed write cycle. Acknowledge polling will operate when the R/W code = “0”. Acknowledgment “1” (no acknowledgment) shows the EEPROM is in a internally-timed write cycle and acknowledgment “0” shows that the internally-timed write cycle has completed. See Write Cycle Polling using ACK. Write Cycle Polling Using ACK Send write command Send stop condition to initiate write cycle Send start condition Send device address word with R/W = 0 ACK returned Yes Next operation is addressing the memory Yes Send memory address No No Send start condition Send stop condition Proceed write operation Proceed random address read operation Send stop condition Rev.2.00, Jan.11.2005, page 14 of 20 HN58X2432SI/HN58X2464SI 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 “1”), the EEPROM outputs the 8-bit current address data from the most significant bit following acknowledgment “0”. If the EEPROM receives acknowledgment “1” (no acknowledgment) and a following stop condition, the EEPROM stops the read operation and is turned to a standby state. In case the EEPROM has accessed the last address of the last page at previous read operation, the current address will roll over and returns to zero address. In case the EEPROM has accessed the last address of the page at previous write operation, the current address will roll over within page addressing and returns to the first address in the same page. The current address is valid while power is on. The current address after power on will be indefinite. The random read operation described below is necessary to define the memory address. Current Address Read Operation Device address 32k to 64k Start 1010 R Read data (n+1) D7 D6 D5 D4 D3 D2 D1 D0 ACK R/W No ACK Stop Rev.2.00, Jan.11.2005, page 15 of 20 HN58X2432SI/HN58X2464SI 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 EEPROM outputs acknowledgment “0” after receiving memory address then enters a current address read with receiving a start condition. The EEPROM outputs the read data of the address which was defined in the dummy write operation. After receiving acknowledgment “1”(no acknowledgment) and a following stop condition, the EEPROM stops the random read operation and returns to a standby state.

Rev.2.00, Jan.11.2005, page 16 of 20 HN58X2432SI/HN58X2464SI 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. This operation can be continued as long as the EEPROM receives acknowledgment “0”. The address will roll over and returns address zero if it reaches the last address of the last page. The sequential read can be continued after roll over. The sequential read is terminated if the EEPROM receives acknowledgment “1” (no acknowledgment) and a following stop condition.

To prevent this unintentional programming, this EEPROM has a power on reset function. Be careful of the notices described below in order for the power on reset function to operate correctly. • SCL and SDA should be fixed to VCC or VSS during VCC on/off. Low to high or high to low transition during VCC on/off may cause the trigger for the unintentional programming. • VCC should be turned off after the EEPROM is placed in a standby state. • VCC should be turned on from the ground level(VSS) in order for the EEPROM not to enter the unintentional programming mode. • VCC turn on speed should be longer than 10 µs. Write/Erase Endurance and Data Retention Time The endurance is 105 cycles in case of page programming and 104 cycles in case of byte programming (1% cumulative failure rate). The data retention time is more than 10 years when a device is page-programmed less than 104 cycles. Noise Suppression Time This EEPROM have a noise suppression function at SCL and SDA inputs, that cut noise of width less than 50 ns. Be careful not to allow noise of width more than 50 ns.
