4. Acknowledgment
The unit of data transmission is 8 bits. By turning the SDA line “L” the slave device mounted on the system
bus which receives the data during the 9th clock cycle outputs the acknowledgment signal verifying the data
reception.
When the EEPROM is rewriting, the device does not output the acknowledgment signal.
5. Device Addressing
To perform data communications, the master device mounted on the system outputs the start condition signal
to the slave device. Next, the master device outputs 7-bit length device address and a 1-bit length read/write
instruction code onto the SDA bus.
Upper 4 bits of the device address are called the “Device Code”, and set to “1010”. Successive 3 bits are
“don’t care” bits.
When the comparison results match, the slave device outputs the acknowledgment signal during the 9th clock
cycle.
In the S-24C04A, 7th bit becomes “P0”. “P0” is a page address bit and is equivalent to an additional
uppermost bit of the word address. Accordingly, when P0=”0”, the former half area corresponding to 2 kbits
(addresses from 000h to 0FFh) in the entire memory are selected; when P0=”1”, the latter half area
corresponding to 2 kbits (addresses from 100h to 1FFh) in all areas of the memory are selected.
