... Functional address lines allow the connection eight 24C01C devices on the same bus for bits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (150 mil), and TSSOP packages ...

... The levels on these inputs are compared with the cor- responding bits in the slave address. The chip is selected if the compare is true eight 24C01C devices may be connected to the same bus by using different chip select bit combina- tions. These inputs must be connected to either V V ...

... The master device must generate an extra clock pulse which is associated with this acknowledge bit. Note: The 24C01C does not generate any acknowledge bits if an internal program- ming cycle is in progress. The device that acknowledges has to pull down the ...

... Multiple Devices The chip select bits A2, A1, A0 can be used to expand the contiguous address space for bits by add- ing up to eight 24C01C devices on the same bus. In this case, software can use A0 of the control byte as address bit A8 address bit A9, and A2 as address bit A10 ...

... Page Write The write control byte, word address and the first data byte are transmitted to the 24C01C in the same way byte write. But instead of generating a stop condi- tion, the master transmits additional data bytes to the 24C01C which are temporarily stored in the on- chip page buffer and will be written into the memory after the master has transmitted a stop condition ...

... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the stop condition for a write com- mand has been issued from the master, the device ini- tiates the internally timed write cycle ...

... Then the master issues the control byte again but with the R/W bit set to a one. The 24C01C will then issue an acknowledge and transmits the eight bit data word. The master will not acknowledge the transfer but does generate a stop condition and the 24C01C dis- continues transmission (Figure 8-2) ...
