... E/W protection of critical data and/or code of block fifteen 4K blocks. Functional address lines allow the connection eight 24C65's on the same bus for up to 512K bits contiguous EEPROM memory. Advanced CMOS technology makes this device ideal for low-power nonvolatile code and data applications. ...

... A control byte is the first byte received following the start condition from the master device. The control byte con- sists of a four bit control code, for the 24C65 this is set as 1010 binary for read and write operations. The next three bits of the control byte are the device select bits (A2, A1, A0) ...

... The device select bits A2, A1, A0 can be used to expand the contiguous address space for up to 512K bits by adding up to eight 24C65's on the same bus. In this case, software can use A0 of the control byte as address bit A13 address bit A14, and A2 as address bit A15 ...

... For example, if three blocks are to be protected, the third byte would be 10XX0011. After the third byte is sent to the device, it will acknowledge and a STOP bit is then sent by the master to complete the command. During a normal write sequence attempt is made ...

... PIN DESCRIPTIONS 8.1 A0, A1, A2 Chip Address Inputs The A0..A2 inputs are used by the 24C65 for multiple device operation and conform to the two-wire bus stan- dard. The levels applied to these pins define the address block occupied by the device in the address map. A particular device is selected by transmitting the corresponding bits (A2, A1, A0) in the control byte (Figure 3-2 and Figure 8-1) ...
