... SS in detail in the device addressing section. WRITE PROTECT (WP): The write protect input, when tied low to GND, allows normal write operations. Memory Organization The AT24C164 is internally organized with 256 pages of 8 bytes each. Random word addressing requires an 11 bit data word address. ...

... STOP bit and the completion of any internal operations. MEMORY RESET: After an interruption in protocol, power loss or system reset, the AT24C164 can be reset by follow- ing these steps: (a) Clock cycles, (b) look for SDA high in each cycle while SCL is high and then (c) create a start condition as SDA is high ...

... All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete (refer to Figure 2). PAGE WRITE: The AT24C164 is capable of a 16-byte page write. A page write is initiated the same as a byte write, but the microcontroller does not send a stop condi- tion after the first data word is clocked in ...
