WRITE PROTECT (WP): The write protect input, when connected to GND, allows normal write
operations. When WP is connected high to V
bits) of memory are inhibited. If the pin is left floating, the WP pin will be internally pulled down to
GND if the capacitive coupling to the circuit board V
recommends connecting the pin to GND.
AT24C64B, 64K SERIAL EEPROM: The 64K is internally organized as 256 pages of 32 bytes
each. Random word addressing requires a 13 bit data word address.
