The CAT24C256 is a 256-Kb Serial CMOS EEPROM,

internally organized as 5ꢀ2 pages of 64 bytes each, for

a total of 32,768 bytes of 8 bits each.

It features a 64-byte page write buffer and supports

both the Standard (ꢀ00 kHz) as well as Fast (400 kHz)

I²C protocol.

Write operations can be inhibited by taking the WP pin

High (this protects the entire memory).
