DESCRIPTION
The CAT24C208 is an 8-Kbit Dual Port Serial CMOS
EEPROM internally organized as 4 segments of 256
bytes each. The CAT24C208 features a 16-byte page
write buffer and can be accessed from either of two
separate I
2
C compatible ports, DSP (SDA, SCL) and
DDC (SDA, SCL).
Arbitration between the two interface ports is automatic
and allows the appearance of individual access to the
memory from each interface.
