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 I²C 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.
For Ordering Information details, see page 12.
