CAT24C208 Datasheet, PDF (1/10 Pages) Catalyst Semiconductor – 8-Kb Dual Port Serial EEPROM

CAT24C208
8 kb Dual Port Serial
EEPROM
Description
The CAT24C208 is an 8 kb 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.
Features
• Supports Standard and Fast I²C Protocol
• 2.5 V to 5.5 V Operation
• 16−Byte Page Write Buffer
• Schmitt Triggers and Noise Protection Filters on I²C Bus Input
• Low Power CMOS Technology
• 1,000,000 Program/Erase Cycles
• 100 Year Data Retention
• Industrial Temperature Range
• SOIC 8−lead Package
• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
