with Partial Array Write
Protection
Description
The CAT24WC66 is a 64−Kb Serial CMOS EEPROM internally
organized as 8192 words of 8 bits each. ON Semiconductor’s
advanced CMOS technology substantially reduces device power
requirements. The CAT24WC66 features a 32−byte page write buffer.
The device operates via the I
2
C bus serial interface and is available in
8−pin PDIP or 8−pin SOIC packages.
