DESCRIPTION

The CAT24WC32/64 is a 32K/64K-bit Serial CMOS

E²PROM internally organized as 4096/8192 words of 8

bits each. Catalyst’s advanced CMOS technology sub-

stantially reduces device power requirements. The

CAT24WC32/64 features a 32-byte page write buffer.

The device operates via the I²C bus serial interface and

is available in 8-pin DIP or 8-pin SOIC packages.
