GENERAL DESCRIPTION
The KM681000C families are fabricated by SAMSUNG′s
advanced CMOS process technology. The families support
various operating temperature ranges and have various
package types for user flexibility of system design. The fami-
lies also support low data retention voltage for battery back-
up operation with low data retention current.
