GENERAL DESCRIPTION
The K6X4016T3F families are fabricated by SAMSUNG′s
advanced CMOS process technology. The families support var-
ious operating temperature range and have 44-TSOP2 pack-
age type for user flexibility of system design. The families also
support low data retention voltage for battery back-up operation
with low data retention current.
