64Kx8 bit Low Power CMOS Static RAM
GENERAL DESCRIPTION
The KM68512A 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
families also support low data retention voltage for battery
back-up operation with low data retention current.
FEATURES
• Process Technology: Poly Load
• Organization: 64Kx8
• Power Supply Voltage: 4.5~5.5V
• Low Data Retention Voltage: 2V(Min)
• Three state output and TTL Compatible
• Package Type: 32-SOP-525, 32-TSOP1-0820F
