256Kx8 bit Super Low Power and Low Voltage Full CMOS Static RAM

GENERAL DESCRIPTION

The K6F2008U2E families are fabricated by SAMSUNG

′s

advanced Full CMOS process technology. The families support

various operating temperature ranges and have various pack-

age types for user flexibility of system design. The families also

supports low data retention voltage for battery back-up opera-

tion with low data retention current.

FEATURES

• Process Technology: Full CMOS

• Organization: 256Kx8

• Power Supply Voltage: 2.7~3.3V

• Low Data Retention Voltage: 1.5V(Min)

• Three State Outputs

• Package Type: 32-TSOP1-0813.4F, 48(36)-TBGA-6.00x7.00

PRODUCT FAMILY

1. The parameter is measured with 30pF test load.

2. Typical values are measured at VCC=3.0V, TA=25

°C and not 100% tested.
