R0201-STC62WV5128

1. Typical characteristics are at TA = 25oC.

2. Fmax = 1/t

RC .

3. These are absolute values with respect to device ground and all overshoots due to system or tester notice are included.

4. IccSB1_MAX. is 5uA/30uA at Vcc=3.0V/5.0V and TA=70oC.

5. Icc_MAX. is 30mA(@3.0V)/70mA(@5.0V) under 55ns operation.

DATA RETENTION CHARACTERISTICS ( TA = -40 to + 85oC )

1. Vcc = 1.5V, TA = + 25OC

2. t

RC = Read Cycle Time

3. IccDR_MAX. is 0.8uA at TA=70OC.
