DC AND AC PARAMETERS
This section summarizes the operating and mea-
surement conditions, as well as the DC and AC
characteristics of the device. The parameters in
the following DC and AC Characteristic tables are
derived from tests performed under the Measure-
ment Conditions listed in the relevant tables. De-
signers should check that the operating conditions
in their projects match the measurement condi-
tions when using the quoted parameters.
Table 12. DC and AC Measurement Conditions
Note: Output High Z is defined as the point where data is no longer driven.

Note: Excluding open-drain output pins; 50pF for M48T212V.
1. DQ0-DQ7
2. E1CON and E2CON
Table 13. Capacitance
Note: 1. Effective capacitance measured with power supply at 5V (M48T212Y) or 3.3V (M48T212V); sampled only, not 100% tested.
2. At 25°C, f = 1MHz.
3. Outputs deselected.
