38 / 53 page ![]() DC and ac parameters M25P40 38/53 10 DC and ac parameters This section summarizes the operating and measurement conditions, and the DC and AC characteristics of the device. The parameters in the DC and AC characteristic tables that follow are derived from tests performed under the Measurement Conditions summarized in the relevant tables. Designers should check that the operating conditions in their circuit match the measurement conditions when relying on the quoted parameters. Table 10. Operating conditions Symbol Parameter Min. Max. Unit VCC Supply voltage 2.7 3.6 V 2.3 3.6 V TA Ambient operating temperature (device grade 6) –40 85 °C Ambient operating temperature (device grade 3) –40 125 Table 11. Data retention and endurance Parameter Condition Min. Max. Unit Erase/Program cycles Device grade 6 100,000 cycles per sector Device grade 3 10,000 Data Retention at 55°C 20 years Table 12. Capacitance(1) 1. Sampled only, not 100% tested, at TA=25 °C and a frequency of 25 MHz. Symbol Parameter Test condition Min. Max. Unit COUT Output capacitance (Q) VOUT = 0 V 8 pF CIN Input capacitance (other pins) VIN = 0 V 6 pF |
