The recommended operating voltage range for the S-25C040A0I-T8T1U is 2.7V to 5.5V, as specified in the datasheet. However, it's essential to note that the device can tolerate a voltage range of 2.3V to 6.0V for a short duration, but prolonged operation outside the recommended range may affect its performance and lifespan.
The S-25C040A0I-T8T1U has an internal POR and BOR circuitry. The POR function resets the device when the power supply voltage rises above the POR threshold (typically 1.9V). The BOR function resets the device when the power supply voltage falls below the BOR threshold (typically 2.2V). To handle these functions, ensure that your power supply design provides a stable voltage ramp-up and ramp-down, and consider adding external circuitry to filter out noise and voltage glitches.
The S-25C040A0I-T8T1U can operate at a maximum clock frequency of 20 MHz. However, the actual clock frequency may be limited by the specific application, board design, and environmental conditions. It's essential to consult the datasheet and application notes for guidance on clock frequency selection and optimization.
To ensure data retention in the S-25C040A0I-T8T1U, follow these guidelines: 1) Use a capacitor with a minimum value of 10uF between VCC and VSS to filter out power supply noise. 2) Ensure a stable power supply voltage above 2.3V during data storage. 3) Avoid writing data to the device during power-down or low-battery conditions. 4) Consider using a battery backup or supercapacitor to maintain power to the device during power-down conditions.
The typical current consumption of the S-25C040A0I-T8T1U in active mode is around 1.5mA at 5V and 20MHz clock frequency. In standby mode, the current consumption is typically around 10uA at 5V. However, these values may vary depending on the specific application, operating conditions, and device configuration. Consult the datasheet for more detailed information on current consumption and power management.
