The recommended operating temperature range for the M48Z35AV-10PC1 is -40°C to +85°C, as specified in the datasheet. However, it's essential to note that the device can tolerate a wider temperature range during storage, which is -55°C to +125°C.
The M48Z35AV-10PC1 has a built-in battery voltage monitoring feature that can detect when the battery voltage falls below a certain threshold (typically 2.5V). To handle this feature, you need to connect the VBAT pin to the battery voltage and use the VRT pin to monitor the voltage level. You can then use the VRT pin to generate an interrupt or reset signal when the battery voltage falls below the threshold.
The VCC pin is the power supply pin for the internal circuitry of the M48Z35AV-10PC1. It should be connected to a stable power source, typically in the range of 3.0V to 5.5V. It's essential to ensure that the VCC pin is decoupled with a capacitor (typically 100nF) to filter out noise and prevent voltage spikes.
The M48Z35AV-10PC1 has a built-in oscillator that can be configured to operate at different clock frequencies. You can select the clock frequency by connecting the CLK pin to the desired clock source (e.g., an external crystal or a clock signal). The clock mode can be configured by setting the appropriate bits in the control register. Refer to the datasheet for more information on clock configuration and control register settings.
The maximum current consumption of the M48Z35AV-10PC1 depends on the operating mode and clock frequency. According to the datasheet, the typical current consumption is around 1.5mA at 3.3V and 32kHz clock frequency. To reduce power consumption, you can use power-saving modes, such as the sleep mode or the low-power oscillator mode. Additionally, you can reduce the clock frequency, use a lower voltage power supply, or implement power gating techniques in your design.
