The recommended crystal oscillator frequency for the CC2431RTC is 32.768 kHz. This frequency is used as the clock source for the real-time clock (RTC) and is also used to generate the system clock.
To configure the CC2431RTC for low power consumption, you can use the power modes provided by the device. The CC2431RTC has three power modes: Active, Idle, and Sleep. The Sleep mode is the lowest power consumption mode, where the device consumes around 1.5 μA. You can also use the Power Down mode, which consumes around 0.5 μA. Additionally, you can disable unnecessary peripherals and use the lowest possible clock frequency to reduce power consumption.
The maximum operating temperature range for the CC2431RTC is -40°C to 85°C. However, the device can be stored at temperatures between -40°C to 125°C.
The CC2431RTC can be programmed using the IAR Embedded Workbench or the Code Composer Studio (CCS) development environment. You can also use the SmartRF Flash Programmer tool provided by Texas Instruments to program the device.
The maximum data retention period for the CC2431RTC is 10 years at a temperature of 25°C. However, this period can be affected by factors such as temperature, voltage, and storage conditions.
