DS1244Y-70+ Frequently Asked Questions (FAQ)

  • The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal voltage regulators are powered up correctly.

  • To ensure data integrity, use a low-pass filter on the VCC and VBAT pins, and consider adding decoupling capacitors to the power supply lines. Additionally, use a shielded cable for the serial interface and consider using a common-mode choke to reduce electromagnetic interference.

  • The maximum clock frequency that can be used with the DS1244Y-70+ is 100 kHz. Exceeding this frequency may result in incorrect operation or data corruption.

  • Yes, the DS1244Y-70+ is designed for use in battery-powered devices. It has a low power consumption mode and can operate from a single lithium-ion cell or two AA batteries.

  • The DS1244Y-70+ has a built-in watchdog timer that can be enabled by setting the WDOE bit in the control register. The watchdog timer can be set to timeout after a specified period of inactivity, and can be used to reset the device or generate an interrupt.
