Part Details for DS1731U+T&R by Maxim Integrated Products

The recommended layout and routing for the DS1731U+T&R involves keeping the VCC and GND pins as close as possible to the device, using a solid ground plane, and minimizing the length of the VCC and GND traces. Additionally, the crystal oscillator circuit should be placed as close to the device as possible, and the crystal should be oriented to minimize noise coupling.

To ensure accurate temperature measurements, the DS1731U+T&R should be calibrated before use. The device should be calibrated at multiple temperature points, and the calibration data should be stored in the device's EEPROM. Additionally, the device should be operated within its specified temperature range, and the temperature sensor should be kept away from heat sources and thermal gradients.

The maximum clock frequency that can be used with the DS1731U+T&R is 4 MHz. However, the device can also be operated at lower frequencies, such as 1 MHz or 32 kHz, depending on the application requirements.

The DS1731U+T&R can be interfaced with a microcontroller or other digital system using a 3-wire serial interface (SCLK, SDATA, and RST). The device can be operated in either master or slave mode, and the interface can be configured to use either a push-pull or open-drain output.

The power consumption of the DS1731U+T&R depends on the operating mode and frequency. In active mode, the device consumes around 1.5 mA at 4 MHz. To minimize power consumption, the device can be operated in low-power mode, and the clock frequency can be reduced. Additionally, the device can be powered down when not in use.
