Maxim Integrated provides a layout and routing guide in their application note AN1441, which recommends a 4-layer PCB with a solid ground plane, and specific routing guidelines for the clock and data lines to minimize noise and crosstalk.
The DS1689S+T&R requires a stable 3.3V power supply, and decoupling capacitors should be placed as close as possible to the device. A 10uF capacitor in parallel with a 100nF capacitor is recommended for decoupling. Additionally, the power supply should be able to provide sufficient current to support the device's operating current.
The DS1689S+T&R can support clock frequencies up to 100MHz, but the maximum frequency may be limited by the specific application and system design. It's recommended to consult the datasheet and application notes for specific guidance on clock frequency selection.
The DS1689S+T&R's internal registers can be programmed using the I2C interface. The device's registers can be accessed using the I2C address, and the specific register addresses and programming sequences are detailed in the datasheet and application notes.
The typical power consumption of the DS1689S+T&R is around 10mA, but this can vary depending on the specific application, clock frequency, and operating conditions. The datasheet provides more detailed information on power consumption and power-down modes.
