The recommended PCB layout for the DS28E01P-100+T involves placing the device near the edge of the board, with the 1-Wire bus connected to a single point on the PCB to minimize noise and reflections. A ground plane under the device is also recommended to reduce electromagnetic interference (EMI).
To ensure reliable communication with the DS28E01P-100+T in a noisy environment, use a shielded cable for the 1-Wire bus, keep the bus length as short as possible, and add a 1 kΩ to 10 kΩ pull-up resistor to the 1-Wire bus. Additionally, use a capacitor (e.g., 100 nF) between the VCC and GND pins to filter out noise.
The maximum cable length for the 1-Wire bus depends on the specific application and environment. As a general guideline, the maximum cable length is approximately 100 meters, but this can be extended up to 300 meters with the use of repeaters or other signal conditioning techniques.
When communicating with the DS28E01P-100+T, implement error detection and correction mechanisms, such as CRC checks and retries, to ensure reliable data transfer. The DS28E01P-100+T also provides a built-in error detection mechanism using the 8-bit CRC byte appended to the data.
The power consumption of the DS28E01P-100+T is typically around 1.5 μA in standby mode and up to 2 mA during active operation. The device also has a low-power mode that reduces power consumption to around 0.5 μA.
