DS1780E+ datasheet by Maxim Integrated Products

DS1780E+ Frequently Asked Questions (FAQs)

• What is the maximum number of devices that can be connected to the 1-Wire bus?
  The DS1780E+ can support up to 256 devices on the 1-Wire bus, but the actual number of devices that can be connected depends on the specific application and the bus capacitance.
• How do I ensure reliable communication over the 1-Wire bus?
  To ensure reliable communication, it is recommended to use a pull-up resistor on the 1-Wire bus, keep the bus length short, and minimize electromagnetic interference (EMI) and radio-frequency interference (RFI).
• What is the purpose of the VPP pin on the DS1780E+?
  The VPP pin is used to program the EPROM memory of the DS1780E+. It is not necessary for normal operation, but it is required for programming the device.
• Can I use the DS1780E+ with a 3.3V power supply?
  Yes, the DS1780E+ can operate with a 3.3V power supply, but the device's performance may be affected. The recommended operating voltage is 5V.
• How do I reset the DS1780E+?
  The DS1780E+ can be reset by pulling the RST pin low for at least 1ms. This will reset the device and clear all registers.
