The DS1631 can support up to 256 devices on the same 1-Wire bus, but it's recommended to limit it to 64 devices or less for reliable operation.
The DS1631 has a built-in power-on reset circuit that resets the device to its default state when the power supply is turned on or restored after a power failure.
The VPP (Programming Voltage) pin is used to program the device's EPROM memory. It should be connected to VCC or left unconnected during normal operation.
Yes, the DS1631 can be used in a multi-drop configuration, where multiple devices are connected to the same 1-Wire bus. Each device has a unique 64-bit ROM code that allows it to be individually addressed.
The DS1631 has a built-in temperature sensor with an accuracy of ±1°C from -25°C to +85°C. The device also has a calibration register that allows for user calibration to improve accuracy.
