The maximum clock frequency for the DS12C887A is 4.5 MHz.
To ensure data integrity, use a CRC (Cyclic Redundancy Check) or checksum to detect errors during data transmission. The DS12C887A has a built-in CRC generator and checker to facilitate this.
Yes, the DS12C887A supports multi-master configuration. However, you need to ensure that each master device has a unique address and that there is a mechanism in place to prevent bus contention.
The maximum number of devices that can be connected to the 1-Wire bus is limited by the bus capacitance and the maximum allowed voltage drop. Typically, up to 300 devices can be connected, but this may vary depending on the specific application.
The DS12C887A has a built-in power-on reset and brown-out detection circuit. The device will automatically reset when the power supply voltage falls below a certain threshold (typically 3.5V) and will remain in reset until the voltage rises above this threshold.
