DS2411P+T&R

DS2411P+T&R silicon serial number is a low-cost, electronic registration number with or without an external power supply. It provides an absolutely unique identity that can be determined with a minimal electronic interface (typically, a single port pin of a microcontroller). The DS2411’s registration number is a 64-bit unique ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code (01h). Data is transferred serially through the Analog Devices 1-Wire protocol. For the DS2411, an external power supply is required, extending the operating voltage range of the device below typical 1-wire devices. The DS2411A does not require an external power supply and has a typical 1-wire operating voltage range. However, it is functionally equivalent to the DS2411, but with differing electrical parameters.

• Built-in multidrop controller enables multiple DS2411s to reside on a common 1-Wire® network
• Directly connects to a single-port pin of a microprocessor and communicates at up to 15.4kbps
• Supply voltage range from 1.5 to 5.25V
• Active supply current is 100µs maximum
• Rising edge holdoff is 1.25µs min at standard speed
• Recovery time is 5µs min at standard speed, RPUP=2.2kohm
• 6 TSOC package
• Temperature range from -40°C to +85°C
