DS1311

DS131x Super Sockets are 40-pin, 0.6-inch wide DIP sockets with built-in CMOS circuitry that adds new functions to existing microcontroller-based systems. The circuits within the Super Socket are special versions of a 1-wire peripheral integrated circuit designed to support parasitic communication on a single I/O pin of the microcontroller.

The Super Socket accepts any 40-pin, single-chip microcontroller with V_CC and ground on pins 40 and 20,  espectively. When mated with a microcontroller, the Super Socket provides access to its built-in, 1-wire chip by means of a wake-up pattern that is sent via a single bidirectional I/O pin on the microcontroller. As a result, the
chip resides as a parasite on an I/O pin without encumbering the pin's normal function.

The DS131x is an effective upgrade option for previously- designed, single-chip systems and requires only slight software modification.
