AS2701A Datasheet As-interface Slave Ic

Manufacturer: austriamicrosystems AG

Overview: AS2701A (ISA3+) AS-Interface Slave IC Data Sheet Rev. C, October 2000 AS-Interface Slave IC AS2701A (ISA3+).

General Description

The signal transmission between the master and the slaves in the AS-Interface system is performed by a parallel two-line wire (AS-Interface line) to which the IC is connected only via a polarity protection diode and a suppressor diode.

The line is powered by a direct dc voltage of up to 33.1 V, on which data pulses with signal amplitudes of (3...8) Vpp are superimposed.

The IC extracts its own power and the power for peripherals from the line and detects the bus signals.

Key Features

  • Simple two-wire bus (AS-Interface line) Transmission of both power and signal on the AS-Interface line Decoupling of power and signal by the IC without additional external devices Transmitting protocol for using the IC and the AS-Interface master in the transmit/receive modes Switching of max. 31 AS-Interface slave ICs on one bus possible Power supply of peripheral devices from the AS-Interface sl.
