AS-Interface Slave IC
AS2701A (ISA3+)
Rev. C, October 2000
Page 2 of 16
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 trans-
mit/receive modes
Switching of max. 31 AS-Interface slave ICs on one bus possible
Power supply of peripheral devices from the AS-Interface slave IC of up to 35mA@24V
Only few external devices necessary for operation (quartz, 4 capacitors, E
2
PROM)
Storing of the configuration data and the slave address in one E
2
PROM
Quartz oscillator for 5.333 MHz without external capacitances
Standards: AS-Interface–Spec V2.0 and EN 50295
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.
The AS-Interface slave IC consists of the following blocks:
Receive Block
Transmit Block
Digital Logic Block
Emergency Control Block
Internal and External Power Supply with Signal decoupling
Oscillator
Power on Reset
High Voltage I/O
