E520.32 with high precision and low power consumption

With the E520.32, ELMOS presents a fully programmable platform for an
optical smoke detector with a bus interface. The analog, addressable
integrated circuit needs just a minimum of external components for setting
up the complete system. The E520.32 is a high current driver for the
transmitter LED and a high impedance input to voltage conversion of the
receiver diode. The component just requires the low supply current of 88µA.
4 kByte Flash ROM and 32 Byte EEPROM for configuration are integrated into
the IC.

The 2-wire bus interface supports a supply voltage of 8 to 50V. The
configurable 200mA LED driver and the wide photo current input range of 1.5
to 45nA complete the E520.32.

A fast response from the receiver and the 10 bit ADC provide for short
transmitter pulses at a high detection rate. Due to the amplifier's narrow
band pass filter characteristics, interference signals and false alarms are
avoided. The transmitter pulses and the detected signals are processed by
the integrated 8-bit microcontroller. The flexible configurability allows
an optimization of the system's performance; up to 255 detectors can be
connected to the bus interface.

The operating temperature range is -55 C to +85 C. The IC comes in a SOIC14
package.
