ISM 868 MHz, 433 MHz and 315 MHz FSK Transmitter – Preliminary Data Sheet
ASCell3911
Rev. A, February 2000
Page 2 of 13
Austria Mikro Systeme International AG
Key Features
Supports triple band operation: Europe 868 MHz and 433 MHz-, US and Japan 315 MHz ISM
band.
Designed to be conform to EN 300 220, and FCC 47 CFR Ch.1 par.15 requirements.
Provides highly reliable packet oriented data transmission in blocks of 128 bit.
Event oriented single message transmission and status oriented and continuous message
transmission supported.
Special transmission protocol for high reliability even in presence of burst interferer (e.g.
GSM) implemented.
Supports clock for an external μC and allows clock free total shut down of the whole system.
Wide supply range between 2,2 to 3,5 V.
Low TX current, typical 8,5 mA @ 2,2 V.
Low standby current, typical 0,5 μA.
Wide operating temperature range from –40 °C to +85 °C.
Only a low cost XTAL for 25 ppm (868 MHz) or 50 ppm (433 and 315 MHz) reference fre-
quency tolerance required.
Typically only 1 XTAL, 4 capacitors and 2 inductors externally required.
General Description
The ASCell3911 is a low power, triple ISM band (868 / 433 / 315 MHz), single channel FSK
transmitter designed to work in a remote control link together with the SC3912 receiver system
cell.
The ASCell3911 performs packet oriented data transmission, in a single message- or continuos-
message mode using a special protocol to ensure high reliability even in presence of strong
pulsed interferers in close adjacent bands like e.g. GSM.
It contains a general bi-directional five line micro-controller (μC) interface to support the μC with
clock- and reset- signal and to operate the highly efficient power up/down management includ-
ing. This allows e.g. a clock-free total shut-down of the whole transmitter system.
As external components the ASCell3911 need only a reference XTAL, 4 capacitors and up to 2
inductors.
Applications
Key-less car entry systems.
Short-range packet oriented data transmission.
Security applications and alarm systems.
Domestic remote control systems.
Industrial remote control systems.
Remote metering.
