Infineon Alarm System –Quick Start Guide
1MicroIAS
Infineon’s MicroIAS is a small form-factor board (Figure 1) designed for the use as sensor fusion based alarm
system. It employs a high accuracy pressure sensor (PS), a microphone (MIC) with high SNR and a powerful small
form-factor ARM M4F core microcontroller from Quicklogic that processes sensor data from the microphone
(listens to glass break) and the pressure sensor (picks up changes in barometric pressure after a glass break
happens) and runs sensor fusion algorithms to trigger an alarm.
The MicroIAS board allows a software developer access to all essential interfaces such as UART, SWD (CON1
connector for development and debug), power supply, a manual reset (SW1) and it provides visual aids (LED1
and LED2) for the user to identify power applied (LED1 = green) and alarm triggered (LED2 = red; blinks once for
intruder an twice for glass break).
An external power supply with a 3.6V to 6V range must be applied between GND and VCC on CON2 via a small 2-
pin micro-cable (included) to produce the board’s needed power supply (Figure 2). LED1 (green), will be lit when
the board has received the needed supply. The voltage is routed through a small LDO to generate the 1.8V needed
to power sensors (MIC and PS) as well as SPI Flash and MCU.

2Start up procedure
2.1 Connecting the MicroIAS
The purpose of the MicroIAS is that of a reference design that can be quickly built into an end application for
initial evaluation purposes. This board has a minimal number of test points and connections allowing the user
to wire this board directly into the end application for test purposes.
The board comes pre-loaded with a bootloader tailored to using the board for glass-break and intruder
functionality.
The board also has been outfitted with all the needed connections (Figure 2) to power and re-program/debug
the board as well as adjust sensitivity settings, if so desired. Refer to the more comprehensive MicroIAS User Guide
for more details on how to re-program, debug and adjust sensitivity settings.
To evaluate the board as is, no connections to CON1 need to be made (the included 10-pin ribbon cable is meant
for re-programming and/or debugging with a J-LINK debugger or similar MCU programming tool), follow these
few simple steps to setup your form-factor MicroIAS board:
Connect an external 5V power supply to CON2 via the matching black/red wire pair with receptacle (included
in the MicroIAS evaluation kit package). A battery pack, lab power supply or power bank producing a clean 5V
output voltage will suffice. Connect the red wire to 5V (do not exceed 6V, as >6V power supplies may damage
the on-board LDO used to generate the 1.8V for the sensors and the MCU) and the black wire to the ground of
your power source.
Onced powered up, LED1 (green), located between the pressure sensor and the LDO should be lit, and
indicating that power to the system has been applied. The on-board LDO converts 5V to the required 1.8V for
sensors, MCU and flash memory.
After powering up the MicroIAS, a board reset must be issued. To accomplish that, press SW1 (located below
the 2x5 Hirose connector CON1) once. It is recommended to use a pointed object for pressing the small form-
factor toggle switch. The red LED to the right of SW1 will light up once within 5s to 6s of releasing the toggle
switch SW1.
By default, the MicroIAS code is set to recognize both glass break (simulated sound via e.g. Vitron and real)
and intruder events.
oIntruder –Pressure change in the room will produce one slow blink of the red LED (LED2) located
right below the 2x5 header (CON1).
oGlassbreak –Glass break sound + instantaneous pressure change in the room will produce 2
rapid blinks of LED2
