IM72D128V01
IP57 dust and water resistant digital PDM XENSIVTM MEMS microphone
Description
The IM72D128V01 is an ultra-high performance digital PDM MEMS microphone designed for applications which
require a very high SNR (low self-noise) and low distortion (high AOP) and which is also IP57 robust to dust and
water.
Best-in-class signal-to-noise ratio (SNR) of 72dB(A) enables far field and low volume audio pick-up. The flat
frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of
multi-microphone (array) applications.
The digital microphone ASIC contains an extremely low-noise preamplifier and a high-performance sigma-delta
ADC. Different power modes can be selected in order to suit specific clock frequency and current consumption
requirements.
Each IM72D128V01 microphone is calibrated with an advanced Infineon calibration algorithm, resulting in low
sensitivity tolerances ( 1dB).

Environmental robustness
Infineon’s latest Sealed Dual Membrane MEMS technology delivers high ingress protection (IP57) at a
microphone level. The sealed MEMS design prevents water or dust from entering between membrane
and backplate, preventing mechanical blockage or electric leakage issues commonly observed in MEMS
microphones. Microphones built with the Sealed Dual Membrane technology can be used to create IP68
devices, requiring only minimal mesh protection.

Stereo PDM configuration
The IM72D128V01 is designed to function in circuits with one or two microphones on the PDM bus. When
two microphones are connected, data is transmitted alternately according to the L/R pin status of each
microphone. When two microphones are connected to a shared PDM bus, the power modes of both
microphones will be the same as both are controlled by the same PDM clock. The performance is unchanged
relative to a single microphone per bus configuration.

Note:
For best performance it is strongly recommended to place a 100nF (CVDD_typical) capacitor between VDD
and ground. The capacitor should be placed as close to VDD as possible. A termination resistor (RTERM
of about 100Ω may be added to reduce the ringing and overshoot on the output signal.

Footprint and stencil recommendation
The acoustic port hole diameter in the PCB should be larger than the acoustic port hole diameter of the MEMS
Microphone to ensure optimal performance. A PCB sound port size of radius 0.4 mm (diameter 0.8mm) is
recommended.
The board pad and stencil aperture recommendations shown in Figure 13 are based on Solder Mask Defined
(SMD) pads. The specific design rules of the board manufacturer should be considered for individual design
optimizations or adaptations.

Reflow soldering and board assembly
Infineon MEMS microphones are qualified in accordance with the IPC/JEDEC J-STD-020D-01. The moisture
sensitivity level of MEMS microphones is rated as MSL1. For PCB assembly of the MEMS microphone the widely
used reflow soldering using a forced convection oven is recommended.
The soldering profile should be in accordance with the recommendations of the solder paste manufacturer
to reach an optimal solder joint quality. The reflow profile shown in Figure 15 is recommended for board
manufacturing with Infineon MEMS microphones.

Reflow soldering and board assembly
The MEMS microphones can be handled using industry standard pick and place equipment. Care should be
taken to avoid damage to the microphone structure as follows:
•
•
•
•
•
Do not pick the microphone with vacuum tools which make contact with the microphone acoustic port
hole.
The microphone acoustic port hole should not be exposed to vacuum, this can destroy or damage the
MEMS.
Do not blow air into the microphone acoustic port hole. If an air blow cleaning process is used, the port
hole must be sealed to prevent particle contamination.
It is recommended to perform the PCB assembly in a clean room environment in order to avoid
microphone contamination.
Air blow and ultrasonic cleaning procedures shall not be applied to MEMS Microphones. A no-clean paste
is recommended for the assembly to avoid subsequent cleaning steps. The microphone MEMS can be
severely damaged by cleaning substances.
•
•
To prevent the blocking or partial blocking of the sound port during PCB assembly, it is recommended to
cover the sound port with protective tape during PCB sawing or system assembly.
Do not use excessive force to place the microphone on the PCB. The use of industry standard pick and
place tools is recommended in order to limit the mechanical force exerted on the package.

IM73A135
Infineon’s XENSIV™ MEMS analog microphone IM73A135 sets a new performance benchmark in MEMS microphones. A best-in-class signal to noise ratio (SNR) of 73 dB and a high acoustic overload point of 135 dBSPL enable clear audio pick up of the quietest and the loudest sounds. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level. The IM73A135 allows designers to reach a level of high audio performance that was previously only achievable by ECMs while at the same time reaping the benefits inherent in MEMS technology.

IM73D122
Ultra-low noise digital XENSIVTM MEMS microphone IM73D122 is designed for applications which require a very high SNR (low self-noise) and a high sensitivity. The flat frequency response (20Hz low-frequency roll-off) and tight manufacturing tolerance improve performance of multi-microphone (array) applications. This microphone is based on Infineon’s new Sealed Dual Membrane MEMS technology which delivers high ingress protection (IP57) at a microphone level.
