Low Power Bottom Port Digital Silicon Microphone

DESCRIPTION

FEATURES

The WM7236 is a low-profile digital silicon microphone,

optimised for use with low-power ‘Always-on’ voice control

applications, such as Cirrus Logic^®SoundClear™

software.



High SNR (63dB)

Low variation in sensitivity (±1dB tolerance)

Low current consumption

10μA (Sleep)

The WM7236 supports two operational modes, selected

according to the applied clock frequency. ‘Voice’ mode

provides low current consumption, and sufficient SNR

performance for speech recognition algorithms. ‘Hi-Fi

Record’ mode offers wide dynamic range, and class-

leading THD performance. Operation in the ultrasonic

band is also supported at high clock frequencies.

290μA (Voice mode)

980μA (Hi-Fi Record mode)



PDM digital audio output

Stereo/array operation

Proprietary ADC technology

Reduced clock-jitter sensitivity

Low noise floor

The WM7236 incorporates Cirrus Logic proprietary

CMOS/MEMS membrane technology, offering high

reliability and high performance in a miniature, low-profile

package. The WM7236 is designed to withstand the high

temperatures associated with automated flow solder

assembly processes. (Note that conventional microphones

can be damaged by this process.)

Stable in overload condition



Bottom Port LGA Package

1.62V to 2.0V supply

APPLICATIONS

The WM7236 incorporates

a high-performance ADC,

which outputs a single-bit data stream using Pulse Density

Modulation (PDM) encoding. The WM7236 supports

selectable left/right channel assignment for a two-channel

digital microphone interface, enabling efficient connection

of multiple microphones in stereo/array configurations.



Mobile telephone handsets

Wearable devices

Portable media players

Digital cameras

Tablets and laptop computers

The WM7236 offers tight tolerance on the microphone

sensitivity, giving reduced variation between parts. This

removes the need for in-line production calibration of part-

to-part microphone variations.
