IM64D130AXTMA1

Microphones Overview

The IM64D130AXTMA1 is a digital MEMS microphone from Infineon Technologies, featuring an omnidirectional acoustic port and bottom sound inlet. It operates within a supply voltage range of 1.62 V to 3.6 V with a typical current consumption of 1.1 mA. The device delivers a sensitivity of -36 dBFS and a signal-to-noise ratio (SNR) of 64 dBA. It supports a maximum sound pressure level of 124 dBSPL and functions reliably across an extended temperature range from -40°C to +105°C. The component is housed in a compact TLGA-5-6 package measuring 3.5 mm x 2.65 mm x 0.98 mm.

Microphones Procurement Notes

Verify the specific ordering suffix XTMA1 to confirm tape-and-reel packaging configuration. Ensure compatibility with the target system's digital audio bus protocol before integration. Confirm that the operating environment remains within the specified -40°C to +105°C thermal limits. Check for any required pull-up resistors on the data and clock lines as per the official datasheet recommendations.

Microphones Selection Notes

Select this component when a digital output is preferred over analog to reduce noise susceptibility in PCB layout. The bottom sound port design allows for flexible mounting orientations in constrained enclosures. Consider the 1.1 mA current draw for battery-powered applications where power efficiency is critical. The wide supply voltage range offers flexibility in power domain selection.

Microphones Part Context

This part belongs to Infineon's XENSIV MEMS microphone portfolio, designed for high-fidelity audio capture. It complements other digital microphones in the series by offering a balance between size, power, and acoustic performance. The TLGA-5-6 package is optimized for surface-mount assembly in consumer and automotive electronics.

Microphones Replacement Considerations

Check for pin-compatible alternatives within the same XENSIV family if supply constraints exist. Verify that substitute parts maintain the same digital interface timing and sensitivity specifications.
