In a stereoframe there are 64 SCK cycles, or 32 SCK cycles per data-word. When L/R=0, the output data in the left channel, while L/R=Vdd, data in the right channel. The output data pin (SD) is tri-stated after the LSB is output so that another microphone can drive the common data line. DATA WORD LENGTH The output data-word length is 24 bits per channel. The Mic must always have 64 clock cycles for every stereo data-word(fSCK=64 x fWS). DATA WORD FORMAT The default data format is I²S, MSB-first. In this format, the MSB of each word delayed by one SCK cycle from the start of each half-frame. cuidevices.com Additional Resources: Product Page | 3D Model | PCB Footprint CUI Devices │ MODEL: CMM-4030D-261-I2S-TR │ DESCRIPTION: MEMS MICROPHONE date 11/01/2021 │ page 4 of 8 ENVIRONMENTAL parameter conditions/description min operating temperature storage temperature in packaging RoHS yes max units -20 typ 70 °C -40 100 °C max units MECHANICAL parameter conditions/description dimensions 4.0 x 3.0 x 1.25 acoustic port top terminals surface mount min typ mm weight 0.03 g MECHANICAL DRAWING units: mm tolerance: length, width, height: ±0.10 mm acoustic port: ±0.05 mm unless otherwise specified: ±0.15 mm TERMINAL CONNECTIONS TERM. SYM FUNCTION DESCRIPTION 1 GND ground 2 N/C -- 3 WS input Serial Data-Word Select for I²S Interface. 4 CHIPEN input Microphone enable. When set low(ground), the microphone is disabled and put in power-down mode. When set high (VDD), the microphone is enabled. 5 L/R input Left/Right Channel Select. When set low, the microphone outputs its signal in the left channel of the I²S frame; when set high, the microphone outputs its signal in the right channel. 6 SCK input Serial Data Clock for I²S Interface. 7 SD output Serial Data Output for I²S Interface. This pin tristates when not actively driving the appropriate output channel. The SD trace should have a 100 kΩ pull-down resistor to discharge the line during the time that all microphones on the bus have tristated their outputs. 8 VDD power 1.8 to 3.3 V. This pin should be decoupled to Pin 1 with a 0.1 μF capacitor and a 10 µF capacitor. Connect to ground on the PCB.
