X-NUCLEO-CCA01M1

X-NUCLEO-CCA01M1 Sound terminal expansion board based on STA350BW for STM32 Nucleo Data brief Description The X-NUCLEO-CCA01M1 is an expansion board based on the STA350BW Sound Terminal 2.1-channel high-efficiency digital audio output system. It can be plugged on top of an STM32 Nucleo board and is compatible with the ST morpho connector layout. It enables the output of digital audio streams to a speakers pairs connected directly to the board and allows the evaluation of the STMicroelectronics STA350BW digital audio output component. Up to two X-NUCLEO- CCA01M1 expansion boards can be plugged on Features top of the same STM32 Nucleo host in order to build a four-channel digital audio output system. The communication between the STM32 MCU 2 channels of ternary PWM 2 x 50W 25V 6 and the STA350BW device is performed through the IC bus interface for setup and control FFX 100 dB SNR and dynamic range purposes and the IS bus for digital audio IC control with selectable device address transmission. A dedicated connector is available Digital gain +48 dB -80 dB with 0.125 on the board in order to supply the power source dB/step for the output stage. Two independent DRCs configurable as a dual-band anti-clipper (B2DRC) or independent limiters/compressors IS input interface 3 coefficients banks for EQ preset storing with fast recall via IC interface Up to 8 user-programmable biquads per channel Free comprehensive development firmware library and example compatible with STM32Cube firmware Compatible with STM32 Nucleo boards Equipped with ST morpho connector (upward and downward) Equipped with Arduino UNO R3 connector (upward) to allow multiple board connections RoHS compliant December 2015 DocID028646 Rev 2 1/5 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram X-NUCLEO-CCA01M1 Schematic diagram Figure 1: Schematic diagram (1 of 3) Figure 2: Schematic diagram (2 of 3) 2/5 DocID028646 Rev 2
