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-NUCLEOCCA01M1 expansion boards can be plugged on
top of the same STM32 Nucleo host in order to
build a four-channel digital audio output system.
Features
2 channels of ternary PWM 2 x 50W @ 25V
6Ω
FFX ™ 100 dB SNR and dynamic range
I²C control with selectable device address
Digital gain +48 dB -80 dB with 0.125
dB/step
Two independent DRCs configurable as a
dual-band anti-clipper (B2DRC) or
independent
limiters/compressors
I²S input interface
3 coefficients banks for EQ preset storing
with fast recall via I²C 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
The communication between the STM32 MCU
and the STA350BW device is performed through
the I²C bus interface for setup and control
purposes and the I²S bus for digital audio
transmission. A dedicated connector is available
on the board in order to supply the power source
for the output stage.
