BES3001-S is a USB audio single chip with USB 2.0 HS/FS Device and high performance Cortex-M4F for audio and voice
high performance application. The path from the analog input through the hardware DSP core to the analog output is
optimized for low latency.
BES3001-S integrates serial Flash for custom defined software. Users can download program by UART or USB.
BES3001-S has been designed on highest level of integration to extremely reduce the number of external component. It
is manufactured with advanced low power CMOS process and assembled with a 2.7mm*4.4mm 48-pin BGA package.
