PSoC 6 I2S Feature

Posted by MichiyukiY_91 Jun 6, 2017



Here is an update on the PSoC 6 I2S feature we have.

PSoC 6 has one I2S hardware block able to produce/receive digital audio streaming data to/from external I2S devices, such as audio codecs, microphones or simple DACs. The frames generated by the IP can be configured to generate data word length of 8-bit/16-bit/18-bit/20-bit/24-bit/32-bit per channel. The channel length is also configurable. The hardware IP provides two hardware FIFO buffers, one each for the Tx block and Rx block. Any writes and reads to/from the FIFOs can be handled by DMAs or CPU.
