Description

The CS48L32 is a high-performance low-power audio DSP for smartphones and other portable audio devices.

The CS48L32 combines a programmable Halo Core DSP with a variety of power-efficient fixed-function audio processors.

Features

  • Digital (PDM) output interface.
  • Halo Core™ digital signal processor.
  • Dual MAC, 100 MHz audio signal processor.
  • 280 kB program memory, 768 kB data memory.
  • Two multichannel audio serial ports (ASP), supporting data formats up to 192 kHz, 32 bits.
  • Flexible clocking configuration, incorporating a low-power frequency-locked loop (FLL).
  • FFT, LMS, and FIR accelerators Event logger with time-stamp and interrupt func.
