LC823450TA-2H General Description
Audio Audio Signal Processor 1 Channel 128-TQFP (14x14)
Key Features
- ARM® Cortex®-M3 Dual Core
- Dual Core and DSP enables parallel processing.
- I2S I/F with 16/24/32-bit, MAX 192 kHz (2-ch x 2) audio functions with 16/24/32-bit, MAX 192 kHz
- High-Resolution Audio processing capability with 32-bit 192 kHz
- Various original DSP codes for audio processing: MP3 codec, FLAC codec, Noise Cancel, Variable speed playback, etc.
- Possible to reduce DSP codes development cost.Several DSP codes are available with no additional fee such as Noise cancel, Variable speed playback, etc.
- Internal SRAM (1656K byte) for ARM® Cortex®-M3 Dual Core and original DSP
- Large scale program can be implemented by large capacity memory.
- Hard wired audio functions:
- MP3 encoder and decoder
- EQ (6-band equalizer)
- ASRC (Asynchronous Sample Rate Converter)
