BelaSigna 300
Audio Processor for Portable
Communication Devices
Introduction
BelaSigna® 300 is a DSPâbased mixedâsignal audio processing
system that delivers superior audio clarity without compromising size
or battery life. The processor is specifically designed for monaural
portable communication devices requiring high performance audio
processing capabilities and programming flexibility when formâfactor
and power consumption are key design constraints.
The efficient dualâMAC 24âbit CFX DSP core, together with the
HEAR configurable accelerator signal processing engine, high speed
debugging interface, advanced algorithm security system, stateâofâ
theâart analog front end, Class D output stage and much more,
constitute an entire system on a single chip, which enables
manufacturers to create a range of advanced and unique products. The
system features a high level of instructional parallelism, providing
highly efficient computing capability. It can simultaneously execute
multiple advanced adaptive noise reduction and echo cancellation
algorithms, and uses an asymmetric dualâcore patented architecture to
allow for more processing in fewer clock cycles, resulting in reduced
power consumption.
BelaSigna 300 is supported by a comprehensive suite of
development tools, handsâon training, full technical support and a
network of solution partners offering software and engineering
services to help speed product design and shorten time to market.
Key Features
⢠Flexible DSPâbased System: a complete DSPâbased, mixedâsignal
audio system consisting of the CFX core, a fully programmable,
highly cycleâefficient, dualâHarvard architecture 24âbit DSP
utilizing explicit parallelism; the HEAR configurable accelerator for
optimized signal processing; and an efficient input/output controller
(IOC) along with a full complement of peripherals and interfaces,
which optimize the architecture for audio processing at extremely
low power consumption
⢠Ultraâlowâpower: typically 1â5 mA
⢠Excellent Audio Fidelity: up to 110 dB input dynamic range,
exceptionally low system noise and low group delay
⢠Miniature Form Factor: available in a miniature 3.63 mm x
2.68 mm x 0.92 mm (including solder balls) WLCSP package. In
addition, BelaSigna 300 is also available in a bigger DFN package
allowing easier assembly and PCB routing
⢠Multiple Audio Input Sources: four input channels from five input
sources (depends on package selection) can be used simultaneously
for multiple microphones or direct analog audio inputs
⢠Full Range of Configurable Interfaces: including a fast I2Câbased
interface for download, debug and general communication, a highly
configurable PCM interface to stream data into and out of the device,
a highâspeed UART, an SPI port and 5 GPIOs
