ON Semiconductor B300W35A109XXG

Description
BelaSigna 300 is a DSPbased mixedsignal audio processing system that delivers superior audio clarity without compromising size or battery life. It is designed for monaural portable communication devices requiring highperformance audio processing capabilities and programming flexibility when formfactor and power consumption are key design constraints.

Features
Flexible DSPbased System:
Complete DSPbased, mixedsignal audio system consisting of the CFX core, HEAR configurable accelerator, IOC, peripherals, and interfaces.
Optimized architecture for audio processing at extremely low power consumption.
Ultralowpower: Typically 15 mA
Excellent Audio Fidelity:
Up to 110 dB input dynamic range
Exceptionally low system noise
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.
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:
Fast I²Cbased interface for download, debug, and general communication.
Highly configurable PCM interface to stream data into and out of the device.
Highspeed UART.
SPI port.
5 GPIOs.
