BCM4325 Specifications
compact small form factor solution with minimal external components to
drive the costs for mass volumes and allows for flexibility in size, form,
and function of handheld devices. The BCM4325 is designed to address
the needs of highly mobile devices that require minimal power
consumption and reliable operation.
The BCM4325 utilizes advanced design techniques and process
technology to deliver the lowest active and idle power, extending the
