Freescale’s Single Chip Powers Voice Recording, Audio/Music Playback, and MoreDecember 04, 2005 by Jeff Shepard
Freescale Semiconductor has targeted the increasing demands to power new features in today's smart mobile devices with the introduction of the world's most highly integrated power management and user interface (PMUI) chip.
With this single-chip device, designers can optimize system power and drive a variety of powerful audio and multimedia features in products such as 3G phones, mobile gaming units and portable media players. The Freescale PMUI includes a full audio system, battery charger system, lighting system, five switching regulators, 18 linear regulators, USB transceiver, carkit interface, touchscreen interface and more.
"As the capabilities of mobile devices such as 3G handsets continue to expand, developers encounter more challenges with product size and battery life," said Franz Fink, senior vice president and general manager of Freescale's Wireless and Mobile Systems Group. "This device addresses both issues with an unmatched level of integration and power control. We're enabling OEMs to push the envelope of product sophistication, form factor and function."
Features of the MC13783 include: dynamic voltage scaling, multi-mode switching regulators, user off support with power interruption recovery, Li Ion battery charger, coin cell battery back-up and a USB OTG transceiver with CEA-936-A carkit support for transferring files, music and graphics or charging a battery through a shared mini-USB connector.
The MC13783 is the latest in a series of Freescale PMUI products offered as individual ICs or as part of total platform solutions. Platform applications include Freescale's 3G Innovative Convergence™ i.300-30 and Mobile eXtreme Convergence MXC300-30 as well as the MXC275-30 EDGE solution. In addition, the device is ideally suited for Freescale's i.MX31 applications processor and is included in the i.MX31 application development system.
The MC13783 is sampling now, with general availability expected in February 2006. Reference designs and development assistance are available today.
