Tempe, Ariz.—Freescale Semiconductor says its MC13783 is the world's most highly integrated power management and user interface (PMUI) chip. It's billed as the successor to last-generation power-with-power-management devices that include the company's MC13790, -13883, and -13890 (see Related Links), with the MC13783 touted as a more feature-packed addition for powering voice, audio, and other media functions in 3G phones, mobile gaming units, and portable media players.
"Freescale's power management devices can reduce component count and board area by as much as 50 percent compared to many current implementations," said Mark Christensen, principal consultant at Prismark Partners. "This high level of integration is of particular importance in high-end 3G phones that must fit many features into a small form factor."
The MC13783 PMUI IC packs full audio, battery charging and lighting systems on chip. It includes five switching regulators, 18 linear regulators, USB transceiver, carkit interface, and touchscreen interface. "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."
The chip's high fidelity stereo DAC and headphone driver are designed for MP3 or personal media playback.
Voice recording and audio/music playback stages drive smart toys such as interactive dolls/animals, educational toys, and remote controlled devices. With it's flexible processor interfacing, audio system and integrated power control, the chip can be applied to voice recognition applications to give vending machines and small appliances a human-friendly interface.
Dual processor support allows for ease and flexibility in adding mobile phone capabilities to design feature-rich convergence devices. Enhanced speakerphone performance includes dual CODEC paths for noise cancellation and improved voice clarity.
The chip's USB OTG transceiver with CEA-936-A carkit provide support for transferring files, music, and graphics, or charging a battery through a shared mini-USB connector. An on-chip real time clock is included to provide calendar function with alarm capability. White LED backlight drivers for displays, keypad, flashlight, and tri-color fun lights provide complete system lighting. Touchscreen capabilities enhance the user interface.
This chip is suited to platform applications that 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 compatible with Freescale’s i.MX31 applications processor and is included in the i.MX31 application development system.
