Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced the PM6650™ chip, the first member of Qualcomm's new powerOne™ family of advanced power management chips. The powerOne family of solutions interfaces directly to Qualcomm's Mobile Station Modem (MSM™) baseband processors - initially included with the MSM6250™ and MSM6500™ chipsets. This family of chips provides battery management, charging functions (including a USB charging option), voltage regulation for the various MSM power regimes, the radioOne™ RF chips and all other MSM-supported peripheral features designed for high-end, high-speed third-generation (3G) wireless products.

"The powerOne family of power management solutions offers unparalleled integration of power management functions for 3G CDMA terminals. As data rates increase, tremendous power savings can be realized through the powerOne chip's dynamic voltage scaling for MSM core blocks," said Sanjay Jha, president of Qualcomm CDMA Technologies. "The PM6650 chip and other members of the powerOne series will support all of the advanced features of our MSMs - with specific focus on MSMs offering high-end multimedia features, including MP3, camera and videophone applications, USB-OTG, R-UIM and SD Card - providing wireless manufacturers and operators with cost-effective solutions for 3G products and services."

With the power savings realized through the use of the PM6650 chip's high-efficiency step-down switch-mode power supplies (SMPSs), battery life is substantially increased. All voltages generated for the MSM and radioOne RF chips are optimized for handset system control with the applicable MSM's system software.

Power management functions for 3G CDMA terminals integrated into the PM6650 chip (and future members of the powerOne family) include:

  • Complete battery management, voltage regulation, general housekeeping and user-interface functions
  • Support for Qualcomm's radioOne ZIF chipset and all MSM-supported peripheral features
  • MSM power-on sequencing and control, and dynamic voltage scaling for maximum power savings
  • USB-OTG transceiver with host capability and integrated USB charging functionality
  • Speaker driver with programmable volume control, turn-on time and muting for driving an external 8-ohm speaker
  • SMPS voltage control for optimized PA Vdd and bias control for maximum talk-time performance
  • SMPS voltage generation for white LEDs used for color LCD backlighting
  • Linear voltage regulation for peripheral features such as R-UIM, USB, WLAN, SD Card and camera
  • Configurable Multi-Purpose Pins (MPPs) for digital or analog I/O utility functions such as general purpose LED drivers, R-UIM or SD-Card-level translation, programmable resistors or digital switches
  • On-chip Smart Thermal Control system for over-temperature protection

Samples of the PM6650 chipset are expected to be available in the third quarter of calendar 2003.
