The IDT P95020 features a high-fidelity audio subsystem, clock generation, resistive touch  controller, backlight LED driver, Li+/Polymer battery charger, multi-channel  DC-to-DC converters and a high resolution analog-to-digital converter (ADC). By embedding a microcontroller, the IDT P95020 offers full programmability and  flexibility into designs using leading multimedia application processors. All of  the functional blocks can be accessed via I2C. The programmable regulators  satisfy the dynamic voltage adjustment required by application processors.   

“The IDT P95020's innovative architecture, with an  embedded CPU, can manage all on-chip resources and also offload general  housekeeping and I/O processing tasks from the application processor. This  unique feature, along with programmable system power regulation blocks and an on-chip power management scheme, results in higher system performance and longer battery life,” said Farshad Zarghami, senior director of product marketing at IDT. “Building around the IDT digital heritage combined with leadership in  high-performance silicon timing, PC audio codec excellence and integration of  newly developed high-performance mixed-signal mega blocks, the IDT P95020 is the  first in a series of next-generation Intelligent System Power Management solutions being developed by IDT as part of its mixed-signal SoC growth  strategy.”

The embedded CPU utilizes on-board system management resources, such as  instrumentation SAR 12-bit ADC and a real-time clock to provide optimum  flexibility while reducing overall system power dissipation. IDT claims the P95020 PMIC  is the first of its kind to integrate all the system power regulation and  management functions along with human interface subsystems, such as audio and  touch user interfaces.  Evaluation kits, pre-defined sample scripts and the IDT GUI-based scripting tool are now available and the device, which is currently sampling to qualified customers, is priced  at $3.72 for 10,000 units.
