IDT PMIC features embedded microcontroller

The architecture of the IDT P95020 features a high-fidelity audio subsystem, clock generation, resistive touch controller, backlight LED driver, Li+/polymer battery charger, multi-channel DC/DC converters and a high-resolution analogue-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 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,' said Farshad Zarghami, senior director of product marketing at IDT.

'This feature, along with programmable system power regulation blocks and an on-chip power management scheme, results in higher system performance and longer battery life,' he added.

The IDT P95020's subsystems consist of multiple switch-mode DC-to-DC converters and low-dropout (LDO) regulators, battery charge management, white LED drivers, low-power stereo audio and voice codecs with a mixer function, Class-D amplifier and headphone driver, a PLL for on-chip and off-chip clock generation and a touch-screen controller.

The embedded CPU utilises 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.

The IDT P95020 PMIC integrates all the system power regulation and management functions along with human interface subsystems, such as audio and touch user interfaces.

To help customers design next-generation devices using the IDT P95020, IDT provides evaluation kits, predefined sample scripts and the IDT GUI-based scripting tool.

The IDT P95020 is currently sampling to qualified customers and is available in a 10mm x 10mm, 132-pin QFN package and a 7mm x 7mm WCSP package.
