Integrated Power Supply Reference Design for NXP i.MX 6ULL

Design Considerations
This design is intended to show the ability of the TPS6521815 PMIC to provide power to the i.MX 6ULL
processor and all of the peripheral ICs in a variety of designs. To verify this, we had to populate all of
these other ICs on the design, starting with the processor. All other devices necessary to build an
operational data concentrator or general-purpose evaluation kit are included in this section. The PMIC and
other TI devices used in this design are described in
2.2.1
Processor – i.MX 6ULL Applications Processor
The main component of this design is the NXP i.MX 6ULL processor. It is a single-core Arm
®
Cortex
®
-A7
16-bit processor. Dynamic voltage and frequency scaling (DVFS) is a highlight of the processor, wherein
the processor can change the core voltage with respect to the processing power required. The multimedia
performance of the processor is enhanced by a multilevel cache system, an ARM NEON media processor
engine (MPE) co-processor, a programmable smart DMA (SDMA) controller, an asynchronous audio
sample rate converter, an electrophoretic display (EPD) controller, and a pixel processing pipeline (PXP)
to support 2D image processing, including color-space conversion, scaling, alpha-blending and rotation.
DDR3L, eMMC, SD, QSPI, UART, and I
2
C are the processor interfaces we are using in this design.
