The i.MX28 family of processors offers feature
integration suited for automotive infotainment
systems and gateway products. These AEC-Q100
qualified products are designed for cost-optimized
multimedia systems. The i.MX28 enables many of
the features only available in high-end systems, and
at a price point suitable for all vehicles. The core of
the i.MX28 is Freescale’s fast, power-efficient
implementation of the ARM926EJ-S™ core, with
speeds of up to 454 MHz. Integrated power
management, USB PHY, and LCD display
controller all contribute to overall system cost
savings.
The integrated power management unit (PMU) on
the i.MX28 is composed of a triple output DC-DC
switching converter and multiple linear regulators.
These provide power sequencing for the device and
its I/O peripherals such as memories and SD cards,
as well as provide battery charging capability for
Li-Ion batteries.
