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.
The i.MX28 processor includes an additional 128-Kbyte
on-chip SRAM to make the device ideal for eliminating
external RAM in applications with small footprint
RTOS.
