1 Introduction
The i.MX25 multimedia applications processor has
the right mix of high performance, low power, and
integration to support the growing needs of the
industrial and general embedded markets.
At the core of the i.MX25 is Freescale's fast,
proven, power-efficient implementation of the
ARM926EJ-S core, with speeds of up to 400 MHz.
The i.MX25 includes support for up to 133 MHz
DDR2 memory, integrated 10/100 Ethernet MAC,
and two on-chip USB PHYs. The device is suitable
for a wide range of applications, including the
following:
Graphical remote controls
Human Machine Interface (HMI)
Residential and commercial control panels
Residential gateway (smart metering)
Handheld scanners and printers
Electronic point-of-sale terminals
Patient-monitoring devices
i.MX25 Applications
Processor for
Consumer and
Industrial Products
