for ordering information.
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

Features of the i.MX25 processor include the following:
• Advanced power management—The heart of the device is a level of power management
throughout the IC that enables the multimedia features and peripherals to achieve minimum system
power consumption in active and various low-power modes. Power management techniques allow
the designer to deliver a feature-rich product that requires levels of power far lower than typical
industry expectations.
• Multimedia powerhouse—The multimedia performance of the i.MX25 processor is boosted by a
16 KB L1 instruction and data cache system and further enhanced by an LCD controller (with
alpha blending), a CMOS image sensor interface, an A/D controller (integrated touchscreen
controller), and a programmable Smart DMA (SDMA) controller.
• 128 Kbytes on-chip SRAM—The additional 128 Kbyte on-chip SRAM makes the device ideal for
eliminating external RAM in applications with small footprint RTOS. The on-chip SRAM allows
the designer to enable an ultra low power LCD refresh.
• Interface flexibility—The device interface supports connection to all common types of external
memories: MobileDDR, DDR, DDR2, NOR Flash, PSRAM, SDRAM and SRAM, NAND Flash,
and managed NAND.
• Increased security—Because the need for advanced security for tethered and untethered devices
continues to increase, the i.MX25 processor delivers hardware-enabled security features that
enable secure e-commerce, Digital Rights Management (DRM), information encryption, robust
tamper detection, secure boot, and secure software downloads.
• On-chip PHY—The device includes an HS USB OTG PHY and FS USB HOST PHY.
• Fast Ethernet—For rapid external communication, a Fast Ethernet Controller (FEC) is included.
• i.MX25 only supports Little Endian mode.
