i.MX25 Applications Processor for Consumer and Industrial Products, Rev. 9

2 Freescale Semiconductor

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.
