USB Connectivity for media storage/playback, personal media device interface, and firmware
updates
Bluetooth™ connectivity for hands free phone calling and streaming audio from wireless devices
like phones or PND
Control of the infotainment system through basic speech recognition or touch screen
Smart toll and metering applications
Secure data black box applications
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.
