Introduction

Ordering Information

See

Table 1 on page 3

for ordering information.

The i.MX25 family of processors offers integration

that tailors itself to the connectivity requirements of

today's automobile infotainment systems. These

processors have been architected to meet auto

infotainment requirements like CAN, USB

connectivity, and audio connectivity, without many

of the extra features only needed for high-end

applications. As a result, the i.MX25 enables many

of the features only available in high-end systems,

but at a price point suitable for all vehicles.

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 automotive

versions of the i.MX25 offer AEC-Q100 grade 3

qualification to meet stringent automotive quality

requirements. The device is suitable for a wide

range of applications, including the following:

• 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

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.
