NXP MCIMX253CJM4A

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 Freescales fast, proven, power-efficient implementation of the ARM 926EJ-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.

• 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: 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.
