Freescale Semiconductor
Introduction
Portable DVD players
Digital cameras
The i.MX27/MX27L processor features the advanced and power-efficient ARM926EJ-S core operating at
speeds up to 400 MHz, and is optimized for minimal power consumption using the most advanced
techniques for power saving (for example, DPTC, power gating, and clock gating). With 90 nm technology
and dual Vt, the i.MX27/MX27L device provides the optimal performance vs. leakage current balance.
The performance of the i.MX27/MX27L processors are both boosted by an on-chip cache system, and
features peripheral devices, such as an MPEG-4, H.263, an H.264 video codec (up to D1—720 x 486—@
30 FPS), LCD, eMMA_lt, and CMOS Sensor Interface controllers.
The i.MX27/MX27L processors supports connections to various types of external memories, such as
266-MHz DDR, NAND Flash, NOR Flash, SDRAM, and SRAM. The i.MX27/MX27L devices can be
connected to a variety of external devices using technology, such as high-speed USBOTG 2.0, the
Advanced Technology Attachment (ATA), Multimedia/Secure Data (MMC/SDIO), and CompactFlash.
NOTE
The i.MX27L does not support the ATA-6 HDD interface.

Features
The MX27/MX27L processors are targeted for video and voice over-IP (V2IP) and smart remote
controllers. It also provides low-power solutions for any high-performance and demanding multimedia
and graphics applications.
The systems include the following features:
Multi-standard video codec (i.MX27 only)
— MPEG-4 part-II simple profile encoding/decoding
— H.264/AVC baseline profile encoding/decoding
— H.263 P3 encoding/decoding
— Multi-party call: one stream encoding and two streams decoding simultaneously
— Multi-format: encodes MPEG-4 bitstream, and decodes H.264 bitstream simultaneously
— On-the-fly video processing that reduces system memory load (for example, the
power-efficient viewfinder application with no involvement of either the memory system or the
ARM CPU)
Advanced power management (i.MX27/27L)
— Dynamic process and temperature compensation
— Multiple clock and power domains
— Independent gating of power domains
Multiple communication and expansion ports
