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
