i.MX31/i.MX31L Advance Information, Rev. 1.4

Freescale Semiconductor
Preliminary
Introduction
consumption using the most advanced techniques for power saving (DPTC, DVFS, power gating, clock
gating). With 90 nm technology and dual-Vt transistors (two threshold voltages), the i.MX31 and
i.MX31L provide the optimal performance versus leakage current balance.
The performance of the i.MX31 and i.MX31L is boosted by a multi-level cache system, and features
peripheral devices such as an MPEG-4 Hardware Encoder (VGA, 30 fps), an Autonomous Image
Processing Unit, a Vector Floating Point (VFP11) co-processor, and a RISC-based SDMA controller.
The i.MX31 and i.MX31L support connections to various types of external memories, such as 266 MHz
DDR, NAND Flash, NOR Flash, SDRAM, and SRAM. The i.MX31 and i.MX31L can be connected to a
variety of external devices using technology, such as high-speed USB2.0 OTG, ATA, MMC/SDIO, and
compact flash.
1.1
Features
The i.MX31 and i.MX31L are designed for the high-tier and mid-tier smartphone markets. They provide
low-power solutions for high-performance demanding multimedia and graphics applications.
The i.MX31 and i.MX31L are built around the ARM11 MCU core and implemented in the 90 nm
technology.
The systems include the following features:
Multimedia and floating-point hardware acceleration supporting:
— MPEG-4 real-time encode of up to VGA at 30 fps
— MPEG-4 real-time video post-processing of up to VGA at 30 fps
— Video conference call of up to QCIF-30 fps (decoder in software), 128 kbps
— Video streaming (playback) of up to VGA-30 fps, 384 kbps
— 3D graphics and other applications acceleration with the ARM
tightly-coupled Vector
Floating Point co-processor
— 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
— Dynamic voltage and frequency scaling
— Multiple clock and power domains
— Independent gating of power domains
Multiple communication and expansion ports including a fast parallel interface to an external
graphic accelerator (supporting major graphic accelerator vendors)
