MCIMX31LVKN5R2(NXP Semiconductors) 描述
Additional information about the MCIMX31LVKN5R2: The MCIMX31 and MCIMX31L multimedia applications processors represent the next step in low-power, high-performance application processors. Unless otherwise specified, the material in this data sheet is applicable to both the MCIMX31 and MCIMX31L processors and referred to singularly throughout this document as MCIMX31. The MCIMX31L does not include a graphics processing unit (GPU). Based on an ARM11 microprocessor core, the MCIMX31 provides the performance with low power consumption required by modern digital devices. The MCIMX31 takes advantage of the ARM1136JF-S core running at up to 532 MHz, and is optimized for minimal power 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 MCIMX31 provides the optimal performance versus leakage current balance. The performance of the MCIMX31 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 MCIMX31 supports connections to various types of external memories, such as DDR, NAND Flash, NOR Flash, SDRAM, and SRAM. The MCIMX31 can be connected to a variety of external devices using technology, such as high-speed USB2.0 OTG, ATA, MMC/SDIO, and compact flash.
