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
