AM3703数据手册集成电路（IC）的微处理器规格书PDF

描述 Description

The AM37x generation (AM3715/AM3703) of Sitara™ high-performance microprocessors is based on the enhanced Cortex™-A8 device architecture and is integrated on TI's advanced 45-nm process technology. This architecture is designed to provide best in class ARM and graphics performance while delivering low power consumption.

The device can support numerous high-level operating systems and real-time operating system solutions including Linux, Android and Windows Embedded CE which are available free of charge directly from TI. Additionally, the device is fully backward compatible with previous Cortex-A8 Sitara microprocessors and OMAP™ processors.

The AM3715/AM3703 microprocessor data manual presents the electrical and mechanical specifications for the AM3715/AM3703 microprocessor.

The information contained in this data manual applies to both the commercial and extended temperature versions of the AM3715/03 Microprocessor unless otherwise indicated. It consists of the following sections:

A description of the AM3715/03 terminals: assignment, electrical characteristics, multiplexing, and functional descriptionA presentation of the electrical characteristics requirements: power domains, operating conditions, power consumption, and dc characteristics The clock specifications: input and output clocks, DPLL and DLL A description of thermal characteristics, device nomenclature, and mechanical data about the available packaging
