AM2732集成電路（IC）的微處理器規(guī)格書PDF中文資料

AM2732屬于集成電路（IC）的微處理器。由德州儀器制造生產的AM2732微處理器微處理器產品是用于信息和數(shù)據處理的集成電路。與主要按照制造商所選術語而視為微控制器的類似產品相比，這些器件有所不同。但是按照傳統(tǒng)，微處理器不會在設備內集成工作存儲器，不太可能集成混合信號外設，并且可能在更為復雜的軟件范式下使用，這些范式涉及使用操作系統(tǒng)來管理多任務同時執(zhí)行。

3 Description

The AM273x family of microcontrollers are highly-integrated, high-performance microcontrollers based on the

Arm Cortex-R5F and a C66x floating-point DSP cores. The device enables original equipment manufacturers

(OEM) and original design manufacturers (ODM) to quickly bring to market devices with robust software support,

rich user interfaces, and high performance. The device offers the maximum flexibility of a fully integrated, mixed

processor design.

With an integrated Hardware Security Module (HSM), functional safety support built in, large, integrated RAM

on die, and a wide temperature range, the AM273x offers a safe, secure and cost effective design for many

industrial and automotive applications.

The AM273x device is provided as part of a complete platform including hardware reference designs, software

drivers, DSP library, sample software configurations/applications, API guide, and user documentation.
