TI’s newest ARM® Cortex™-A8 microprocessors optimized for a variety of fan-less industrial and communications applications

AM387x ARM Cortex-A8 MPUs deliver high-bandwidth connectivity at 2 watts with on-board multiport Gigabit Ethernet switc

Sep 14, 2011

Dallas, Texas  (Sept. 14, 2011)   Texas Instruments (TI) (NYSE: TXN) introduced today its newest ARM® Cortex™-A8 microprocessors (MPUs), offering a total system solution with up to 1.0 GHz processing performance and a robust peripheral set at less than 2 watts power dissipation. These AM387x ARM Cortex-A8 MPUs are ideal for a variety of fan-less industrial automation, networking and communications applications, such as industrial human machine interface systems, multi-protocol industrial control, wireless access points and network attached storage.


Highly integrated devices reduce design footprint and cost

These newest MPUs offer integration of the ARM Cortex-A8 core, peripherals for high-bandwidth connectivity (SATA, D-CAN, PCI Express® (PCIe™), Gigabit Ethernet® switch and more), 3D graphics for enhanced GUIs and display subsystems for camera connectivity and viewing. In an industrial automation application controlling a production line, the AM387x ARM Cortex-A8 MPU can connect to and control IP and CAN networks, HD displays, keyboard, mouse, PC, SD card and various general purpose peripherals, all via one highly integrated processor. A high-speed, shared data bus allows for reduced communication overhead and quick access to shared data. The result is reduced chip count, discrete memory costs and printed circuit board (PCB) space compared to separate solutions.


Easy software development and compatibility protects hardware and software investments

TI’s free EZ Software Development Kit (EZ SDK) allows customers to evaluate these new MPUs in minutes and begin development in less than an hour. To differentiate products quickly and protect hardware and software investments, developers can use the EZ SDK, as well as a single evaluation module (EVM) to easily migrate between the pin-for-pin and software compatible DM814x DaVinci™ digital media processors (announced in March). Migrating from the AM387x ARM Cortex-A8 MPU to the DM814x digital media processors allows developers to add HD video to a variety of industrial applications. In an industrial automation application, developers can add video compression for storage, enabling data collection and analysis from this stored footage at a later date – in addition to the advanced system control, networking and display capabilities already provided by the ARM.



AM387x ARM Cortex-A8 MPUs offer many features to benefit customers:
