TI introduces Sitara AM335x ARM microprocessors, the industrys first $5 high-performance, feature-packed ARM Cortex-A8 devices

Boost existing ARM9 designs with 3D graphics, touch screens, Gigabit Ethernet, high-bandwidth connectivity and more without increasing cost or power

DALLAS (Oct. 31, 2011) — Imagine upgrading from ARM9-based product designs to add 3D interactive touch screens, higher resolution displays, faster performance and multiple, flexible integrated connectivity options for a more robust offering — all while keeping design costs and power levels low. Visualize taking these new products to market in six months with an inexpensive development platform and free, complete software development kit. Texas Instruments Incorporated (TI) now makes this design vision a reality with its new Sitara AM335x ARM Cortex-A8 microprocessors.

"The new Sitara AM335x ARM Cortex-A8 microprocessors from TI allow designers to explore infinite possibilities for upgrading their systems without increasing cost or power consumption," said Dipti Vachani, general manager, Sitara ARM microprocessors, TI. "Moreover, TI gives you all the tools, free software and 24/7 support to design. That's true design ease — paramount to every TI embedded processor offering."

Starting at $5 and consuming as low as 7 mW of power, the AM335x ARM Cortex-A8 microprocessors provide low power consumption, prolonging battery life and reducing heat emissions, to enable portable, pocket-sized, fan-less applications. Offering developers high performance with advanced 3D graphics capabilities, touch screen controller and sophisticated peripherals all on a single chip reduces printed circuit board (PCB) space, complexity and bill of materials (BOM) costs by as much as $40 for smaller sized applications such as portable navigation, handheld gaming and educational devices, home and building automation and more.

“TI's feature-packed AM335x ARM microprocessors and the associated software and hardware development boards provide embedded system designers with low-cost, low-power and easy-to-use solutions,” said Jim McGregor, chief technology strategist, In-Stat. “Total system solutions like these allow embedded designers to take advantage of the huge investments in ARM core technology and open source software, such as the Android operating system, to ensure a roadmap for future investments in silicon and software."

Begin development with an $89 open source development board or complete evaluation module

The AM335x ARM Cortex-A8 microprocessors offer multiple robust development tools. Designers can quickly and easily begin development with the $89 BeagleBone, the newest, best-value open source hardware platform from the community. Designers can also use the full-featured AM335x evaluation module (EVM) with a seven-inch LCD touch screen and access to all peripherals for $995. The EVM includes TI’s WL1271 single-chip 802.11b/g/n + Bluetooth technology in a broadly available module and is the first widely available platform to enable Wi-Fi Direct. The combination of the AM335x ARM Cortex-A8 microprocessors and proven WL1271 solution provides a very low-cost, high-performance wireless connectivity platform.

Software supports popular OSes and enables microcontroller-like programming

Accompanying both the BeagleBone and full-featured EVM are a host of software solutions:

  • TI EZ software development kit, allowing demo in minutes and development in less than an hour
  • Support for Linux, Android and Windows Embedded Compact 7 operating systems
  • Compatible security solutions and real-time operating systems (RTOSes) available from third parties, enabling further product customization and simplifying development
  • StarterWare software stack allowing developers to program these microprocessors like a microcontroller, without requiring an operating system

Together these software offerings permit developers to scale the ARM platform, from MCUs to ARM9 devices, ARM Cortex-A8 devices, ARM + DSP devices, as well as video processors and DSPs, saving time and cost.

Pricing and availability

Developers can begin evaluation of the AM335x ARM Cortex-A8 microprocessors with the $89 BeagleBone from They can also develop on TI’s full-featured EVM (TMDXEVM3558) for $995, available December 2011. TI’s Linux EZ SDK and support for Android 2.2 are available for FREE download from December 2011 with Windows Embedded Compact 7 support coming in 1Q2012. Support for QNX, Mentor and Wind River third-party, RTOSes will be available starting this quarter. These devices (XAM3358ZCE and XAM3359ZCZ) are sampling today. Prices for the AM335x ARM Cortex-A8 microprocessors begin at $4.99 (in 100,000 unit quantities). Application-specific reference designs based on the AM335x ARM Cortex-A8 microprocessors will be available later this year and into 2012.
