TI’s new $5 feature-packed Sitara™ ARM® Cortex™-A8 microprocessors enable new, robust end products while maintaining ARM9™ prices and power levels

Sitara Image New AM3352, AM3354, AM3356, AM3357, AM3358 and AM3359, Sitara ARM Cortex-A8 microprocessors (MPUs) deliver up to 720 MHz ARM Cortex-A8 performance with robust peripheral set and flexible power management modes that consume as little as 7mW of power. These MPUs are ideal for a variety of fan-less portable navigation terminals, handheld gaming devices and home and building automation control systems as well as industrial automation devices including drives and I/O-level devices, industrial PLC applications and HMI products. Optimized for system and peripheral integration, the AM335x Sitara ARM Cortex-A8 MPUs provide multiple high-performance interfaces, such as, USB2.0 w/ PHY, Gigabit Ethernet two-port switch, CAN, and more. The PRU enables real-time industrial communications capability (master and slave) supporting popular protocols, such as EtherCAT®, Ethernet/IP, PROFIBUS®, PROFINET®, POWERLINK, and SERCOS III

AM335x ARM Cortex-A8 MPUs key features include:

  • 275 - 720 MHz ARM Cortex-A8 core with high-level operating system support including Linux™ and Android™ with multiple power and performance operating points
  • Integrated high-bandwidth connectivity peripherals (USB2.0 w/ PHY, Gigabit Ethernet two-port switch, CAN, PRU, Crypto, LPDDR1/DDR2/DDR3 interfaces) for device flexibility and quick transmission of data on and off the chip while saving board space and bill of materials cost by as much as $40
  • Integrated 3D graphics and touch screen controller for advanced GUIs and touch screen interfaces
  • On-chip, production-ready, industrial Ethernet and Fieldbus communication protocols with master and slave functionality eliminate the need for an external ASIC/FPGA and save more than 30 percent on BOM costs
  • TI EZ software development kits for Linux and Android allows developers to begin evaluation within minutes and includes development software and example code into a single package with only one installation
  • AM335x ARM Cortex-A8 MPU StarterWare™ software suite provides a microcontroller-like development environment, without requiring an operating system

Extensive third party real-time operating system (RTOS) support:

  • Nucleus® RTOS from Mentor Graphics® provides full-featured, high-performance foundation on which to develop portable applications.
  • Neutrino® with graphics software from QNX Software Systems pre-loaded and optimized for the AM335x ARM Cortex-A8 MPUs to ease programming and enable applications with advanced user interfaces
  • Wind River’s VxWorks real-time operating system provides optimized support for many of TI’s ARM MPUs including the new AM335x ARM Cortex-A8 MPU generation. This added support with VxWorks offers scalability across TI’s ARM product line and provides a proven platform that reduces risk, cost and time to market for customers.

Development Tools & Software

Accompanying the AM335x ARM microprocessors are two industrial hardware development tools to enable customers to easily incorporate industrial communication standards as well as the previously announced AM335x EVM in their industrial automation products:
  1. AM335x Evaluation module (EVM) from TI is available for $995. The EVM is perfect for HMI industrial applications and includes a 7” LCD touchscreen as well as other needed interfaces and drivers.
  2. AM3359 Industrial development kit (IDK) from TI is available for $895. The IDK is an extensive development platform enabling customers to evaluate all popular industrial communications and motor control applications. IDK has many different evaluation features such as 512 MB of DDR2 memory, dual motor drivers, digital I/O, a C2000™ Piccolo microcontroller with integrated analog to digital converters, a Stellaris® ARM Cortex-M3 microcontroller, USB, Ethernet, SPI, 12C and much more.
  3. AM3359 Industrial communications engine (ICE) from TI is available for $99. It is a pocket-sized, cost-optimized and form-factor optimized reference design for I/O devices and sensors needing to add industrial communications quickly and easily.
Available to aid development is free, production-ready, certified system solution software for industrial automation protocols, including industrial design specific demos, applications notes and videos to make development easy. Software resources required for physical and data link layer implementations of many industrial communications standards are available as well as software frameworks for SYS/BIOS real-time kernel and applications stacks for industrial communication standards, allowing customers to focus on the differentiating application level aspects of their system.
