Texas Instruments has announced four new Sitara ARM9 microprocessors (MPUs) and evaluation modules (EVMs) providing a variety of integrated connectivity options. The AM1808, AM1806, AM1707 and AM1705 integrate interfaces such as a serial ATA (SATA), universal parallel port (uPP) and TI’s unique programmable real-time unit (PRU). The PRU offers flexible and configurable I/O control, enabling developers to extend peripheral capabilities and add custom interfaces to their designs. The hardware and software scalability of the AM1x devices are coupled with a suite of software, demos and development tools.
The offering includes 375 and 450 MHz ARM9 options and the extended system peripherals provide the ability to implement and tune standard, custom and ‘lite’ versions of common and proprietary serial interfaces, such as UART and CAN. The PRU enhances efficiency by offloading the ARM9 to improve application processing capacity, reduce overall power consumption, eliminate latency and improve real-time responsiveness. The devices’ peripheral mix also includes USB 2.0 on-the-go (OTG) with integrated PHY, USB 1.1 with integrated PHY, 10/100 Ethernet MAC, MMC/SD and more for implementation of data, network, device and sensor communications.
