Description

The AM389x Sitara™ ARM® MPUs are a highly-integrated, programmable platform that leverages TI's

Sitara™ technology to meet the processing needs of the following applications: Single-Board Computing,

Network and Communications Processing, Industrial Automation, Human Machine Interface, and

Interactive Point-of-Service Kiosks.

The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating

systems support, rich user interfaces, and high processing performance through the maximum flexibility of

a fully integrated mixed processor solution. The device combines high-performance ARM® processing with

a highly-integrated peripheral set.

The ARM® Cortex™-A8 32-bit RISC microprocessor with NEON™ floating-point extension includes: 32K

bytes (KB) of instruction cache; 32KB of data cache; 256KB of L2 cache; and 64KB of RAM.

The rich peripheral set provides the ability to control external peripheral devices and communicate with

external processors. For details on each of the peripherals, see the related sections in this document and

the associated peripheral reference guides. The peripheral set includes: HD Video Processing Subsystem

(HDVPSS), which provides output of simultaneous HD and SD analog video and dual HD video inputs; up

to two Gigabit Ethernet MACs (10/100/1000 Mbps) with GMII and MDIO interface; two USB ports with

integrated 2.0 PHY; PCIe® port x2 lanes GEN2 compliant interface, which allows the device to act as a

PCIe® root complex or device endpoint; one 6-channel McASP audio serial port (with DIT mode); two

dual-channel McASP audio serial ports (with DIT mode); one McBSP multichannel buffered serial port;

three UARTs with IrDA and CIR support; SPI serial interface; SD/SDIO serial interface; two I2C

master/slave interfaces; up to 64 General-Purpose I/O (GPIO); seven 32-bit timers; system watchdog

timer; dual DDR2/3 SDRAM interface; flexible 8/16-bit asynchronous memory interface; and up to two

SATA interfaces for external storage on two disk drives, or more with the use of a port multiplier.

The device also includes an SGX530 3D graphics engine (available only on the AM3894 device) to

off-load many video and imaging processing tasks from the core. Additionally, it has a complete set of

development tools for the ARM which include C compilers and a Microsoft ® Windows® debugger interface

for visibility into source code execution.

The device package has been specially engineered with Via Channel™ technology. This technology

allows 0.8-mm pitch PCB feature sizes to be used in this 0.65-mm pitch package, and substantially

reduces PCB costs. It also allows PCB routing in only two signal layers due to the increased layer

efficiency of the Via Channel™ BGA technology.
