1.3 Description
The AM389x Sitara™ ARM^® Processors 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 processor 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.
