TI AM1806 / AM1808 Sitara ARM9™ MPUs. Texas Instruments AM1806 and AM1808 Sitara ARM9™ Microprocessors are low-power applications processors that allow you to quickly develop designs featuring robust operating systems support, rich user interfaces, and high processing performance life. TI AM1806 and AM1808 Sitara MPUs feature an ARM926EJ-S 32-bit RISC processor core that performs 32- or 16-bit instructions and 32-, 16-, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously.
The peripheral set of the TI AM1808 includes a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output (MDIO) module. It also has a SATA controller that provides a high-speed interface to mass data storage devices. Development Kits & Boards from Texas Instruments. ARM® & DSP Microprocessors. eStore – Home Page. AM335x Schematic Checklist. As you are creating the schematics for your project here are a few things to consider. Before you begin Documentation Make sure you have the latest version of documentation, especially the data sheet and silicon errata. TIP: Try searching the documentation for words such as: "must", "require", "do not", "shall", "note:", etc. Important criteria for the device will typically contain one or more of these words. This is an easy way to make sure you have not missed anything important.
TIP: - on each ti.com device product folder there is a button "Alert me about changes to this product". Pin out Have you verified that your pin labels correspond to the correct pin numbers? Critical Connections Decoupling Capacitors Voltages from traces on a printed circuit board can couple to each other in places where it is not desired, (like power supply planes). PLL and some analog supplies benefit from filters or ferrite beads to keep the noise from causing clock jitter. Power Sequencing Clocking Reset Boot modes. AM35x High-End CAN Controller (HECC) This page provides information about the controller area network (CAN). CAN is a protocol for communicating with other controllers in harsh enivornments. Both the Standard CAN Controller (SCC) and High-End CAN Controller (HECC) modules are described here. For more information, see section 6.6.6 of the Data Sheet for timing requirements and switching characteristics, and chapter 23 of the Technical Reference Manual (TRM).

Sitara ARM Cortex-A8 and ARM9 Microprocessors - AM1x ARM9 - AM1707. The device is a low-power ARM microprocessor based on an ARM926EJ-S. The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution. The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data.
The core uses pipelining so that all parts of the processor and memory system can operate continuously. The ARM core has a coprocessor 15 (CP15), protection module, and Data and program Memory Management Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and 16K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT).
The ARM core also has a 8KB RAM (Vector Table) and 64KB ROM. The device has a complete set of development tools for the ARM.
