The AM1806 ARM Microprocessor is a low-power applications processor based on ARM926EJ-S.

The device enables original-equipment manufacturers OEMs and original-design manufacturers 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. The ARM core processor has separate 16-KB instruction and 16-KB data caches. Both are four-way associative with virtual index virtual tag VIVT. The ARM core also has 8KB of RAM Vector Table and 64KB of ROM.

The peripheral set includes: one USB2.0 OTG interface; two inter-integrated circuit I2C Bus interfaces; one multichannel audio serial port McASP with 16 serializers and FIFO buffers; two multichannel buffered serial ports McBSPs with FIFO buffers; two serial peripheral interfaces SPIs with multiple chip selects; four 64-bit general-purpose timers each configurable one configurable as watchdog; a configurable 16-bit host-port interface HPI; up to 9 banks of general-purpose input/output GPIO pins, with each bank containing 16 pins with programmable interrupt and event generation modes, multiplexed with other peripherals; three UART interfaces each with RTS and CTS; two enhanced high-resolution pulse width modulator eHRPWM peripherals; three 32-bit enhanced capture eCAP module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator APWM outputs; two external memory interfaces; an asynchronous and SDRAM external memory interface EMIFA for slower memories or peripherals; and a higher speed DDR2/Mobile DDR controller.

The universal parallel port uPP provides a high-speed interface to many types of data converters, FPGAs or other parallel devices. The uPP supports programmable data widths between 8- to 16-bits on both channels. Single-data rate and double-data rate transfers are supported as well as START, ENABLE, and WAIT signals to provide control for a variety of data converters.

A video port interface VPIF is included providing a flexible video I/O port.

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 device has a complete set of development tools for the ARM processor. These tools include C compilers, and scheduling, and a Windows debugger interface for visibility into source code execution.
