1.3 Description
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.
